Elon Musk says SpaceX could build new Moon spacesuits for NASA
A new report from NASA’s Office of the Inspector General (OIG) strongly suggests that spacesuit availability, of all things, could prevent NASA from returning humans to the Moon on schedule in 2024.
Days prior, a similar watchdog office (GAO) denied protests from Blue Origin and Dynetics that were preventing NASA and SpaceX from working on the Starship-derived lander that will land those same humans on the Moon. Now, in an indirect response to NASA OIG’s analysis of the status of NASA’s next-generation spacesuit procurement efforts, CEO Elon Musk says that SpaceX may be able to provide its own custom Moon-rated spacesuits on top of a Starship lander.
As it turns out, SpaceX is already one of around two dozen “interested parties” [PDF] active in NASA’s new xEVAS (Exploration Extravehicular Activity Services) program – an effort to commandeer the spectacular success of commercial cargo and crew programs to replace half-century-old spacesuits. xEVAS has currently released a draft Request for Proposal (RFP) and is awaiting responses to that draft until mid-August before releasing the true RFP in mid-September.
Interested parties will then have until mid-October to submit proposals to design and build modern EVA (extravehicular activity) spacesuits capable of supporting astronauts on the lunar surface and on spacewalks in Earth orbit. NASA says it will then take a full five (or seven) months to review those proposals, downselect, and reward at least one or two contracts – hopefully resulting in two redundant EVA systems much like the 2+ redundant providers NASA chose to support its Commercial Crew (CCP) and Cargo Resupply Services (CRS) programs.
Over the last decade and a half, NASA has been very gradually working on its own next-generation EVA suits. Known as “xEMU,” the program has been less than smooth, running into multiple issues, funding shortfalls, and delays over the years. NASA OIG’s August 10th, 2021 report [PDF] says that the minimum two xEMU suits needed to support a planned crewed Moon landing as early as 2024 are almost certainly not going to be ready by 2024 after COVID-19, funding shortfalls, and technical difficulties recently delayed the program by almost two years. The office estimates that those NASA-built EVA suits will be ready absolutely no earlier than April 2025.
However, in April 2021, NASA kicked off its brand new xEVAS program – a program that strongly implies that the agency is all but giving up on building its own xEMU EVA suits. While it appears that the agency still plans to build six of its own xEMU suits as a hedge against its innovative, unprecedented xEVAS EVA-suits-as-a-service program, there’s a chance that NASA’s prospective commercial providers could help mitigate or outright prevent spacesuit availability from delaying humanity’s return to the Moon.
Of course, with NASA set to award xEVAS contracts no earlier than either March or May 2022, providers would be left with a mere ~30 months to design, prototype, build, and qualify what amount to personal human-rated spacecraft (EVA suits). According to NASA, “the goal is to achieve one or more EVA service demonstrations as early as 2024, and the full suite of commercial EVA services beginning as soon as feasible thereafter” – an extraordinarily ambitious target.
Notably, for its spectacularly successful Crew Dragon program, SpaceX has already developed and repeatedly flown a custom pressure suit for Dragon astronauts. That IVA suit is designed to keep astronauts alive in the event of spacecraft depressurization. Due to the mobility they must provide and a resultant need for light and portable power and life support systems, EVA suits are dramatically more complex than IVA suits, which offer very little mobility when fully pressurized and are permanently connected to their spacecraft through umbilicals.
If anyone can rise to the challenge of developing an EVA suit from scratch in two years, though, it’s likely SpaceX.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
