SpaceX’s backup Dragon launch pad on track for 2023 debut
SpaceX has begun building a backup launch pad for its Cargo and Crew Dragon spacecraft and says the facility could be ready for use as early as fall 2023.
Reuters first revealed those plans in June 2022. They arose because NASA reportedly told SpaceX it was worried that the company’s first Florida Starship launch site – colocated at the only pad currently able to launch SpaceX Dragon spacecraft – could add too much risk. In September 2022, NASA and SpaceX acknowledged plans to modify LC-40 for Dragon launches and indicated that both parties had decided to proceed.
Four months later, SpaceX and NASA have provided another press conference update. Officials confirmed that construction is already partially underway and reported that LC-40 could be ready to support its first Dragon launch less than a year from now.

Because Boeing’s comparable Starliner capsule is years behind schedule and still unqualified to launch humans, NASA has relied almost exclusively on SpaceX’s Crew Dragon to launch its astronauts to the International Space Station (ISS) since 2020. Starliner should be ready to supplement Crew Dragon’s operational astronaut launches by the end of 2023 or early 2024, alleviating some of that pressure.
NASA, however, chose to develop two spacecraft to guarantee that one spacecraft would likely be available if the other was grounded for any reason. Adding the possibility that a giant, new, experimental rocket (Starship) could potentially halt all SpaceX Dragon launches in one fell swoop was apparently one bridge too many for the agency.
SpaceX’s answer to the problem was about as simple, elegant, and cheap as possible. The company has two operational Falcon launch pads in Florida, and it proposed to modify the second pad. SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad is located on a secure military base and has an even longer history of successful Falcon 9 launches than Pad 39A. It also appears that its layout will allow SpaceX to add a Dragon access tower without requiring major redesigns or months of downtime.
LC-40 is SpaceX’s most productive launch pad by far, and the company intends to launch up to 100 times in 2023. It’s thus crucial that the pad remains as active as possible as it’s modified – a major challenge. A combination of luck and the fact that the launch pad is already operational is the only reason that’s possible.
Modifying SpaceX’s busiest pad
In theory, SpaceX needs to do relatively little to enable Dragon launches out of LC-40. Dragon spacecraft are processed for flight at a separate facility and only head to the pad once they’re ready to be attached to a Falcon 9 rocket. The biggest modification LC-40 needs is a launch tower, but SpaceX ironically has experience building giant towers in sections – and offsite – through Starship.
LC-40’s Dragon access tower requires far less complex plumbing and should be smaller and easier to prefabricate and assemble. Regulatory documents indicate that the new tower will stand 81 meters (265 feet) tall – almost a third shorter than the 110-meter-tall tower SpaceX modified at Pad 39A for the same purpose. LC-40 will also need a swinging access arm to connect the tower to Dragon’s hatch. That arm can also be constructed offsite, further reducing the amount of downtime required.
The most disruptive modifications may involve LC-40’s transporter/erector (T/E) device, which rolls Falcon 9 out to the pad, raises it vertical, holds it down with giant clamps; and hosts a maze of plumbing that fuels, pressurizes, and powers the rocket. The top of LC-40’s T/E is fitted with a brace designed to support Falcon payload fairings. In comparison, 39A’s T/E was designed with swappable ‘heads’ that allow SpaceX to switch between Dragon and fairing configurations in a matter of days. The top of LC-40’s T/E also appears to be somewhat removable, but SpaceX may still have to halt launches for a few weeks to get the T/E up to spec and modified for Dragon.
SpaceX says that LC-40 will be ready to support its first Dragon launch as early as fall (Q4) 2023. Its first Dragon mission will carry cargo to the ISS, meaning that the tower, arm, and pad will not need to be immediately human-rated. In theory, SpaceX could even launch Cargo Dragon 2 from LC-40 without a tower or arm, as the only purpose of the tower during uncrewed missions is to load volatile cargo at the last possible second. SpaceX could even revert to a practice that dates back to its original Dragon 1 spacecraft and devise a method to late-load cargo while Falcon 9 and Dragon are still horizontal.
The tower and access arm are only essential for Crew Dragon launches, during which astronauts must board the spacecraft a few hours before liftoff. More importantly, the same arm and tower would be used to escape Dragon and Falcon 9 in case of a minor emergency. NASA requires an escape (egress) system to human-rate a launch pad and rocket. SpaceX met that requirement at Pad 39A with a “slidewire basket” system that carries astronauts to a concrete bunker several hundred feet away from the rocket. Before LC-40 can be human-rated, SpaceX will likely need to build the same basket-and-bunker system or come up with a viable alternative.
Once complete, SpaceX will have two pads capable of supporting all Crew and Cargo Dragon launches. With that redundancy in place, NASA should be far more open to regular launches of SpaceX’s next-generation Starship rocket out of Pad 39A. Access to multiple pads will likely be essential for Starship to complete NASA’s Human Landing System (HLS) contracts, which will culminate in the giant rocket sending humans back to the Moon for the first (and second) time in half a century in the mid-to-late-2020s.

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.
