SpaceX installs Dragon spaceship on the rocket that’ll take it to space (again)
For the third time ever, SpaceX has installed a Crew Dragon spacecraft scheduled to launch astronauts on the Falcon 9 rocket that’ll carry it to orbit, sailing past one of the mission’s last major preflight milestones.
Known as Crew-2, the NASA Commercial Crew Program (CCP) mission will be SpaceX’s second operational crew ferry mission after its operational Crew-1 debut launched flawlessly on November 15th, 2020. Since November 16th, the Crew-1 Crew Dragon has been docked to the International Space Station (ISS) in Low Earth Orbit (LEO) – marking at least two major firsts – and won’t return to Earth until Crew-2 has safely joined it at the station.
Simultaneously developed as part of the Commercial Crew Program, a raft of technical and organizational shortcomings have extensively delayed Boeing’s Starliner crew capsule, effectively forcing NASA to lean on SpaceX to pick up the slack with multiple back-to-back Crew Dragon missions. Organizational excellence aside, Crew-2 is also on track to secure two of the most significant reusability achievements in SpaceX’s long history of significant reusability achievements.
Mere days after a SpaceX Falcon 9 rocket and Crew Dragon spacecraft lifted off with NASA astronauts aboard for the first time ever, becoming the first crewed launch in history to use a commercially-developed rocket or spacecraft, the space agency effectively gave the company permission to fly its astronauts on flight-proven versions of those same vehicles.
While those plans have effectively fallen under the radar relative to other SpaceX activities, it’s not unreasonable to say that a successful Crew-2 launch with both a flight-proven Falcon 9 booster and Crew Dragon capsule would be one of the most significant technical achievements in the company’s history. At the bare minimum, it will be the most symbolically significant achievement in SpaceX’s history.
In essence, success would mean that SpaceX has unequivocally proven that a private company can develop – from scratch – methods of rocket and spacecraft reusability that are so successful and so reliable that perhaps the most risk-averse customer on Earth is willing to place the lives of its astronauts in the hands of those flight-proven spacecraft and rockets. If SpaceX can accomplish that feat with Falcon 9 and Crew Dragon, there is no practical reason to doubt that it can be repeated with Starship – a vehicle that has already piqued NASA’s interest.
The Crew Dragon capsule assigned to Crew-2 debuted on May 30th, 2020 and carried NASA astronauts Bob Behnken and Doug Hurley to the ISS without any major issue, where it spent a little over two months in orbit. On August 2nd, the spacecraft safely reentered Earth’s atmosphere traveling around 7.5 kilometers per second (17,000 mph) and splashed down in the Gulf of Mexico with both astronauts none the worse for wear. Since then, SpaceX has disassembled the Dragon, carefully inspected every possible inch, and refurbished the vehicle for Crew-2.
Despite the historic nature of the task of qualifying and refurbishing the first commercial spacecraft in history that is expected to launch NASA astronauts twice, Crew Dragon C206’s turnaround will be the fastest in Dragon history – and by a margin of almost 40%.
After acing its role in SpaceX’s first operational astronaut launch five months ago, Falcon 9 booster B1061 will also be flying for the second time on Crew-2 – especially fitting given that the Crew-2 will meet the only other spacecraft and astronauts launched on the same booster at the ISS. As of Thursday, April 15th, Crew-2 is seven days away from a launch planned no earlier than 6:11 am EDT (10:11 UTC) on Thursday, April 22nd. The flight-proven Dragon and Falcon 9 booster and a new, expendable upper stage are expected to roll out to Pad 39A within the next few days for an integrated static fire test 4-5 days prior to launch.

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.
