SpaceX aces ninth rocket launch, eighth landing this year

Published

on

Like clockwork, SpaceX has successfully launched yet another batch of 60 Starlink satellites into low Earth orbit, racking up the company’s ninth launch (and eighth rocket landing) this year.

Set to be SpaceX’s last (orbital) launch this quarter, Starlink V1 L22’s success leaves it on track for an impressive 36 launches this year if the company can repeat the feat thrice over. That would be a third short of an ambitious 48-launch target but still smash the 26-launch record SpaceX set just last year by almost 40%.

Supporting its sixth orbital-class launch and landing in less than nine months, Falcon 9 booster B1060 sailed through boost phase, reentry, and descent without issue before sticking the landing on drone ship Of Course I Still Love You (OCISLY). Notably, every single orbital SpaceX launch this year – Starlink-22 included – has used a flight-proven booster and the first launch of a new booster is unlikely to happen before the second half of 2021.

Including a batch of 10 of the first polar Starlink satellites – also bearing space-laser prototypes – flown on a commercial rideshare mission earlier this year, Starlink-22 is technically SpaceX’s 23rd operational Starlink launch and 24th Starlink launch overall. Completed in 22 months, including all 23 operational missions in just 16 months, those two-dozen launches have delivered nearly 1400 broadband satellites to LEO.

Excluding 62 prototype Starlink satellites, 12 of which are still in orbit, less than 2% of the 1322 operational spacecraft launched have suffered some kind of issue, while a little over 1% have deorbited and burned up in Earth’s atmosphere. Assuming the Starlink-22 batch continues the positive trend, that failure rate has dropped as low as ~0.6% for the last ~890 satellites launched.

Aside from continuing what looks set to be another halcyon year of launches and Starlink milestones, Starlink-22 was also SpaceX’s fourth launch this month, making March 2021 its second four-launch month ever. That cadence – a bit less than one launch per week – is exactly what SpaceX would need to maintain to achieve the ambitious 48-launch target set by CEO Elon Musk last year.

SpaceX achieved its first four-launch month in November 2020 and repeating the feat just four months later is a strong sign that routine weekly launches are well within reach as operational efficiency continues to improve. Of all orbital rockets in history, just a few of which reached similar operational peaks sometime last century, Falcon 9 is the first in decades to get anywhere close to an annual cadence of 30-40+ launches.

SpaceX’s next launch (unsurprisingly a Starlink mission) is expected sometime in early April, followed by at least another one or two more Starlink missions before the focus shifts to Crew-2 – Crew Dragon’s third astronaut launch – around the second half of the month.

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.

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.
