SpaceX begins building upgraded Starship prototype
A Starship part spotted on July 20th confirms that SpaceX is already well into the process of building a significantly upgraded full-scale prototype.
Following in the footsteps of five or six full-scale ships before it, information published by NASASpaceflight.com suggests that Starship SN8 will be a substantial departure from its predecessors. Thanks to data gathered by testing the Starship SN7 test tank to destruction on June 24th, SpaceX has determined that a different alloy – known as 304L – is superior to the 301 stainless steel all Starship prototypes have been built out of up to now.
SN8 is SpaceX’s response to that discovery. As usual, the company has performed smaller tests before deciding to build a full-scale Starship prototype – identical to all previous SNx prototypes beyond the alloy change – out of 304L stainless steel. As a result, Starship SN8 – once complete – may have the most potential of any prototype built thus far, but its fate will also be more uncertain than most of its predecessors.
On June 24th, SpaceX destroyed the SN7 Starship test tank as part of a controlled cryogenic proof test – essentially a pressure test at cryogenic (ultra-cold) temperatures. Departing from routine, CEO Elon Musk never commented on the test, leaving its results shrouded in mystery. According to NASASpaceflight, however, SN7 “achieved a record pressure before it failed.”
Designed to test a different formulation of stainless steel, that success implies that SN7 proved that the 304L alloy will not only be more malleable and forgiving at cryogenic temperatures – but is also more capable overall compared to 301 steel. To beat the record set by the second or third Starship test tank in January or March 2020, SN7 would have had to reach pressures of ~8.6 bar or higher – effectively icing on the cake for the already-demonstrated ~140% safety factor.
A full-scale Starship has yet to survive proof tests at those pressures but Starship SN4 did become the first to complete a full cryo proof, sustaining ~7.5 bar (~110 psi) before it was safely depressurized. Currently on the pad and preparing for an imminent static fire and hop test debut, Starship SN5 is unlikely to put pressure on that record unless that it aces both of the aforementioned trials. Built entirely out of the 304L alloy already proven to be superior to 301, SN8 may well be the golden goose of prototypes.
“The vehicle will feature major upgrades over previous Starship prototypes. SN8 will be built out of 304L stainless steel versus 301 and will receive a fairing, aerosurfaces, and three Raptor engines to allow for a higher-altitude test flight.”

The appearance of SN8’s labeled common dome – the dome separating Starship’s liquid oxygen and methane tanks – implies that a variety of other parts spotted over the last few days are also meant for the next full-scale rocket. Mounted on a stand purpose-built for the task, the SN8 common dome will soon be ‘sleeved’ by one or several stacked steel rings, after which it can be welded to the rest of the Starship’s tank. An engine section and thrust structure – likely SN8’s – in the late stages of assembly was spotted three days prior, while an upper tank dome that could be for either SN8 or test tank SN7.1 was captured in the same photos.
In the last photo, taken on July 13th, there’s even signs of what could be Starship SN9 – hinted at by the appearance of two Starship engine sections signified by the pattern of welds on their exteriors. Those welds are incontrovertible signs of the stringers used to strengthen Starship engine sections and they haven’t been used anywhere else on past prototypes.
Based on the sheer number of steel rings and domes currently floating around SpaceX’s Boca Chica, Texas Starship factory, SN8 could be a just a week – or even less – away from final stacking operations. If SN5 leaves the pad intact and completes its wet dress rehearsal, static fire, and flight debut without issue, SN8 could be up to bat much sooner than later.

Elon Musk’s xAI celebrates nearly 3,000 headcount at Memphis site
The update came in a post from the xAI Memphis account on social media platform X.
xAI has announced that it now employs nearly 3,000 people in Memphis, marking more than two years of local presence in the city amid the company’s supercomputing efforts.
The update came in a post from the xAI Memphis account on social media platform X.
In a post on X, xAI’s Memphis branch stated it has been part of the community for over two years and now employs “almost 3,000 locally to help power Grok.” The post was accompanied by a photo of the xAI Memphis team posing for a rather fun selfie.
“xAI is proud to be a member of the Memphis community for over two years. We now employ almost 3,000 locally to help power @Grok. From electricians to engineers, cooks to construction — we’re grateful for everyone on our team!” the xAI Memphis’ official X account wrote.
xAI’s Memphis facilities are home to Grok’s foundational supercomputing infrastructure, including Colossus, a large-scale AI training cluster designed to support the company’s advanced models. The site, located in South Memphis, was announced in 2024 as the home of one of the world’s largest AI compute facilities.
The first phase of Colossus was built out in record time, reaching its initial 100,000 GPU operational status in just 122 days. Industry experts such as Nvidia CEO Jensen Huang noted that this was significantly faster than the typical 2-to-4-year timeline for similar projects.
xAI chose Memphis for its supercomputing operations because of the city’s central location, skilled workforce, and existing industrial infrastructure, as per the company’s statements about its commitment to the region. The initiative aims to create hundreds of permanent jobs, partner with local businesses, and contribute to economic and educational efforts across the area.
Colossus is intended to support a full training pipeline for Grok and future models, with xAI planning to scale the site to millions of GPUs.

Ford embraces Tesla-style gigacastings and Cybertruck’s 48V architecture
Ford Motor Company’s next-generation electric vehicles will adopt technologies that were first commercialized by the Tesla Cybertruck.
Ford Motor Company’s next-generation electric vehicles will adopt technologies that were first commercialized by the Tesla Cybertruck, such as the brutalist all-electric pickup’s 48-volt electrical architecture and its gigacastings.
The shift is expected to start with a roughly $30,000 small electric pickup that is expected to be released in 2027, which is part of Ford’s $5 billion investment in its new Universal EV platform, as noted in a CNBC report.
Ford confirmed that its upcoming EV platform will move away from the traditional 12-volt system long used across the auto industry. Instead, it will implement a 48-volt electrical architecture that draws power directly from the vehicle’s high-voltage battery.
Tesla was the first automaker to bring a 48-volt system to U.S. consumers with the Cybertruck in 2023. The architecture reduces wiring bulk, lowers weight, and improves electrical efficiency. It also allows power to be stepped down to 12 volts through new electronic control units when needed.
Alan Clarke, Ford’s executive director of advanced EV development and a former Tesla engineer, called 48-volt systems “the future of automotive” due to their lower costs and smaller wiring requirements. Ford stated that the wiring harness in its new pickup will be more than 4,000 feet shorter and 22 pounds lighter than that of its first-generation electric SUV.
Apart from the Cybertruck’s 48-volt architecture, Ford is also embracing Tesla-style gigacastings for its next-generation EVs. Ford stated that its upcoming electric vehicle will use just two major structural front and rear castings, compared with 146 comparable components in the current gas-powered Maverick.
Ford CEO Jim Farley has described the effort as a “bet” and a “Model T moment” for the company, arguing that system-level innovation is necessary to lower costs and compete globally. “At Ford, we took on the challenge many others have stopped doing. We’re taking the fight to our competition, including the Chinese,” Farley previously stated.

Tesla meets Giga New York’s Buffalo job target amid political pressures
Giga New York reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease.
Tesla has surpassed its job commitments at Giga New York in Buffalo, easing pressure from lawmakers who threatened the company with fines, subsidy clawbacks, and dealership license revocations last year.
The company reported more than 3,460 statewide jobs at the end of 2025, meeting the benchmark tied to its dollar-a-year lease at the state-built facility.
As per an employment report reviewed by local media, Tesla employed 2,399 full-time workers at Gigafactory New York and 1,060 additional employees across the state at the end of 2025. Part-time roles pushed the total headcount of Tesla’s New York staff above the 3,460-job target.
The gains stemmed in part from a new Long Island service center, a Buffalo warehouse, and additional showrooms in White Plains and Staten Island. Tesla also said it has invested $350 million in supercomputing infrastructure at the site and has begun manufacturing solar panels.
Empire State Development CEO Hope Knight said the agency was “very happy” with Giga New York’s progress, as noted in a WXXI report. The current lease runs through 2029, and negotiations over updated terms have included potential adjustments to job requirements and future rent payments.
Some lawmakers remain skeptical, however. Assemblymember Pat Burke questioned whether the reported job figures have been fully verified. State Sen. Patricia Fahy has also continued to sponsor legislation that would revoke Tesla’s company-owned dealership licenses in New York. John Kaehny of Reinvent Albany has argued that the project has not delivered the manufacturing impact originally promised as well.
Knight, for her part, maintained that Empire State Development has been making the best of a difficult situation.
“(Empire State Development) has tried to make the best of a very difficult situation. There hasn’t been another use that has come forward that would replace this one, and so to the extent that we’re in this place, the fact that 2,000 families at (Giga New York) are being supported through the activity of this employer. It’s the best that we can have happen,” the CEO noted.
