SpaceX Dragon XL could double as a crew cabin for lunar space station
A recent modification to SpaceX’s Dragon XL lunar cargo resupply contract with NASA suggests that the spacecraft could be used as an extra crew cabin and bathroom at a lunar space station known as Gateway.
The contract modification was made around April 1st of this year and provided SpaceX around $121,000 to complete the latest study on the potential utility of its expendable Dragon XL spacecraft beyond the primary goal of resupplying a space station orbiting the Moon. Designed to deliver at least five metric tons (~11,000 lb) of pressurized and unpressurized cargo to Gateway, Dragon XL will launch on SpaceX’s own Falcon Heavy rocket – currently the only super heavy-lift launch vehicle in operation – and meant to heavily borrow from hardware and systems already developed for Crew and Cargo Dragon.
NASA first announced its selection of SpaceX for the Gateway Logistics Services (GLS) contract back in March 2020. More than a year later, very little has been said (or visibly done) to progress from that announcement to a true contract – an unusually long period of inactivity for such a significant program.
Of note, as recently as April 2021, NASA officials made it clear that they were still in the cryptic process of “reviewing” the Artemis program, leading to such a long delay between the GLS award announcement and finalization of an actual contract with SpaceX. Of note, back when it was announced, NASA’s nominal plan was to begin Dragon XL cargo deliveries as early as 2024 to support the Artemis Program’s first crewed Moon landing attempt.
Since then, however, other crucial aspects – namely the concept of operations and Human Lander System (HLS) meant to carry astronauts to and from the Moon – have evolved significantly. Weeks after NASA’s GLS announcement, the space agency awarded approximately $1 billion to three prospective HLS providers – SpaceX, Dynetics, and a team led by Blue Origin. A little over a year later, NASA announced a shocking decision to award that initial HLS Moon landing demonstration contract to SpaceX and SpaceX alone.
More or less simultaneously, NASA it made it clear that it was seriously studying the possibility of performing Artemis-3 – the first crewed Moon landing attempt in half a century – without Gateway. Along those lines, the SLS-launched Orion spacecraft and HLS lander (a custom variant of SpaceX’s Starship) would dock directly in lunar orbit instead of separately docking to Gateway to transfer crew. NASA’s decision to solely select Starship as its future Moon lander was so surprising in large part because of how starkly the vehicle’s potential capabilities contrast with the rest of the Artemis Program.
As many have already noted, the very existence of a Starship with capabilities close to what SpaceX is working towards – now a practical inevitability for the company to complete its HLS contract – brings into question the architecture NASA has proposed for Artemis. Currently, the nominal plan is to launch astronauts into an exotic high lunar orbit with NASA’s own SLS rocket and Orion spacecraft – an inconvenient orbit only needed to make up for said spacecraft’s shortcomings. Prior to recent developments, Orion would then dock with Gateway. The HLS vehicle would follow and crew would eventually transfer to the lander, which would then carry 2+ astronauts to and from the surface of the Moon and re-dock with Gateway, followed by Orion returning those astronauts to Earth.
Given that Starship offers enough pressurized volume to rival even the vast International Space Station (ISS) in a single launch, the entire concept of Gateway – an almost inhumanely tiny space station – becomes dubious. If Orion also doesn’t need Gateway to transfer its astronauts to the lander, which NASA has all but confirmed, it’s difficult to see what value Gateway could offer outside of a very expensive technology demonstration. Including a planned Falcon Heavy launch of the first two Gateway segments, station production, and the possible need for expensive Dragon XL cargo deliveries, Gateway could easily end up costing NASA $4-5 billion before it hosts a single astronaut.
NASA is already deeply concerned about the apparent likelihood of Congress systematically underfunding the HLS and Artemis programs outside of SLS and Orion, going as far as selecting just a single HLS provider after clearly indicating a desire for redundancy given enough funding. NASA’s HLS contract with SpaceX is expected to cost around $2.9 billion. The next cheapest option – Blue Origin’s proposal – would reportedly cost around $6 billion. In other words, if NASA were able to stop work and Gateway and redirect that funding elsewhere, it could almost already afford two HLS providers without a larger budget.
Given that NASA has selected SpaceX for HLS and GLS, it’s not impossible to imagine that the space agency is growing increasingly aware that Gateway and Dragon XL look more than a little redundant beside the Starship vehicle NASA itself is now funding SpaceX to realize. For now, though, work on all three programs continue. Most recently, NASA and SpaceX are studying the possibility of adding a toilet and using Dragon XL as an extra crew cabin and bathroom to augment the tiny habitable volume of Gateway’s lone habitat. Only time will tell where the cards ultimately fall.

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.
