SpaceX installs second Starship-derived fuel tank at orbital launch pad

This is getting out of hand, now there are two of them! (NASASpaceflight - bocachicagal)

For the second time in two weeks, SpaceX has rolled a ‘Starship-derived’ propellant tank to the next-generation rocket’s first orbital launch pad, continuing a recent burst of construction activity.

Precisely two weeks ago, SpaceX rolled the first of those massive ground support equipment (GSE) propellant tanks the 1.5 miles from its Boca Chica rocket factory to a nearby launch complex. Built with the same parts, facilities, and equipment as flightworthy Starship prototypes, SpaceX’s plans to build grounded storage tanks out of rocket parts went from a complete surprise to initial hardware delivery in less than two months.

Two weeks later, SpaceX has already completed the second of at least seven similar or identical tanks that should be able to store enough propellant for two back-to-back orbital Starship launches – and a third ‘GSE’ tank is just a week or so behind it.

As previously discussed on Teslarati, SpaceX’s decision to use a literal rocket factory to build custom propellant storage tanks is surprisingly revealing with a few reasonable assumptions in place.

SpaceX is effectively taking interchangeable Starship parts, slightly tweaking a handful of them, and turning what could have been a rocket into a propellant storage tank. This is significant because relative to all other rockets in history, even including SpaceX’s own Falcon 9 and Heavy, building storage tanks with unchanged rocket parts on a rocket assembly line would be roughly akin to hiring Vincent van Gogh to paint lane lines.

The existence of self-built propellant storage tanks virtually identical to flightworthy Starship airframes all but guarantees that SpaceX is already building Starships for a few million dollars each – and possibly much less.“

Aside from potentially being dirt-cheap bulk storage tanks that all but guarantee SpaceX can produce Starship and its Super Heavy boosters for pennies on the dollar of any other rocket in history, SpaceX is quickly demonstrating that it can build a lot of them – and quickly. Parts of Starship prototypes SN17 through SN20 and Super Heavy boosters BN2 and BN3 continue to slowly trickle out of SpaceX’s factory and Starship SN16 is steadily progressing towards completion to take over wherever SN15 leaves off.

However, at least a majority of SpaceX’s focus appears to be set on mass-producing propellant storage tanks as quickly as possible in order to prepare Starship’s orbital launch pad – deep into construction – for flight tests involving Super Heavy. Just last month, following a sourced report from NASASpaceflight.com, CEO Elon Musk confirmed that SpaceX intends to attempt Starship’s first launch on a Super Heavy booster as early as July 2021 – just three months from now.

For obvious reasons, the odds are firmly stacked against SpaceX attempting Starship’s first orbital launch mere months from now, though such an attempt would still be extremely impressive if it happens in 2021 at all. To even attempt that extraordinarily ambitious feat, SpaceX will have to complete at least a barebones ‘rough draft’ of its planned orbital launch complex, including at least four Starship-style GSE tanks.

Towards that end, GSE tank #3 (GSE-3) is already more than half complete and parts of GSE-4 are in work, likely meaning that SpaceX will have enough installed propellant storage capacity for orbital Starship launch attempts less than a month from now. It remains to be seen if SpaceX will power through tanks 5 through 7 after 3 and 4 are complete, or if the focus will shift back to Starship and Super Heavy prototype production.

Either way, SpaceX is wasting no time constructing a brand new super heavy-class launch pad and a tank farm the likes of which has never been seen before. For now, we’ll have to wait and see how long it takes Starship and Super Heavy to catch up.

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.

Published

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.

Tesla leaks Semi customers ahead of handover event

Tesla is set to inaugurate its dedicated Semi factory in Sparks, Nevada, this evening, but drone footage has already started to show who is expected on the handover stage.

Zanegler, a drone operator who regularly documents Tesla Semi operations in Nevada, filmed a row of new-generation Semi units parked outside of the plant with customer branding applied. The liveries visible in the video include companies like PepsiCo, U.S. Foods, Einride, DHL, WattEV, and others that have committed to utilizing Tesla’s Class 8 electric truck in their fleets.

Several of those company names already sit within Tesla’s public ordering book, including PepsiCo, which has been the program’s primary anchor customer since the first Semi deliveries in December 2022. PepsiCo now runs dozens of Tesla Semi units in daily service, with drivers completing regional routes.

Einride placed a 500-unit order in August, which was, at the time, the largest single Semi commitment. First deployments of their Semi units are planned for this month and will eventually span across California, Texas, New Jersey, Illinois, and Georgia. Meanwhile, IMC Logistics announced a 50-truck California order this week.

Tesla Semi lands the biggest electric truck deal in U.S. history

Other names, like LTS, OK Produce, and HMD, have not been widely confirmed as firm buyers, but their presence on the lot is perhaps the clearest signal that Tesla intends to expand on that list this evening at the event.

Tesla first unveiled the Semi back in 2017 with a 2019 production target.

Limited pilot builds reached PepsiCo in late 2022, and high-volume production began at the new 1.7-million-square-foot plant that sits logically positioned next to Tesla’s Gigafactory Nevada. Tesla Semi program director Dan Priestley has said that Tesla expects to build “many thousands” of Semi units this year, but as with every Tesla release, there have been set expectations of an S-curve ramp.

Outside estimates still put 2026 deliveries in the 5,000-to-15,000 range, but it will ultimately depend on Tesla’s readiness to put those units out, as well as how smoothly production is moving internally.

Tesla’s Semi Rollout event is set to start tonight at the Sparks factory, and it will be livestreamed on X starting at 6 p.m. PDT / 9 p.m. ET.
