SpaceX completes Falcon 9 test fire, space station supply mission up next
After almost exactly 15 months of dormancy, SpaceX’s Launch Complex 40 (LC-40) came to life with the roar of nine Merlin 1D rocket engines as Falcon 9 1035 conducted its second pre-launch static fire in preparation for the company’s 13th Commercial Resupply Services mission, CRS-13. Previously tasked with the launch of the CRS-11 Cargo Dragon, the booster completed its mission and returned safely to Landing Zone-1 (LZ-1) on June 3 2017. The path towards LC-40’s reactivation has delayed the launch approximately one week, but December 6th’s successful static fire bodes well for the current launch date, 11:46 AM on December 12.

On September 6 2016, LC-40 was effectively destroyed over the course of the Amos-6 failure. In months that followed, SpaceX reactivated LC-39A in order to continue chipping away at the company’s launch manifest, but also began the slow process of damage assessment and reconstruction of LC-40. It is safe to assume that almost every single component of the ground support equipment (GSE) was completely replaced, and interviews with Cape Canaveral’s 45th Space Wing commander suggest that SpaceX went further still, transforming the painful situation into an opportunity.
In an exclusive and frank conversation between Brig. Gen. Wayne Monteith and Florida Today’s Emre Kelly, the commander suggested that extensive design changes and additional hardening measures implemented during reconstruction are expected to make LC-40 exceptionally resilient to the rigors of rocket launches. Most tellingly, if perhaps overly optimistic, Monteith estimated that a second vehicle failure on the order of Amos-6 might only take two months to recover from, compared to the 15 months that followed Amos-6. He attributed this claim to GSE that is now largely buried underground, theoretically protecting the vast apparatus of hand-welded piping necessary to fuel the Falcon 9 launch vehicle. The replacement Transporter/Erector/Launcher (TEL) tasked with supporting Falcon 9 during integration and launch also appears to have been modernized, and will likely end up looking quite similar to the monolithic white TEL that resides at LC-39A.

With CRS-13’s static fire now complete, the mission is set to become the fifth operational reuse of a flight-proven Falcon 9 booster in 2017, thanks to NASA’s unusually rapid acceptance of the new practice. Further still, if Iridium-4’s December 22 launch date holds, and it does look to be stable for the moment, SpaceX will rather incredibly have conducted five commercial reuses of a Falcon 9 in its first year of operations, meaning that one third of SpaceX’s 2017 missions will have launched aboard flight-proven boosters. Also impressive is SpaceX’s full-stop move towards the reuse of Cargo Dragon capsules, and the company stated over the summer that it was hoping to almost completely redirect Cargo Dragon’s manufacturing facilities towards Dragon 2, also known as Crew Dragon. This was most recently reiterated several months ago and is presumed to still be the company’s goal moving forward, and CRS-12 is believed to have been the last “new” Cargo Dragon that will fly. CRS-13’s Dragon previously flew the CRS-6 mission in April 2015.

In a December 6 tweet, SpaceX further confirmed that the deeply secretive Zuma mission, previously delayed from an early-November launch as a result of concerns about fairing defects, has now been moved from LC-39A to LC-40 and is understood to be targeting January 4 2018. This will give SpaceX approximately three weeks after the launch of CRS-13 to verify that everything is functioning nominally in what is essentially a new pad.
Meanwhile, with Zuma now officially moved to 40, LC-39A is completely free from routine operations, meaning that SpaceX’s ground crew can now work at will to ready the pad for the inaugural launch of Falcon Heavy, now aiming for early 2018. Aside from Falcon Heavy, recent FCC filings point to two additional SpaceX launches aiming for January, although slips are probable in light of CRS-13’s minor delays. Regardless, December and January are likely to be thrilling months for followers of the intrepid space exploration outfit.

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.
