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.

Starship S25 rolled out for the first time almost three months ago.

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.

NASA’s first human outpost on the Moon starts now – SpaceX on deck

NASA named the rovers, landers, and vendors that will build America’s first Moon Base.

Published

NASA has laid out its most detailed Moon Base plan to date, describing a permanent outpost near the Moon’s south pole that the agency intends to build over the coming decade as a direct stepping stone to Mars. “The Moon Base will be America’s and humanity’s first outpost on another celestial world,” NASA Administrator Jared Isaacman said, adding that every mission crewed and uncrewed “will be a learning opportunity as we return to the lunar surface, build the infrastructure to stay, and master the skills required to live and operate in one of the most demanding and dangerous environments imaginable.”

The plan is structured in three phases involving both uncrewed and crewed missions to deliver equipment, vehicles, and infrastructure to the surface, with the first three moon base missions targeted to launch before the end of 2026.

Moon Base I, targeting fall 2026, will use Blue Origin’s Blue Moon Mark 1 lander to deliver scientific instruments to the Shackleton Connecting Ridge, the same region where Artemis astronauts will land. Moon Base II will send Astrobotic’s Griffin lander carrying more than 1,100 pounds of cargo including Astrolab’s FLIP rover to begin developing mobility systems on the surface. Moon Base III will carry the Lunar Vertex science mission on Intuitive Machines’ Nova-C Trinity lander to study lunar swirls near the south pole, with ESA and Korean science payloads aboard.

Elon Musk pivots SpaceX plans to Moon base before Mars

 

On the rover side, NASA awarded Astrolab $219 million and Lunar Outpost $220 million to build the first phase of Lunar Terrain Vehicles, with both rovers targeted for deployment to the lunar surface by 2028. Astrolab’s crewed rover weighs roughly 2,000 pounds and can reach over 6 mph. Lunar Outpost’s Pegasus rover can operate autonomously or via remote control at over 9 mph. Blue Origin separately received $188 million with an option worth $280.4 million to deliver cargo landers for rover transport.

NASA also confirmed that MoonFall, a mission deploying four survey drones to scout Artemis landing sites, has selected Firefly Aerospace to build the transport spacecraft, with a 2028 launch target.

SpaceX sits at the center of that commercial layer. SpaceX holds the NASA Human Landing System contract for the Starship-derived lander that will put astronauts on the surface under Artemis IV, currently targeting 2028. Before that can happen, SpaceX must demonstrate in-orbit propellant transfer at scale, a process requiring multiple Starship tanker launches to fuel a single mission. Water ice at the lunar south pole is central to the base’s long-term viability, as it can be converted into drinking water, breathable oxygen, and rocket fuel, directly reducing dependence on Earth resupply. That resource loop becomes far more practical if Starship can land and be refueled on or near the Moon itself.

Elon Musk has publicly stated that Starship V3, which recently completed its first flight, should be capable enough for initial Mars missions. The Moon Base plan announced Tuesday is the infrastructure layer that connects everything between those two ambitions, and SpaceX is the only American company currently contracted to build the rocket that gets humans to either destination.

Tesla patent reveals strategy for solving major Full Self-Driving, Optimus issue

Published

A new Tesla patent that has been granted to the company this week has revealed a potential strategy for solving a major issue that could impact both the Full Self-Driving suite and Optimus.

The patent, which is No. 12,636,684, describes a “Lens Cleaning System,” and was submitted by Tesla in May 2025.

The language in the patent details a lens cleaning system that can dispense fluid and wipe it away with a wiper assembly.

This would effectively clean any debris that would potentially impact the visibility of the cameras on Tesla automobiles or Optimus’s camera eyes. Perhaps the most pertinent example is through the Full Self-Driving suite, as debris that can accumulate on the vehicle’s exterior cameras can impact the suite’s ability to operate effectively.

This requires a remedy through manual cleaning, but this patent hints that Tesla could be planning to implement this new technology on its upcoming vehicles.

Interestingly, we have started to see it on some Robotaxi vehicles, and it will likely be included in the Cybercab, especially as that vehicle will enable full autonomy.

Back in January, the first Model Y Robotaxi units were spotted with camera washers on the side repeaters, as the video below shows fluid squirting and rinsing off any debris that is limiting visibility.

This hardware patent does bring up an interesting question for those of us who own Teslas with AI4 and have been told that our cars will one day be capable of full autonomy: Will this washer be available as a retrofit on already-built cars?

Perhaps the “Lens Cleaning System” patent is a good look at one way Tesla plans to combat one of the most obvious issues of autonomy that utilizes a camera-based system. For Optimus, it could be less needed as it could be manually cleaned by owners. For cars, it seems like a bigger necessity, especially as autonomy nears and Tesla gets close to launching a feature-complete FSD suite.

SpaceX’s Starlink product has just gotten its latest airline adoptee, and the move marks the successful partnership of three of the “Big Four” U.S. airlines.

American Airlines announced on Tuesday that it would utilize Starlink in more than 500 narrowbody aircraft beginning in the first quarter of 2027. These include the Airbus aircraft in its fleet, including the new A321XLR and A321neo.

With the new partnership with American Airlines, Starlink is now present on three of the largest airlines in the country: American, United, and Southwest.

Starlink gets its latest airline adoptee for stable and reliable internet access

Starlink’s VP of Enterprise Sales, Jason Fritch, said:

“We are proud to bring Starlink on board American Airlines, delivering fast and reliable internet to passengers and crew. Whether traveling for leisure or business, Starlink enables a fully connected experience gate to gate, making every flight smoother and more enjoyable.”

Additionally, American Airlines Chief Customer Officer, Heather Garboden, said:

“As a premium global airline, we are continuously seeking out world-class partners like Starlink to deliver what our customers need and want. The addition of Starlink solidifies American as a leading airline in keeping passengers connected in flight.”

Starlink has been on a tear over the past year, as it has continued to be adopted by a wide variety of airlines as a more consistent and reliable way to provide WiFi to its passengers. It has already gained a great reputation among residential users, but its biggest commercial application appears to be how it is being used in the air.

The only airline of the Big Four not to adopt Starlink thus far is Delta, which chose to opt for the alternative, which is Amazon Leo. CEO Ed Bastian said to Bloomberg that Delta chose Amazon’s product over Starlink’s because “the opportunities, in terms of the improved bandwidth with a much lower price point than what we’ve ever seen from Starlink, will make a big difference.”

Delta will not start installing Amazon Leo until 2028.

“Of course, we expect Starlink will be warning people that we’re going to go with an inferior product,” Bastian said. “But I’m not too worried about partnering with Amazon.”
