SpaceX Falcon 9 wins Korean launch contract as 2019 mystery missions persist
SpaceX has silently announced that Falcon 9 won a contract for a South Korean military communications satellite, currently scheduled to launch from the company’s Cape Canaveral Air Force Station (CCAFS) LC-40 pad no earlier than November 2019.
Subcontracted from Lockheed Martin to Airbus Defense and Space in 2016, the satellite – known as Anasis II (formerly KMilSatCom 1) – is based on a common bus built by Airbus and could weigh anywhere from 3500 to 6000 kilograms (7500-13,200 lb). Falcon 9 will be tasked with launching Anasis II to geostationary transfer orbit (GTO), after which the satellite will use its own onboard propulsion to circularize the orbit and begin operations. Although the Korean contract brings SpaceX one step closer to its goal of 18-21 launches (excluding Starlink) in 2019, it also raises the question: what mystery missions are missing from public launch manifests?
Manifest Mystery
As previously discussed in both Teslarati articles and newsletters, comments from SpaceX executives in February and May 2019 reiterate the company’s expectation of 18-21 launches in 2019, excluding Starlink. Hofeller’s “more than 21 launches” admittedly came more than two months before a catastrophic Crew Dragon failure threw the spacecraft’s launch manifest into limbo.
Three months later, SpaceX President and COO Gwynne Shotwell reiterated the idea that SpaceX could beat its 2018 launch record (21 launches) or at least get close. Curiously, she specifically noted that SpaceX’s purported 18-21 launch manifest excluded Starlink missions, of which SpaceX has already launched one. In short, SpaceX has completed 7 launches in 2019 (6 if Starlink v0.9 is excluded). The company’s public manifest – unofficially cobbled together by fans – shows 9 more launches scheduled for a total of 15 non-Starlink launches in 2019.
To meet Shotwell’s expected 18-21 non-Starlink launches, anywhere from 3 to 6 missions are apparently missing from publicly-managed launch manifests. It’s unclear if SpaceX actually has enough launch-ready customers to achieve those ambitious targets. Additionally, SpaceX is currently on track to complete 8 launches total (1 Starlink) in the first half of 2019. In 2017 and 2018 (two years without interruption), SpaceX consistently launched an equivalent number (or more) missions in the first half of the year when compared to the second half, and both years have maxed out at 9 launches in H2.
SpaceX will have to beat that H2 record to reach 18 launches in 2019 even if Starlink missions are counted. Meanwhile, SpaceX says that as many as 1-5 additional Starlink launches are scheduled for 2019, bringing the total number of missions as high as 20-27 in differing best-case scenarios. Practically speaking, between SpaceX’s Pad 39A and LC-40 launch facilities, the company could easily maintain a biweekly or even weekly cadence (13-26 launches in H2 2019). The real constraint, however, is hardware availability – i.e. whether SpaceX has the rocket pieces and flight-ready satellite(s) it needs to launch a given mission.
Can SpaceX do it?
This is an extremely hard question to answer, as all details that really matter are of the organizational, company-secrets sort that SpaceX just doesn’t publicize. From a technical and practical perspective, the answer is a reasonable confident “yes.” If Falcon Heavy Flight 3 (STP-2) is completed successfully, SpaceX will have an impressive fleet of at least 8 flight-proven Falcon 9-class boosters. Even assuming that no progress is made beyond the current Block 5 turnaround average of ~110 days (~3.5 months), SpaceX’s current fleet should be able to immediately support four launches and an additional 8-12 before the end of 2019.
The primary limit, then, would be SpaceX’s ability to produce Falcon 9 upper stages and fairings, as well as the stamina and quality of the company’s managers and employees. Even then, the question of SpaceX’s 3-6 mystery launches will remain unanswered until either the customer or launch provider choose to open up. For now, we wait…

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.
