SpaceX’s Crew Dragon astronaut mission officially extended by NASA
With less than a month to go before NASA’s first crewed launch in nearly a decade, the space agency is still mulling over the details. On May 27, Bob Behnken and Doug Hurley will strap into their Crew Dragon spacecraft and blast off towards the International Space Station. During their stay, the duo will assist fellow NASA astronaut, Chris Cassidy, in maintaining the station as well as conducting several research experiments.
But how long the duo will remain on the station is still up in the air. NASA held a series of briefings on Friday, May 1, detailing the historic mission and how it would work. Hurley and Behnken will launch from Pad 39A at Kennedy Space Center at 4:32 p.m. EDT (20:32 UTC), and dock with the space station 24 hours later.
The exact length of that mission will be determined during their time in space. “It is a trade-off,” Kirk Shireman, NASA ISS program manager said during the news briefing, “between getting the spacecraft back quickly to complete its certification and providing additional crew time on the station for maintenance and research.”
The Demo-2 mission is a test flight. NASA and SpaceX will be using the mission to certify the Crew Dragon spacecraft for regular use to and from the station. So during this flight, the crew will try their hands at manual control and will test and monitor on boars systems during the significant phases of flight: launch, on orbit, and during re-entry.
Once the vehicle has completed its objectives successfully, it will be certified for a crewed flight. Currently, SpaceX is nearing completion on the next Dragon spacecraft, which will ferry four astronauts to the station for a long-duration mission. During the news briefings, SpaceX COO Gwynne Shotwell announced that the spacecraft for that mission is nearing completion and should arrive in Florida in the next couple of months.
Shireman said that the length of the Demo-2 mission was directly tied to that vehicle’s progress. “What we would like to do, from a station perspective, is to keep them on orbit as long as we can until that Crew-1 vehicle is just about ready to go, bring Demo-2 home, allow that certification work to be completed and launch Crew-1,” he said.
Steve Stich, NASA’s deputy manager of the commercial crew program, said that at minimum, the DM-2 crew would stay on orbit about a month. Their maximum stay would be no more than 119 days, due to the potential degradation of the Dragon spacecraft’s solar panels.
Solar panels are how spacecraft get their power while on orbit, and the sensitive components within the hardware degrade over time thanks to the harshness of the space environment. While it’s on orbit, ground control teams will “wake up” the spacecraft once a week to perform health checks and test the solar array’s performance.
“We would like to fly a mission that is as long as we need to for a test flight, but also support some of the space station program needs,” Stitch said.
Originally, Behnken and Hurley were expected to have a much shorter time on orbit. However, NASA officials said they started to explore the possibility of extending their mission six months ago to ensure there were enough astronauts onboard the space station to keep the orbital outpost in top shape. This year the agency is celebrating 20 years of continuous human presence on the space station, and NASA would like to ensure its continuation into the future.
To that end, Behnken and Hurley have spent significant time training to refresh themselves on station systems as well as prepare the potential spacewalks. A new shipment of batteries is scheduled to arrive on station a few days before Behnken and Hurley, and it’s possible that Behnken could be asked to conduct a spacewalk, along with Chris Cassidy.
The top priority for Behnken and Hurley will be to thoroughly check out the Crew Dragon’s systems, followed closely by relieving Chris Cassidy. “There’s a lot of work and activity that can be done in the U.S. segment; certainly more than one person can accomplish on their own,” Behnken explained during a later briefing.

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.
