Microsoft to stop using China-based teams to support Department of Defense

china, Department of Defense, microsoft, Security, syndication / Mike M. / July 26, 2025

Last week, Microsoft announced that it would no longer use China-based engineering teams to support the Defense Department’s cloud computing systems, following ProPublica’s investigation of the practice, which cybersecurity experts said could expose the government to hacking and espionage.

But it turns out the Pentagon was not the only part of the government facing such a threat. For years, Microsoft has also used its global workforce, including China-based personnel, to maintain the cloud systems of other federal departments, including parts of Justice, Treasury and Commerce, ProPublica has found.

This work has taken place in what’s known as the Government Community Cloud, which is intended for information that is not classified but is nonetheless sensitive. The Federal Risk and Authorization Management Program, the US government’s cloud accreditation organization, has approved GCC to handle “moderate” impact information “where the loss of confidentiality, integrity, and availability would result in serious adverse effect on an agency’s operations, assets, or individuals.”

The Justice Department’s Antitrust Division has used GCC to support its criminal and civil investigation and litigation functions, according to a 2022 report. Parts of the Environmental Protection Agency and the Department of Education have also used GCC.

Microsoft says its foreign engineers working in GCC have been overseen by US-based personnel known as “digital escorts,” similar to the system it had in place at the Defense Department.

Nevertheless, cybersecurity experts told ProPublica that foreign support for GCC presents an opportunity for spying and sabotage. “There’s a misconception that, if government data isn’t classified, no harm can come of its distribution,” said Rex Booth, a former federal cybersecurity official who now is chief information security officer of the tech company SailPoint.

“With so much data stored in cloud services—and the power of AI to analyze it quickly—even unclassified data can reveal insights that could harm US interests,” he said.

Welcome to Edition 8.04 of the Rocket Report! The Pentagon’s Golden Dome missile defense shield will be a lot of things. Along with new sensors, command and control systems, and satellites, Golden Dome will require a lot of rockets. The pieces of the Golden Dome architecture operating in orbit will ride to space on commercial launch vehicles. And Golden Dome’s space-based interceptors will essentially be designed as flying fuel tanks with rocket engines. This shouldn’t be overlooked, and that’s why we include a couple of entries discussing Golden Dome in this week’s Rocket Report.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Space-based interceptors are a real challenge. The newly installed head of the Pentagon’s Golden Dome missile defense shield knows the clock is ticking to show President Donald Trump some results before the end of his term in the White House, Ars reports. Gen. Michael Guetlein identified command-and-control and the development of space-based interceptors as two of the most pressing technical challenges for Golden Dome. He believes the command-and-control problem can be “overcome in pretty short order.” The space-based interceptor piece of the architecture is a different story.

Proven physics, unproven economics … “I think the real technical challenge will be building the space-based interceptor,” Guetlein said. “That technology exists. I believe we have proven every element of the physics that we can make it work. What we have not proven is, first, can I do it economically, and then second, can I do it at scale? Can I build enough satellites to get after the threat? Can I expand the industrial base fast enough to build those satellites? Do I have enough raw materials, etc.?” Military officials haven’t said how many space-based interceptors will be required for Golden Dome, but outside estimates put the number in the thousands.

One big defense prime is posturing for Golden Dome. Northrop Grumman is conducting ground-based testing related to space-based interceptors as part of a competition for that segment of the Trump administration’s Golden Dome missile-defense initiative, The War Zone reports. Kathy Warden, Northrop Grumman’s CEO, highlighted the company’s work on space-based interceptors, as well as broader business opportunities stemming from Golden Dome, during a quarterly earnings call this week. Warden identified Northrop’s work in radars, drones, and command-and-control systems as potentially applicable to Golden Dome.

But here’s the real news … “It will also include new innovation, like space-based interceptors, which we’re testing now,” Warden continued. “These are ground-based tests today, and we are in competition, obviously, so not a lot of detail that I can provide here.” Warden declined to respond directly to a question about how the space-based interceptors Northrop Grumman is developing now will actually defeat their targets.

Trump may slash environmental rules for rocket launches. The Trump administration is considering slashing rules meant to protect the environment and the public during commercial rocket launches, changes that companies like Elon Musk’s SpaceX have long sought, ProPublica reports. A draft executive order being circulated among federal agencies, and viewed by ProPublica, directs Secretary of Transportation Sean Duffy to “use all available authorities to eliminate or expedite” environmental reviews for launch licenses. It could also, in time, require states to allow more launches or even more launch sites along their coastlines.

Getting political at the FAA … The order is a step toward the rollback of federal oversight that Musk, who has fought bitterly with the Federal Aviation Administration over his space operations, and others have pushed for. Commercial rocket launches have grown exponentially more frequent in recent years. In addition to slashing environmental rules, the draft executive order would make the head of the FAA’s Office of Commercial Space Transportation a political appointee. This is currently a civil servant position, but the last head of the office took a voluntary separation offer earlier this year.

There’s a SPAC for that. An unproven small launch startup is partnering with a severely depleted SPAC trust to do the impossible: go public in a deal they say will be valued at $400 million, TechCrunch reports. Innovative Rocket Technologies Inc., or iRocket, is set to merge with a Special Purpose Acquisition Company, or SPAC, founded by former Commerce Secretary Wilbur Ross. But the most recent regulatory filings by this SPAC showed it was in a tenuous financial position last year, with just $1.6 million held in trust. Likewise, iRocket isn’t flooded with cash. The company has raised only a few million in venture funding, a fraction of what would be needed to develop and test the company’s small orbital-class rocket, named Shockwave.

SpaceX traces a path to orbit for NASA. Two NASA satellites soared into orbit from California aboard a SpaceX Falcon 9 rocket Wednesday, commencing a $170 million mission to study a phenomenon of space physics that has eluded researchers since the dawn of the Space Age, Ars reports. The twin spacecraft are part of the NASA-funded TRACERS mission, which will spend at least a year measuring plasma conditions in narrow regions of Earth’s magnetic field known as polar cusps. As the name suggests, these regions are located over the poles. They play an important but poorly understood role in creating colorful auroras as plasma streaming out from the Sun interacts with the magnetic field surrounding Earth. The same process drives geomagnetic storms capable of disrupting GPS navigation, radio communications, electrical grids, and satellite operations.

Plenty of room for more … The TRACERS satellites are relatively small, each about the size of a washing machine, so they filled only a fraction of the capacity of SpaceX’s Falcon 9 rocket. Three other small NASA tech demo payloads hitched a ride to orbit with TRACERS, kicking off missions to test an experimental communications terminal, demonstrate an innovative scalable satellite platform made of individual building blocks, and study the link between Earth’s atmosphere and the Van Allen radiation belts. In addition to those missions, the European Space Agency launched its own CubeSat to test 5G communications from orbit. Five smallsats from an Australian company rounded out the group. Still, the Falcon 9 rocket’s payload shroud was filled with less than a quarter of the payload mass it could have delivered to the TRACERS mission’s targeted Sun-synchronous orbit.

Tianlong launch pad ready for action. Chinese startup Space Pioneer has completed a launch pad at Jiuquan spaceport in northwestern China for its Tianlong 3 liquid propellent rocket ahead of a first orbital launch, Space News reports. Space Pioneer said the launch pad passed an acceptance test, and ground crews raised a full-scale model of the Tianlong 3 rocket on the launch pad. “The rehearsal test was successfully completed,” said Space Pioneer, one of China’s leading private launch companies. The activation of the launch pad followed a couple of weeks after Space Pioneer announced the completion of static loads testing on Tianlong 3.

More to come … While this is an important step forward for Space Pioneer, construction of the launch pad is just one element the company needs to finish before Tianlong 3 can lift off for the first time. In June 2024, the company ignited Tianlong 3’s nine-engine first stage on a test stand in China. But the rocket broke free of its moorings on the test stand and unexpectedly climbed into the sky before crashing in a fireball nearby. Space Pioneer says the “weak design of the rocket’s tail structure was the direct cause of the failure” last year. The company hasn’t identified next steps for Tianlong 3, or when it might be ready to fly. Tianlong 3 is a kerosene-fueled rocket with nine main engines, similar in design architecture and payload capacity to SpaceX’s Falcon 9. Also, like Falcon 9, Tianlong 3 is supposed to have a recoverable and reusable first stage booster.

Dredging up an issue at Wallops. Rocket Lab has asked regulators for permission to transport oversized Neutron rocket structures through shallow waters to a spaceport off the coast of Virginia as it races to meet a September delivery deadline, TechCrunch reports. The request, which was made in July, is a temporary stopgap while the company awaits federal clearance to dredge a permanent channel to the Wallops Island site. Rocket Lab plans to launch its Neutron medium-lift rocket from the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Virginia, a lower-traffic spaceport that’s surrounded by shallow channels and waterways. Rocket Lab has a sizable checklist to tick off before Neutron can make its orbital debut, like mating the rocket stages, performing a “wet dress” rehearsal, and getting its launch license from the Federal Aviation Administration. Before any of that can happen, the rocket hardware needs to make it onto the island from Rocket Lab’s factory on the nearby mainland.

Kedging bets … Access to the channel leading to Wallops Island is currently available only at low tides. So, Rocket Lab submitted an application earlier this year to dredge the channel. The dredging project was approved by the Virginia Marine Resources Commission in May, but the company has yet to start digging because it’s still awaiting federal sign-off from the Army Corps of Engineers. As the company waits for federal approval, Rocket Lab is seeking permission to use a temporary method called “kedging” to ensure the first five hardware deliveries can arrive on schedule starting in September. We don’t cover maritime issues in the Rocket Report, but if you’re interested in learning a little about kedging, here’s a link.

Any better ideas for an Exploration Upper Stage? Not surprisingly, Congress is pushing back against the Trump administration’s proposal to cancel the Space Launch System, the behemoth rocket NASA has developed to propel astronauts back to the Moon. But legislation making its way through the House of Representatives includes an interesting provision that would direct NASA to evaluate alternatives for the Boeing-built Exploration Upper Stage, an upgrade for the SLS rocket set to debut on its fourth flight, Ars reports. Essentially, the House Appropriations Committee is telling NASA to look for cheaper, faster options for a new SLS upper stage.

CYA EUS? … The four-engine Exploration Upper Stage, or EUS, is an expensive undertaking. Last year, NASA’s inspector general reported that the new upper stage’s development costs had ballooned from $962 million to $2.8 billion, and the project had been delayed more than six years. That’s almost a year-for-year delay since NASA and Boeing started development of the EUS. So, what are the options if NASA went with a new upper stage for the SLS rocket? One possibility is a modified version of United Launch Alliance’s dual-engine Centaur V upper stage that flies on the Vulcan rocket. It’s no longer possible to keep flying the SLS rocket’s existing single-engine upper stage because ULA has shut down the production line for it.

Raising Super Heavy from the deep. For the second time, SpaceX has retrieved an engine section from one of its Super Heavy boosters from the Gulf of Mexico, NASASpaceflight.com reports. Images posted on social media showed the tail end of a Super Heavy booster being raised from the sea off the coast of northern Mexico. Most of the rocket’s 33 Raptor engines appear to still be attached to the lower section of the stainless steel booster. Online sleuths who closely track SpaceX’s activities at Starbase, Texas, have concluded the rocket recovered from the Gulf is Booster 13, which flew on the sixth test flight of the Starship mega-rocket last November. The booster ditched in the ocean after aborting an attempted catch back at the launch pad in South Texas.

But why? … SpaceX recovered the engine section of a different Super Heavy booster from the Gulf last year. The company’s motivation for salvaging the wreckage is unclear. “Speculated reasons include engineering research, environmental mitigation, or even historical preservation,” NASASpaceflight reports.

Trump, who promised to save TikTok, threatens to shut down TikTok

bytedance, china, Donald Trump, national security, Policy, tiktok, us-china trade war / Mike M. / July 25, 2025

Earlier this month, Trump had claimed that he wasn’t “confident” that China would approve the deal, even though he thought it was “good for China.” Analysts have suggested that China views TikTok as a bargaining chip in its tariff negotiations with Trump, which continue to not go smoothly, and it may be OK with the deal but unwilling to release the bargaining chip without receiving key concessions from the US.

US-China tariff talks complicate TikTok deal

For now, the US and China are enjoying a 90-day truce that could end in August, about a month before the deadline Trump set to sell TikTok in mid-September. In an op-ed this week, Sean Stein, the president of the US-China Business Council, suggested that “it is almost inevitable” that the US and China will extend the 90-day truce, indicating that Trump is far from securing a favorable deal for the US following weeks of tense negotiations with America’s biggest trade adversary.

It’s possible that the Trump administration is threatening to shut down TikTok in hopes that China will make a concession ahead of the September deadline. Lutnick’s comments could even mean that Trump has possibly failed to clinch the deal, which could have untold consequences in the US-China trade war, perhaps wounding Trump’s ego after his posturing that only he can save TikTok.

For TikTok fans and Americans who rely on TikTok for their livelihoods, betting on Trump’s dealmaking skills likely continues to feel tenuous as Lutnick forecasts a potential shutdown that could come within weeks.

“If that deal gets approved by the Chinese, then that deal will happen,” Lutnick said. “If they don’t approve it, then TikTok is going to go dark, and those decisions are coming very soon.”

White House unveils sweeping plan to “win” global AI race through deregulation

AI, AI and work, AI development tools, AI ethics, AI infrastructure, AI law, AI regulation, AI research, AI security, biosecurity, Biz & IT, china, Chips Act, data centers, David Sacks, Deepfakes, Department of Commerce, Donald Trump, Energy, Export controls, machine learning, Michael Kratsios, national security, NIST, Open Source, Policy, semiconductors, White House / Kris Guyer / July 24, 2025

Trump’s plan was not welcomed by everyone. J.B. Branch, Big Tech accountability advocate for Public Citizen, in a statement provided to Ars, criticized Trump as giving “sweetheart deals” to tech companies that would cause “electricity bills to rise to subsidize discounted power for massive AI data centers.”

Infrastructure demands and energy requirements

Trump’s new AI plan tackles infrastructure head-on, stating that “AI is the first digital service in modern life that challenges America to build vastly greater energy generation than we have today.” To meet this demand, it proposes streamlining environmental permitting for data centers through new National Environmental Policy Act (NEPA) exemptions, making federal lands available for construction and modernizing the power grid—all while explicitly rejecting “radical climate dogma and bureaucratic red tape.”

The document embraces what it calls a “Build, Baby, Build!” approach—echoing a Trump campaign slogan—and promises to restore semiconductor manufacturing through the CHIPS Program Office, though stripped of “extraneous policy requirements.”

On the technology front, the plan directs Commerce to revise NIST’s AI Risk Management Framework to “eliminate references to misinformation, Diversity, Equity, and Inclusion, and climate change.” Federal procurement would favor AI developers whose systems are “objective and free from top-down ideological bias.” The document strongly backs open source AI models and calls for exporting American AI technology to allies while blocking administration-labeled adversaries like China.

Security proposals include high-security military data centers and warnings that advanced AI systems “may pose novel national security risks” in cyberattacks and weapons development.

Critics respond with “People’s AI Action Plan”

Before the White House unveiled its plan, more than 90 organizations launched a competing “People’s AI Action Plan” on Tuesday, characterizing the Trump administration’s approach as “a massive handout to the tech industry” that prioritizes corporate interests over public welfare. The coalition includes labor unions, environmental justice groups, and consumer protection nonprofits.

Whistleblower scientists outline Trump’s plan to politicize and dismantle NSF

china, doge, Donald Trump, National Science Foundation, NSF, Policy, trump administration / Rejus Almole / July 24, 2025

Nearly 150 employees of the National Science Foundation (NSF) sent an urgent letter of dissent to Congress on Tuesday, warning that the Trump administration’s recent “politically motivated and legally questionable” actions threaten to dismantle the independent “world-renowned scientific agency.”

Most NSF employees signed the letter anonymously, with only Jesus Soriano, the president of their local union (AFGE Local 3403), publicly disclosing his name. Addressed to Rep. Zoe Lofgren (D-Calif.), ranking member of the House Committee on Science, Space, and Technology, the letter insisted that Congress intervene to stop steep budget cuts, mass firings and grant terminations, withholding of billions in appropriated funds, allegedly coerced resignations, and the sudden eviction of NSF from its headquarters planned for next year.

Perhaps most disturbingly, the letter revealed “a covert and ideologically driven secondary review process by unqualified political appointees” that is now allegedly “interfering with the scientific merit-based review system” that historically has made NSF a leading, trusted science agency. Soriano further warned that “scientists, program officers, and staff” have all “been targeted for doing their jobs with integrity” in what the letter warned was “a broader agenda to dismantle institutional safeguards, impose demagoguery in research funding decisions, and undermine science.”

At a press conference with Lofgren on Wednesday, AFGE National President Everett Kelley backed NSF workers and reminded Congress that their oversight of the executive branch “is not optional.”

Taking up the fight, Lofgren promised to do “all” that she “can” to protect the agency and the entire US scientific enterprise.

She also promised to protect Soriano from any retaliation, as some federal workers, including NSF workers, alleged they’ve already faced retaliation, necessitating their anonymity to speak publicly. Lofgren criticized the “deep shame” of the Trump administration creating a culture of fear permeating NSF, noting that the “horrifying” statements in the letter are “all true,” yet filed as a whistleblower complaint as if they’re sharing secrets.

BYD has caught up with Tesla in the global EV race. Here’s how.

BYD, Cars, china, elon musk, EVs, syndication, Tesla / Kris Guyer / July 15, 2025

“Tesla has partnered with Baidu [a Chinese search and AI group] but Baidu can’t disclose all the data points to Tesla,” Duo adds. “The real-world data is definitely more valuable.”

Home field advantage

While BYD might have home turf advantage when it comes to data collection and security, Wang’s late pivot to driverless functionality has created some risks for the group.

One is question marks over financial sustainability. Price wars among Chinese carmakers are putting margins and the industry’s balance sheet under strain as Beijing demands more action to protect suppliers in the world’s largest car market.

It has also opened up some rare gaps in BYD’s otherwise formidable vertical integration. Its market leadership has also enabled it to pressure suppliers for price cuts and extended payment terms, allowing it to rigorously control costs.

But according to Chris McNally, an analyst with US investment bank Evercore, the God’s Eye platform uses software and hardware partners, including Momenta, a Chinese group backed by General Motors in the US, and some chips from Nvidia.

BYD EVP next to car — BYD’s executive vice-president Stella Li said competition with Tesla in EVs and autonomous technology would accelerate innovation, ultimately making BYD a “better’” company. Credit: Joel Saget/AFP/Getty Images

For years, the risks associated with reliance on US-made chips in particular have hovered over the Chinese car sector—plans for driverless systems could be held back at any moment by US export controls or sanctions.

“Given the geopolitical environment, no one will invest in a technology with such a high risk that they’re still relying on foreign technology,” says Raymond Tsang, an automotive technology expert with Bain in Shanghai.

However, these vulnerabilities might not persist. Analysts believe BYD will soon develop most of its driverless systems in house and increasingly swap out Nvidia chips for those made by Beijing-based Horizon Robotics. “This is the BYD way to drive costs down,” McNally says.

It would also be consistent with a broader shift towards self-reliance in key technologies, in response to Washington’s steadily increasing restrictions on technology exports to China.

Yuqian Ding, a veteran Beijing-based auto analyst with HSBC, says that while BYD has not talked about developing a robotaxi service, executives have made “very clear” their plans to develop in-house all the important software and hardware needed for autonomous vehicles.

Wang, the BYD boss, has also previously indicated to analysts that the company has all the tech and know-how to develop robots, in another potential long-term challenge to Musk.

“With more than 5 million scale per annum, they can do everything,” Ding says, adding: “That’s the ultimate goal . . . Their target is much closer to Tesla.”

In an interview with the Financial Times this year, BYD’s executive vice-president Stella Li said competition with Tesla in EVs and autonomous technology would accelerate innovation, ultimately making BYD a “better” company.

“In the future, if you are not producing an electric car, if you’re not introducing technology in intelligence and autonomous driving, you will be out,” she warned.

Welcome to Edition 8.02 of the Rocket Report! It’s worth taking a moment to recognize an important anniversary in the history of human spaceflight next week. Fifty years ago, on July 15, 1975, NASA launched a three-man crew on an Apollo spacecraft from Florida and two Russian cosmonauts took off from Kazakhstan, on course to link up in low-Earth orbit two days later. This was the first joint US-Russian human spaceflight mission, laying the foundation for a strained but enduring partnership on the International Space Station. Operations on the ISS are due to wind down in 2030, and the two nations have no serious prospects to continue any partnership in space after decommissioning the station.

Sizing up Europe’s launch challengers. The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent’s incumbent launch service provider, Ars reports. The five small launch companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar’s Spectrum rocket failed moments after liftoff from Norway on a test flight in March. None of these companies is guaranteed an ESA contract or funding. Over the next several months, ESA and the five launch companies will negotiate with European governments for funding leading up to ESA’s ministerial council meeting in November, when ESA member states will set the agency’s budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

Let’s rank ’em … Ars Technica’s space reporters ranked the five selectees for the European Launcher Challenge in order from most likely to least likely to reach orbit. We put Munich-based Isar Aerospace, the most well-funded of the group, at the top of the list after attempting its first orbital launch earlier this year. Paris-based MaiaSpace, backed by ArianeGroup, comes in second, with plans for a partially reusable rocket. Rocket Factory Augsburg, another Germany company, is in third place after getting close to a launch attempt last year before its first rocket blew up on a test stand. Spanish startup PLD Space is fourth, and Britain’s Orbex rounds out the list. (submitted by EllPeaTea)

Japan’s Interstellar Technologies rakes in more cash. Interstellar Technologies raised 8.9 billion yen ($61.8 million) to boost development of its Zero rocket and research and development of satellite systems, Space News reports. The money comes from Japanese financial institutions, venture capital funds, and debt financing. Interstellar previously received funding through agreements with the Japanese government and Toyota, which Interstellar says will add expertise to scale manufacturing of the Zero rocket for “high-frequency, cost-effective launches.” The methane-fueled Zero rocket is designed to deploy a payload of up to 1 metric ton (2,200 pounds) into low-Earth orbit. The unfortunate news from Interstellar’s fundraising announcement is that the company has pushed back the debut flight of the Zero rocket until 2027.

Straight up … Interstellar has aspirations beyond launch vehicles. The company is also developing a satellite communications business, and some of the money raised in the latest investment round will go toward this segment of the company. Interstellar is open about comparing its ambition to that of SpaceX. “On the satellite side, Interstellar is developing communications satellites that benefit from the company’s own launch capabilities,” the company said in a statement. “Backed by Japan’s Ministry of Internal Affairs and Communications and JAXA’s Space Strategy Fund, the company is building a vertically integrated model, similar to SpaceX’s approach with Starlink.”

Korean startup completes second-stage qual testing. South Korean launch services company Innospace says it has taken another step toward the inaugural launch of its Hanbit-Nano rocket by the year’s end with the qualification of the second stage, Aviation Week & Space Technology reports. The second stage uses an in-house-developed 34-kilonewton (7,643-pound-thrust) liquid methane engine. Innospace says the engine achieved a combustion time of 300 seconds, maintaining stability of the fuel and oxidizer supply system, structural integrity, and the launch vehicle integrated control system.

A true micro-launcher … Innospace’s rocket is modest in size and capacity, even among its cohorts in the small launch market. The Hanbit-Nano rocket is designed to launch approximately 200 pounds (90 kilograms) of payload into Sun-synchronous orbit. “With the success of this second stage engine certification test, we have completed the development of the upper stage of the Hanbit-Nano launch vehicle,” said Kim Soo-jong, CEO of Innospace. “This is a very symbolic and meaningful technological achievement that demonstrates the technological prowess and test operation capabilities that Innospace has accumulated over a long period of time, while also showing that we have entered the final stage for commercial launch. Currently, all executives and staff are doing their best to successfully complete the first stage certification test, which is the final gateway for launch, and we will make every effort to prepare for a smooth commercial launch in the second half of the year.”

Two companies forge unlikely alliance in Dubai. Two German entrepreneurs have joined forces with a team of Russian expats steeped in space history to design a rocket using computational AI models, Payload reports. The “strategic partnership” is between LEAP 71, an AI-enabled design startup, and Aspire Space, a company founded by the son of a Soviet engineer who was in charge of launching Zenit rockets from the Baikonur Cosmodrome in Kazakhstan in the 1980s. The companies will base their operations in Dubai. The unlikely pairing aims to develop a new large reusable launch vehicle capable of delivering up to 15 metric tons to low-Earth orbit. Aspire Space is a particularly interesting company if you’re a space history enthusiast. Apart from the connections of Aspire’s founder to Soviet space history, Aspire’s chief technology officer, Sergey Sopov, started his career at Baikonur working on the Energia heavy-lift rocket and Buran space shuttle, before becoming an executive at Sea Launch later in his career.

Trust the computer … It’s easy to be skeptical about this project, but it has attracted an interesting group of people. LEAP 71 has just two employees—its two German co-founders—but boasts lofty ambitions and calls itself a “pioneer in AI-driven engineering.” As part of the agreement with Aspire Space, LEAP 71 will use a proprietary software program called Noyron to design the entire propulsion stack for Aspire’s rockets. The company says its AI-enabled design approach for Aspire’s 450,000-pound-thrust engine will cut in half the time it took other rocket companies to begin test-firing a new engine of similar size. Rudenko forecasts Aspire’s entire project, including a launcher, reusable spacecraft, and ground infrastructure to support it all, will cost more than $1 billion. So far, the project is self-funded, Rudenko told Payload. (submitted by Lin Kayser)

Russia launches ISS resupply freighter. A Russian Progress supply ship launched July 3 from the Baikonur Cosmodrome in Kazakhstan atop a Soyuz-2.1a rocket, NASASpaceflight reports. Packed with 5,787 pounds (2,625 kilograms) of cargo and fuel, the Progress MS-31 spacecraft glided to an automated docking at the International Space Station two days later. The Russian cosmonauts living aboard the ISS will unpack the supplies carried inside the Progress craft’s pressurized compartment. This was the eighth orbital launch of the year by a Russian rocket, continuing a downward trend in launch activity for the Russian space program in recent years.

Celebrating a golden anniversary … The Soyuz rocket that launched Progress MS-31 was painted an unusual blue and white scheme, as it was originally intended for a commercial launch that was likely canceled after Russia’s invasion of Ukraine. It also sported a logo commemorating the 50th anniversary of the Apollo-Soyuz mission in July 1975.

Chinese rocket moves closer to first launch. Chinese commercial launch firm Orienspace is aiming for a late 2025 debut of its Gravity-2 rocket following a recent first-stage engine hot fire test, Space News reports. The “three-in-one” hot fire test verified the performance of the Gravity-2 rocket’s first stage engine, servo mechanisms, and valves that regulate the flow of propellants into the engine, according to a press release from Orienspace. The Gravity-2 rocket’s recoverable and reusable first stage will be powered by nine of these kerosene-fueled engines. The recent hot fire test “lays a solid foundation” for future tests leading up to the Gravity-2’s inaugural flight.

Extra medium … Orienspace’s first rocket, the solid-fueled Gravity-1, completed its first successful flight last year to place multiple small satellites into orbit. Gravity-2 is a much larger vehicle, standing 230 feet (70 meters) tall, the same height as SpaceX’s Falcon 9 rocket. Orienspace’s new rocket will fly in a core-only configuration or with the assistance of two solid rocket boosters. An infographic released by Orienspace in conjunction with the recent engine hot fire test indicates the Gravity-2 rocket will be capable of hauling up to 21.5 metric tons (47,400 pounds) of cargo into low-Earth orbit, placing its performance near the upper limit of medium-lift launchers.

Senator calls out Texas for trying to steal space shuttle. A political effort to remove space shuttle Discovery from the Smithsonian and place it on display in Texas encountered some pushback on Thursday, as a US senator questioned the expense of carrying out what he described as a theft, Ars reports. “This is not a transfer. It’s a heist,” said Sen. Dick Durbin (D-Ill.) during a budget markup hearing before the Senate Appropriations Committee. “A heist by Texas because they lost a competition 12 years ago.” In April, Republican Sens. John Cornyn and Ted Cruz, both representing Texas, introduced the “Bring the Space Shuttle Home Act” that called for Discovery to be relocated from the National Air and Space Museum’s Steven F. Udvar-Hazy Center in northern Virginia and displayed at Space Center Houston. They then inserted an $85 million provision for the shuttle relocation into the Senate version of the “One Big Beautiful Bill,” which, to comply with Senate rules, was more vaguely worded but was meant to achieve the same goal. That bill was enacted on July 4, when President Donald Trump signed it into law.

Dollar signs … As ridiculous as it is to imagine spending $85 million on moving a space shuttle from one museum to another, it’ll actually cost a lot more to do it safely. Citing research by NASA and the Smithsonian, Durbin said that the total was closer to $305 million and that did not include the estimated $178 million needed to build a facility to house and display Discovery once in Houston. Furthermore, it was unclear if Congress even has the right to remove an artifact, let alone a space shuttle, from the Smithsonian’s collection. The Washington, DC, institution, which serves as a trust instrumentality of the US, maintains that it owns Discovery. The paperwork signed by NASA in 2012 transferred “all rights, interest, title, and ownership” for the spacecraft to the Smithsonian. “This will be the first time ever in the history of the Smithsonian someone has taken one of their displays and forcibly taken possession of it. What are we doing here? They don’t have the right in Texas to claim this,” said Durbin.

Starbase keeps getting bigger. Cameron County, Texas, has given SpaceX the green light to build an air separator facility, which will be located less than 300 feet from the region’s sand dunes, frustrating locals concerned about the impact on vegetation and wildlife, the Texas Tribune reports. The commissioners voted 3–1 to give Elon Musk’s rocket company a beachfront construction certificate and dune protection permit, allowing the company to build a facility to produce gases needed for Starship launches. The factory will separate air into nitrogen and oxygen. SpaceX uses liquid oxygen as a propellant and liquid nitrogen for testing and operations.

Saving the roads … By having the facility on site, SpaceX hopes to make the delivery of those gases more efficient by eliminating the need to have dozens of trucks deliver them from Brownsville. The company says they need more than 200 trucks of liquid nitrogen and oxygen delivered for each launch, a SpaceX engineer told the county during a meeting last week. With their application, SpaceX submitted a plan to mitigate expected negative effects on 865 square feet of dune vegetation and 20 cubic yards of dunes, as well as compensate for expected permanent impacts to 7,735 square feet of dune vegetation and 465 cubic yards of dunes. While the project will be built on property owned by SpaceX, the county holds the authority to manage the construction that affects Boca Chica’s dunes.

ULA is stacking its third Vulcan rocket. A little more than a week after its most recent Atlas V rocket launch, United Launch Alliance rolled a Vulcan booster to the Vertical Integration Facility at Cape Canaveral Space Force Station in Florida on July 2 to begin stacking its first post-certification Vulcan rocket, Spaceflight Now reports. The operation, referred to by ULA as Launch Vehicle on Stand (LVOS), is the first major milestone toward the launch of the third Vulcan rocket. The upcoming launch will be the first operational flight of ULA’s new rocket with a pair of US military payloads, following two certification flights in 2024.

For the second time … This is the second time that this particular Vulcan booster was brought to Space Launch Complex 41 in anticipation of a launch campaign. It was previously readied in late October of last year in support of the USSF-106 mission, the Space Force’s designation for the first national security launch to use the Vulcan rocket. However, plans changed as the process of certifying Vulcan to fly government payloads took longer than expected, and ULA pivoted to launch two Atlas V rockets on commercial missions from the same pad before switching back to Vulcan launch preps.

Progress report on China’s Moon rocket. China’s self-imposed deadline of landing astronauts on the Moon by 2030 is now just five years away, and we’re starting to see some tangible progress. Construction of the launch pad for the Long March 10 rocket, the massive vehicle China will use to launch its first crews toward the Moon, is well along at the Wenchang Space Launch Site on Hainan Island. An image shared on the Chinese social media platform Weibo, and then reposted on X, shows the Long March 10’s launch tower near its final height. A mobile launch platform presumably for the Long March 10 is under construction nearby.

Super heavy … The Long March 10 will be China’s most powerful rocket to date, with the ability to dispatch 27 metric tons of payload toward the Moon, a number comparable to NASA’s Space Launch System. Designed for partial reusability, the Long March 10 will use an all-liquid propulsion system and stand more than 92 meters (300 feet) tall. The rocket will launch Chinese astronauts inside the nation’s next-generation Mengzhou crew capsule, along with a lunar lander to transport crew members from lunar orbit to the surface of the Moon using an architecture similar to NASA’s Apollo program.

China jumps ahead in the race to achieve a new kind of reuse in space

china, geosynchronous orbit, military space, orbital refueling, satellite servicing, shijian-21, shijian-25, Space, us space command, US Space Force / Kris Guyer / July 8, 2025

The SJ-21 and SJ-25 satellites “merged” on July 2 and have remained together since then.

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling.

China’s Shijian-21 and Shijian-25 satellites, known as SJ-21 and SJ-25 for short, likely docked together in geosynchronous orbit sometime last week. This is the conclusion of multiple civilian satellite trackers using open source imagery showing the two satellites coming together, then becoming indistinguishable as a single object.

Chinese officials have released no recent public information on what the two satellites are up to, but they’ve said a bit about their missions in prior statements.

SJ-25, which launched in January, is designed “for the verification of satellite fuel replenishment and life extension service technologies,” according to the Shanghai Academy of Spaceflight Technology, the Chinese state-owned contractor that developed the satellite. SJ-21 launched in 2021 and docked with a defunct Chinese Beidou navigation satellite in geosynchronous orbit, then towed it to a higher altitude for disposal before returning to the geosynchronous belt. Chinese officials described this demonstration as a test of “space debris mitigation” techniques.

More than meets the eye

These kinds of technologies are dual-use, meaning they have civilian and military applications. For example, a docking in geosynchronous orbit could foretell an emerging capability for China to approach, capture, and disable another country’s satellite. At the same time, the US Space Force is interested in orbital refueling as it seeks out ways to extend the lives of military satellites, which are often limited by finite fuel supplies.

The Space Force sometimes calls this concept dynamic space operations. While some military leaders remain skeptical about the payoff of in-space refueling, the Space Force has an agreement with Astroscale to perform the first refueling of a US military asset in orbit as soon as next year.

China appears to be poised to beat the US Space Force to the punch. The apparent docking of the two satellites last week suggests SJ-21 is the target for SJ-25’s refueling demonstration, and US officials are watching. Two of the Space Force’s inspector satellites, known by the acronym GSSAP, positioned themselves near SJ-21 and SJ-25 to get a closer look.

Retired Space Force Lt. Gen. John Shaw is a vocal proponent of dynamic space operations. Because of this, he’s interested in what happens with SJ-21 and SJ-25. Shaw was deputy commander of US Space Command before his retirement in 2023. In this role, Shaw had some oversight over GSSAP satellites as they roamed geosynchronous orbit.

“The theory behind dynamic space operations stemmed from a kind of operational frustration with our inability to conduct the full range of activities with GSSAP that we wanted to at Space Command, as the warfighter—largely due to the combination of fixed fuel availability and expected satellite lifetime,” Shaw told Ars.

As other countries, mainly China, step up their clandestine activities in orbit, military officials are asking more of the GSSAP satellites.

“It was operationally driven then, a couple years ago, but it’s now manifesting itself in much wider ways than even it did back then, particularly in the face of activities by potential adversaries,” Shaw said. “That’s why I’m more confident and even more fanatical about it.”

Geosynchronous orbit is a popular location for military and commercial satellites. At an altitude of some 22,236 miles (35,786 kilometers), a satellite’s orbital velocity perfectly matches the speed of Earth’s rotation, meaning a spacecraft has a fixed view of the same region of the planet 24 hours per day. This is useful for satellites providing military forces with secure strategic communications and early warning of missile attacks.

Now, geosynchronous orbit is becoming a proving ground for new kinds of spacecraft to inspect or potentially attack other satellites. Ground-based anti-satellite missiles aren’t as useful in striking targets in high-altitude orbits, and there’s a consensus that, if you were to attack an enemy satellite, it would make more sense to use a weapons platform already in space that could move in and connect with the target without blowing it up and creating a cloud of dangerous space junk.

Keeping watch

The US military’s GSSAP satellites began launching in 2014. They carry enough propellant to maneuver around geosynchronous orbit and approach objects for closer inspection, but there’s a limit to what they can do. Six GSSAP satellites have been launched to date, but the Space Force decommissioned one of them in 2023. Meanwhile, China’s satellite operators are watching the watchers.

“We’ve seen where GSSAP safely and responsibly approaches a Chinese vehicle, and it just quickly maneuvers away,” Shaw said. “We tend to fly our GSSAPs like dirigibles, using relatively slow, minimum energy transfer approaches. The Chinese know that we do that, so it is relatively easy for them to maneuver away today to avoid such an approach.

“If tomorrow they’re able to refuel at will and operate even more dynamically, then the marginal cost of those maneuvers for them becomes even lower, and the challenge for GSSAP becomes even greater,” Shaw said.

China launched a satellite into geosynchronous orbit in 2016 with a robotic arm that could grab onto another object in space, then sent SJ-21 into orbit four years ago on its “space debris mitigation” mission.

Northrop Grumman launched two satellites in 2019 and 2020 that accomplished the first dockings in geosynchronous orbit. Northrop’s satellites, which it calls Mission Extension Vehicles, took control of two aging commercial communications satellites running low on fuel, maneuvering them to new locations and allowing them to continue operating for several more years. It’s easy to see that this kind of technology could be used for commercial or military purposes.

But these Mission Extension Vehicles don’t have the ability to transfer fluids from one satellite to another. That is the step China is taking with SJ-21 and SJ-25, presumably with hydrazine and nitrogen tetroxide propellants, which most satellites use because they combust on contact with one another.

US Space Command’s Joint Commercial Operations cell, which collects unclassified satellite monitoring data to bolster the military’s classified data sources, estimated the SJ-21 and SJ-25 satellites “merged” on July 2 and have remained together since then. The video below, released by s2a systems, shows SJ-25 approaching SJ-21 on June 30.

The unclassified data does not confirm that the two satellites actually docked, but that is likely what happened. The satellites came together, or merged, on June 13 and June 30 but separated again within a few hours. These may have been practice runs, aborted docking attempts, or sudden maneuvers to avoid the prying eyes of the US military’s GSSAP satellites loitering nearby.

Now, the SJ-21 and SJ-25 have been flying together for more than five days with no discernible changes detected from ground-based telescopes. Thousands of miles over the equator, the two satellites appear only as dots in the viewfinders of these telescopes positioned around the globe.

What we don’t know

COMSPOC is a Pennsylvania-based company that collects and processes data from commercial satellite tracking sensors. COMSPOC fuses optical telescope imagery with radar tracking and passive radio frequency (RF) data, which uses radio signals to measure exact distances to satellites in space, to get the best possible estimate of a spacecraft’s position.

“With most telescopes… at 1 kilometer or a half a kilometer, somewhere in there, you’re going to start to lose it when they get that close,” said Paul Graziani, COMSPOC’s founder and CEO, in an interview with Ars. “I think it’d be difficult for any telescope, even a really capable one, to get within 100 meters. That seems to be a stretch for telescopes.”

That’s why it’s helpful to add radar and RF data to the mix.

“When you add all of that together, you become much better than the 1-kilometer [precision] that a ‘scope might be,” said Joe Callaro, COMSPOC’s director of operations. “RF tells you if part of that blob is moving and the other part isn’t, and even when they all become one pixel, you can tell things about that.”

Even then, companies like COMSPOC have a degree of uncertainty in their conclusions unless Chinese or US officials make a more definitive statement.

“We are not working with the government,” Callaro told Ars before last week’s apparent docking. “We are not clearing this. The charge that I have for my team is we won’t make assertions as to what’s going on. We will only tell what our software gives us as a solution. We can say, ‘Here are the elements, here’s the visual, but what it means and what it’s doing, we will not assert.’

“We will not say they’re docked because unless they told me, I wouldn’t know that,” Callaro said. “So, we will say they’ve been together for this amount of time, that the mission could have happened, and then they separated, became two, and separated at whatever speed.”

Without any updates from China, observers won’t know for sure if the servicing demo was successful until the satellites detach. Then, US officials and independent analysts will watch to see if SJ-21 makes any substantial maneuvers, which might indicate the satellite has a full tank of gas.

SJ-21’s behavior for the last couple of years suggested it was running empty after undertaking large propulsive maneuvers to capture the Chinese Beidou satellite and move it to a different orbit.

Callaro served as a tactician in the Air Force’s Joint Space Operations Center, then joined the Aerospace Corporation before taking the job as operations lead at COMSPOC. He doesn’t buy China’s suggestion that SJ-21 was purely an experiment in collecting space debris.

“That is not how I see that at all,” Callaro said. “The fact that we can calculate all the maneuvers it takes to get out and get back, and the fact that afterwards, it spent a couple of years basically not moving, probably because it was low on fuel, sets up the idea [that there’s more to SJ-21’s mission]. Now, SJ-25 goes out there, and it’s supposed to be a fuel tank, and it’s perfectly aligned with SJ-21 and now we see this happening, tells me that it’s much more a counter-space capability than it is a trash remove. But that’s what they say.”

Unless China makes a public statement on the refueling of SJ-21 by SJ-25, observers won’t know for sure if the servicing demo was successful until the satellites detach. Then, US officials and independent analysts will watch to see if SJ-21 makes any substantial maneuvers, which might indicate the satellite has a full tank of gas for whatever mission Chinese officials send it off to do next.

Trade war truce between US and China is back on

china, china tariffs, Policy, syndication, tariffs, trade / Rejus Almole / June 11, 2025

Both countries agreed in Geneva last month to slash their respective tariffs by 115 percentage points and provided a 90-day window to resolve the trade war.

But the ceasefire came under pressure after Washington accused Beijing of reneging on an agreement to speed up the export of rare earths, while China criticized new US export controls.

This week’s talks to resolve the impasse were held in the historic Lancaster House mansion in central London, a short walk from Buckingham Palace, which was provided by the British government as a neutral ground for the talks.

Over the two days, the US team, which included Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick, and US trade representative Jamieson Greer, [met with] the Chinese delegation, which was led by He Lifeng, a vice-premier responsible for the economy.

The negotiations were launched to ensure Chinese exports of rare earths to the US and American technology export controls on China did not derail broader talks between the sides.

Ahead of the first round of talks in Geneva, Bessent had warned that the high level of mutual tariffs had amounted to an effective embargo on bilateral trade.

Chinese exports to the US fell more steeply in May compared with a year earlier than at any point since the pandemic in 2020.

The US had said China was not honoring its pledge in Geneva to ease restrictions on rare earths exports, which are critical to the defense, car, and tech industries, and was dragging its feet over approving licenses for shipments, affecting manufacturing supply chains in the US and Europe.

Beijing has accused the US of “seriously violating” the Geneva agreement after it announced new restrictions on sales of chip design software to Chinese companies.

It has also objected to the US issuing new warnings on the global use of Huawei chips and canceling visas for Chinese students.

Separately, a US federal appeals court on Tuesday allowed some of Trump’s broadest tariffs to remain in place while it reviews a lower-court ruling that had blocked his “liberation day” levies on US trading partners.

The ruling extended an earlier temporary reprieve and will allow Trump to enact the measures as well as separate levies targeting Mexico, Canada, and China. The president has, however, already paused the wider “reciprocal” tariffs for 90 days.

Trump bans sales of chip design software to China

AI, china, ftc, Policy, syndication, Trump / Paul Patrick / May 29, 2025

Johnson, who heads China Strategies Group, a risk consultancy, said that China had successfully leveraged its stranglehold on rare earths to bring the US to the negotiating table in Geneva, which “left the Trump administration’s China hawks eager to demonstrate their export control weapons still have purchase.”

While it accounts for a relatively small share of the overall semiconductor industry, EDA software allows chip designers and manufacturers to develop and test the next generation of chips, making it a critical part in the supply chain.

Synopsys, Cadence Design Systems, and Siemens EDA—part of Siemens Digital Industries Software, a subsidiary of Germany’s Siemens AG—account for about 80 percent of China’s EDA market. Synopsys and Cadence did not immediately respond to requests for comment.

In fiscal year 2024, Synopsys reported almost $1 billion in China sales, roughly 16 percent of its revenue. Cadence said China accounted for $550 million or 12 percent of its revenue.

Synopsys shares fell 9.6 percent on Wednesday, while those of Cadence lost 10.7 percent.

Siemens said in a statement the EDA industry had been informed last Friday about new export controls. It said it had supported customers in China “for more than 150 years” and would “continue to work with our customers globally to mitigate the impact of these new restrictions while operating in compliance with applicable national export control regimes.”

In 2022, the Biden administration introduced restrictions on sales of the most sophisticated chip design software to China, but the companies continued to sell export control-compliant products to the country.

In his first term as president, Donald Trump banned China’s Huawei from using American EDA tools. Huawei is seen as an emerging competitor to Nvidia with its “Ascend” AI chips.

Nvidia chief executive Jensen Huang recently warned that successive attempts by American administrations to hamstring China’s AI ecosystem with export controls had failed.

Last year Synopsys entered into an agreement to buy Ansys, a US simulation software company, for $35 billion. The deal still requires approval from Chinese regulators. Ansys shares fell 5.3 percent on Wednesday.

On Wednesday the US Federal Trade Commission announced that both companies would need to divest certain software tools to receive its approval for the deal.

The export restrictions have encouraged Chinese competitors, with three leading EDA companies—Empyrean Technology, Primarius, and Semitronix—significantly growing their market share in recent years.

Shares of Empyrean, Primarius, and Semitronix rose more than 10 percent in early trading in China on Thursday.

China extends its reach into the Solar System with launch of asteroid mission

Tianwen-2’s mothership, with 11 scientific instruments, will commence the second phase of its mission after dropping off the asteroid specimens at Earth. The probe’s next journey will bring it near an enigma in the asteroid belt, named 311P/PanSTARRS, in the mid-2030s. This object is one in a rare class of objects known as active asteroids or main-belt comets, small worlds that have tails and comas like comets but loiter in orbits most commonly associated with asteroids. Tianwen-2 will be the first mission to see such an object up close.

Stepping into the Solar System

Until the last few years, China’s space program has primarily centered on the Moon as a destination for scientific exploration. The Moon remains the main target for China’s ambitions in space, with the goal of accomplishing a human lunar landing by 2030. But the country is looking farther afield, too.

With the Tianwen-1 mission in 2021, China became the second country to achieve a soft landing on Mars. After Tianwen-2, China will again go to Mars with the Tianwen-3 sample return mission, slated for launch in 2028.

Tianwen, which means “questions to heaven,” is the name given to China’s program of robotic Solar System exploration. Tianwen-3 has a chance to become the first mission to return pristine samples from Mars to Earth. At the same time, NASA’s plans for a Mars Sample Return mission are faltering.

China is looking at launching Tianwen-4 around 2029 to travel to Jupiter and enter orbit around Callisto, one of its four largest moons. In the 2030s, China’s roadmap includes a mission to return atmospheric samples from Venus to Earth, a Mars research station, and a probe to Neptune.

Meanwhile, NASA has sent spacecraft to study every planet in the Solar System and currently has spacecraft at or on the way to the Moon, Mars, Jupiter, a metal asteroid, and to interstellar space. Another US science mission, Dragonfly, is scheduled for launch in 2028 on a daring expedition to Saturn’s moon Titan.

But NASA’s science division is bracing for severe budget cuts proposed by President Donald Trump. In planetary science, the White House’s budget blueprint calls for canceling a joint US-European Mars Sample Return mission and several other projects, including the DAVINCI mission to Venus.

Do these Buddhist gods hint at the purpose of China’s super-secret satellites?

china, launch, long march 3b, long march 3c, long march rocket, military space, Science, Space / Paul Patrick / May 18, 2025

Mission patches are a decades-old tradition in spaceflight. They can range from the figurative to the abstract, prompting valuable insights or feeding confusion. Some are just plain weird.

Ars published a story a few months ago on spaceflight patches from NASA, SpaceX, Russia, and the NRO, the US government’s spy satellite agency, which is responsible for some of the most head-scratching mission logos.

Until recently, China’s entries in the realm of spaceflight patches often lacked the originality found in patches from the West. For example, a series of patches for China’s human spaceflight missions used a formulaic design with a circular shape and a mix of red and blue. The patch for China’s most recent Shenzhou crew to the country’s Tiangong space station last month finally broke the mold with a triangular shape after China’s human spaceflight agency put the patch up for a public vote.

But there’s a fascinating set of new patches Chinese officials released for a series of launches with top secret satellites over the last two months. These four patches depict Buddhist gods with a sense of artistry and sharp colors that stand apart from China’s previous spaceflight emblems, and perhaps—or perhaps not—they can tell us something about the nature of the missions they represent.

Guardians of the Dharma

The four patches show the Four Heavenly Kings, protector deities in Buddhism who guard against evil forces in the four cardinal directions, according to the Kyoto National Museum. The gods also shield the Dharma, the teachings of the Buddha, from external threats.

These gods have different names, but in China, they are known as Duōwén, Zēngzhǎng, Chíguó, and Guăngmù. Duōwén is the commander and the guardian of the north, the “one who listens to many teachings,” who is often depicted with an umbrella. Zēngzhǎng, guardian of the south, is a god of growth shown carrying a sword. The protector of the east is Chíguó, defender of the nation, who holds a stringed musical instrument. And guarding the west is Guăngmù, an all-seeing god usually depicted with a serpent.
