Elon Musk says SpaceX could fire up first orbital-class Super Heavy booster next week
Update: In response to this article, SpaceX CEO Elon Musk says that the plan is to not only ‘cryoproof’ the first flightworthy Super Heavy – but to static fire the booster and shake down Starship’s brand new orbital launch complex as early as “next week.”
A lot of work would need to be finished – and all of it smoothly – for an orbital launch pad cryoproof and static fire to be possible just a week or less from now but Musk’s response nevertheless provides invaluable context for SpaceX’s near-term plans and confirms that Super Heavy Booster 4 is ready for integrated testing as-is. Further, Musk’s tweet implies – as speculated – that Starbase’s orbital launch complex tank farm is much closer to test-readiness than it might otherwise appear.
For the second time in five weeks, SpaceX has installed a Super Heavy booster – fitted with 29 Raptor engines – on Starship’s nascent ‘orbital launch mount.’
Both Super Heavy Booster 4 (B4) and the launch mount have undergone substantial changes since they last parted ways four weeks ago. SpaceX teams have been laser-focused on installing the vast array of plumbing, wiring, and components required to turn the hulking steel structures into functional launch facilities and the largest flightworthy rocket and both certainly look the part.

Unlike Starship, which has an expansive skirt section perfect for stowing away sensitive plumbing and avionics, Super Heavy has an unusually short interstage and no real skirt, meaning that all the extra hardware SpaceX has installed over the last month or so is impossible to hide. Indeed, when Booster 4 rolled out of Starbase’s high bay for the second time on September 8th, the rocket was blanketed by dozens of new valves, thousands of feet of wiring and plumbing, pressure vessels, multiple hydraulic racks, a ‘quick disconnect’ (QD) umbilical panel for interfacing with the launch pad, places for “flight termination system” (FTS) explosive charges to be installed, and much, much more.

Additionally, Super Heavy B4’s second batch of 29 Raptors – installed in late August – also appear to all have outward-facing umbilical panels that will all the booster to receive some level of assistance from ground systems while igniting those engines. It’s unclear what exactly they’ll do but it’s likely that those engine umbilical will connect to high-pressure gas systems on the ground, presumably minimizing the already absurd amount of COPVs and secondary plumbing present on Super Heavy.
However, Super Heavy will still need to be able to reignite anywhere from 1 to 13 of its 29-32 Raptor engines in flight for boostback and landing burns, potentially explaining the eight large pressure vessels and 100+ small, high-pressure gas lines installed on B4’s aft end. Super Heavy also needs to be able to chill, feed, and purge all 29-32 of its Raptor engines, guaranteeing that Starship’s booster plumbing situation was going to be immensely complex no matter the approach SpaceX took.
In addition to Super Heavy B4’s newfound complexity, SpaceX also spent the last four or so weeks outfitting Starbase’s orbital launch mount’ with all the plumbing, power, avionics, and mechanical systems it will need to function as “Stage Zero” of orbital-class, two-stage Starship rockets. SpaceX has installed most of the secondary quick disconnect structures that will connect to and feed each of Super Heavy’s 20 outer Raptor engines. The main Super Heavy quick disconnect device was also installed and a team has been gradually outfitting and connecting the structure to the plumbing, avionics, and power it will provide boosters.

A significant amount of work still remains to connect the orbital launch mount to SpaceX’s incomplete and custom-built orbital tank farm, which will store, supercool, and feed the pad, Super Heavy, and Starship with several thousand metric tons of liquid and gaseous oxygen and methane. It’s difficult to say how close Starbase’s tank farm is to being able to support Starship or Super Heavy testing, which makes it equally unclear what SpaceX’s near-term plans are for Booster 4. It’s possible that the rocket has been reinstalled on the orbital launch mount as a second fit check, perhaps focused on those 20 outer Raptor quick-disconnect mechanisms.
It’s also possible that the tank farm and launch mount plumbing are much closer to completion than expected, meaning that Super Heavy B4 could remain at the orbital pad until it’s completed several crucial cryogenic proof and static fire tests. Of course, short of confirmation from Musk himself, we’ll just have to wait and see.

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.

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.
