SpaceX repairing heat shield, reinstalling Raptors on first orbital-class Starship

SpaceX has begun reinstalling three of the six Raptor engines that will power the first orbital-class Starship and repairing the heat shield that will hopefully protect it on its first trip to space.

Known as Starship 20 or S20, the 50m (~165 ft) tall steel rocket prototype has been stationed at one of SpaceX’s two suborbital testing pads since August 13th. No testing has been done, though, and a small army of SpaceX technicians and engineers have instead spent the last three or so weeks effectively turning a collection of steel tanks, tubes, and parts into a functional rocket. While it’s unclear why SpaceX chose to do that outfitting work at an unsheltered launch pad, new activity suggests that it may be almost complete.

Exactly one month ago, SpaceX stacked Starship S20 on top of Super Heavy Booster 4 (B4) on August 6th, briefly creating the largest rocket in history and completing a fit test that was admittedly just as much a photo op. Ship 20 was rapidly destacked and returned to SpaceX’s Starbase factory, where all six of its Raptor engines were removed. About a week later, Ship 20 returned to the pad and has remained installed on Suborbital Pad B ever since.

At the time, the implication was that SpaceX had removed Ship 20’s engines to allow the prototype to complete cryogenic proof testing with hydraulic thrust simulators. However, despite having carefully modified Pad B over several weeks for that exact purpose, those modifications were rapidly removed before Ship 20’s second rollout. Precluding a proof test with thrust simulation, the next logical conclusion was that SpaceX would still perform a cryogenic proof test before reinstalling Ship 20’s Raptors and moving on to a static fire campaign.

Now, even that appears to have been p1recluded. Instead, as if Ship 20 were the second or third or fourth in a series of prototypes, SpaceX rolled three center Raptors to Pad B on September 5th and began installing the engines on Starship on the 6th. It’s hard to say anything with confidence given how chaotically Starship S20’s to-be-determined qualification testing has changed in the last several weeks but, with plenty of uncertainty, Raptor installation implies that the vehicle will perform its first ambient pressure and cryogenic proof tests with engines installed.

It remains to be seen if Ship 20’s three vacuum-optimized Raptor engines will also be installed over the next few days (seemingly the logical assumption) or if SpaceX will instead complete proof tests and center Raptor static fire testing before finally moving into new territory. SpaceX has never static fired more than three Raptors at once and certainly never tested multiple Raptor Vacuum (RVac) engines in close proximity – let alone all six simultaneously.

Photos taken on August 18th, 28th, and September 3rd by Philip Bottin and Starship Gazer show the slow, steady process if finishing (and fixing) Starship S20’s heat shield.

Meanwhile, much of the focus of the last few weeks appears to have been on finishing Ship 20 plumbing and avionics wire runs, though it’s hard to say exactly what has been done. What is extremely visible and easy to follow, though, is the process of finishing the first orbital-class Starship heat shield and repairing a few hundred tiles broken during its pathfinder installation. SpaceX has installed 500-1000+ tiles on flown Starship prototypes like SN15 but the company has never come close to the ~15,000 needed to cover the entire windward side of the world’s largest rocket upper stage.

SpaceX has undertaken that process for the first time over the last six or so weeks and unsurprisingly seen a number of successes and failures. At some point along the way, a significant fraction of the ceramic, dinner-plate-sized tiles SpaceX technicians installed chipped, broke, shattered, or ran into other fitment issues. Over the last month or so, a great deal of progress has been made fixing those problem tiles and SpaceX has also more or less completed tile installation on the angular ‘aerocovers’ that protect Starship’s flap mechanisms – requiring dozens of custom tiles with complex shapes and curves.

As of September 6th, Starship S20’s heat shield appears to be around 95% complete and the installation of Raptor engines implies that the rocket’s plumbing, avionics, and tankage are also nearly finished. In other words, after many weeks of work, SpaceX’s first orbital-class Starship prototype could be ready to kick off cryoproof and static fire testing just a week or so (and maybe less) from now. Stay tuned for updates!

SpaceX hid behind another name in the Arizona desert, and now it’s going big

SpaceX puts a $50 billion price on its Arizona supercompute campus ahead of December’s hearing.

SpaceX has put a price tag on the supercomputer campus it wants to build in the southern Arizona desert. In a statement Thursday, the company said it is pursuing a roughly $50 billion supercompute campus in Cochise County, about 80 miles east of Tucson. Together with a separate facility planned at Starbase, Texas, the two projects add up to more than $74 billion in planned investment.

The Arizona figure had not been disclosed before. SpaceX’s involvement only became public on November 4, when company representatives hosted a packed town hall at Cochise Elementary School for an application filed under the name Tombstone Resources LLC. A SpaceX representative told residents the filing used another name because putting SpaceX on it “draws attention” from outside the county, local station KVOA reported.

The application describes a 747-acre site near the Willcox Playa with up to nine buildings of about 493,000 square feet each. SpaceX plans to bring the campus online in four phases of roughly 1.5 GW, reaching 6 GW at full build, backed by a 24 GWh battery system and about $3.6 billion in grid upgrades. At that size, it would draw about 2.5 times more power than every data center in Maricopa County combined, according to an Arizona Republic analysis.

SpaceX says the project will create about 5,500 construction jobs and 1,000 permanent jobs, and that it could cut electricity bills for members of the local cooperatives by up to 20 percent. The campus would use dry cooling with no industrial groundwater use. Its application estimates ongoing water needs of 7 to 10 acre-feet a year, roughly what 20 to 30 homes consume.

Power is the bigger question. The site sits next to the Apache Generating Station, a coal and natural gas plant with about 1 GW of capacity that had been slated to retire by 2028. SpaceX told residents its investment could expand the station to more than 6 GW.

Local opposition is organized. A petition asking the county to deny the permit has gathered about 2,400 signatures, and the nearby playa is a landing spot for federally protected sandhill cranes, which SpaceX says its design accounts for. The Cochise County Planning and Zoning Commission will hold a public hearing on December 9 in Bisbee, with written comments due November 27. If approved, construction could start in March 2027.

The Texas project faces a vote the same day. The Starbase City Commission will consider a property tax abatement for SpaceX’s $24 billion gas plant and supercompute facility at its own December 9 hearing, as Teslarati reported. SpaceX said Thursday the Starbase site has already generated more than 3,000 construction jobs, and it committed $220 million to Brownsville’s water and wastewater systems, $40 million of which has been paid.

Both campuses would expand a footprint still centered on the Memphis area, where SpaceX’s Colossus data centers run largely on gas turbines and the company won a permit for a power plant in Southaven, Mississippi earlier this year. SpaceX ended the third quarter with 1.7 GW of nameplate compute. The Arizona campus alone, at full build, would be more than three times that size.

Nvidia’s board meets on Jensen Huang, and Elon Musk already has an answer

Elon Musk says it would be an honor to hire Jensen Huang amid Nvidia turmoil.

Published

Elon Musk says he would welcome Jensen Huang at one of his companies if Nvidia’s board decides to push out its longtime chief executive.

On Wednesday evening, the financial account ZeroHedge posted “Elon please hire Jensen” on X. Musk replied roughly two hours later: “That would be an honor.” Neither Huang nor Nvidia had responded publicly as of Wednesday night.

Musk’s reply came as Nvidia’s board met to decide Huang’s future. The Wall Street Journal reported that directors were preparing to oust him following reports of two extramarital relationships. One involves Alice Huang, a Singapore-based businesswoman whom U.S. intelligence officials reportedly believe was working for China’s Ministry of State Security. The New York Times separately reported a relationship with Kimberly Powell, Nvidia’s vice president of health care. Huang acknowledged being unfaithful in a memo to employees on Sunday but gave no details.


Under Nvidia’s bylaws, a majority of its 11 directors can remove the CEO with or without cause. Bloomberg reported that the board has been working with an outside firm on possible replacements and may name an interim chief, with CFO Colette Kress seen as the likely pick. Nvidia shares fell more than 8 percent in extended trading, according to CNBC, and the company is scheduled to report quarterly earnings on November 17.

Musk has more riding on Nvidia’s leadership than most tech executives. In August, he told investors on SpaceX’s first earnings call as a public company that it would build its AI infrastructure exclusively on Nvidia hardware, calling Vera Rubin “the best architecture.” SpaceX is also working with Nvidia on the compute payload for Starmind, its planned orbital AI constellation. In October, SpaceX said it had a binding commitment for a roughly $40 billion lease of Vera Rubin GPUs and related equipment, with the leases expected to begin in the first half of 2027.

The scale of that dependence is already enormous. On its Q3 call, SpaceX said it was bringing roughly 200,000 to 220,000 Nvidia GB300 GPUs online each month and expects 2.5 to 3 GW of nameplate compute by the end of the year. That buildout is now reaching new sites like the proposed $24 billion power plant and supercomputer campus at Starbase.

The relationship between the two executives also goes back nearly a decade. Huang has often told the story of personally delivering Nvidia’s first DGX-1 AI supercomputer to Musk in 2016, when no other customer wanted one. “Nobody wanted to be part of it, except for Elon,” Huang said on the Joe Rogan Experience last December.

Musk did not say what role Huang might fill, and his reply stops short of a formal offer. Huang co-founded Nvidia in 1993 and still owns about 3.6 percent of its stock, so any move to a Musk company would depend on whether, and how, he leaves the chipmaker he has run for more than three decades.

Starlink Mini 2 arrives with one feature for true off-grid connectivity

Published

Credit: SpaceX

SpaceX officially launched the Starlink Mini 2 on November 10, delivering the first portable Starlink terminal designed around independent power.

Invitation-only preorders for select U.S. customers are priced at $999 plus tax, a figure that includes a full year of Roam Unlimited service valued at roughly $2,100. A refundable $100 deposit reserves the kit, with the balance due at shipment, expected to begin in mid-December. Broader availability is listed as coming soon.

The headline feature is the quick-swap 71 Wh battery. Clipped to the rear of the dish without tools, it delivers up to 4.5 hours of connectivity on a single charge.

The 490-gram pack includes its own USB-C port and LED indicators, so users can charge a spare separately and swap it in seconds while staying online. Starlink notes that the terminal can continue operating while the battery charges or run directly from a 60 W USB-C source. The retail box includes one battery, a 60 W USB-C charger, and a 3-meter cable.

Beyond power, the Mini 2 is thinner at 23.1 mm (versus 38.5 mm on the original Mini) while measuring 263 × 314 mm. With the battery and kickstand attached it weighs 1.6 kg.

Built-in Wi-Fi 6 expands coverage to up to 1,800 square feet, an IP67 rating protects against dust and water, and a standard 1/4-20 tripod thread plus physical power button round out the design. Field of view remains 110 degrees, and the unit retains support for mobile use.

For travelers, campers, and remote workers, the swappable battery removes the longstanding requirement for an external power bank or vehicle outlet that defined the first Mini. Spare packs sold separately further extend runtime, turning the compact terminal into a more self-contained solution.

While the bundled $999 invitation price sits well above the original Mini’s current $149 starting point, the included year of service and genuine untethered operation mark a clear step forward in portable satellite internet.
