SpaceX scrubs Falcon 9’s seventh-flight debut for more “mission assurance”
Update: SpaceX has scrubbed Falcon 9’s seventh-flight debut and the 14th Starlink launch this year to allow more time for “data reviews” and “additional mission assurance” and is now scheduled to launch Starlink-15 no earlier than (NET) 9:34 pm EST (02:34 UTC) Monday, November 23rd.
In a tweet shortly after the decision was made, SpaceX said that both the Falcon 9 rocket and Starlink payload were still healthy, adding a bit of mystery to the decision. On SpaceX’s official mission control audio stream, the Starlink-15 launch director (LD) – most likely Ricky Lim – announced the scrub around T-35 minutes, effectively the deadline for the start of Falcon 9 propellant loading. For whatever reason, SpaceX was not confident enough to commit to launch and LD stated that the scrub had been called to allow for “additional mission assurance” – the second time in recent memory that the company has used that particular industry euphemism.
Regardless of the reason, the first seventh flight (sixth reuse) of a Falcon 9 booster is certainly cause enough for caution, as it means that SpaceX is very literally pushing the envelope of orbital-class rocket reusability. Thus far, the company’s record of success during similar first-flight reuse milestones remains flawless – the preservation of which will likely go far to salve the anxieties of more conservative customers like NASA and the US military.
SpaceX says that Starlink-15’s November 23rd backup date may not hold per the threat of bad weather at Falcon 9 B1049’s Atlantic Ocean landing zone several hundred miles downrange. Stay tuned for updates as the company tracks towards what could be its first four-launch month ever.
SpaceX has static fired a record-breaking Falcon 9 booster and says it’s ready to launch its 14th Starlink mission this year just a day and a half after sailing past the company’s previous annual launch record.
Set in 2018, SpaceX’s previous annual launch record stood at 21 missions – 20 Falcon 9s and one Falcon Heavy. Now, a little over halfway through November, SpaceX has easily bested itself, launching for the 22nd time to deliver oceanographic satellite Sentinel 6A to a polar orbit on November 21st.
Back on the East Coast, SpaceX fired up six-flight Falcon 9 booster B1049 just five hours after Sentinel 6A’s successful launch, setting the rocket up for its seventh flight – a first for SpaceX and reusable rocketry – in support of Starlink v1.0 Flight 15 (Starlink-15).
Following an apparent November 20th static fire abort and a brief 24-hour delay, B1049 is now scheduled to lift off no earlier than 9:56 pm EST (02:56 UTC), November 22nd with some 16 metric tons (~35,000 lb) of Starlink communications satellites in tow. Designed to ultimately blanket the Earth in affordable high-quality broadband internet, SpaceX has already begun to roll out a public beta test to what looks like one or several thousand users across the northern US and southern Canada.
Speaking on a November 21st Reddit Ask Me Anything (AMA) thread, one of the SpaceX Starlink engineers participating revealed that the company is targeting a “wider beta” rollout as early as late-January 2021. Despite having some 820 functioning Starlink satellites in orbit, approximately a third were recently launched and are still raising their orbits or waiting in phasing orbits to properly orient themselves and maximize Starlink internet coverage.
While it’s effectively impossible to predict which orbital ‘plane’ a given batch of Starlink satellites is targeting, it’s likely that the ~300 spacecraft still making their way to operational orbits will complete their journeys within the next 60 days. In general, it takes roughly 2-3 months from any given Starlink launch for all ~60 satellites to reach their operational 550 km (~340 mi) orbits, a process usually performed in batches of 22 – each essentially representing one evenly-space ring of internet coverage a few hundred miles wide.
Despite SpaceX tracking towards a truly record-breaking year of ~25+ launches, CEO Elon Musk revealed that the company is pushing to achieve as many as 48 launches in 2021, more than half of which would likely be Starlink missions.

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.
