SpaceX shuffles Starships, gears up for more Super Heavy static fires

Published

on

SpaceX is busy preparing for the orbital launch debut its next-generation Starship rocket, but the company’s South Texas rocket factory is also working around the clock to prepare several more sets of ships and boosters for the flight testing that will follow.

That was more obvious than usual on November 8th, when SpaceX made moves to prepare both of its finished Starships for new phases of testing. SpaceX kicked off the busy day by removing Starship S25 – a newer prototype that arrived at the launch site just three weeks prior – a stand dedicated to proof testing ships. Three hours later, after spending three of the last four weeks sitting on top of Super Heavy Booster 7, Starship S24 was ‘destacked’ (lifted off of B7 and lowered onto a stand on the ground) in the early afternoon.

Booster 7, Ship 24, and Ship 25 have all been busy since mid-October. SpaceX stacked Booster 7 and Ship 24 for the first time on October 11th and then attempted to test the fully-stacked rocket on October 13th. By some accounts, although almost nothing was visible to the public, the first full-stack test may have gone poorly, potentially even endangering pad technicians that approached the rocket to troubleshoot. On October 16th, SpaceX fully destacked Ship 24, and CEO Elon Musk noted that the company was “proceeding very carefully” to avoid an explosion that could set “Starship progress back by ~6 months.”

But if there was a major issue on October 13th, SpaceX didn’t show it, and Ship 24 was reinstalled atop Booster 7 on October 20th without any obvious maintenance or repairs. SpaceX then kicked off an unusual series of tests on October 24th, during which it only filled the liquid oxygen (LOx) or liquid methane (LCH4) tanks of Super Heavy B7, Ship 24, or both vehicles at once. A rare NASA briefing on October 31st later called them “single-species prop[ellant]” tests – a kind of extra-cautious testing that had never been seen before at Starbase. A few days prior, a member of NASA’s Aerospace Safety Advisory Panel (ASAP) noted that an accidental explosion that damaged Booster 7 in July had caused SpaceX to “increase [the rigor of its] systems engineering and risk management,” explaining the sudden influx of unusually conservative testing.

By the time Ship 24 was destacked from Booster 7 on November 8th, SpaceX had completed seven single-species tests, four of which involved loading LOx or LCH4 into both stages and three of which only tested Super Heavy. Booster 7 and Ship 24’s tanks were fully filled and LCH4 and LOx were never simultaneously loaded on either stage.

NASA’s October 31st briefing reported that SpaceX had plans to destack Ship 24 before conducting additional static fire testing with Booster 7. While B7 completed 1, 3, and 7-engine static fires in August and September, those tests were nowhere close to the full 33-engine static fire required to properly qualify the most powerful rocket in history. According to NASASpaceflight.com managing editor Chris Bergin, SpaceX’s next goal is to fire up approximately half of Super Heavy B7’s Raptors.

Strangely, although Ship 24 was believed to have completed all of the standalone testing needed to clear it for flight, SpaceX installed the vehicle on a stand used for Starship static fire testing on November 9th, implying that more standalone testing may be required. For now, that shouldn’t pose a problem as long as SpaceX wraps up any additional Starship testing around the same time as Booster 7’s next static fire campaign wraps up, but it could delay full-stack launch readiness if it takes any longer.

Finally, after 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.

Assuming that Ship 25’s first several proof tests were successful, which they appear to have been, SpaceX returned the prototype to its Starbase factory to install six Raptor engines and a series of shields and firewalls that will protect those engines from each other. Once fully outfitted, Ship 25 will return to the launch site for static fire testing and take Ship 24’s place on Suborbital Pad B. Ship 24 took approximately two months to go from its last cryoproof to its first static fire. But its testing got off to a relatively rocky start, so Ship 25 could be ready sooner.

SpaceX could begin the next phases of Booster 7 and Ship 24 testing as early as November 10th or November 13th.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion

Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.

The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.

But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.

Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.

However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.

Wireless for Operation, Wired for Downtime

It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.

The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.

In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.

Induction Charging Challenges

Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.

While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.

Production Timing and Potential Challenges

With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.

It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.

In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years. 

The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.

Dry cathode 4680 cells

In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.

The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”

Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.

4680 packs for Model Y

Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla: 

“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”

The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line

This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.

Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.  

Optimus 4 production

In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas. 

This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4. 

“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.

How big Optimus could become

During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world. 

“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP. 

“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
