SpaceX Starship factory churning out new rocket parts with Elon Musk's help
SpaceX’s South Texas team of Starship engineers and technicians – including CEO Elon Musk himself – are working around the clock to manufacture hardware that will likely become the company’s next Starship prototype in the near future.
Over the last few days, SpaceX has made quick progress churning out shiny steel rings and wrapping up propellant tank domes – the next round of full-scale Starship hardware. To better build the first flight and orbit-capable prototypes, not to mention hundreds or even thousands of Starship spacecraft and Super Heavy boosters in the years to come, SpaceX teams and contractors have spent the last two months aggressively expanding the company’s Boca Chica, Texas facilities. In fact, the very same company that built Tesla’s newest tent-based Model 3 assembly line – Sprung Instant Structures – has erected part of a massive, new Starship factory.
Finally giving the company’s grizzled South Texas team a large, climate-controlled space to work from, CEO Elon Musk has also been spending more and more time at SpaceX’s upgraded Boca Chica facilities. Most recently, the executive gave Twitter followers the first official glimpse inside one of the new Starship production tents, revealing several giant spacecraft parts in various stages of completion. It’s currently unclear what the destiny of that new Starship hardware will be, but a few recent clues seem to point in one specific direction.
Yeah, we just finished two more propellant domes. SpaceX team & supporting suppliers are doing amazing work ramping Starship production.— Elon Musk (@elonmusk) January 22, 2020
On January 10th, SpaceX intentionally – and largely successfully – ‘popped’ a Starship propellant tank to determine the quality of partially-upgraded manufacturing and assembly techniques. Built in just two weeks, Musk revealed shortly after the test that the baby Starship tank – filled with water – had made it to 7.1 bar (103 psi) before bursting.
While fairly meaningless on its own, it apparently means that the test tank survived well past the pressures Starships will need for orbital flight, although it only managed a safety margin of ~18%. To be fully flightworthy, Musk says that SpaceX wants Starship tanks to survive pressures of at least 8.5 bar (125 psi) – a margin of ~40% – before it considers the giant spacecraft safe enough for humans.
Given that the 7.1 bar the test tank reached is more than enough to support “orbital flight”, albeit with a less-than-optimal safety margin, it would be reasonable to assume that SpaceX would choose to immediately green-light the first flightworthy Starship spacecraft, deemed SN01 (serial number 01) by Musk. While that first prototype would thus be unable to launch humans and fulfill its ultimate goal as a Starship, it would give SpaceX experience building a second full-scale prototype (following Mk1) and give the company time to gradually upgrade its production facilities and manufacturing hardware.
Musk sketched out a number of possible improvements even before SpaceX tested its miniature Starship tank to destruction, indicating that “more precise parts” and an enclosed, wind-protected welding shop should be enough to raise Starship’s safety margin to ~40%. A step further down the road, Musk raised autogenous laser welding as a possibility for future production upgrades, although the advanced welding method would require a truly controlled environment and much more precise parts and manufacturing hardware.
In the last 24 hours, SpaceX has filed for a number of road closures for the highway adjacent to its Boca Chica Starship facilities, a sign that some form of rocket hardware transport and testing is imminent. As such, it now seems much more likely that SpaceX has decided to spend at least a few more weeks building and testing a second (and possibly a third) Starship tank prototype before kicking off the production of the next full-scale rocket.
Intriguingly, SpaceX has also received several large shipments of liquid nitrogen (LN2), a neutral cryogenic fluid often used to simulate cryogenic propellants without risking a massive explosion or fire. That LN2 wont last forever in SpaceX’s storage tanks, confirming that some form of cryogenic testing is imminent. The most likely explanation is that SpaceX is in the late stages of manufacturing a second tank prototype, soon to be shipped about a mile down the road to the company’s nearby test and launch facilities.
If SpaceX is planning to perform a burst test with liquid nitrogen, it will likely be quite the spectacle – much closer to Starship Mk1’s spectacular failure than the milder demise of the first miniature Starship tank. SpaceX has roadblocks scheduled every day for the rest of the week, so stay tuned to find out when exactly Starship’s next big test is expected.

Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:
Robotaxi rides without any safety monitors are now publicly available in Austin.
Starting with a few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors, and the ratio will increase over time. https://t.co/ShMpZjefwB

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
