SpaceX, NASA will reattempt historic astronaut launch on Saturday, May 30th
Stormy Florida weather has forced SpaceX to delay its historic NASA astronaut launch debut attempt, pushing the mission’s next attempt to Saturday, May 30th.
Unfortunately, the possibility that weather would improve forced SpaceX and NASA to wait just 16 minutes before launch to call of Crew Dragon’s Demo-2 inaugural astronaut flight test. Thankfully and far from a guarantee, every aspect under SpaceX and NASA’s control went perfectly leading up to launch, with the mission’s new Falcon 9 booster more than 70% fueled before the abort was called. As such, SpaceX’s first Demo-2 launch attempt has also served as the company’s first live wet dress rehearsal (WDR) with astronauts on top of the rocket.
The value of such a test – even if SpaceX wasn’t ultimately able to launch – is undoubtedly significant and, as SpaceX’s John Insprucker noted after the scrub, the Falcon 9 rocket and Crew Dragon spacecraft can safely perform dozens of similar launch (and abort) cycles over their lifetime. For now, SpaceX and NASA’s second such launch attempt is scheduled to occur no earlier than (NET) 3:22 pm EDT (19:22 UTC) on Saturday, May 30th.
Unfortunately, present forecasts expect weather to be only slightly more favorable on both May 30th and 31st, offering a 60% chance of favorable launch conditions and a similar focus on the same thunderstorm-related constraints. As such, there’s a definite chance that the next two attempts will also result in equivalent practice runs instead of an actual liftoff. Nevertheless, SpaceX and NASA will continue to try. For anyone that’s experienced Space Shuttle launches over the former vehicle’s three decades of operations, these kinds of weather-related scrubs – let alone the technical faults that often delayed Shuttle launches – were a constant feature of the system.
Falcon 9 and Crew Dragon are at least as sensitive to weather constraints, albeit for significantly different reasons than the Shuttle.
“For two interconnected reasons, SpaceX’s Crew Dragon astronaut missions are going to be extraordinarily sensitive to weather restrictions come launch day, a fact that has come to partially dominate the tone of Demo-2 preparations over the last few days. First and foremost, NASA’s single highest priority for crewed Commercial Crew Program (CCP) launches is and will continue to be astronaut safety.
As a direct result of SpaceX’s significant safety improvements, it and NASA are ironically going to have a more challenging time launching Crew Dragon as dozens of possible abort splashdown locations stretching across the Atlantic Ocean will have to be constantly monitored for weather violations. SpaceX Vice President of Build and Reliability Hans Koenigsmann described the method of weighing those dozens of sites as an extremely complex algorithm, suggesting that unacceptable weather in certain spots might not fully delay a launch opportunity.”

Notably, given NASA’s well-publicized concerns about SpaceX’s proposal and design decision to “load and go”, referring to the practice of boarding astronauts before the rocket begins fueling, today’s successful (unplanned) rehearsal and launch abort will hopefully be the final straw to any remaining worries. With the abort, SpaceX has fully demonstrated that it can safely ingress astronauts, clear the launch pad, load Falcon 9 with hundreds of tons of liquid oxygen and kerosene propellant, proceed through the launch count, offload that propellant, and ultimately safe the rocket and pad for crew egress.
After leaving the rocket, NASA astronauts Bob Behnken and Doug Hurley will return to astronaut processing facilities and be treated to an approximately 48-hour break before once again preparing for their second Crew Dragon launch attempt. With a little luck, forecasts will improve and skies will clear for that historic do-over over the next three days.

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.
