SpaceX begins static Starhopper tests as Raptor engine arrives on schedule
SpaceX has officially begun static ground testing of Starhopper, a full-scale pathfinder Starship prototype meant to support an early series of Raptor-powered hop tests at SpaceX’s South Texas launch site. Simultaneously, the second completed Raptor engine arrived at the site on Monday, March 11th, confirming CEO Elon Musk’s March 8th tweets about the delivery.
While reasonably routine for any rocket test program, the first tanking test of Starhopper effectively marks the first time that SpaceX has begun tests with a more or less fully integrated Starship (previously BFS). Likely performed with liquid nitrogen instead of liquid oxygen/methane, the first few tanking tests will be used to determine the quality of the prototype’s stainless steel tanks – built en
In November 2016, SpaceX began propellant-loading tests of its first finished full-scale Starship (then Big Falcon Spaceship) hardware, a massive carbon composite liquid oxygen tank stretching 12 m (~40 ft) in diameter. Over the course of 2017, SpaceX transitioned from liquid nitrogen to liquid oxygen and ultimately conducted one final burst-test in which the composite tank was pressurized until it exploded, ending full-scale BFR composite testing with a bang. Within 6-12 months, Musk had come to the conclusion that a stainless steel BFR would ultimately be a superior path forward for the rocket and spaceship and attempted (apparently successfully) to get his team of R&D engineers on board with such a radical change so late in the development phase.
Despite the fact that that radical design departure may have occurred as few as 6-8 months ago, SpaceX engineers and technicians have accomplished an extremely rapid development program that will – in part – culminate in the hopefully successful hop testing of Starhopper, the first Starship prototype. While more of a rough testbed than an actual representation of the hardware and structures that will be required for a reusable orbital-class Starship, Starhopper has at least acted as a crash course (either technically or organizationally) on fabricating and assembling stainless steel aerospace structures, a material largely foreign to SpaceX flight hardware prior to late 2018.
Although the early vehicle was less than encouraging, as was the demise of its nosecone as a consequence of improper planning and/or bad workmanship, Starhopper as it now stands might actually be flightworthy in the context of suborbital, subsonic hop tests. Powered by the same or similar Raptors that would power orbital prototypes, Starhopper’s hop tests would optimally provide a wealth of experience and engineering data for both building 9 meter/30 foot-diameter stainless steel rocket sections and operating full-scale Raptor engine(s) in actual flight configurations. Extensive testing with Raptor will help to ensure that the fit and finish of the new engine’s flight-grade avionics and hardware are up to the challenge of safe, reliable, and gentle operations for a nominally crew-rated launch vehicle and spacecraft.
Around two days after Starhopper was briskly transported from its build site to SpaceX’s brand new launch facility, local Twitter account @SPadre (short for South Padre Island) posted a video of tanking test that occurred on March 11th, capturing the sound of venting as the liquid involved turned to gas inside its propellant tank(s). The fact alone that the person behind the camera was allowed to be where they were during the test all but guarantees that this first test was performed with an inert liquid, most likely liquid nitrogen given a massive delivery that occurred the day before (March 10th). In no conceivable world would SpaceX or local law enforcement willingly allow for Starhopper to be loaded – for the first time ever – with even a partial load of liquid methane or liquid oxygen with bystanders barely a few hundred feet distant.
When SpaceX gets to the point that they are confident enough in the structural integrity of Starhopper to begin wet dress rehearsals and tests with actual propellant, it’s a safe bet that the company will cooperate with local law enforcement to block off the lone access road to a distance of at least 1-2 miles, if not more. It’s unclear if local homeowners and residents will be forced to vacate the adjacent Boca Chica Village during testing, but chances are good that nobody will be within several thousand feet of Starhopper when those propellant loading tests begin, let alone actual static fire activity once Raptor(s) are installed.
According to an official SpaceX statement on the progress, propellant load tests and static fires could begin “in the days ahead”, although the spokesperson was under the impression that those tests – as well as initial hop tests – “[would] not be visible from offsite”. Unless SpaceX plans to draw a keep-out zone with a radius of multiple miles, interested observers will almost certainly be able to get close enough to at least catch a glimpse of Starhopper, but the statement still offers an idea of just how focused the company will be on safety during these early tests.

SpaceX brings four astronauts home after 8 months in space, and the return was flawless
SpaceX Crew Dragon Freedom returned four Crew-12 astronauts home after 237 days aboard the station.
Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.
NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.
The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.
SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.
Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.
The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.
With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.

Elon Musk shuts down talk of TSMC taking over Terafab
Musk says Tesla and SpaceX will build and run Terafab, with TSMC limited to renting.
Elon Musk has drawn a firm line around who will be in charge of Terafab, the giant chip factory Tesla and SpaceX are planning in Texas.
Musk replied to a post on X arguing that Taiwan Semiconductor Manufacturing Company (TSMC) would most likely end up owning and operating the plant. “No, we will build and run the fab. Let there be ZERO doubt about that,” Musk wrote. “Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.”
In plain terms, a sublease means TSMC could rent a section of the complex to make chips, similar to a tenant renting one floor of an office tower. The building, the equipment decisions and the daily operation would stay with Tesla and SpaceX.
@herbertong @thejefflutz No, we will build and run the fab. Let there be ZERO doubt about that.
Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.
— Elon Musk (@elonmusk) October 7, 2026
The comment shuts down speculation that started last week. On October 2, tech journalist Tim Culpan reported that TSMC was exploring ways to help run Terafab’s factories. Musk responded the next day that it was “just discussions, but something may come of it,” as Teslarati reported at the time. That left room for a scenario where the world’s largest contract chipmaker took the wheel. Musk’s latest post closes that door.
Some background helps explain why this matters. Tesla designs its own AI chips today but pays outside companies like TSMC and Samsung to manufacture them. Musk unveiled Terafab in March as a joint project between Tesla, SpaceX and xAI, arguing that existing suppliers cannot expand fast enough to meet his companies’ future demand. The goal is to produce enough chips each year to supply one terawatt of computing power, roughly 50 times what the entire global AI chip industry produces now.
Those chips are meant for Tesla’s Optimus humanoid robots, the Cybercab and Full Self-Driving computers, along with chips for SpaceX’s planned data centers in orbit. Owning the factory means Musk’s companies would not have to compete with every other chip customer for time on someone else’s production lines.
Intel is still part of the picture. The company signed on in April to help design, build and package chips for the project, and CEO Lip-Bu Tan told Bloomberg this week that Intel will keep working on Terafab despite the TSMC chatter.
The project moved from concept to construction planning over the summer. In August, SpaceX confirmed the Grimes County site about an hour from Houston, sent the county a $10 million payment under its tax abatement deal and said civil work would begin shortly. The first phase carries a $16.8 billion price tag, and total spending across all phases could reach as much as $119 billion.
TSMC chairman C.C. Wei has said a new fab typically takes two to three years to build and another one to two years to reach full output. Tesla and SpaceX have never run one, which is why TSMC’s expertise drew so much attention. Musk’s answer suggests he would rather learn that process in house than hand control of a project this central to Tesla’s robotics and autonomy plans to an outside company.
Terafab Texas will be the largest and most valuable building on Earth by far.
And it will be stunningly beautiful. https://t.co/4NweOqTL7y

Trump to hand Elon Musk a top honor that traces back to JFK
Trump will award Elon Musk the National Medal of Science at Thursday’s White House summit.
Elon Musk is set to receive the highest honor the U.S. government gives to scientists and engineers.
President Donald Trump will present Musk with the National Medal of Science on Thursday at the White House’s Science: A New Golden Age Summit, Fox News Digital first reported on Wednesday. Google cofounder Sergey Brin, Nvidia CEO Jensen Huang and AMD CEO Lisa Su will receive the same medal, while Dell Technologies CEO Michael Dell and Microsoft CEO Satya Nadella will receive the National Medal of Technology and Innovation. A White House official later confirmed the list to Reuters.
“The Trump administration is grateful for the contributions of these incredible leaders in science and technology. These recipients are helping ensure America keeps leading the world in innovation,” White House spokesperson Liz Huston told Fox News.
FIRST ON FOX: Trump will award Elon Musk the National Medal of Science at the White House Thursday.
Sergey Brin, Jensen Huang and Lisa Su will also receive the science medal, while Michael Dell and Satya Nadella will receive the technology medal.
It marks Trump’s first time presenting the awards across either administration.

It will be the first time Trump has presented either medal in his two terms. Congress created the National Medal of Science in 1959, and the National Science Foundation, which administers it, says 529 scientists and engineers have received it since. A presidential committee reviews nominees, but the president makes the final call.
Thursday’s group of medalists run or founded companies, and three of them sit at the center of the Super Intelligence hardware race that Musk competes in. Huang’s Nvidia supplies the GB300 chips filling SpaceX’s Colossus 2 cluster, while Su’s AMD is Nvidia’s biggest rival in data center GPUs.
Worth noting that Trump’s uncle, MIT physicist John G. Trump, received the National Medal of Science from President Ronald Reagan for his work on ionizing radiation and its uses in medicine and industry.
The Pentagon taps Elon Musk to design the battlefield of the future
For Musk, the medal is the latest sign of how far his relationship with Trump has come since their 2025 split over the “Big Beautiful Bill” and his exit from DOGE. Last week, he sat at Trump’s left during a White House lunch where AI executives signed a voluntary safety accord, and Defense Secretary Pete Hegseth named him to help lead the Pentagon’s Project Meridian study on the future of warfare. Musk has also adopted the administration’s new vocabulary, saying on Sunday that SpaceXAI will be renamed SpaceXSI after Trump ordered federal agencies to replace “artificial intelligence” with “super intelligence.”
Musk has collected science honors before, including the Stephen Hawking Medal for Science Communication in 2019.
