SAN FRANCISCO – Under a new National Oceanic and Atmospheric Administration six-month study contract, Maxar Technologies will explore the application of its Legion-class satellite to weather observation from low Earth orbit.

“This is not just a technical study, it’s more programmatic,” Al Tadros, Maxar vice president of space infrastructure and civil space, told SpaceNews. “How do you develop and deploy a capability? How do you refresh technologies on a regular basis?”

NOAA is awarding a series of study contracts to explore potential instruments, spacecraft, business models and mission concepts for a space-based architecture to succeed the Joint Polar Satellite System and GOES-R series. As of June 2, NOAA had awarded 26 contracts for analyses of instrument and mission concepts. Fourteen of the contracts fund studies related to geostationary and extended orbits. Another 12 studies focus on low Earth orbit sounding.

For the low Earth orbit architecture study, Maxar is exploring the idea of integrating NOAA weather sensors on Legion-class satellite buses, under a $350,000 NOAA contract awarded May 25. Maxar would then own and operate the satellite constellation, leveraging much of the same ground infrastructure that it will use for its WorldView Legion remote sensing constellation to supply NOAA with weather data.

Maxar plans to launch the first block of six satellites into its WorldView Legion next-generation Earth imagery constellation in 2021. The WorldView Legion constellation is designed to collect land imagery from a variety of orbits to offer customers the ability to frequently observe specific locations.

There are “similarities in terms of coverage, resolution and pointing precision” between the requirements of Earth imagery and NOAA weather data customers, Tadros said. “There’s a lot that we have invested in [WorldView] that we can bring to a NOAA mission.”

Maxar won another NOAA study contract related to geostationary orbit.

Under that award, the company will flesh out the idea of supplying NOAA with Maxar’s commercial geostationary satellite bus, integrating the payload, arranging the launch and handing payload operations.

Whether NOAA wanted to follow a hosted-payload model or fly its geostationary instruments on a dedicated satellite, “there is a substantial capability in the commercial industry that can benefit NOAA in terms of cost, schedule and technology refresh,” Tadros said.

Under a NASA contract, Maxar is preparing to install NASA’s Tropospheric Emissions: Monitoring Pollution sensor as a hosted payload on a commercial communications satellite scheduled to travel to geostationary orbit in 2022.

After the SpaceX rideshare, BlackSky has another four satellites booked to launch on India’s new Small Satellite Launch Vehicle this year, though delays with that program have made a launch date unclear, Merski said.

WASHINGTON — Earth-observation company BlackSky will launch two satellites as co-passengers on a SpaceX Starlink mission expected to occur June 24, Nick Merski, vice president of space operations for Spaceflight Industries, told SpaceNews.

Spaceflight’s rideshare business Spaceflight Inc. is arranging the launches for BlackSky, said Merski, who is responsible for supporting BlackSky and formerly directed the BlackSky constellation program. 

After the SpaceX rideshare, BlackSky has another four satellites booked to launch on India’s new Small Satellite Launch Vehicle this year, though delays with that program have made a launch date unclear, Merski said. 

BlackSky has four satellites in orbit from launches in 2018 and 2019 that were built in-house by Spaceflight Industries. The company hopes to have 16 satellites in low Earth orbit by early 2021.

LeoStella, a joint venture of Spaceflight Industries and Thales Alenia Space, is building 20 satellites under a contract with BlackSky, some of which will replace older satellites to maintain a 16-satellite constellation, Merski said. 

Merski said the LeoStella-built satellites feature improvements in manufacturability, a rapidly commissionable imaging payload and steam-powered propulsion units from Bradford Space. Each satellite weighs 55 kilograms and is designed for a three-year service life, he said. 

BlackSky, through Spaceflight Inc., is still arranging launches for another six satellites it hopes to have in orbit in less than a year. Merski said launch opportunities have become more numerous for smallsat operators, making later launch contracts more manageable. 

“The market is changing so you don’t have to book all these launches 24 months in advance,” he said. “We’ve got plans laid in place in pretty advanced negotiations with a couple different providers.”

BlackSky is late on its LeoStella payments, according to Intelsat, which loaned BlackSky $50 million last year. Merski declined to say when BlackSky will catch up on payments, but said LeoStella is continuing to build its satellites. 

BlackSky has a long-term goal of operating a 60-satellite constellation. Merski said the company will pursue that number based on market demand for its optical imagery. With 16 satellites, BlackSky can provide 1-meter resolution imagery with hourly revisit times for most major cities, he said. A constellation of 60 satellites would shorten revisit times to 10 to 15 minutes, and sharpen resolution to under one meter, he said. 

BlackSky has a ground network of six gateway stations, one the company built and five it uses through leases, some of which BlackSky installed equipment at, Merski said. By mid-2022, BlackSky anticipates having 10 gateway stations through a mix of partnerships and fully-owned stations, he said.

大庄家彩票平台Virgin Orbit in Mojave

WASHINGTON — Virgin Orbit and the British government are continuing efforts to begin flights of the company’s air-launch system from an English airport by early 2022 despite challenges on both sides of the Atlantic.

Virgin Orbit and the U.K. Space Agency, along with Spaceport Cornwall, held an online suppliers conference June 4 to provide an update about the company’s plans to operate from the southwestern England spaceport, also known as Cornwall Airport Newquay, using its LauncherOne rocket and modified Boeing 747 carrier aircraft.

“We’re confident that we can get to that end goal of that launch towards the end of ’21 or early ’22,” said Miles Carden, spaceport director for the Cornwall Council, which has helped fund infrastructure improvements to the airport in partnership with Virgin Orbit and the U.K. Space Agency.

The main purpose of the meeting was to discuss Virgin Orbit’s procurement of some of that launch infrastructure from British companies. The company will issue a request for proposals in July for a transportable ground operations system, or TGOS, a collection of tanks, generators and other systems used to fuel and prepare the LauncherOne rocket.

The new TGOS, to be manufactured in Britain, will be a portable version of Virgin Orbit’s existing ground support equipment in California that is too large to transport by air. 大庄家彩票平台 officials said at the meeting that TGOS is designed to fit into a cargo version of a 747 with a front-loading door, with enough room to also accommodate two LauncherOne rockets and payloads.

Virgin Orbit expects to select a prime contractor for TGOS by late September, with the goal of having the system certified for use on LauncherOne missions a year later. The company, though, didn’t commit to a specific date for a first launch from Cornwall.

Development of LauncherOne continues after the company’s first launch failed to reach orbit May 25. The LauncherOne rocket successfully separated from the 747 and ignited its engine, but the engine shut down several seconds into flight.

“About 9 seconds after drop, something malfunctioned, causing the booster stage engine to extinguish, which in turn ended the mission,” the company said in a May 27 statement about the launch. “We cannot yet say conclusively what the malfunction was or what caused it, but we feel confident we have sufficient data to determine that as we continue through the rigorous investigation we’ve already begun.”

大庄家彩票平台 officials didn’t offer new details about the malfunction at the supplier meeting. “We learned a lot, and we’re continuing to learn as we review the data,” said Derrick Boston, chief administrative officer and general counsel of Virgin Orbit, noting that the next LauncherOne rocket is “nearing completion” with several more in various stages of production.

Enabling Virgin Orbit launches from Cornwall also requires work on U.K. launch regulations. During the meeting, participants noted that draft legislation that would allow horizontal launch systems like Virgin Orbit’s was due in March but has yet to be released.

Ian Annett, deputy chief executive of the U.K. Space Agency, said discussions are ongoing with various government agencies, including the Department for Transport. “Clearly, the government’s focus for the moment is on resolving the current pandemic, and therefore legislation that is passing through Parliament is predominantly related to the pandemic, and also, of course, to the E.U. transition,” he said, a reference to the U.K.’s departure from the European Union.

Annett said the U.K. Space Agency was continuing to work with other agencies on the legislation, but didn’t commit to a specific date when it would be released. “My sense is that it’s not a critical path item at the moment,” he said.

A trusted attribution process underpins a credible deterrence strategy.

]]>
大庄家彩票平台

What is often overlooked in today’s space strategies and policies is the need for a robust space attribution process. That is the ability to trace the origin of an action against space architectures. Without being able to determine the origin or source of a hostile or malicious action, the ability to respond appropriately seems doubtful.

A credible and trusted attribution process underpins a successful deterrence strategy.

Using lessons from the nuclear community and insights from decades of experience operating in the space domain, a sound space attribution framework should include data and information from multiple sources. Attribution should be thought of as a process, not as a singular event or piece of knowledge.

Because of the relative newness of space as a warfighting domain, it can be helpful to consider attribution frameworks from other efforts. In particular, space attribution can benefit from considering nuclear forensics and attribution. The process incorporates data and information from , the intelligence community (IC) and to inform national leadership on the origin of source material and technology used in a nuclear detonation.

大庄家彩票平台A useful framework for attribution in the space domain should not be expected to look exactly the same as that used for nuclear attribution because of, in part, the international nature of space and differences between the operational environments. So, taking into account an understanding from the nuclear community that a broad and coordinated attribution framework works best, along with insights from decades of operational experience within the space domain, a practical space attribution framework should include space situational awareness (SSA) and forensic science capabilities, the IC, allies and commercial partners.

Space situational awareness, space forensics

SSA, along with the associated space domain awareness, is the linchpin for the space attribution process. According to U.S. joint doctrine, space situational awareness refers to the “requisite foundational, current, and predictive knowledge and characterization of space objects and the operational environment upon which space operations depend.”

Capabilities for SSA exist today and can be governmental and commercial in nature. For example, the Space Surveillance Network, including Space Fence and the , currently supports SSA collection and dissemination. Commercial companies such as AGI, ExoAnalytics, and LeoLabs support the collection, interpretation, and dissemination of SSA data and information. To increase SSA transparency, U.S. Space Command’s internet portal space-track.org is used for sharing space situational awareness services and information among governmental, commercial, and academic entities.

Despite its importance, SSA alone is not enough to enable space attribution. For example, while many of today’s SSA ground and space-based capabilities may be used for collection against kinetic actions — such as direct ascent and co-orbital anti-satellites — additional capabilities are needed to more effectively collect against non-kinetic actions, such as jamming, lasing, and network attacks. In particular, forensic science capabilities will improve the process of attributing non-kinetic actions in space.

As used here, space forensics refers to the science of analyzing and determining the source and pathway of an attack against space architectures after such an attack has occurred. Space forensics includes scientific methods to gather data and information from satellites, ground systems, and associated networks regarding actions that are non-kinetic or kinetic, and reversible or non-reversible. Because many space architectures use networks and computers, the required forensic evidence may include digital forensics and signatures — or “electronic fingerprints” — received through space, ground, and user segments.

For attacks or hostile actions in space, the attribution process may lead to a military response. Yet for less serious acts in space, attribution may lead to prosecution through civilian courts or diplomatic admonishment. Because of the possible need for space forensics evidence to be deemed admissible in a court of law, collected forensics data should remain pristine, using law enforcement chain of custody procedures. As a result, the Federal Bureau of Investigation (FBI) may need to be part of the space forensics evidence collection, while also potentially including International Criminal Police Organization (INTERPOL).

Any military and law enforcement cooperation will need to observe U.S. federal law regarding posse comitatus, or the general prohibition of military personnel from direct participation in law enforcement activities.

Role of intelligence community

Per the IC collects information needed by the president, the National Security Council, the Secretaries of State and Defense, and other Executive Branch officials for the performance of their duties; produces and disseminates intelligence; and collects information concerning hostile activities directed against the United States.

Commensurate with its , the IC should support the space attribution process in gathering raw data and information, analyzing that data and information in context, and producing timely and relevant products. The intelligence gathered will be used to inform how, where, and when harmful interference or an attack against U.S. space architectures occurs.

Using current organizational structures, the National Space Defense Center (NSDC) is well-suited for coordinating IC input into the space attribution process. Regarding its roles and mission, the NSDC is said to be “a partnership organization, strongly supported by both the Department of Defense and Intelligence Community, that develops and improves U.S. ability to rapidly detect, warn, characterize, attribute and defend against threats to our nation’s vital space systems.” The NSDC is stated to be the first serious effort to combine military and IC community resources to gather and share data about possible threats to U.S. satellites and supporting infrastructure.

Allies and commercial partners

Because of the global reach and international nature of the space domain, allies and commercial partners must be part of a space attribution framework. Including allies and commercial partners will greatly increase the sharing of SSA, intelligence collection, and forensics science data.

The existing (FVEY) intelligence alliance — Australia, Canada, New Zealand, the United Kingdom and United States — will be helpful for space attribution and intelligence sharing. Each country brings geographically specific or distinct tasking, collection, processing, exploitation, and dissemination methods that benefit the alliance and a possible response to harmful interference or attack. Furthermore, the initiative, which currently includes representatives from the FVEY partners plus France and Germany, seeks to enhance space collaboration by discussing operational concepts and infrastructure requirements.

Commercial partners will also enhance the space attribution process, because of the sheer number of commercial small satellites presently operating, along with those constellations planned for the future. The ongoing growth in proliferated low Earth orbit satellites has led to large commercial constellations performing communications, Earth observation, change detection, data analytics, and other activities. Some commercial satellite communication providers may have comprehensive knowledge and digital forensics capabilities concerning interference and attacks against their networks and those of other satellite operators, which can be used to inform attribution.

The Commercial Integration Cell, which operates within the Combined Space Operations Center, could help integrate commercial capabilities into the attribution process.

Recommendations on the way forward

Incorporate space attribution into events and plans. DoD should incorporate a realistic and practical attribution process into space events such as senior leadership table top scenarios, along with space exercises and wargames like and the . U.S. planners should incorporate timely and realistic space attribution into associated campaign, operation, and contingency plans. Those within the NSDC should rehearse space attribution and determine any linkages with the U.S. , as applicable.

Increase SSA and forensic capabilities. DoD should develop and acquire robust SSA and forensics capabilities for not only kinetic events like anti-satellites weapons, but also non-kinetic events like lasing, jamming and network attacks. These collection capabilities and methods should be developed for the space, ground and user segments. DoD should investigate and better understand how to keep forensic data pristine, or uncorrupted, so that the validity of data and information is not called into question. Consequently, law enforcement involvement — such as from FBI and INTERPOL — may need to be integrated into space-centric events like exercises and wargames. This will help ensure that a chain of custody process is followed for evidentiary data, to support potential prosecution in a court of law.

Include allies and increase transparency. U.S. officials should consider the initiative as a framework for including allies in space attribution. Also, U.S. Space Command should look to include the space attribution process into , which is an international effort meant to strengthen deterrence in space and to prevent the spread of space debris. By including the global and numerous capabilities of allies and international partners, attributing the source or origin of an attack may be reached more quickly and with higher confidence. Including allies will lead to increased transparency and build confidence in the U.S. space attribution process.

Integrate the commercial sector. The existing digital forensics, jamming, and lasing data that are being collected every day by commercial companies will be helpful for informing attribution. More importantly, DoD should put in place service agreements for those commercial products and services needed to support a comprehensive, well-informed attribution process. At least initially, the should look to integrate the commercial sector’s attribution capabilities through the

In the years to come, the need for attribution in the space domain will only increase, especially as U.S. activities and interests expand toward and beyond. A belief that attributing hostile or malicious actions in space will be a simple process is wishful thinking. The means and methods of attributing action in the space domain must be debated, rehearsed and refined. Implementing the requisite means for space attribution will likely entail additional fiscal resources. The cost is low when compared to the disastrous effects caused from an event that a robust attribution process seeks to deter.

HELSINKI — A number of Chinese private launch firms for the burgeoning commercial space sector have reported progress in efforts to develop a range of launch vehicles.

Landspace and iSpace are reporting progress with methane rocket engines, while Galactic Energy is moving closer to launch of its Ceres-1 launcher. Deep Blue Aerospace has meanwhile secured early funding for development of a liquid launch vehicle series.

Landspace completed three gimbaling of the SkyLark (Tianque-12) 80t-thrust-level cryogenic methane and liquid oxygen rocket engine early-mid May. Tianque-11, a smaller, 10-ton liquid oxygen methane engine, passed 2,000 seconds of testing .

The engines will together power the 48.8-meter-tall, two-stage Zhuque-2 launch vehicle. The launcher will be capable of delivering a 4,000-kilogram payload capacity to a 200-kilometer low Earth orbit (LEO). Alternatively ZQ-2 can loft 2,000 kilograms to 500-kilometer Sun-synchronous orbit (SSO).

LandSpace’s lead engineer for propulsion technology states the Tianque-12 test success is the first verification test of the launcher’s engine system and control system compatibility, confirming the flight configuration of the engine for ZQ-2. The launcher now enters the joint compatibility test phase ahead of a first launch late 大庄家彩票平台 or early 2021.

Landspace was founded in 2015 and in October 2018 made the first private Chinese launch attempt with its Zhuque-1 solid rocket.

iSpace reusable launcher, VTVL tests

Beijing-based iSpace, which achieved orbit July 2019, also made progress with its own methalox engine in May.

The 15-ton thrust JD-1 engine completed a 200-second May 19. The engine passed a secondary start test May 27, paving the way for future vertical takeoff, vertical landing tests. JD-1 engines will power the reusable Hyperbola-2 methlox launcher, capable of lifting 1,900 kilograms to LEO.

The firm aims to conduct 100-kilometer vertical take-off and landing tests of the Hyperbola-2 first stage later this year. The full orbital test flight is planned for the first half of 2021. 

Vice president of iSpace Yao Bowen told following the SpaceX Demo-2 mission that “SpaceX is further along the track, but we share its vision of eventually sending passengers into space via cost-effective modules.”

Galactic Energy closes on Ceres-1 launch

Galactic Energy, established February 2018 and one of the newer Chinese private launch firms, has made progress toward its first launch. The four-stage Ceres-1 solid rocket will be able to lift 350 kilograms of payload to a 200-kilometer orbit.

The firm this week announced () that a successful payload fairing separation had been performed in May. A hot fire test of the upper stage attitude control engine took place in April, with a full system upper stage cold flow test following in May. 

was targeting a June launch of the Ceres-1 but the COVID-19 pandemic brought delays. Launch from Jiuquan is now expected in the August-September timeframe.

The firm secured $21.5 million in funding in December for the Ceres-1 launch and developing the Pallas-1 kerosene and liquid oxygen launch vehicle. The partially reusable Pallas-1 will be capable of launching four metric tons to LEO or two tons to SSO.

Deep Blue Aerospace seals funding

Beijing Deep Blue Aerospace Technology Co., Ltd., announced () Friday it had secured seed funding of more than $14.1 million (100 million yuan). The financing will be used for research and development, verifying vertical landing technology and testing kerosene-liquid oxygen engines.

Founded in 2017, Deep Blue Aerospace is developing the expendable Nebula-1 and recoverable Nebula-2 liquid launchers. The Nebula-1 first stage will be powered by nine Leiting-20 engines, with a single engine on the second stage.

The 2.25-meter-diameter Nebula-1 and 3.35-meter-diameter Nebula-2 are to be capable of lifting 500 kilograms to 500 km SSO and 4,500 kilograms to LEO respectively. No date for test flights was provided.

China大庄家彩票平台 opened segments of the space sector to private capital in 2014. More than 141 registered commercial aerospace companies, developing launch vehicles, small satellite platforms, remote sensing and communications satellite constellations, ground stations and various parts of supply chains had been established in China大庄家彩票平台 at the end of 2018, according to Chinese publication Future Aerospace.  

China大庄家彩票平台’s National Development and Reform Commission added ‘satellite internet’ to a list of “new infrastructures” in an April meeting. Satellite internet, 5G, Internet of Things and artificial intelligence, to be targeted for investment and guidance. The move is perceived as an attempt to boost innovation in the technology sector and stimulate the Chinese economy. 

A military-civil fusion national strategy is supporting and facilitating these commercial space activities. The aim is to foster innovation in military and civilian realms but also develop new supply chains and lower costs.

大庄家彩票平台Trump ad

WASHINGTON — The reelection campaign of President Donald Trump has taken down an online ad tied to the recent Demo-2 commercial crew launch after complaints it appeared to violate NASA media guidelines, and criticism from one person who appeared in it.

The ad, titled , was posted on YouTube June 3 by the Trump campaign. Running about two and a half minutes, the ad featured a mix of historical footage, such as from the Apollo program, along with video from the May 30 launch of SpaceX’s Demo-2 commercial crew mission.

Trump attended that launch, and .

“Once more, we will launch intrepid souls blazing through the sky and soaring into the heavens,” Trump said in a snippet of that 2018 speech played in the ad. “Once more, we will summon the American spirit to tame the next great American frontier.”

The ad makes extensive use of NASA and SpaceX video from the Demo-2 launch, including closeups of the mission’s crew, NASA astronauts Bob Behnken and Doug Hurley. Many SpaceX employees, as well as company founder Elon Musk, appear in the video snippets included in the ad.

While NASA makes its images and video widely available, as does SpaceX on many occasions, the prominence of the astronauts in the video appears to be in violation of .

“Current NASA employees, including astronauts, may not appear in commercial material,” those guidelines state. “If a recognizable person, or talent (e.g., an astronaut or a noted personality engaged to narrate a film) appears in NASA material, use for commercial purposes may infringe a right of privacy or publicity. Permission should be obtained from the recognizable person or talent if the proposed use of the NASA material could be viewed as a commercial exploitation of that person.”

One person who appeared in the ad objected to it. “I find it disturbing that a video image of me and my son is being used in political propaganda without my knowledge or consent. That is wrong,” tweeted Karen Nyberg, a former astronaut who is married to Demo-2 astronaut Doug Hurley. She appears briefly in NASA footage of them wishing Hurley farewell as he and Behnken head to the launch pad.

Less than two hours after Nyberg’s tweet, the video had been removed from YouTube, apparently by the Trump campaign. “This video has been removed by the uploader,” a YouTube error message states. The Trump campaign did not immediately respond to an email with questions about the video.

Sources within both NASA and SpaceX, speaking on background, said they were not aware of the ad until after the campaign published it on YouTube. In its brief time online, it generated only a little more than 25,000 views, a small fraction of the traffic that popular videos on the site normally generate.

The video also prompted calling for its removal. That petition criticized the perception created by the ad that the commercial crew program was an initiative of the Trump administration. It noted that the program formally began during the Obama administration and built upon earlier projects by the Bush administration.

“The implication that any one person was responsible for the SpaceX-NASA Crew Demo-2 launch is an insult to the work of the teams that meaningfully contributed to its success,” stated the petition, which had nearly 4,500 signatories by the time the campaign removed the ad.

Others criticized it for a minor but embarrassing gaffe. In the opening frames of the ad, part of what appears to be a spacesuited astronaut appears on the screen. On the suit, partially obscured but still recognizable, is the logo not of NASA but of the European Space Agency.

A June 4 letter to the FCC suggests senators are concerned that the backlash to the Ligado ruling has dominated the narrative.

大庄家彩票平台

WASHINGTON — A bipartisan group of senators asked Federal Communications Commission Chairman Ajit Pai in a June 4 letter to provide a detailed account of how the agency arrived at the Ligado’s use of a portion of the L-band spectrum to build a 5G wireless network.

The FCC’s April 20 ruling drew and other government agencies that claim Ligado’s network will interfere with the Global Positioning System that also operates in the L-band spectrum. These agencies have filed a petition to .

The June 4 letter was signed by eight senators, most of them members of the Committee on Commerce, Science, and Transportation that oversees the FCC. The letter asks Pai to answer a list of 13 questions related to the Ligado decision and to “explain why the FCC believes granting this application is in the public interest.”

The letter suggests senators on the Commerce Committee are concerned that the negative reactions from the Pentagon and from the Senate and House Armed 大庄家彩票平台 Committee have dominated the narrative and that the FCC has not told its side of the story.

The Senate Armed 大庄家彩票平台 Committee held a hearing on May 6 where DoD officials voiced their strong opposition to the FCC’s order but nobody from the FCC was invited to testify. On May 21 the House Armed 大庄家彩票平台 Committee held a private conference call with FCC officials to discuss the matter.

“Congress has entrusted the FCC to make important technical and data-driven decisions regarding spectrum allocation and interference,” the letter says.

“We appreciate that SASC considered the Department of Defense’s position on the use of this spectrum but SASC only heard testimony in opposition to the modification of Ligado’s license.”

The Commerce Committee has been an advocate of the commercial use of spectrum and of the FCC’s role overseeing the private sector’s use of spectrum.

“America’s spectrum policies must promote the efficient use of spectrum in order for the United States to maintain its global leadership in wireless deployments and innovation,” says the letter.

The letter was signed by Sens. Mike Lee (R-Utah), Brian Schatz (D-Hawaii), Ron Johnson (R-Wisc.), Edward Markey (D-Mass.), Ted Cruz (R-Texas), Mark Warner (D-Va.), John Thune (R-S.D) and Chris Coons (D-Del.).

Felt said NASA’s commercial crew program is “super exciting” and one that the Space Force can learn from.

WASHINGTON — The U.S. Space Force will be far smaller than the other military services but way more dependent on technology to do its job. While the Space Force will develop satellites and other technologies in-house, it also plans to follow the NASA playbook and team up with the private sector, said Col. Eric Felt, head of the Air Force Research Laboratory’s Space Vehicles Directorate.

Speaking at a SpaceNews online event June 4, Felt said NASA’s commercial crew program is “super exciting” and one that the Space Force can learn from.

The launch of a SpaceX Crew Dragon capsule on May 30 that took NASA astronauts to the International Space Station was the “culmination of perhaps the most successful private-public partnership of all times,” said Felt.

The Space Vehicles Directorate, located at Kirtland Air Force Base, New Mexico, is one of the organizations that Air Force Secretary Barbara Barrett agreed to Felt said his office will remain at its current location but approximately 700 people will be reassigned to the Space Force

“The Space Force is going to be the most high tech of all of the services,” said Felt.

Public-private partnerships like NASA’s commercial crew deals with SpaceX and Boeing have saved NASA billions of dollars and serve as a “powerful model” that the Defense Department could adopt, said Felt.

AFRL is applying the model albeit on a smaller scale, Felt said.

There are many commercial capabilities that can be used to meet military needs, he said. For space systems one way to do that is with a “hybrid architecture.” AFRL, for example, is conducting an experiment integrating data from 266 commercial remote sensing satellites with dedicated national satellites “to create a capability that’s much more robust and resilient than just any one piece of that all by itself.”

Another area suitable for public-private deals are data services to help the Space Force monitor every object in outer space, a discipline the U.S. military calls “space domain awareness.”

He noted that commercial companies now have systems to track and investigate space objects.

AFRL, the Defense Innovation Unit and the Space Force’s Space and Missile Systems Center have been talking about setting up a “space commodities exchange,” for example, where space services could be traded like commodities, said Felt.

“It opens up the financial engine to optimize the price and the quality, where you establish certain quality standards for what you’re going to need,” he said. “The space domain awareness data might be a great example of the kinds of things that the Space Force could purchase through a space commodities exchange.”

The space commodities exchange is “one of the experimental business models that we’re working towards in the public private partnership area,” said Felt.

Opportunities with LEO constellations

Companies that are deploying broadband constellations in low Earth orbit also would be candidates for partnerships where satellites would host government communications payloads, he said.

AFRL next spring will launch an experimental cubesat equipped with a Link 16 encrypted radio frequency data link widely used on U.S. military and NATO aircraft and ground vehicles to share information

The Link 16 cubesat would serve as a communications network relay in space.

“This is something we’ve never been able to do before because our traditional communication satellites up in GEO [geostationary orbits] are too far away,” said Felt. “But if we have a proliferated LEO constellation then what we could do is put one of these Link 16 transponders onto each of these LEO satellites and you would basically have a Link 16 capability everywhere all the time.”

If the Link 16 experiment is successful, said Felt, “that’s a great opportunity for us to partner with these commercial companies that are putting up proliferated LEO constellations.” He said there are about 30,000 Link 16 radios across the U.S. military and NATO so “it would be super powerful to be able to have that kind of a transponder available everywhere because the signals can’t go through mountains. It’s a great capability to do from space.”

Another opportunity to work with LEO satellite operators is for the deployment of sensors for the Air Force . The program is looking at alternative platforms to integrate and analyze data during military operations.

The data collection and processing is currently done aboard large command-and-control airplanes that would be vulnerable flying over enemy territory, said Felt. “Those are ideal missions to also move to low Earth orbit and leverage some of the commercial capabilities that are out there.”

大庄家彩票平台

WASHINGTON — Astronomers who have spent the last year worried about the effect that SpaceX’s Starlink satellites will have on their observations say they are increasingly concerned about the impact from other proposed megaconstellations.

Astronomers became alarmed about the effect the Starlink satellites would have after the launch of the initial set of 60 spacecraft in May 2019. Since then, an American Astronomical Society (AAS) committee has been working with the company to discuss ways to mitigate the effect the satellites would have on astronomy.

SpaceX has responded to those concerns first with an experimental “DarkSat” launched in January, whose surfaces were darkened to reduce the amount of sunlight they reflected. SpaceX followed that up with a “VisorSat” on the most recent Starlink launch June 3, a satellite that has sunshades intended to block sunlight from reaching reflective surfaces on the satellite.

While the effectiveness of VisorSat will have to be measured in the weeks ahead once the spacecraft reaches its final orbit, astronomers say they’re pleased that SpaceX has been willing to work with them on the issue. “The bottom line is that significant resources at SpaceX are being devoted to these technical solutions,” said James Lowenthal of Smith College during a press conference at the 236th Meeting of the AAS June 3.

SpaceX, however, is not the only company with satellite megaconstellation plans. Lowenthal said that astronomers have had far fewer discussions with other satellite operators. “We had one telecon with OneWeb, but then they declared bankruptcy,” he said during a presentation at the conference June 2. “We’ve had no major conversations with other operators.”

That lack of discussions is magnified by new proposals by some companies, including OneWeb, to expand their constellations. Despite filing for Chapter 11 bankruptcy in March, OneWeb submitted plans with the Federal Communications Commission May 27 to increase its constellation by 48,000 satellites to give it “greater flexibility to meet soaring global connectivity demands,” according to a company statement about the proposal.

“The situation just got worse,” said Pat Seitzer of the University of Michigan, who has been studying the effect of Starlink and other satellite constellations on astronomy, at the AAS press conference. The filings by OneWeb and other companies would add as many as 50,000 satellites on top of plans for systems that proposed up to 60,000 satellites. “That’s a very serious problem.”

The OneWeb proposal would put its satellites into orbits about 1,200 kilometers high, far higher than the Starlink satellites at 550 kilometers. At that higher altitude, he said, the satellites would be visible for longer after sunset and before sunrise. In one scenario examining conditions at the Vera Rubin Observatory under construction in Chile, at least 500 satellites would be visible at any given time all night long in the summer.

At the higher altitude, the satellites will be too dim to be seen with the naked eye, assuming the new constellation uses a design similar to OneWeb’s existing satellites. However, Seitzer said that they would still be bright enough to saturate sensitive instruments at that observatory, interfering with observations.

Other observatories are worried about the new constellations as well. Lowenthal said at the briefing that the AAS surveyed 23 observatories around the world about the impacts of satellite megaconstellations, starting with the effects of an initial set of 1,584 Starlink satellites.

“The majority of the observatories responding expressed significant concerns, grave challenges to science and predicted significant financial costs,” he said. The affected research, he said, included wide-field surveys where it’s impossible to avoid satellites passing through the field of view as well as time-sensitive observations of transient phenomena.

Asked to assess the effects if there are 20,000 satellites in orbit from various megaconstellations, he said, a majority said that nearly all their observations would be affected. “About half said there would be a critical failure of that facility.”

AAS is holding an online workshop in late June to discuss the issue with astronomers and satellite companies. Besides SpaceX, Lowenthal said that Amazon, which is developing a satellite system called Project Kuiper, planned to participate.

“Will all these companies be good citizens? We don’t know,” he said of those proposing megaconstellations, warning that such systems threaten to “draw the blinds” on the night sky. “Astronomers are working hard with SpaceX and, we hope, other satellite operators to understand and to reduce the impacts to astronomy and the night sky.”

The Air Force Research Laboratory’s Space Vehicles Directorate in New Mexico is one of 23 space-related organizations set to transfer to the U.S. Space Force under plans unveiled last month. 

As the Department of the Air Force’s “Center of Excellence” for space technology R&D, the Space Vehicles Directorate develops, demonstrates and transitions critical technologies for the entire gamut of military space missions, including communications; positioning, navigation and timing, missile warning, space situational awareness, and defensive space control.

Col. Eric Felt, the Air Force officer who leads the Space Vehicles Directorate and its team of 1,000 military, civilian, and on-site contractors, talks with SpaceNews Staff Writer Sandra Erwin and Editor-in-Chief Brian Berger about the R&D  investments the directorate is making to help the U.S. military maintain a technological advantage in the space domain.

  • How can the U.S build more resilient space technology in the face of anti-satellite threats?
  • What is the role of the private sector in bringing innovation into military programs? 
  • How does the standup of the U.S. Space Force change the thinking about R&D investments? 

Also joining the conversation is Paul Jaffe, a U.S. Naval Research Laboratory engineer and principal investigator for a space-based solar power experiment flying on the X-37B autonomous spaceplane the Space Force launched May 17.

Jaffe discusses the experiment and what it could mean for future capabilities to harvest power from space.

Three months after the coronavirus pandemic brought large swaths of the global economy to a near halt, Asia-Pacific satellite operators say they are still trying to identify a new normal.

大庄家彩票平台

WASHINGTON — Three months after the coronavirus pandemic brought large swaths of the global economy to a near halt, Asia-Pacific satellite operators say they are still trying to identify a new normal. 

The most immediate impact for communications satellite operators has been a potentially long downturn in air and maritime transportation that’s resulted in a drop in broadband demand from those sectors. Other impacts from a global pandemic that’s decimated some businesses while sparing others are less obvious, however. 

“There are opposing forces on the market that we observe,” Christian Patouraux, chief executive of Kacific, said during a June 2 webinar hosted by the Asia-Pacific Satellite Communications Council. 

Demand for broadband internet is “through the roof” as people work from 大庄家彩票平台 and spend free time indoors, he said. But some Kacific customers, such as those whose income is dependent on the Asia-Pacific’s tourism industry, are struggling to pay bills, he said. 

“They have cash problems, they don’t see the future as being very bright for the next year, the next two years — potentially more — depending on how deep this will affect the economy,” Patouraux said.

Kacific-1, the Singapore-based company’s first satellite, concentrates coverage on Asia-Pacific island nations and archipelagos including Indonesia, the Philippines and Vanuatu where the tourism industry is a major employer. 

Nile Suwansiri, the chief commercial officer of Thailand-based Thaicom, said television viewership has surged during the pandemic, which would normally be a positive development, but many of Thaicom’s broadcast customers are “free-to-air,” meaning they are dependent on ads to support their channels. 

“Viewing time is up, but the pool of advertising revenues have gone down significantly,” Suwansiri said. 

Making matters worse, advertisers who would normally book television commercials are increasingly switching to online ads to lure house-bound customers through e-commerce offers, he said. 

“Our customers have seen an impact on lost revenues, which basically dominos to the satellite operator and to their ability to make payments,” Suwansiri said. 

Broadband demand is up, he said, not only for entertainment but also remote education, a service Suwansiri said is likely to remain popular well after the pandemic. 

Huang Baozhong, APT Satellite executive vice president, said that with the exception of maritime, aviation, and oil, most markets the Hong Kong-based company serves are continuing without difficulty. Some customers have asked to defer payments while stay-at-大庄家彩票平台 orders and other restrictions put a damper on their earnings, he said. 

“Most of our customers, they are still honoring their contracts, but only ask for some support,” he said. One customer Baozhong did not name is seeking to renegotiate a contract, an effort he said could result in a longer contract in exchange for lower pricing during the pandemic. 

Satellite operators said they are watching government coronavirus-relief spending for opportunities for the satellite sector. Baozhong and Patouraux said some Asia-Pacific governments looking at infrastructure spending to revive flagging economies are largely overlooking satellites. Suwansiri, however, said Thaicom sees projects emerging focused on digital economies, which should ultimately benefit the satellite industry. 

“All industries are affected by COVID, but I think we should be quite fortunate that we are in the infrastructure side of things,” he said. “I wouldn’t want to be in the automotive or tourism industry at the moment.”

SAN FRANCISCO – Silicon Valley startup Momentus announced a contract June 4 with OrbAstro, a small United Kingdom company developing hardware and software to enable satellites to operate in flocks or constellations.

Under the contract, Momentus, a firm developing in-space transportation services, will fly a three-unit OrbAstro cubesat on a SpaceX Falcon 9 dedicated rideshare mission scheduled for launch in 2021. Momentus plans to enclose the OrbAstro cubesat in its Vigoride orbit transfer vehicle for the Falcon 9 launch. At the conclusion of the Falcon 9 flight, Vigoride will transport the OrbAstro cubesat to a higher altitude.

Through the mission, OrbAstro plans to demonstrate a variety of technologies including an UltraScale+ high-performance computer coupled with a constellation management system based on an artificial neural network, a novel electrical power system, a compact attitude determination and control system, and a new thermal management system.

After the in-orbit demonstration, OrbAstro plans to launch its own cluster of formation flying nanosatellites to test remaining technologies the firm is developing, before focusing on the needs of larger constellations, Ash Dove-Jay, OrbAstro founder and CEO, said in a statement.

Momentus, based in Santa Clara, California, plans to conduct the first test flight this year of its Vigoride orbit transfer vehicle.

“We are excited to see OrbAstro working on developing key technologies that could really enable flocks of satellites to be in close proximity of each other,” Momentus CEO Mikhail Kokorich said in a statement. “In the future, this [technology] may enable Momentus to do rendezvous and proximity operations for refueling, satellite servicing, repositioning and more.”

Raytheon won a National Oceanic and Atmospheric Administration contract for a design study of Real Time Imager, an instrument to obtain high-resolution Earth observation imagery from geostationary orbit.

大庄家彩票平台

SAN FRANCISCO – Raytheon won a National Oceanic and Atmospheric Administration contract for a design study of Real Time Imager (RTI), an instrument to obtain high-resolution Earth observation imagery from geostationary orbit.

NOAA awarded Raytheon Intelligence & Space a $413,088 contract in April to spend six months assessing an approach called step-and-stare imaging.

Unlike the Advanced Baseline Imager on NOAA’s Geostationary Operational Environmental Satellite-R (GOES-R) series, which captures imagery by continually scanning scenes, RTI is designed to stare at an area larger than 1,000 kilometers by 1,000 kilometers before focusing on another area. The next areas of focus can be adjacent to the previous one or across the globe.

“By staring we get much better sensitivity,” Jeff Puschell, Space Systems principal engineering fellow for Raytheon Intelligence & Space, told SpaceNews. “With our rather large footprint, we cover the entire Earth very efficiently.”

The Raytheon award is one of a series of contracts NOAA is issuing to investigate potential instruments, spacecraft, business models and mission concepts for the space-based architecture to succeed the Joint Polar Satellite System and GOES-R series.

As of June 2, NOAA had awarded 26 contracts for analyses of instrument and mission concepts. Fourteen of the contracts fund studies related to geostationary and extended orbits. Another 12 fund studies focused on low Earth orbit sounding.

Raytheon is assessing various approaches to RTI, including evaluating the merits of cooled and uncooled infrared detectors.

“One advantage of a step-and-stare architecture is its efficiency,” Puschell said. “We can cover the earth quickly with uncooled infrared technology based on microbolometers.” (Microbolometers are devices used to measure electromagnetic radiation.)

For the NOAA study, Raytheon draws on a microbolometer array the firm developed and space-qualified for the Europa Thermal Emission Imaging System, which the company is producing for the Europa Clipper mission. The uncooled instrument could meet “almost all of the objective level requirements” for a new imager in addition to a day-night band, Puschell said, adding the technology would significantly reduce spacecraft power consumption.

Raytheon also is touting RTI’s speed in gathering and downlinking data.

“We transmit the data from the previous stare during the current stare,” Puschell said. “We start collecting data on the next location while we’re transmitting the data we’ve already collected. That gives us relatively short latency.”

The exact latency will depend on RTI’s spectral band combination and downlink speeds. RTI “can have up to 32 spectral bands and as few as four,” Puschell said. “NOAA is asking us to look at how latency varies with the number of spectral bands.”

In addition to the Europa mission, RTI draws on technology Raytheon developed for the Joint Polar Satellite System Visible Infrared Imaging Radiometer Suite (VIIRS).

“The spectral bands that we use in RTI are very similar to VIIRS, including the day-night band,” Puschell said. However, Raytheon updated the technology because NOAA is demanding higher spatial resolution for its next-generation geostationary imaging instrument.

SpaceX launched a batch of 60 Starlink broadband satellites June 3, including one with a deployable sunshield meant to test out a new way to reduce the brightness of future satellites.

大庄家彩票平台

WASHINGTON — SpaceX launched a batch of 60 Starlink broadband satellites June 3, including one with a deployable sunshield meant to test out a new way to reduce the brightness of future satellites. 

The Falcon 9 rocket lifted off at 9:25 p.m. Eastern from Cape Canaveral Air Force Station in Florida, and deployed the satellites into low Earth orbit 15 minutes later. 

The rocket’s first stage landed on SpaceX’s drone ship “Just Read the Instructions” about nine minutes after lift off. The launch marked the fifth use of that booster, which previously flew one mission to geostationary transfer orbit and three missions to low Earth orbit, the latest being in January, also for Starlink. The launch was also the first time SpaceX successfully recovered a first-stage booster after five flights. 

SpaceX has launched 482 Starlink satellites, counting Wednesday’s launch and two prototypes launched in 2018. The company had planned its latest Starlink mission for May, but was delayed by Tropical Storm Arthur until after the company’s Demo-2 Crew Dragon mission to the International Space Station, which took place May 30

May was the first month this year SpaceX did not conduct a Starlink launch. The company had averaged one Starlink launch a month before the delay. SpaceX was originally targeting two Starlink launches a month throughout 大庄家彩票平台.

SpaceX is building and launching a constellation of up to 12,000, and potentially 42,000 satellites in low Earth orbit to support a global satellite internet service. The company expects to start service late this year in Canada and parts of the United States. 

SpaceX plans to add deployable visors to all future Starlink satellites after launching around 500 with their current design, Patricia Cooper, SpaceX’s vice president of satellite government relations, said during a webinar last week. 

“We would have about 500 satellites at their current brightness, and then all satellites beyond that would have these sunshades,” Cooper said during a webinar hosted by the American Astronomical Society and the Satellite Industry Association. “That is the ratio we would be looking at.”

SpaceX is seeking to lessen the brightness of Starlink satellites to reduce their impact on astronomy.

A NASA airborne astronomy observatory that has been grounded for nearly three months by the coronavirus pandemic may resume flights later this month as advocates for the program address another cancellation threat.

大庄家彩票平台

Updated June 4 with additional NASA comment on SOFIA return to flight plans.

WASHINGTON — A NASA airborne astronomy observatory that has been grounded for nearly three months by the coronavirus pandemic may resume flights later this month as advocates for the program address another cancellation threat.

The Stratospheric Observatory for Infrared Astronomy (SOFIA), a Boeing 747SP with a 2.5-meter infrared telescope, halted flight operations March 19 because of the coronavirus pandemic. NASA cited needs “to ensure the safety of all staff and to comply with state and local county orders” where the plane is based, the Armstrong Flight Research Center in California, as the reasons for halting operations.

Margaret Meixner, director of SOFIA science mission operations at the Universities Space Research Association (USRA), which manages SOFIA program science, said June 2 that efforts are underway to resume flight operations soon. That includes a “mandatory maintenance period” for the aircraft itself as well as checking out its instruments.

“The current plan is to return to SOFIA flights in late June,” she said in a presentation at the 236th Meeting of the American Astronomical Society, held online. Those will start with test flights using one instrument, an infrared camera called HAWC+.

Paul Hertz, director of NASA’s astrophysics division, also discussed plans to resume SOFIA operations at a NASA town all event during the conference June 1. “The SOFIA team is trying to develop a plan that would allow us to conduct science operations, but still maintain best practices for keeping the staff safe during the pandemic,” he said.

NASA spokesperson Felicia Chou said June 4 that the plans are being developed by the overall SOFIA team, including USRA as well as NASA’s Armstrong Flight Research Center and Ames Research Center, which hosts the SOFIA program office. She said the plans are still being developed with the hope of finalizing them in the “next few weeks.”

A return to flight in late June, Meixner said, would allow SOFIA to proceed with plans for a “deployment” to the southern hemisphere, where the aircraft flies to New Zealand to carry out a series of science flights there for observing celestial bodies not visible in the northern hemisphere. That deployment is scheduled for mid-August to mid-September, she said, using the GREAT spectrometer.

The grounding of SOFIA meant that some planned observations could not be performed. Meixner said observations designated “priority one,” as well as “priority two” programs that had started but had not yet been completed at the time SOFIA was grounded, will be carried over to future observing cycles.

The grounding comes at a particularly bad time for SOFIA, which is facing the threat of cancellation. NASA’s fiscal year 2021 budget proposal included no funding for SOFIA, which received $85.2 million in the final fiscal year 大庄家彩票平台 appropriations bill.

NASA said that SOFIA’s high cost — only the Hubble Space Telescope has a higher annual budget among operational astrophysics missions — could not be justified by a science output “not on par with other large science missions,” according to the agency’s budget proposal. “Dramatic improvement in SOFIA’s scientific productivity is not expected.”

NASA, which had been directed by Congress not to include SOFIA in its senior review of astrophysics missions, instead performed reviews of SOFIA science and mission operations in 2019, resulting in a number of recommendations. They included doing a larger number of flights that last 8 hours instead of 10, which reduces the amount of fuel the plane carries. That, in turn, allows it to spend more time in the stratosphere, where it conducts science observations above most of the atmospheric water vapor that absorbs infrared light.

Hertz, in the town hall meeting, praised SOFIA for its work implementing those recommendations. “I’m really pleased with the way the SOFIA project has taken a hold of this challenge and has gone after it in a big way,” he said. Those changes, he said, “are directed at improving the amount of impactful science that SOFIA does.”

Meixner said she’s hopeful that Congress will reject the proposed cancellation when it takes up appropriations bills to fund the agency, a process expected to begin later this month. She referenced an earlier attempt by NASA, in 2014, to cancel SOFIA that was blocked by Congress.

“We’re working full throttle to support SOFIA now,” she said. “We are hoping, as they’ve done in the past, to put SOFIA back into the budget. It’s really Congress that makes the call on those things, not the president.”

Data received so far from space industry suppliers shows the pandemic has caused schedule delays and strains on the supply chain.

大庄家彩票平台

WASHINGTON — The Pentagon’s Space Acquisition Council is reviewing early results of a survey of space industry suppliers that asked companies to identify specific impacts of the coronavirus crisis on their businesses.

Deputy Assistant Secretary of Defense for Space Policy Stephen Kitay, who is a member of the council, said the data received so far reveals widespread consequences of the pandemic.

“We’re reviewing the results as they come in,” Kitay said on a hosted by the American Institute of Aeronautics and Astronautics.

“I’m not going to go into all the details,” said Kitay. But he did identify some broad areas of concern. “We are seeing reports of schedule impacts, strain on supply chains and adjustment to future business plans.”

The survey was sent to companies last month by the Space Enterprise Consortium, a procurement organization under the Space Force’s Space and Missile Systems Center that works with both traditional defense contractors and commercial vendors.

Kitay said there is agreement in the space council that during this downturn DoD has to keep projects moving to help the industrial base.

“We have to keep the mission going,” he said. “And this includes the space industrial base that we rely on. Sustaining the space industrial base is a national security concern.”

The Space Acquisition Council, led by Assistant Secretary of the Air Force for Acquisition Will Roper, includes senior leaders from DoD and the intelligence community.

“We continue to make contract awards, and in some cases have accelerated those awards,” Kitay said. DoD also has waived cost penalties to contractors for schedule delays.

“We have to keep the work going,” said Kitay. “We have to keep the opportunities, and in particular competitive opportunities in this environment.”

To encourage small businesses and startups compete for contracts during the pandemic, Kitay said, the Space and Missile Systems Center and the are conducting virtual meetings to hear pitches from companies.

“This is where innovative companies can pitch, submit ideas that will be evaluated and then connected into the Small Business Innovation Research program,” he said. “Small businesses and startups can offer disruptive and sometimes game changing ideas and technologies.”

GAO in its annual assessment of DoD acquisition programs says Next-Gen OPIR “faces multiple challenges."

]]>
大庄家彩票平台

WASHINGTON — U.S. Space Force plans to deploy five missile-warning satellites by 2029 so far is progressing on schedule but the service might be underestimating risks in the program, the Government Accountability Office

The program known as Next-Generation Overhead Persistent Infrared Block 0, or Next-Gen OPIR, was started by the U.S. Air Force in 2018 to supplement existing missile defense satellites. The Air Force compressed the program schedule by 42 months and plans to launch the first satellite by 2025. Next-Gen OPIR is now managed by the U.S. Space Force.

GAO in its annual assessment of DoD acquisition programs says Next-Gen OPIR “faces multiple challenges.” The report identifies two main issues. One is that a $2 billion ground system being developed for Next-Gen OPIR might not be ready when the first satellite goes to orbit. Another concern is that the integration of the sensors with the spacecraft will be more complex than anticipated.

In the annual report released June 3, GAO included “rapid prototyping and rapid fielding programs” in response to a provision in the National Defense Authorization Act for Fiscal Year 2019. The Next-Gen OPIR Block 0 falls in that category of “rapid prototyping” programs.

The constellation consists of three geosynchronous Earth orbit (GEO) satellites made by Lockheed Martin and two polar coverage highly elliptical orbit satellites made by Northrop Grumman.

GAO says one of the risks in Next-Gen OPIR is that the ground system “may not be ready when the first GEO satellite is delivered.” The Air Force in late 2019 selected Raytheon to develop an open-architecture operating system for future Next-Gen OPIR ground stations but a contract has not yet been awarded.

To ensure a ground system is available for the first launch, the program is designing GEO satellites to integrate into the ground architecture of existing Space Based Infrared System satellites but GAO says that will require “some modifications.”

The estimated $11 billion Next-Gen OPIR system is being built with existing satellite buses and sensor technology to reduce the risk, GAO says, but the program could run into difficulties in the integration phase. “While the program considers the spacecraft a mature legacy technology, the spacecraft will be modified to meet new mission requirements,” says the report. “DoD officials acknowledged the added risk presented by the first-time integration of a new sensor design with a modified spacecraft.”

Next-Gen OPIR is scheduled for a “critical design review” in November 2021. According to the report, Space Force officials told GAO that the program “is leveraging existing technology to mitigate multiple risks.”

NASA and Northrop Grumman are increasing work on the James Webb Space Telescope that slowed during the coronavirus pandemic, but the agency has yet to confirm a new launch date for the mission.

大庄家彩票平台JWST stowed

WASHINGTON — NASA and Northrop Grumman are increasing work on the James Webb Space Telescope that slowed during the coronavirus pandemic, but the agency has yet to confirm a new launch date for the mission.

Integration and testing, or I&T, of JWST was in progress at a Northrop Grumman facility in Southern California when NASA decided in mid-March to have personnel assigned to oversee that work return 大庄家彩票平台. While agency officials originally said that would effectively stop work on the flagship space telescope, activity has instead continued at a low level since then, including stowing the telescope in its launch configuration ahead of another round of vibration and acoustics tests.

Paul Hertz, director of NASA’s astrophysics division, said NASA personnel returned to the Northrop Grumman facility last week. Appearing at a June 1 NASA town hall event that was part of the 236th Meeting of the American Astronomical Society (AAS), held online, he said that Northrop Grumman was planning to resume a second daily shift of work on the telescope that had been suspended during the pandemic.

Jonathan Gardner, deputy senior project scientist for JWST at NASA’s Goddard Space Flight Center, said during a separate presentation about the mission during the AAS conference June 2 that, before the pandemic, Northrop was running 12 shifts a week of 10 hours each. During the pandemic, the company had just five shifts a week of eight hours each.

“We will be gradually ramping up the NASA presence and the number of shifts,” he said. That will support a comprehensive system test of the telescope and a pre-environmental review before the final set of vibration and acoustics tests. After that, the telescope will go through a final set of deployment tests of its major structures, including its large sunshield, before being stowed in its launch configuration again for shipment to the launch site.

Before work on JWST slowed down in March because of the pandemic, the mission was on schedule for a launch in March 2021, with 52 days of schedule reserve remaining. The amount of schedule reserve, though, led some to question if the mission could make that launch date. A Government Accountability Office report in January warned a launch next March “may not be feasible” given the amount of work remaining and the rate at which the project was using up schedule reserves.

NASA has not yet formally changed the JWST launch date. “We will have to evaluate the schedule and reassess what the most likely launch date is,” Hertz said. “At the moment, we’re still working towards the currently announced launch date.”

Hertz didn’t say when that schedule reassessment would take place. In January, NASA officials said that they planned to review and, if necessary, update the launch date during a review before the final set of environmental tests. At the time, that review was scheduled for May.

Gardner acknowledged that some kind of delay to the March 2021 date is likely. “We’re expecting a delay,” he said. “NASA is working through the process of determining what the schedule will be as we start to ramp back up on the I&T activities. We’ll take a hard look at that.”

The pandemic has affected other aspects of the mission as well. The Space Telescope Science Institute, which will manage science operations of JWST, released a call for proposals for a first round of observations, called Cycle 1, in January. At the time, proposals were due on May 1.

The institute, though, has delayed the due date for those Cycle 1 proposals, citing the pandemic. In a June 1 update, it announced that it has not set a new deadline for proposals, and won’t set one before mid to late July. The institute added it will provide at least 12 weeks’ notice of a revised deadline for proposals.

“What is at the top of our minds is the state of our community and the challenges they have been facing with this pandemic, so it was not tenable to keep the deadline as it was,” said Klaus Pontoppidan, JWST project scientist at the institute, during a June 2 presentation at the AAS meeting. He added that proposals can continue to be submitted and updated as the institute reevaluates the Cycle 1 schedule.

Astroscale is acquiring the rights to Effective Space Solutions' satellite servicing vehicle known as Space Drone.

]]>
大庄家彩票平台

WASHINGTON — Astroscale announced June 3 it is acquiring the intellectual property of the satellite-servicing company Effective Space Solutions. The move positions Astroscale’s U.S. subsidiary to become a direct competitor to Northrop Grumman in the geostationary satellite servicing market.

Astroscale is a private orbital headquartered in Tokyo. The agreement with Effective Space Solutions was signed by Astroscale U.S. Inc., based in Denver.

Effective Space Solutions, located in Israel, developed a satellite servicing vehicle known as Space Drone which is not yet in operation. Astroscale is acquiring the intellectual property associated with Space Drone and is hiring engineers and executives from the program.

Arie Halsband, founder and CEO of Effective Space Solutions, will serve as managing director of Astroscale Israel in Tel Aviv.

The Space Drone will evolve into an Astroscale servicing platform, Ron Lopez, president and managing director of Astroscale U.S., told SpaceNews.

“It will be a new program and will be called something else,” he said. “We will integrate the payload in the United States and deliver that service from the U.S.”

Effective Space Solutions has been in discussions with potential undisclosed customers for Space Drone services. Astroscale has had “preliminary meetings with those customers and they remain interested,” said Lopez.

The closing of the transaction is subject to customary regulatory approvals.

Lopez said Astroscale is on a path to become a provider of on-orbit services from low Earth to geostationary orbits.

Astroscale later this year plans to launch a self-funded mission to low Earth orbit — called End-of-Life Service by Astroscale Demonstration (ELSA-D) — to test debris removal technologies. The company in February was selected as the for a project to develop an inspector satellite to identify upper stage rocket bodies.

Market analysts project that life extension and other on-orbit satellite services will generate more than $4 billion in revenues by 2028. With GEO satellites costing upwards of $200 million, the thinking is that servicing, repairing or upgrading them will become a viable option instead of replacement.

Ahead of entering the GEO satellite servicing market, Astroscale Holdings on round. I-NET CORP., a Japanese data center provider, became the first investor in this new round. Astroscale raised a total of $140 million in its previous four funding rounds.

Astroscale’s GEO servicing platform would compete with (MEV).

Lopez said the MEV is “blazing new trails” and that that there is room in the market for additional players. “We see strong commercial and U.S. government demand,” he said.

The U.S. Defense Department could be a future buyer of services, he said. “We have heard they are interested in exploring the idea of extending the service life of its GEO satellites. When you’re faced with tough budgetary decisions, I think it only makes sense to entertain these kinds of tradeoffs.”

CBO estimates that standing up a Space National Guard would cost about $100 million a year.

]]>
大庄家彩票平台

WASHINGTON — A by the Congressional Budget Office estimates that standing up a Space National Guard as a reserve component of the U.S. Space Force would cost the Pentagon about $100 million a year.

The CBO estimate released on June 2 contradicts arguments made by the National Guard Bureau that if a Space National Guard were established, it would not create additional costs because people and other resources would be transferred from existing organizations.

The cost of a Space National Guard is one of the concerns being weighed by DoD in the face of growing pressure from the National Guard Bureau and its congressional supporters to establish a separate component for space.

Gen. Joseph Lengyel, chief of the National Guard Bureau, told lawmakers in March that the issue is simple: If there is a Space Force, there should be a Space National Guard. Space units now serving under the Air National Guard and Army National should be aligned with the Space Force, Lengyel said. “We mirror the culture of our parent service.”

Eight states — Alaska, Hawaii, California, Colorado, Florida, New York, Arkansas and Ohio — and Guam have approximately 1,500 personnel who specialize in space operations. Most are from the Air National Guard and a small number are from the Army National Guard.

CBO estimated that if 1,500 personnel in existing Air national Guard and Army national Guard units transferred to the new Space National Guard, DoD would incur about $100 million in annual operations and support costs. There would also be onetime costs of about $20 million for the construction of additional facilities.

The states and territory affected by the transfer already have organizations to administer and command its national Guards, so moving units to the Space National Guard probably would not require much more overhead, said CBO. “However, it is likely that a small number of additional personnel would be needed in each state or territory affected, as well as some personnel for national functions,” the report said.

CBO’s estimate included a small force of approximately 100 additional full-time personnel to perform national functions and an additional 20 full-time personnel for each state and territory, or 260 additional personnel total. If such a lean force was not achievable, costs would be higher.

Although nobody has proposed a larger Space National Guard, CBO went ahead and estimated what one would cost if it were about one-third the size of the Space Force — the same size that the Air national Guard currently is in relation to the Air Force. That would be a Space National Guard of about 5,000 people, and its operational annual costs would be from $385 million to $490 million a year.

DoD and U.S. Space Force officials said they are considering options other than a Space National Guard to support the U.S. Space Force. The 大庄家彩票平台 National Defense Authorization Act on Dec. 20 created the U.S. Space Force but did not direct the establishment of a Space National Guard. The law did require the Pentagon to submit a report with recommendation on how reserve components would support the U.S. Space Force. Officials told SpaceNews that the report has been completed but has not yet been sent to Congress.

After making history on the first crewed flight of an orbital spacecraft launched from the United States in nearly nine years, two NASA astronauts are settling in on the International Space Station.

大庄家彩票平台ISS crew briefing

WASHINGTON — After making history on the first crewed flight of an orbital spacecraft launched from the United States in nearly nine years, two NASA astronauts are settling in on the International Space Station.

Astronauts Bob Behnken and Doug Hurley arrived at the ISS May 31, 19 hours after the Crew Dragon spacecraft they were on launched from the Kennedy Space Center. They will remain on the station for up to four months, joining the station’s crew of NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner.

While Behnken and Hurley trained primarily to test SpaceX’s commercial crew spacecraft so that NASA can certify it for use on more routine missions, the shortfall in crew on the ISS mean the two will also be spending time helping out with station operations.

That work has already started, Cassidy said in a June 1 media event. “Today is day one, and they’re hitting the ground running, unloading the vehicle. We’ve got HTV right at our feet and we’ll be working in there in very short order.”

The H-2 Transfer Vehicle, or HTV, is a Japanese cargo spacecraft that launched to the ISS May 20 and was berthed to the station five days later. It carried several tons of cargo for the station.

The HTV also brought to the station a final set of new lithium-ion batteries for the station’s power system, whose installation requires a set of spacewalks. Both Behnken and Cassidy have spacewalk experience, and NASA is considering having them perform those spacewalks, or EVAs, in the next several weeks.

“That’s going to take somewhere on the order of four to five EVAs to install those. At this point, we are looking at all options that could allow us to do those EVAs while we have Bob and Doug on board,” Kenny Todd, NASA deputy ISS program manager, said at a May 31 press conference.

How long Behnken and Hurley will remain on the station is an open question. NASA officials say several factors go into that assessment, including the health of the Crew Dragon spacecraft as well as the readiness of the next such spacecraft, which NASA currently plans to launch Aug. 30 on a mission called Crew-1 with four astronauts from NASA and the Japanese space agency JAXA on board.

Steve Stich, deputy program manager of the commercial crew program, said at the May 31 briefing that they’ll be watching the health of the solar arrays on the Crew Dragon in particular, looking for any degradation in their performance. Neither NASA nor SpaceX have explained why those solar panels appear to be more sensitive than those used on other spacecraft, or the station itself.

Stich said they will power on the Crew Dragon spacecraft weekly to test its solar arrays. “It’ll probably take a few weeks to get trending on that,” he said. “In a month or so, we’ll be able to make a decision as to how long to keep this vehicle in orbit.”

Behnken acknowledged that uncertainty during the June 1 media event. “Several recent crews have had a little bit more uncertainty than we’ve had historically for how long their mission duration was going to be,” he said, referring to NASA decisions to extend the stays of some individual astronauts, driven in part by commercial crew delays. “Doug and I have maybe the most uncertainty, because it could be relatively short or we could potentially double or triple, maybe, what was originally expected for us just a few short months ago.”

One ceremonial thing the Demo-2 astronauts have done is “capture the flag.” The final shuttle mission, STS-135, left behind on the station a small American flag that also flew on the first shuttle mission, STS-1 in 1981. The flag was to remain on the station until the next American crewed spacecraft arrived.

“Chris had it right on the hatch where we left it nine years ago,” said Hurley, who was part of the STS-135 crew. He then displayed the flag, to which he said Cassidy added a note: “Do not forget to take with Crew Dragon.”

“You can bet we will take it with us when we depart back to Earth,” Hurley said. “We are lucky enough to be able to take it 大庄家彩票平台 with us, and that will be our plan here in a month or two or three or four.”

A planned reorganization of the NASA mission directorate responsible for human spaceflight programs has been put on hold after its leader abruptly resigned last month.

]]>
大庄家彩票平台

WASHINGTON — A planned reorganization of the NASA mission directorate responsible for human spaceflight programs has been put on hold after its leader abruptly resigned last month.

During a June 1 webinar by the American Institute of Aeronautics and Astronautics, NASA Associate Administrator Steve Jurczyk said that a reorganization of the agency’s Human Exploration and Operations (HEO) Mission Directorate will be delayed until after the agency hires a successor to Doug Loverro, who left the agency May 19.

Loverro, who took over as associate administrator for human exploration and operations last December, had been working to restructure the directorate, which is responsible for the International Space Station, commercial crew, and exploration programs like the Space Launch System and Orion. That restructuring had not been completed before Loverro’s sudden resignation amid reports he violated procurement regulations during the selection process for the Human Landing System lunar lander program.

NASA had not disclosed what those changes entailed. Craig Kundrot, director of NASA’s Space Life and Physical Sciences Research and Applications Division, said at an advisory committee meeting in early April that the changes included moving his division from HEO to the Science Mission Directorate. “Look, however, for changes in the HEO structure coming in the near term, in probably a matter of weeks,” he said at that April 1 meeting.

Jurczyk said that any reorganization will be left to Loverro’s successor. “We’ve put the HEO reorganization on hold. We believe it’s important for the new AA [associate administrator] to come in and take a look at the organization and the programs, and make sure that where we were headed is the right structure for the new AA, and then make adjustments to the proposed reorganization.”

He said NASA was “actively” looking for a successor to Loverro. “Our goal is to have a new AA named within weeks, not months,” he said. “It’s really important to the organization and it’s really important for Artemis and all the programs.”

It took NASA more than three months to announce it hired Loverro, which agency officials said was the outcome of an extensive search after reassigning longtime associate administrator Bill Gerstenmaier to a senior adviser position in July 2019. While NASA announced hiring Loverro in mid-October, he did not start work until the beginning of December.

During the nearly five-month gap between Gerstenmaier’s reassignment and Loverro starting work, the HEO directorate was led on an acting basis by deputy associate administrator Ken Bowersox. He is again serving as acting associate administrator since Loverro’s departure.

Jurczyk used the webinar to provide a broad overview of agency activities, including how the coronavirus pandemic had affected many programs not considered essential. He said monthly reviews of major agency programs have recently focused on impacts from the pandemic, rather than assessing how those programs were following cost and schedule baselines set before the pandemic.

That includes, he said, discussing those cost and schedule impacts on programs to congressional appropriators, who will start work on fiscal year 2021 spending bills by July. “We won’t have it all, definitely,” he said of the effects of the pandemic on agency programs, “but we’ll have a good handle on it, given what’s happened and our projections what’s going to happen going forward.”

Jurczyk cited past comments by NASA Administrator Jim Bridenstine, who reassured agency employees that it’s unlikely that Congress will cut NASA’s budget in the next fiscal year. It’s not clear, though, that Congress will go along with the nearly $3 billion increase sought by the agency for 2021.

“Getting to an appropriations law every year is very challenging, and this year will be extremely challenging given COVID-19,” he said.

The U.S. military’s rescue units have supported NASA for six decades but now for the first time astronauts are flying in commercial capsules.

]]>
大庄家彩票平台

WASHINGTON — Three hours before the SpaceX Crew Dragon launch May 30, teams of combat rescue specialists staged at military bases in Florida, South Carolina and Hawaii went on alert status in the event of a mission abort.

The task force of about 150 personnel and eight aircraft is under the command of the U.S. Space Force’s 45th Space Wing at Patrick Air Force Base, Fla. It is deployed to ensure that if astronauts abort the mission, they are recovered anywhere in the world where they might land.

The U.S. military’s rescue units have supported NASA operations for six decades but this is a “new era” because astronauts are flying in commercial capsules and each requires different procedures and training, said Maj. Gen. John Shaw, commander of the Combined Force Space Component of U.S. Space Command at Vandenberg Air Force Base, California.

“We are supporting three capsules,” Shaw said June 1 during a SpaceNews online event. In addition to SpaceX Crew Dragon, troops are training to rescue astronauts from Boeing’s Starliner and Lockheed Martin’s Orion capsules.

“We had our first Starliner exercise in April,” said Lt. Col. Michael Thompson, the commander of the 45th Operations Group’s Detachment 3, the unit that oversees the training for the rescue missions. The detachment has about 30 full-time staff. For training and for actual missions, it is augmented by Air Force combat search and rescue units.

Boeing brought a Starliner test vehicle to Patrick Air Force Base for open ocean rescue training, said Thompson.

“Each of the capsules is unique,” he said. “The way we egress astronauts from Dragon is different than Starliner or Orion.”

During the Apollo era, said Thompson, the military deployed almost 6,000 personnel, 24 aircraft and seven naval vessels for astronaut rescue.

Detachment 3 also supports NASA astronauts when they fly on Russian Soyuz spacecraft.

Brig. Gen. Doug Schiess, commander of the 45th Space Wing, said Detachment 3 has been training for the Crew Dragon mission for five years.

The task force will be again on alert when Crew Dragon returns to Earth in a few months.

“We have to be prepared as they de-orbit back down,” said Schiess. “Hopefully SpaceX can get the capsule themselves. But again if there was an anomaly our team has to be prepared to be able to execute that rescue.”

For now the Space Force only supports NASA human spaceflight. If and when commercial companies begin to fly tourists to space, someone will have to decide how to handle contingency rescue operations, said Shaw.

“We’ll have to wait and see what happens,” he said. “We’ll see how that evolves and how the government chooses to regulate that.”

“As humans go into space there will be a need to prepare for rescue,” Shaw said. “Someone’s going to have to do that.”

Going forward, he said, “I think it’s very likely that the Department of Defense will be some part of that broader team in the support of human spaceflight program.”

The U.S. Space Force, said Shaw, “is not going to be sending humans into space for national security purposes anytime soon. Maybe a long time from now we’ll be doing that. But we will be supporting any humans that go into space for exploration. We will absolutely be doing that.”

Monday, June 1
2 p.m. Eastern/11 a.m. Pacific
via Zoom


With the successful launch and docking of NASA and SpaceX’s historic Demo-2 mission, SpaceNews talks with the Space Force brass supporting this and future commercial crew missions.

Maj. Gen. John Shaw and Brig. Gen. Doug Schiess join SpaceNews Staff Writer Sandra Erwin and Editor-in-Chief Brian Berger for a broad-based discussion on Space Force operations, including the U.S. military’s role in rescuing astronauts.

Shaw and Schiess were joined by the 45th Operations Group’s Detachment 3 commander, Lt. Col. Michael Thompson, to talk about how the military revived and trained for the astronaut-rescue role it has performed since the Apollo era.

Astronaut rescue is a small but important part of Maj. Gen. Shaw’s duties as the head of the U.S. Space Command’s Combined Force Space Component, which plans and executes day-to-day military space operations and has tactical control of American and multinational space forces during a conflict. 

Shaw, as a dual-hatted general, also leads the U.S. Space Force’s Space Operations Command, responsible for organizing, training and equipping the space forces that fly the U.S. military’s satellites, launches its rockets, stands sentinel over the orbital commons, and supports American and allied combat operations. 

Shaw also addressEd how the ongoing standup of the U.S. Space Force is bringing greater focus to the role space plays in all military operations and what’s at stake in defending the ultimate high ground. 

Among the questions we will explore during this free-to-attend webinar:

  • How has the U.S. military’s astronaut-rescue mission changed with NASA now relying on privately owned-and-operated crewed spacecraft?
  • What capabilities will the U.S. Space Force need going forward to support growing demands and challenges in space?
  • How has training for space missions been affected by COVID-19 and what impact has that had on the readiness of space forces?

Northrop Grumman is building the OmegA launch system with reliability as its most important component. Because when there’s a job that needs to be done in orbit, complete mission success is the only feature that matters.
