SpaceX and NASA are working together to make sure they’re ready to start flying crews to the space station. Two astronauts, Doug Hurley and Bob Behnken are preparing to launch on a Crew Dragon capsule, with a scheduled date of mid to late May for the historic launch.

As the world deals with the coronavirus, essential personnel at both NASA and SpaceX are continuing to progress to a crew flight. Since the final shuttle flight in 2011, NASA and other space agencies around the world have been forced to rely on Russian rockets as their sole means of transporting astronauts to and from space.

That will change with the next flight of SpaceX’s Crew Dragon capsule. The gumdrop-shaped spacecraft is set to carry Behnken and Hurley to the orbiting outpost. The length of their stay is still to be determined, but training efforts suggest that it will be longer than the original planned flight.

To that end, the duo has been working with NASA and SpaceX to practice day of launch procedures. On March 19 and 20, teams gathered in Firing Room 4 at NASA’s Kennedy Space Center to complete a series of full missions, from launch to landing. After the retirement of the shuttle fleet, NASA turned to the private sector to find its next generation of space taxi.

The space agency selected SpaceX and Boeing in 2014 to each build a spacecraft capable of ferrying crew to and from the space station. SpaceX’s Crew Dragon was the first to complete an uncrewed flight test, where the vehicle proved it could dock and undock itself from the space station. That test was a huge success and was followed on by a picture-perfect test of the Crew Dragon’s onboard escape system earlier this year.

Following the inflight abort test, all SpaceX needed to do was complete a few more tests of its Mark 3 parachute before NASA gave the all-clear to launch. But the company ran into a snag when it experienced two incidents back-to-back – the loss of a mock Dragon used for parachute testing and an unrelated in-flight rocket engine failure.

But SpaceX and NASA’s plans appear unphased, and the duo are working full steam ahead to the tentative May launch deadline. Key flight control teams stationed at their launch posts at NASA’s Kennedy Space Center, Johnson Space Center and SpaceX HQ have simulated the different phases of launch. In contrast, the astronauts have practiced launch procedures from their Crew Dragon simulator.

“The simulations were a great opportunity to practice procedures and to coordinate decision-making for the mission management team, especially with respect to weather,” Michael Hess, manager of operations integration for NASA’s commercial crew program said in a news statement.

“Simulation supervisors do a great job at picking cases that really make the team think and discuss,” he added.

During the most recent simulations, teams ran through an entire mission, from prelaunch countdown to ascent and docking with the station while previous tests ran through timelines from hatch closure to undocking from the space station as well as practiced free-flight in preparation for re-entry and splashdown.

The countdown is on as the Crew Dragon capsule undergoes its final testing and preparations at SpaceX facilities at Cape Canaveral Air Force Station in Florida. Once crew training and flight readiness reviews are complete, the spacecraft will be attached to its launcher: a shiny, new Falcon 9 booster.

If all goes according to plan, in late May, Bob Behnken and Doug Hurley will strap in and blast off the space station. There they will join fellow NASA astronaut, Chris Cassidy, who launches to the space station on April 9.

To ensure the mission gets off without a hitch, NASA and SpaceX are working closely and adhering to CDC guidelines to ensure teams stay safe and healthy. All non-essential employees are working from home, and the number of people coming in contact with the astronauts is minimal.

“The Space Station Program is looking forward to [having] another way to rotate crews to station to perform science and experiments to benefit all,” Hess said.

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.

SpaceX has solved Starship’s biggest challenge, Elon Musk says

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.

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.

Published

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.
