SpaceX Falcon 9 rocket launches heaviest payload yet
SpaceX has launched its heaviest payload yet for the third time in ten months, demonstrating that it’s still finding ways to improve the performance of its mature Falcon rockets.
At 9:30 am EST, January 25th, SpaceX completed a static fire of the two-stage Falcon 9 rocket assigned to launch its next Starlink mission. Half an hour later, SpaceX confirmed that the rocket performed well and is scheduled to launch no earlier than 4:32 am EST (09:32 UTC) on Thursday, January 26th. SpaceX didn’t state the mission’s purpose, but shorthand (“sl5-2”) used in an official website URL implied that it would be the second launch for its Starlink Gen2 satellite constellation.
Flying for the ninth time, Falcon 9 booster B1067 lifted off on schedule and sent an expendable Falcon upper stage and Starlink 5-2’s 56-satellite payload on their way to space. B1067 safely touched down on a SpaceX drone ship soon after, setting it up to reach double digits later this year. The bus-sized stack of satellites was deployed in orbit soon after, completing SpaceX’s 176th consecutively successful launch since January 2017.

Eleven Teslas to orbit
56 is not an unprecedented number of satellites for a SpaceX launch or a Starlink launch. SpaceX has launched a record 143 rideshare payloads at once, and the company routinely launched 60 Starlink satellites at a time throughout 2019, 2020, and half of 2021. But those Starlink satellites were the first versions (V0.9-V1.0) of the spacecraft and weighed either 227 or 260 kilograms (500/570 lbs) apiece.
In the second half of 2021, SpaceX began launching new Starlink V1.5 satellites. Outfitted with laser links (optical terminals) and other miscellaneous upgrades, the new satellites weigh either 303, 307, or 309 kilograms (668, 676, or 681 lb) each. The heavier design forced SpaceX to slightly reduce the number of satellites each launch could carry. After some optimization, SpaceX regularly launches up to 54 Starlink V1.5 satellites per rocket, down from 60 V1.0 satellites.
The number of satellites may be smaller, but the mass of the payload launched has never been higher. SpaceX last broke Falcon 9’s payload mass record in August 2022, when it launched 54 Starlink V1.5 satellites for the first time. The payload reportedly weighed 16.7 tons (~36,800 lb), breaking the previous record of 16.25 tons by about 3%. The heaviest 60-satellite Starlink V1.0 payload weighed ~15.6 tons (~34,400 lb).

Now, Falcon 9 has launched 56 Starlink V1.5 satellites at once. SpaceX says the payload weighed 17.4 tons (~38,400 lb), crushing the company’s previous record of 16.7 tons. 17.4 tons is just shy of the weight of 11 Tesla Model 3s.
Starlink 5-2 targeted the same orbit as Starlink 5-1, which carried 54 satellites, indicating that SpaceX has likely made another iterative improvement to Falcon 9 performance. As SpaceX has gained confidence in and experience with Falcon 9, it’s been able to tweak the timing of certain launch events, raise performance limits, and reduce margins throughout the rocket. Starlink 5-2’s record payload means that SpaceX’s tweaks have collectively boosted Falcon 9’s performance by 11.5% (15.6 to 17.4 tons) in just a few years.
Gen1, V1.0, V1.5, Gen2, V2.0
Starlink 5-2 continues a trend of confusion begun by the company’s first Starlink Gen2 launch, which it deemed Starlink 5-1. The naming scheme implied that the satellites were a continuation of the company’s first constellation, Starlink Gen1, but SpaceX confirmed that they were the first Starlink Gen2 satellites. That SpaceX is launching 54 (and now 56) satellites also confirms that they are likely the same V1.5 satellites the company has been launching for 18 months.
SpaceX CEO Elon Musk has outright stated that the company could go bankrupt if it couldn’t begin launching much larger Starlink V2.0 satellites on its Starship rocket in the near future. Instead, SpaceX is doing the exact opposite and is populating its Starlink Gen2 constellation with Gen1-sized satellites. It’s unclear when SpaceX will begin launching the larger Starlink V2.0 satellites that were meant to be the mainstay of the Gen2 constellation.

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.
