SpaceX installs new Starship on static fire test stand
SpaceX may be focused on preparing Starship S24 and Super Heavy Booster 7 for their potentially imminent orbital launch debut, but the rest of the company’s Starship factory isn’t just sitting around.
The laser focus on carefully testing Ship 24 and Booster 7 may have limited the effectiveness of Starbase rocket production, but the factory has continued to produce new ships and boosters. SpaceX has even conducted some limiting testing of a pair of prototypes meant to follow in the footsteps of S24 and B7. In mid-January, that process entered a new and more active phase as SpaceX transported Starship S25 from the factory to the launch pad.
The trip is not Ship 25’s first. Starship S25 first headed to SpaceX’s South Texas launch and test facilities on October 19th, 2022, shortly after the vehicle was fully assembled. Around three weeks of testing followed, and now Ship 25 is back for more.

Ship 25
The first round of tests was thorough and put Ship 25 through a pneumatic proof test, multiple cryogenic proof tests, and likely a few simulated thrust tests using six hydraulic rams.
“Ship 25 was removed from SpaceX’s other Starship test stand on November 8th, it was rolled back to Starbase’s Starship factory. Ship 25 first rolled to the launch site on October 19th and has since completed four visible tests. On October 28th, Ship 25 survived a pneumatic proof test that showed that its tanks were leak-free and capable of surviving flight pressures (roughly 6-8.5 bar or 90-125 psi). Three cryogenic proof tests followed on November 1st, 2nd, and 7th. The first cryoproof was likely just that – a test that pressurized Ship 25’s tanks and filled them with cryogenic liquid nitrogen (LN2) or a combination of liquid oxygen and LN2.
The next two tests likely took advantage of the customized test stand, which has been semi-permanently outfitted with a set of hydraulic rams that allow SpaceX to simulate the thrust of six Raptor engines while Starship’s structures are chilled to cryogenic temperatures and loaded with roughly 1000 tons (~2.2M lb) of cryogenic fluids. If a Starship can survive those stresses on the ground, the assumption is that it will likely survive similar stresses in flight.”

As usual, SpaceX didn’t comment on the development or indicate how that initial proof testing had gone, but Ship 25’s January 14th, 2023 return to the launch site all but guaranteed that that testing had gone more or less according to plan. On January 17th, SpaceX lifted Ship 25 onto Starbase’s only Starship static fire test stand, further confirming that Ship 25 proof testing went to plan.
Soon after its November 2022 return to Starbase’s build site, six Raptor engines were moved into the High Bay and installed on Ship 25. The Starship’s aft was then likely buttoned up with a heat shield before it headed to the test site to begin its static fire test campaign. That campaign could tell us a lot about the status of Starship prototypes. To date, only two Ships have completed full six-Raptor static fire tests, and both took days, weeks, or months to build up to those six-engine milestones with multiple smaller tests. If Ship 25 were to skip those preliminary tests and immediately conduct a six-engine static fire, it would be a sign that SpaceX is significantly more confident in the current Starship design.
Booster 9
Ship 25 is believed to be paired with Super Heavy Booster 9, which recently finished its own round of proof tests. About two months behind Ship 25, Booster 9 rolled out of its Starbase assembly bay and headed to the launch site on December 15th, 2022. The Super Heavy prototype ultimately completed two partial cryogenic proof tests on December 21st and 29th, during which it was likely loaded with around a thousand tons of liquid nitrogen to simulate explosive liquid oxygen and methane propellant. Booster 9 then returned to Starbase’s factory on January 10th, 2023.
Assuming those tests went well, Raptor engine installation could begin at any moment. However, thanks to significant design changes and upgrades present on Booster 9, outfitting and testing this Super Heavy could take longer than usual. Many smaller changes are present, but the most significant by far is the addition of an upgraded version of Raptor. The engine’s combustion-related hardware is likely the same as the Raptor V2 engines present on Booster 7, Ship 24, and Ship 25. But the hardware used to steer each engine – called thrust vector control (TVC) – has been completely changed.
Instead of using a complex web of plumbing and hydraulic power units bolted to the side of Super Heavy, Booster 9’s 13 central Raptors will be electrically steered. That has allowed SpaceX to remove those power units (streamlining Booster 9’s exterior) and reduce the already rats nest of plumbing required to fuel, control, power, and steer dozens of high-performance rocket engines on one booster. SpaceX has been testing electric Raptor TVC for months at its McGregor, Texas development facilities, but it’s unclear if the new technology has progressed to the point that 13 upgraded engines are ready to be installed on Booster 9. In the meantime, SpaceX may install Booster 9’s fixed outer ring of 20 Raptor V2 engines – none of which gimbal or need new electric TVC hardware.
Once all 33 engines are installed, it’s likely that Booster 9 will be thoroughly tested to ensure that all 13 electrically-steered engines work well together before, during, and after numerous static fire tests. SpaceX will also need to verify that the batteries likely powering those new systems function as expected. During the peak stresses they will likely experience, the electric TVC could need to rapidly redirect more than 3000 tons (~6.6 million lbf) of thrust multiple times per second. The peak power required from Super Heavy’s batteries will likely be immense as a result.
For now, the start of Super Heavy B9’s own static fire test campaign could be months away and will have to wait until Starbase’s only orbital launch mount – currently occupied by Booster 7, Ship 24, and Starship’s first orbital launch campaign – is vacated. With that orbital launch debut unlikely to happen before March 2023, Booster 9 has plenty of time to relax inside Starbase’s Wide Bay while Ship 25 begins static fire testing at a separate stand.

Tesla eyes supply partners for Optimus mass production
Tesla certified three Chinese suppliers for Optimus mass production, signaling its robot timeline is accelerating.
Tesla’s robotics team traveled to Ningbo, in China’s Zhejiang province, on September 16 and spent the following day auditing component suppliers for Optimus, according to a Bloomberg report cited by RobotAIGeek. The visit moved three manufacturers from provisional status to certified mass production partners: Tuopu Group, which handles actuators and chassis components, Ningbo Joyson Electronic, a sensor supplier, and Zhejiang Sanhua Intelligent Controls, which builds thermal management systems. All three already supply parts to Tesla’s electric vehicles, and the audit reportedly came with fresh orders that supply chain reports put at an initial batch of roughly 5,000 units.
Tuopu, Joyson, and Sanhua built their manufacturing base serving the automotive industry, where tolerances and volume requirements are already close to what a mass produced humanoid robot demands. Sanhua in particular has history here. Teslarati reported last October that the company had received a roughly $685 million order for linear actuators tied to Optimus, a volume industry watchers estimated could cover around 180,000 robots once production ramped.
Supply chain reports tied to this week’s audit put Tesla’s near term production goal at about 1,000 Optimus units a week by late September, rising to 2,000 to 2,500 units a week by the end of the year. That pace would put real weight behind the timeline Tesla has been building toward since May, when it wound down Model S and Model X production at Fremont to convert that floor space into a dedicated Optimus line targeting one million units annually. JPMorgan analysts who toured the factory in August confirmed the conversion took roughly four months, a pace Musk has called unprecedented for a facility that size.
New drone video shows Tesla’s Optimus Factory reaching a turning point
Fremont is only the first phase. A second, larger Optimus plant is rising at Gigafactory Texas, where drone footage shared by Joe Tegtmeyer last week showed the structural steel nearing completion on the north end of the building. Tesla has said that facility is meant to eventually support production of up to 10 million units a year, though volume output there is not expected before 2027.
Commercial sales of Optimus are still targeted for the second half of 2027, but production is expected to start well before then. JPMorgan analyst Rajat Gupta has said Tesla’s “Optimus Academy” program, which uses early units to collect real world training data inside Tesla’s own facilities, is expected to be running later this year. Bloomberg Intelligence analyst Ian Ma described the Ningbo audits as “a positive commercialization signal for China’s humanoid supply chain,” noting that sentiment could improve further if the visit leads to confirmed supplier nominations and larger orders. The Solactive China Humanoid Robotics Index rose about 1.4% on the news, though it remains down roughly 30% for the year.

Elon Musk’s next Uranium in Uranus merch is Boring Company’s weirdest tease yet
Elon Musk teased a glowing new Boring Company merch idea, complete with a Geiger counter.
Elon Musk teased the next piece of Boring Company merchandise on X Saturday, and it is exactly as unserious as fans of the company’s product history have come to expect. “The next @boringcompany merch will put Uranium in Uranus,” Musk wrote in a thread posted early Saturday morning. He followed up by explaining that the item would glow in the dark, “because otherwise how could you find it,” and that a Geiger counter would be sold separately as “an optional strap-on.”
Musk closed the thread with a line that doubles as a mission statement for the tunneling company’s merchandise arm: “It’s not easy coming up with something that is both outrageously unsellable and yet extremely popular.”
The Boring Company has built a small but consistent side business out of novelty items that start as jokes and end up selling out. The company’s Not-a-Flamethrower raised roughly $10 million in a few days back in 2018, moving all 20,000 units it produced. Its Burnt Hair perfume, priced around $100 a bottle, sold out fast enough that scalpers were flipping units on eBay for ten times the retail price. Boring Bricks, made from tunneling spoil, followed the same playbook of teasing a product on X months before it became real.
Musk has not said what the actual item will be, only that it involves uranium and glows in the dark. Given the pattern, that vagueness is probably intentional. Past merch announcements have started as one-line jokes and taken weeks or months to turn into an actual product listing on the company’s site, and there is no guarantee this one follows through at all.
The timing lines up with a period of real momentum for the Boring Company outside of the joke merchandise. The company said last week it plans to double the number of operational stations on its Vegas Loop by the end of the year, a target tied to a hiring push for drivers and operations managers. Prufrock-5, one of the company’s tunnel boring machines, also just wrapped a test tunnel in Bastrop, Texas, and is expected to relaunch on its next assignment in November.
Whether the uranium joke turns into an actual product remains to be seen. Musk’s post did not include a price, a shipping date, or even a name for the item, which has historically meant a Boring Company website page goes up quietly, password protected, sometime before an announcement.

NASA taps SpaceX for more astronaut missions as Boeing Starliner remains grounded
NASA just gave SpaceX a $946 million contract for three more astronaut missions through 2030.
NASA has awarded SpaceX a $946 million contract modification covering three more astronaut missions to the International Space Station, according to an announcement the agency published Friday. The award adds Crew-15, Crew-16, and Crew-17 to SpaceX’s existing Commercial Crew Transportation Capability contract, bringing the agreement’s total value to $5.92 billion across 17 flights.
SpaceX confirmed the award on X, writing that it was excited for Falcon 9 and Dragon to launch NASA’s Crew-15, 16, and 17 missions to the Space Station from Florida. The new missions cover ground, launch, in orbit, and return operations, along with cargo transport and a lifeboat capability while docked at the station, and the period of performance runs through 2030.

The award follows a notice of intent NASA issued in May, when the agency first signaled it would purchase up to six additional post certification missions from SpaceX. Teslarati covered that filing at the time, noting NASA cited technical issues and schedule delays encountered by Boeing as a driving factor. Friday’s contract modification locks in three of those six missions, with the remaining three left open for NASA to award later, potentially to Boeing if Starliner clears certification.
Boeing’s CST-100 Starliner has still not flown an operational crew rotation mission for NASA. The spacecraft’s most recent crewed test flight in 2024 ended without the astronauts returning aboard Starliner, and the company has spent the time since working through thruster problems. SpaceX President Gwynne Shotwell said this week that SpaceX is not retiring Crew Dragon today, for sure, while stopping short of committing to fly it past 2030.
Crew-12 is currently docked at the space station, and NASA has said Crew-13 is targeting a launch in the coming weeks. The newly awarded Crew-15 through Crew-17 missions extend SpaceX’s role as NASA’s primary way of getting astronauts to and from orbit well into the back half of the decade, regardless of what happens with Starliner or Starship in the meantime.
