SpaceX’s workhorse Falcon 9 rocket is ready for the company’s 12th launch this year, set to send a reused Cargo Dragon spacecraft on its way to the International Space Station (ISS) and conclude with a surprise drone ship landing attempt.

SpaceX is about eight hours out from launching CRS-19, set to become Cargo Dragon’s 20th orbital mission and 19th space station rendezvous and resupply. It will also be the second time a single Cargo Dragon capsule flies its third orbital mission and the eight Dragon reuse overall, continuing proof that SpaceX is by far the leading global expert in launch vehicle and orbital spacecraft recovery and reuse.

Set to lift off no earlier than 12:51 pm ET (16:51 UTC), December 4th, CRS-19 will see flight-proven Cargo Dragon capsule C106 launch atop a new expendable trunk and upper stage, as well as a new Falcon 9 booster – an increasingly unusual sight. After a Falcon Heavy Block 5 launch completed earlier this year, SpaceX passed a threshold where it had recovered more boosters after launch than it had expended, equating to 40+ successful landings. Since Falcon 9 Block 5 – a reusability and reliability-focused upgrade – debuted in May 2018, sooty (i.e. flight-proven) boosters have become an increasingly common sight.

Between Falcon Heavy’s two 2019 launches, four new boosters marked their flight debut, while Falcon 9 missions have only debuted two new boosters – soon to be three after CRS-19. In other words, as of today, 7 of Falcon 9’s 9 2019 launches have involved flight-proven boosters – more than 75%. In fact, Block 5 is proving so robust that SpaceX has actually intentionally slowed down booster production at its Hawthorne, CA factory, hoping to instead treat its currently flightworthy rockets as a true fleet, cycling through them to launch dozens of missions.

Cargo Dragon with a (rare) side of drone ship

Beyond the rarity of a new booster’s launch debut and Cargo Dragon’s increasingly impressive history of reusability, CRS-19 – as discussed at length in earlier articles – will also see Falcon 9 booster B1058 attempt to land aboard drone ship Of Course I Still Love You (OCISLY) some 350 km (200 mi) downrange. Aside from CRS-17’s Crew Dragon explosion-related drone ship landing in May 2019, all CRS mission booster recoveries since April 2016 have landed (or at least attempted to land) at SpaceX’s Cape Canaveral-based LZ-1 or LZ-2 landing pads.

Close to shore by average drone ship landing standards but a cross-country jaunt compared to CRS-17’s unusual May 2019 booster landing aboard OCISLY, SpaceX explained the odd booster recovery plans in a routine prelaunch press conference yesterday afternoon.

“[After Dragon is deployed and CRS-19’s launch concludes], SpaceX is going to perform an…ambitious coast test, requiring larger propellant margins that must be withdrawn from Falcon 9’s own landing propellant budget.”

In short, SpaceX needs to leave more propellant for the upper stage, thus limiting B1058’s ability to boost all the way back to the Florida coast. Instead, it will only partially slow its Eastbound velocity, still leaving enough margin for drone ship OCISLY to station relatively close to the Florida coast compared to more common (and more demanding) booster recovery profiles.

All told, SpaceX says Falcon 9’s upper stage will attempt to perform a six-hour coast (“thermal test”) after CRS-19, concluding with a final Merlin Vacuum engine reignition and deorbit burn, similar to a test performed after CRS-18’s recent July 2019 launch. These tests are meant to satisfy what SpaceX described as the requirements of “other customers”, of which the USAF is by far the best known for its long-duration coast demands. For an upper stage powered by cryogenic liquid fuel, remaining fully functional for hours in orbit is one of the single greatest technical challenges that face modern rocketry.

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.
