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.

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.

The Boring Company’s latest Tesla tunnel truck mod “fits like a glove”
The Boring Company has modified a Tesla powered tunnel truck to carry freight containers underground.
The Boring Company has found a second job for the Tesla hardware it already runs underground. In a post on X, Elon Musk’s tunneling company showed its latest Prufrock Liner Truck modified to carry a standard 20 foot shipping container. “Using TBC tunnels to transport freight,” the company wrote. “The latest Prufrock Liner Truck (using Tesla Model 3 batteries and drive units) has been modified to carry a standard 20′ shipping container. Fits like a glove!”
The photo shows a red container sitting on a long, low white chassis parked outside, with drive hardware visible at one end. The Boring Company did not say where or when freight hauling would start, which customers it has in mind, or how many trucks it is converting.

Until now, the liner trucks have hauled concrete. Teslarati reported in August on Liner Truck 3, which uses Model 3 battery packs and drive units to move more than 22,000 pounds of precast tunnel segments to the boring machine. It has 28 miles of range, tops out at 12 mph, and is piloted remotely from the company’s operations center in Texas. The freight version appears to be the same platform with a different bed, and The Boring Company has not said whether it will also be remotely piloted.
Freight has been on the company’s menu for years. When TBC updated its product lineup in 2021, its freight tunnel was described as sized to fit a standard shipping container, “barely.” The company later used the idea at Tesla’s own factory, where Prufrock 3 dug a tunnel to Giga Texas that now moves finished Cybertrucks away from the production line.
The Boring Company closed a $3 billion Series D in September at a $23 billion valuation, and Teslarati has covered how that money is tied to a UAE tunneling push and a faster Nashville build. In Nashville, Prufrock MB1 and MB2 are mining at the same time, and a third machine is expected to launch in late October. Each machine needs a steady supply of liner trucks, so any design that works for segments and containers alike gives the company more use out of the same Tesla parts.
The Vegas Loop remains the only Boring Company system open to the public, and it moves passengers in Tesla vehicles. A freight service would be a separate product, and the post gave no indication that one is close to launch. For now, it is a truck, a container and a short caption saying they fit together.
Elon Musk said he is planning to give “every one of his SpaceX shares to every kid in America” in 2027, stating that “this will be the first of many.”
SpaceX went public earlier this year, and its stock price has been relatively stable since leveling off shortly after its IPO. Based on its current price, it’s a gift of just over $10 billion to children across the United States.
It appears to be closely related to President Donald Trump’s bank accounts for children, which were set up earlier this year as Trump Accounts.
Just hours earlier, Anthropic had announced the establishment of its Anthropic Public Benefit Fund, “a new wholly-owned entity dedicated entirely to public benefit.” Musk responded by stating he recommended “giving the shares directly to the public,” and that he would be doing it that way.
Just a little bit later, Musk said children across the U.S. would be getting a share from him:
Next year, I will give one of my SpaceX shares to every kid in America.
This will be the first of many.

There are roughly 70 million children, meaning someone under the age of 18, in the United States, according to the Federal Interagency Forum on Child and Family Statistics. Musk’s ownership of SpaceX stock shows he has around 849 million Class A shares of SpaceX stock, according to filings with the SEC.
Elon Musk revealed in a post on X that “Permits were impossible to get,” explaining the fate of The Boring Company’s most ambitious East Coast proposal.
The comment responded to a query about what became of his July 20, 2017 announcement that he had “just received verbal govt approval” for an underground Hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, D.C., capable of carrying passengers from the Big Apple to the Nation’s Capital in just 29 minutes.

The 2017 post, which envisioned city-center stations and multiple elevators in each city, sparked immediate scrutiny. Local and state officials in New York, Philadelphia, Baltimore, and D.C. said they had no knowledge of any approval. A White House spokesperson confirmed only “promising conversations” about the transformative infrastructure.
Musk clarified shortly after that there was “still a lot of work” to do for formal approvals.

Limited progress followed, as Maryland Governor Larry Hogan’s administration issued a conditional utility permit and supported work near Fort Meade. In 2018, Washington, D.C., granted a preliminary permit for site preparation and excavation on a vacant lot at 53 New York Ave. NE in the NoMa neighborhood, which The Boring Company said could become a station.
A draft environmental assessment for a D.C.-Baltimore segment was released in 2019. Yet, by April 2021, the company had removed the project from its website, and the Federal Highway Administration reported receiving no indication of further interest. Communication with Maryland officials had ceased.
The full corridor would have required coordination among the District of Columbia, Maryland, Pennsylvania, New York, the Federal Highway Administration, the Army Corps of Engineers, the National Park Service, and other agencies.
Environmental reviews under the National Environmental Policy Act, utility clearances, and approvals for novel infrastructure added to the overall complexity of the project and its approval.
Speculation on the permitting barriers centers around a few factors, but a multi-state, multi-level route involving unproven high-speed vacuum-tube technology inherently triggers exhaustive safety, environmental, and engineering reviews that can stretch for years, even for conventional projects.
There are also other elements, of course, like officials who may face political exposure if a privately funded, untested system encountered anything such as cost overruns, delays, or safety issues. On the outset of this project, there were limited things such as engineering plans or demonstrated technology maturity, which also added to the potential skepticism.
The East Coast vision for Boring Co., once framed as a privately funded revolution that could reshape Northeast travel, quietly ended without construction of the promised network. Musk’s recent statement frames the outcome as a regulatory impasse, unfortunate but not unexpected.
