SpaceX’s Starship, Starhopper prototypes continue slow and steady progress

Published

on

The last few weeks of SpaceX’s work on Starship and Starhopper prototypes has been marked by less visible progress relative to the past few months. The changes that are visible, however, confirm that its Boca Chica engineers are working around the clock to complete the first orbital Starship prototype.

At the same time, it appears that SpaceX’s South Texas facilities are preparing for a rapid period of expansion and build-up. New work around the ad-hoc Starhopper pad has recently begun, while construction of a second concrete jig for concurrent prototype fabrication and what will likely be a more permanent hangar and control facility are also ramping up. Things have been quiet news-wise for SpaceX’s McGregor and Hawthorne facilities but there is reason to believe that Raptor production and testing is going smoothly.

Starship Alpha

The most obvious visible progress made in April is centers around SpaceX’s first orbital Starship prototype, soon to begin its third month of active construction. As of mid-March, the shells of two large steel barrel sections – together about 18 m (60 ft) tall – were fully erected at the build site, with a handful of other sections in various states of welding. The height of those two cylinders has remained unchanged since then but it’s safe to assume that a ton of work has been going on inside them, invisible to anyone viewing from public perspectives since drones were effectively banned in March. In other words, the two pieces – most likely the barrel sections of Starship’s liquid methane and liquid oxygen (LOX) tanks – are likely being carefully transformed into actual propellant tanks.

There is also a good reason for their height differential: the larger (LOX) section is almost exactly a third larger than the small section (methane) in part because of the physical reality that Starship will need almost exactly 33% more LOX than methane by volume. Large propellant tanks – particularly those meant for cryogenic fluids and spaceflight applications – are often quite complex, with the vast majority of that complexity happening under the hood. The above render was made while SpaceX was still planning on carbon fiber tanks and also appears to be significantly simplified, but it still offers a small look at some of that complexity.

Aside from successfully completing thousands of welds throughout the assembly, a lot of the effort of building an advanced tank is put into plumbing – both internal and external – needed to load, unload, pressurize, depressurize, and generally manage cryogenic (i.e. super cold) liquid propellant. SpaceX decided to utilize a partial balloon tank design to keep the steel skins of its stainless steel Starship and Super Heavy as thin as possible, adding yet another level of internal work due to the need for stringers and longerons on top of baffles and hardware to mount COPVs or header tanks.

Adding further complexity to the internal structure of Starship is the presence of major aerodynamic surfaces and landing legs, both of which will need to survive extreme stresses if they are to function as intended. Those structures must be aerodynamically streamlined and attach to the outside of Starship’s hull, likely requiring significant structural reinforcements both inside the spacecraft’s nose and rearmost propellant tank.

Super Heavy?

SpaceX began construction of a second concrete fabrication jig just a handful of days ago. Effectively a copy of a jig occupied with the larger of the two barrel sections of the orbital Starship prototype, the simple structure acts as a mount and includes a large door that allows scissor lifts to get inside the steel structure. The new jig is being built directly adjacent to Starship’s smaller barrel section, suggesting that it could simply be a way to concurrently work on both the LOX and methane tanks. Given the inherent simplicity of a concrete jig, it could also end up being used to support the simultaneous assembly and integration of the first Super Heavy booster prototype.

Back in December 2018, SpaceX CEO Elon Musk indicated that the first Super Heavy prototype would start production in “spring” (i.e. NET April 2019). Musk has also indicated that Starship and Super Heavy will be simultaneously built both in Boca Chica, Texas and Cape Canaveral, Florida. In general, SpaceX is clearly beginning another round of expansion and improvement for its Boca Chica facilities, including the new concrete jig and an entirely new building on the same plot of land.

Starhopper

Last but not least is SpaceX’s Starhopper prototype. After completing an inaugural round of multiple wet dress rehearsals (WDRs) and two Raptor static fires/hops, SpaceX technicians removed the vehicle’s lone Raptor engine on April 8th. Starhopper has remained more or less inactive in the last two weeks, aside from some work going on inside the vehicle (per the open access hatch).

Without a Raptor engine, there is admittedly not a whole lot that SpaceX can do with Starhopper, aside from additional WDRs if the first handful of tests were not enough. Instead, some minor work has been going on around the Hopper’s ad hoc pad, mainly taking the appearance of dirtmoving. Without aerial views, its hard to tell what exactly is taking shape, but it’s safe to say that Starhopper is simply waiting for additional Raptors to be produced, tested, and delivered to Boca Chica. Once more Raptors are ready, it’s understood that SpaceX will move into multi-engine (likely 3+) hop tests, perhaps loosing Starhopper from its tethers.

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.

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.

Elon Musk teases TSMC as potential Terafab partner

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.

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.

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.
