SpaceX closes in on West Coast Starlink launches with lease for drone ship dock space
Amid a major hiring push and calls for monthly launches, SpaceX has taken its latest step towards launching Starlink satellites from the West Coast with a lease for rocket recovery ship dock space at the Port of Long Beach.
News of the port lease broke on April 26th with a tweet from the mayor of Long Beach, California after the Port of Long Beach (POLB) Commission voted to approve SpaceX’s 24-month sublease with an effective start date of May 1st, 2021. From 2014 to 2020, a massive floating rocket launch complex and associated service ships once used by SeaLaunch called POLB’s Pier 16 home while mothballed and the company left behind a decent amount of infrastructure when it vacated the facility last year.
That includes a ~5600 square meter (~65,000 sq ft) warehouse and office space formerly used to process SeaLaunch payloads and Ukrainian Zenit rockets, as well as a pier and dock space generally optimized for loading and unloading large rockets from rocket transport ships. In other words, Pier 16 is a perfect fit for SpaceX’s needs.
The news came as a surprise because SpaceX already has a lease for several berths and dock space at Port of San Pedro, which – along with Port of Long Beach – makes up the greater Port of Los Angeles. SpaceX has used those facilities for the better part of a decade – initially to support Dragon spacecraft recoveries but later as a hub for drone ship Just Read The Instructions (JRTI) and fairing recovery ship Mr. Steven (later Ms. Tree).
SpaceX has a bit of a sordid history with port leases over the last several years after twice entering and backing out of Port of Los Angeles (San Pedro) lease agreements to build a Starship factory directly on the water in 2018 and 2020. This time around, POLB commission documents indicate that this new lease is not the third in a line of ill-fated Starship factory plans – but instead a simple relocation of existing West Coast Falcon rocket recovery operations just two miles east of their current home.
It’s unclear why exactly SpaceX is leasing much larger berth and dock space at a port in competition with its current Port of Los Angeles landlord or if Pier 16 will be an addition to – or a replacement for – its current berths to the west. At approximately $100,000 per month, Pier 16 will be substantially more expensive, ruling out cost savings, which could mean that SpaceX has reason to believe that its West Coast rocket recovery operations are going to experience a substantial uptick in activity in the near future.
Indeed, in retrospect, SpaceX’s current Port of San Pedro berths and dock space have always been fairly limited, offering just enough space for a few small tents on concrete and a drone ship and two support vessels to park end to end. Assuming SpaceX moves all operations to Pier 16 and closes out its San Pedro lease, the new facilities should offer a bit more dock space along the pier itself, as well as far more room – and an existing warehouse with offices – to process recovered Falcon boosters and fairings.
Over half a decade of operations, SpaceX recovered Falcon boosters with drone ship JRTI just seven times (of eight attempts) on the West Coast, making it clear why the company simply chose to make do with close quarters and a barebones dockside setup. Now, however, SpaceX appears to be preparing its Vandenberg Air Force Base (VAFB) launch site and associated Port of LA recovery assets for a far more ambitious period of Falcon 9 launch activity.
Other observations support that conclusion. Over the last six or so months, SpaceX has been aggressively hiring to fully outfit its VAFB SLC-4 launch pad after supporting just two West Coast launches in the last ~28 months. Most notably, hiring ‘flyers’ distributed on social media by SpaceX employees touted a target of monthly launches from the company’s West Coast pad – an unprecedented cadence over the decade SpaceX has leased it.
First reported by Spaceflight Now, SpaceX President and COO Gwynne Shotwell recently revealed that the company intends to begin dedicated polar Starlink launches from Vandenberg as early as this summer – July 2021 if taken literally. Other “industry officials” reportedly corroborated those plans.
With its hiring campaign finally starting to slow down and a new Port of Long Beach lease set to open on May 1st, the only real ‘missing link’ for SpaceX’s plans to restart regular West Coast Falcon 9 launches is the fleet of ships the company will need to recover Falcon boosters and payload fairings. To maximize efficiency, dedicated polar Starlink launches will require Falcon 9 boosters to land far downrange and will be even more challenging than the rocket’s now-routine missions to low Earth orbit (LEO), which require almost every ounce of performance the rocket can give.
SpaceX transported its second drone ship – Just Read The Instructions (JRTI) – across the Panama Canal from Port of LA to Port Canaveral, Florida in 2019, where it still operates today. To achieve SpaceX’s planned cadence of up to 48 launches in 2021, the company will almost certainly need both drone ships on the East Coast. A third drone ship – named A Shortfall Of Gravitas (ASOG) – has been in the works for years, though SpaceX CEO Elon Musk has long described the vessel as an addition to the company’s Florida fleet that would enable Falcon Heavy to land all three first-stage boosters at sea for maximum payload capacity.
For now, we’ll just have to wait and see if SpaceX intends to send that third drone ship directly to California to support an imminent series of polar Starlink launches.

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.
