On May 20th, SpaceX technicians successfully stacked a nosecone on top of the company’s Boca Chica orbital Starship prototype. Simultaneously, a separate team of technicians and engineers have been hard at work building a second similar-but-different Starship prototype near Cape Canaveral, Florida.

Officially confirmed last week by Elon Musk, the SpaceX CEO revealed that the company was not only building two orbital Starship prototypes simultaneously – not news in itself – but that those prototypes were being built as a sort of internal competition between different teams and ideas. The competition is not cutthroat – knowledge is shared between Texas and Florida – but the strategy is fairly similar. In lieu of actual commercial competitors, SpaceX is attempting to compete with itself to more rapidly and effectively develop a brand new launch vehicle – the stainless steel Starship/Super Heavy.

A Starship rises in the East

In just the last week, both SpaceX groups have made major progress. On the East Coast, the general public saw the first photo of SpaceX’s Florida Starship build precisely seven days ago. It appears that SpaceX has more or less taken over a Cocoa, Florida facility known to be the prior home of Coastal Steel, a repeat NASA contractor known for steelwork.

It’s unclear if SpaceX has fully acquired Coastal Steel or is simply partnering with the small company in the early stages of its Florida Starship buildup. Regardless, even from perspectives quite a bit more distant than those available in Texas, it’s clear that the metal workmanship is at least on par with Boca Chica, if not giving them a run for their money.

Admittedly, the playing field is not exactly level. SpaceX’s South Texas team has been working just a few thousand feet away from the unobstructed Gulf of Mexico in conditions that would make for an excellent traditional-aerospace horror show. Aside from a lone tent, all welding, assembly, integration, and testing has been done while fully exposed to the elements. SpaceX’s Florida team appears to have the luxury of an established warehouse – previously used for steelwork – to use as a covered and partially insulated work and staging area. The Florida team effectively had everything they needed (give or take) on hand from the moment work began, while Texas had to quite literally build all of its facilities from nothing.

Be it the facility luxuries or Cape Canaveral’s far larger pool of local aerospace talent, it’s clear that SpaceX’s Florida team will be a competitive force to be reckoned with despite Texas’ apparent head start. In the seven days since the first photos of the Florida Starship were published, SpaceX technicians have almost doubled the height of the largest welded section, raising it from ~5.5m to ~9m (18-30 ft).

Meanwhile, those working inside the staging warehouse continue to crank out 2x9m subsections, already making way for what appears to be the first tapered nose section of the Florida Starship. At this rate, Florida could very well catch up to SpaceX’s Texas Starship just a month or two from now. It’s worth noting that the Florida team does not appear to be involved in any Starhopper activities. SpaceX Boca Chica, on the other hand, has spent a major portion of the last several months building out Starhopper and preparing the odd prototype for untethered hop tests.

The (slightly) Old(er) Guard

Despite Starship Florida’s rapid progress, Starship Texas has not exactly been standing around. In the last week or so, SpaceX technicians and engineers have been simultaneously working on major new integration, assembly, and test campaigns with both Starhopper and the first orbital Starship prototype. A dedicated Starhopper article will come later this week as SpaceX’s South Texas team nears Raptor reinstallation and an untethered hop test campaign, scheduled to begin as early as the end of May.

On the orbital Starship side of things, Boca Chica took a major symbolic step towards aeroshell completion by capping off the upper half of the prototype with a stainless steel nose section. Altogether, the Starship assembly now stands about 25m (80 ft) tall from tip to tail, roughly 60% as tall as a Falcon 9 booster (first stage). With the installation of the craft’s nose, SpaceX has also implicitly confirmed that most – if not all – of the Starship prototype’s tankage still needs to be built, unless a great deal of hardware is hiding inside Boca Chica’s on-site tent.

What could either be the orbital Starship’s seven-Raptor engine section or the start of its liquid oxygen or methane tank is also being built a few hundred feet distant. That mystery segment was recently lifted onto a second concrete jig for easier access, while SpaceX has also been hard at work building a dedicated integration facility similar to the warehouse being used in Florida.

Altogether, SpaceX’s South Texas team appears to be 30-40% away from completing a Starship-sized steel aeroshell. A huge amount of work remains to be done on the inside of the theoretically orbit-capable vehicle, including propellant tanks, a thrust structure capable of supporting seven Raptor engines, landing legs/fins, and a jungle of plumbing and avionics installation. Still, the amount of progress already visible is undeniably impressive, made even more intriguing by the existence of a separate Starship build effort to the east.

SpaceX readies Starship Flight 14 for a historic journey into uncharted territory

SpaceX finished Starship’s Flight 14 rehearsal, clearing the way for its first orbital flight Monday.

SpaceX has cleared one of the last hurdles before Starship’s first trip to orbit. The company posted on X Thursday afternoon that its launch rehearsal for Flight 14 was complete, keeping the mission on track for Monday, September 28. The launch window opens at 7:15 a.m. CT at Starbase, Texas, and runs for 75 minutes.

A wet dress rehearsal is essentially launch day without the launch. Crews fill Booster 21 and Ship 41 with thousands of tons of extremely cold propellant, run the countdown nearly to ignition, then drain everything back out. It lets engineers catch leaks or equipment problems before anything leaves the pad. SpaceX still needs a launch license from the FAA before the stack, which stands 407 feet tall, can fly.

Flight 14 matters because of where it is going. All 13 previous Starship flights followed a suborbital path, which works like throwing a ball extremely high and far: the vehicle reaches space, but it is always on a course that brings it back down within about an hour. This time, Ship 41 will perform a short engine firing called an orbital insertion burn roughly 25 minutes after liftoff, giving it enough speed to keep falling around Earth instead of back into it. SpaceX plans about six laps at an altitude near 275 kilometers (171 miles) over nearly 10 hours, as Teslarati detailed when the mission was first announced.


Getting into orbit also means Starship has to prove it can get back out. The ship must relight a single Raptor engine in space to slow down for reentry. SpaceX says it will only attempt the orbital insertion burn after flight controllers confirm the hardware needed for that return burn has enough backup, and its flight plan includes health checks that could shorten the mission to two or five orbits.

Flight 14 is also the first to put working satellites into service. Flight 13 carried 20 Starlink V3 satellites in July, but they came back down with the ship because that mission never reached orbit. This time, 26 V3 satellites are meant to stay up and join the constellation within a few weeks. Together they add about 26 terabits per second of network capacity, which SpaceX says is roughly 10 times what a single Falcon 9 launch of older V2 Mini satellites adds. Three of them carry cameras that will photograph Starship’s heat shield in orbit to check for tile damage before reentry.

The hardware has changed too. Ship 41 flies with extra fasteners on tiles in the most vulnerable areas, fixes for gaps where superheated plasma slipped behind tiles, and curved tiles designed to reduce heating between them. Two tiles recovered from Ship 40 will fly again, the first reuse of any part of a Starship heat shield. Booster 21 carries better engine filtering and new relight software after ice clogged three center engines on the previous booster, leaving only eight of 13 engines to restart for its landing burn.

Ship 41 is targeting a splashdown in the Pacific Ocean west of Chile, a new recovery zone after several Indian Ocean landings, while Booster 21 aims for the Gulf. Neither will be caught by the tower on this flight. Elon Musk said in August that a ship catch was likely “in a few months.”

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

Published

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.

On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.

At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.

The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.

One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.

Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.

On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.

Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.

It is arguably as important as the software that drives it.
