Europe postpones Mars mission over ExoMars rover issue and Coronavirus
The European Space Agency (ESA) announced that its ExoMars rover would not fly this year. The mission, a collaboration with the Russian Space Agency (Roscosmos), was set to launch this summer. However, the launch has been postponed to 2022 due to technical issues and the logistical impact due to the global Conoavirus outbreak.
“This is a very tough decision, but it’s, I’m sure, the right one,” ESA Director General Jan Wörner said during a news conference at ESA’s headquarters in Paris after consulting with the head of Roscosmos, Dmitry Rogozin. “The parties had to recognise that the final phase of ExoMars activities are compromised by the general aggravation of the epidemiological situation in European countries.”
“We agreed together it’s better to go for success than just to go for launch at this time,” Wörner said. “Although we are close to launch readiness, we cannot cut corners. Launching this year would mean sacrificing remaining essential tests.”
The ExoMars rover is Europe’s first Mars rover. Named after Rosalind Franklin, a British pioneer of DNA science, the robotic explorer will search for signs of life on the red planet’s surface. Wörner said the agency needs more time to troubleshoot issues with the spacecraft’s parachute system as well as precise electronics, so the delay is necessary.
Also, the recent coronavirus outbreak that’s spreading around the globe isn’t helping. So instead of rushing, the team is taking the next two years to conduct extensive testing and make sure they get it right.
“We have made a difficult but well-weighed decision to postpone the launch to 2022,” Rogozin said in a statement. “I am confident that the steps that we and our European colleagues are taking to ensure mission success will be justified and will unquestionably bring solely positive results for the mission implementation.”
The ExoMars rover is a follow-on to ESA’s ExoMars Orbiter mission, which reached the red planet in 2016. That mission consisted of two parts: the Trace Gas Orbiter (TGO) and the Schiaparelli lander, a technology demonstrator. Unfortunately, the Schiaparelli crash-landed during its descent to the Martian surface.
Landing a spacecraft on Mars is hard. The planet’s atmosphere is thinner than what we see on Earth, and as such its takes a combination of sophisticated tools, including heat shields, retrorockets, and even giant, inflatable airbags, to safely touch down on the surface.

If anyone of those techniques fails, the spacecraft will crash, which is what happened with Schiaparelli.
Despite being around for decades, parachutes are still pretty tricky, especially using them on another planet. ESA engineers have made many adjustments to the parachute system, but keep seeing the same result: they rip as soon as they deploy. Test, after test, the chutes failed. Engineers have tried reinforcing them with Teflon to make them slide out of their bags easier, but no luck.
ESA even tried to seek advice from NASA’s Jet Propulsion Laboratory, which has built every single rover on Mars and, unfortunately needs more time to collaborate on parachute design. Because there’s only a limited window of launch opportunity, ESA officials decided to make the tough call to postpone until the next Mars window opens in 2022.
Appreciate @esa and @roscosmos for making the tough decision to postpone @ESA_ExoMars to 2022. Launching & safely landing a spacecraft on Mars are extremely demanding and require many technologies & systems to function perfectly. Your work is inspiring everyone to do hard things. https://t.co/ttPzDyQJWa

The rover and its launcher, a Russian Proton rocket, are ready to go. The agency has more parachute tests in the works, including high-altitude drops.

Additionally, Wörner said the team discovered issues with the descent module’s electronic equipment, which are essential to the mission’s success. This piece of equipment controls functions like spacecraft power, propulsion, and even parachute control. It will take some time for the bugs to be fixed.
“Due to the troubleshooting of these anomalies at system level, the final version of the flight software has been delayed, and there is not enough time to fully test it before a 2020 launch and gain the confidence we need,” Wörner said.
You can technically launch to Mars anytime, but space agencies around the world choose specific windows that open every two years. During this time, Mars and Earth are in line, so that it takes less time and uses less fuel. In 2022, that window is open from August to October.
Once it reaches the Martian surface, the rover will study an ancient lake bed. It will scour the red planet’s surface in search of biosignatures, or signs of life.

SpaceX just launched a secret payload from California
SpaceX launched a classified Space Force mission from Vandenberg, revealing almost nothing about its payload.
SpaceX launched a classified Falcon 9 mission for the U.S. Space Force from Vandenberg Space Force Base on Saturday night, and the government released almost nothing about what was on board. The mission, designated USSF-366, lifted off from Space Launch Complex 4E with a window that opened at 9:52 p.m. ET and ran into the early hours of Sunday, according to SpaceX’s own mission page, which described the payload only as classified. SpaceX confirmed the launch on its X account and pointed viewers to a livestream that began roughly ten minutes before liftoff.

The lack of detail did not stop analysts from filling in the blanks. Independent tracking of the rocket’s stage drop zones matched the pattern SpaceX has used on previous Starlink Group 15 missions, according to reporting from Outer Space Today, which pointed to Starshield as the likely payload rather than a one off government satellite. Starshield is SpaceX’s national security product, a version of the Starlink satellite bus built to Pentagon specifications for earth observation, communications and hosted payloads. Unlike consumer Starlink, government agencies do not have to disclose what Starshield satellites are actually doing once they reach orbit.
USSF-366 is the latest entry in a steady flow of classified and semi classified work between SpaceX and the Space Force. The company picked up a $178.5 million task order in April to launch missile tracking satellites for the Space Development Agency, as Teslarati reported at the time, and followed that in July with a $1.6 billion award covering 18 more Falcon 9 missions from Vandenberg through the end of 2027, also detailed by Teslarati. Add those contracts up and SpaceX’s Pentagon business for 2026 alone tops $8 billion.
SpaceX scores another massive Pentagon deal to support military satellites
The Falcon 9 that flew Saturday landed back near the launch site, producing the sonic booms that have become routine for residents near Vandenberg. What is less routine is how little the public will likely ever learn about what the rocket carried. SpaceX and the Space Force have not confirmed the Starshield connection, and government satellite programs built on commercial buses rarely get identified beyond a mission number and a general orbit. For a company that live streams almost everything else it does, from Starship test flights to Optimus robot demos, USSF-366 is a reminder that some of SpaceX’s busiest work now happens entirely out of public view.

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
-
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.

SpaceX and Nvidia team up on Musk’s orbital AI bet
SpaceX revealed a new Nvidia satellite partnership, then Musk pledged an exclusive Nvidia hardware commitment.
SpaceX and Nvidia are now working together on the hardware that will power Musk’s orbital data center ambitions. SpaceX announced on X on Tuesday that it is partnering with Nvidia to design the compute payload for Starmind AI1, the first satellite in a planned constellation built to run AI workloads directly in orbit. Each Starmind satellite will carry Nvidia’s Rubin GPUs and Vera CPUs, according to the post, which included renderings of the payload design.
The announcement landed hours before SpaceX’s first earnings call as a public company, where Musk went further, saying the company has committed to building its AI infrastructure exclusively on Nvidia hardware. “We think the Vera Rubin architecture is the best architecture. We think it’s the best AI computer, and we greatly value our close cooperation and partnership on many levels with Nvidia,” Musk told investors on the call,. “So we’re exclusive to Nvidia.”
Musk said SpaceX plans to deploy Nvidia’s Vera Rubin NVL72 rackscale system, codenamed Kyber, both on the ground and in space. He set a target of 2 gigawatts of compute capacity online by the end of this year, scaling to roughly 10 gigawatts by the end of 2027.
SpaceX’s newest Starmind will make earth data centers obsolete
Starmind has been in development since Musk confirmed the name in June, following an xAI trademark filing that tipped off the project before SpaceX made it official. The idea is massive in scope and instead of moving data down to ground based servers, satellites equipped with onboard processors and large solar arrays would compute AI workloads in orbit and beam results back to Earth. SpaceX has already filed with the FCC for a constellation of up to one million satellites to support the effort, citing constant solar power and the absence of zoning restrictions as advantages over terrestrial data centers.
The Nvidia exclusivity marks a shift in tone from just two weeks ago, when Musk was busy knocking down a report that SpaceX had ordered $52 billion worth of Nvidia GPUs through Foxconn, calling it fake news at the time. The dollar figure in that rumor may have been wrong, but the underlying direction seems correct. SpaceX’s AI division already leases Colossus compute capacity to Anthropic and Google, and Tuesday’s earnings report showed AI revenue climbing sharply as those deals ramp up.
Nvidia shares rose roughly 3% in Tuesday trading on the news, while SpaceX stock climbed nearly 9% during the day before giving back gains after hours as investors digested the earnings report’s capital spending figures.
