SpaceX’s Starship factory is churning out steel rockets faster than ever
SpaceX’s South Texas Starship factory is churning out steel rocket hardware faster than ever before according to photos of yet another prototype already in the works.
At the same time as SpaceX works around the clock to test SN4 and prepare the ship for what will be the first flight of a full-scale Starship prototype, the company is building not one; not two; but three additional prototypes. A confirmation that a third Starship was being simultaneously manufactured in South Texas came on May 25th when local Boca Chica resident and observer Mary (bocachicagal) captured a photo of a pair of stacked steel rings rather conspicuously labeled “SN7”.
While it’s possible that “SN7” is just a coincidence, it’s far more likely that it refers to Starship serial number 7 (SN7), set to be the seventh full-scale prototype built by SpaceX. The apparent start of SN7’s steel ring assembly process some two weeks ago also suggests that no less than several other rings are likely being mated in one or more of SpaceX’s three main manufacturing tents or a much taller windbreak structure. In fact, SpaceX is building Starship prototypes so quickly that the company is actively assembling a second launch mount, suggesting that two Starships could soon be tested more or less simultaneously without stepping on each other’s steel toes.


The most impressive aspect of SN7’s appearance, however, is the fact that SpaceX is already in the late stages of stacking Starship SN5 and begun preparing to stack Starship SN6 directly beside it just a few days ago. Based on labels attached to the side of a new steel nosecone section rolled out of SpaceX’s tent factory a few days ago, Starship SN5 will likely become the first full-scale Starship to reach its full height in a permanent, functional fashion. Back in October 2019, SpaceX did technically stack Starship Mk1 to its full height for a few weeks, but the ship’s nose section was never permanently attached and really only served as a pathfinder and full-scale mockup.

Starship Mk1 ultimately failed prematurely during its first major cryogenic pressure test in November 2019, bursting well before it reached the tank pressures needed for low-velocity hop tests (let alone orbital flight). In the sixth months since, SpaceX refocused its resources and spent much of the time dramatically upgrading its South Texas Starship production facilities and methods. In a rapid-fire series of tests of custom-built Starship tanks, SpaceX quickly proved that those improved methods could produce steel tanks more than capable of surviving pressures of ~8.5 bar (~125 psi) and beyond.
More recently, Starship SN4 – a full-scale prototype with two propellant tanks and three tank domes – passed a ~7.5 bar (~110 psi) cryogenic pressure test with flying colors, just shy of fully validating the smaller tank tests that made it possible. According to CEO Elon Musk, ~8.5 bar is enough to perform orbital launches with the ~40% safety margin preferred for human spaceflight, while 7.5 bar meets the minimum needed for Starship to perform uncrewed orbital launches with a ~25% safety margin.

In other words, SpaceX isn’t simply churning out low-fidelity prototypes – the ships that are being mass-produced are of a high enough quality to be qualified for orbital-class launches. Of course, the physical structure of Starship is just one of many technologies that need to work in harmony for successful orbital flights, many of which need to pass their own challenging tests to be declared ready for launch, but it’s still undeniably impressive that SpaceX is already building complete Starship fuselages in a matter of weeks.
In fact, given that Starship SN4 could perform the first hop test and that SN5 could be assigned to the first high-altitude (3-20+ km) flight tests, there is definitely a chance, however minimal, that Starship SN6 or SN7 could eventually be upgraded for the system’s inaugural orbital launch attempt. Regardless, it’s safe to say that the next several weeks are going to be jam-packed with numerous Starship production and test milestones.

Elon Musk’s next Uranium in Uranus merch is Boring Company’s weirdest tease yet
Elon Musk teased a glowing new Boring Company merch idea, complete with a Geiger counter.
Elon Musk teased the next piece of Boring Company merchandise on X Saturday, and it is exactly as unserious as fans of the company’s product history have come to expect. “The next @boringcompany merch will put Uranium in Uranus,” Musk wrote in a thread posted early Saturday morning. He followed up by explaining that the item would glow in the dark, “because otherwise how could you find it,” and that a Geiger counter would be sold separately as “an optional strap-on.”
Musk closed the thread with a line that doubles as a mission statement for the tunneling company’s merchandise arm: “It’s not easy coming up with something that is both outrageously unsellable and yet extremely popular.”
The Boring Company has built a small but consistent side business out of novelty items that start as jokes and end up selling out. The company’s Not-a-Flamethrower raised roughly $10 million in a few days back in 2018, moving all 20,000 units it produced. Its Burnt Hair perfume, priced around $100 a bottle, sold out fast enough that scalpers were flipping units on eBay for ten times the retail price. Boring Bricks, made from tunneling spoil, followed the same playbook of teasing a product on X months before it became real.
Musk has not said what the actual item will be, only that it involves uranium and glows in the dark. Given the pattern, that vagueness is probably intentional. Past merch announcements have started as one-line jokes and taken weeks or months to turn into an actual product listing on the company’s site, and there is no guarantee this one follows through at all.
The timing lines up with a period of real momentum for the Boring Company outside of the joke merchandise. The company said last week it plans to double the number of operational stations on its Vegas Loop by the end of the year, a target tied to a hiring push for drivers and operations managers. Prufrock-5, one of the company’s tunnel boring machines, also just wrapped a test tunnel in Bastrop, Texas, and is expected to relaunch on its next assignment in November.
Whether the uranium joke turns into an actual product remains to be seen. Musk’s post did not include a price, a shipping date, or even a name for the item, which has historically meant a Boring Company website page goes up quietly, password protected, sometime before an announcement.

NASA taps SpaceX for more astronaut missions as Boeing Starliner remains grounded
NASA just gave SpaceX a $946 million contract for three more astronaut missions through 2030.
NASA has awarded SpaceX a $946 million contract modification covering three more astronaut missions to the International Space Station, according to an announcement the agency published Friday. The award adds Crew-15, Crew-16, and Crew-17 to SpaceX’s existing Commercial Crew Transportation Capability contract, bringing the agreement’s total value to $5.92 billion across 17 flights.
SpaceX confirmed the award on X, writing that it was excited for Falcon 9 and Dragon to launch NASA’s Crew-15, 16, and 17 missions to the Space Station from Florida. The new missions cover ground, launch, in orbit, and return operations, along with cargo transport and a lifeboat capability while docked at the station, and the period of performance runs through 2030.

The award follows a notice of intent NASA issued in May, when the agency first signaled it would purchase up to six additional post certification missions from SpaceX. Teslarati covered that filing at the time, noting NASA cited technical issues and schedule delays encountered by Boeing as a driving factor. Friday’s contract modification locks in three of those six missions, with the remaining three left open for NASA to award later, potentially to Boeing if Starliner clears certification.
Boeing’s CST-100 Starliner has still not flown an operational crew rotation mission for NASA. The spacecraft’s most recent crewed test flight in 2024 ended without the astronauts returning aboard Starliner, and the company has spent the time since working through thruster problems. SpaceX President Gwynne Shotwell said this week that SpaceX is not retiring Crew Dragon today, for sure, while stopping short of committing to fly it past 2030.
Crew-12 is currently docked at the space station, and NASA has said Crew-13 is targeting a launch in the coming weeks. The newly awarded Crew-15 through Crew-17 missions extend SpaceX’s role as NASA’s primary way of getting astronauts to and from orbit well into the back half of the decade, regardless of what happens with Starliner or Starship in the meantime.

New drone video shows Tesla’s Optimus Factory reaching a turning point
New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.
Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.
The Giga Texas Optimus Factory latest update … construction keeps moving fast!

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.
Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.
Tesla Giga Texas to feature massive Optimus V4 production line
The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.
Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.
