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 Cybertruck Lead Engineer Wes Morrill revealed the company has made several changes to the all-electric pickup, which he calls a “living thing, constantly evolving and improving.”
Cybertruck is manufactured at Tesla’s Gigafactory Texas just outside of Austin, and over the past few years, Tesla has continued to make small changes to the pickup to improve everything from cost, reliability, serviceablility, and manufacturability.
“The finish line isn’t getting to production. A product is a living thing, constantly evolving and improving,” Morrill added.

Some of those changes are yet to be revealed, but perhaps the most notable one was the change Tesla made to the aero shield that sits underneath the truck. In the past, it was aluminum, but now the Cybertruck is using a self-reinforcing polypropylene.
Morrill said that the polypropylene is “stretched into fibers and then laminated into the form,” and is much more durable, much lighter, and significantly cheaper than aluminum when it is manufactured this way.
It also enabled some improvements in the geometry of the Cybertruck, improving the manufacturing around the bolts and edges, in addition to minor form changes. These all benefitted the Cybertruck in more ways than one: specifically with durability and improved drag.
I was surprised by how interested people were to find out we made a relatively benign change to the Cybertruck aero shield, a part of the car most people never even see. So I’ll share some more details.

Typically, Teslas are not necessarily identified by model year because these changes are fluid and occur when the company sees fit to implement them. It is not like other automotive companies, which usually make sweeping manufacturing changes when building a new model year.
Instead, Teslas are recognized by their “generation” or “era.” For example, those with a newer Model Y might refer to their car as a “Juniper.” This is the same with Model 3, as many refer to the new body style as the “Highland.”
Tesla’s manufacturing changes are proof of the company’s constant need to improve its products and move things forward with its vehicles. There is no need to drag one’s feet and wait until next year if the product can be made better right now, and that’s precisely what Tesla did with the Cybertruck.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.
Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
