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.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
