SpaceX has a California launch date for the first time in 16 months
Just over a week after a Falcon 9 booster was spotted heading west, NASA has confirmed the date for SpaceX’s first California launch in more than 16 months.
Spotted in Texas on August 20th, Arizona on August 23rd, and at the entrance to Vandenberg Air Force Base (VAFB) on August 24th, the SpaceX rocket is almost certainly Falcon 9 booster B1063 or B1064. Regardless, it – alongside an expendable upper stage and (likely also expendable) payload fairing – will be flying for the first time on a fairly unique mission cosponsored by NASA.
Known as Sentinel-6A or Sentinel-6 Michael Freilich, after the late scientist and NASA director responsible for bringing several major Earth science missions to fruition, the 1500 kg (3300 lb) Airbus-built satellite is designed to measure ocean height and analyze the Earth’s atmosphere almost anywhere on Earth.
As previously discussed on Teslarati, the SpaceX booster spotted heading west late last month was almost certainly meant for Sentinel-6A.
NASA awarded SpaceX the $97 million launch contract in 2017, all but guaranteeing that Sentinel 6A will fly on a brand new Falcon 9 booster. The fact that the booster spotted in transport over the last week was never seen East of Texas strongly implies that it’s a new Falcon 9 SpaceX tested in McGregor before shipping back to California, in which case Sentinel 6A is almost certainly SpaceX’s next VAFB launch.
In the likely event that the booster that arrived at VAFB on August 24th is unflown, it’s probably Falcon 9 B1063. Germany’s SARah-1 radar imaging satellite is possibly the only other West Coast launch on SpaceX’s manifest that could warrant sending a new booster to California, but recent signs point towards that ~2200 kg (4850 lb) spacecraft launching in Q1 2021 (a delay from Q4 2020) as part of a dedicated SpaceX rideshare mission.
Less likely, SARah-1 could have been manifested on SpaceX’s first dedicated rideshare mission, scheduled to launch in December 2020. Either way, as fairly complex and expensive one-off science spacecraft, both SARah-1 and Sentinel 6A are liable to slip right from their current launch targets, meaning that Falcon 9 B1063 will likely spend at least 2-3 months in storage between now and the start of its first launch flow.

Now, just three days after SpaceX successfully completed the first East Coast polar launch in half a century, NASA has already unexpectedly revealed that SpaceX’s first dedicated rideshare mission – mentioned above and now deemed Transporter-1 – is still on track to launch in December 2020. However, SpaceX has moved the launch from California to Florida, killing the possibility that the new booster now at SpaceX’s Vandenberg launch facilities was meant for SARah-1.
The very next day, NASA’s Launch Services Program (LSP) office revealed that Sentinel-6A is officially targeting an 11:45am PDT (UTC-7), November 10th, 2020 launch on Falcon 9. Aside from giving SpaceX its first firm Vandenberg Air Force Base (VAFB) launch date since June 2019, the NASA update also revealed that the mission hasn’t slipped a single day after more than two months of reviews.
Due to the fact both of SpaceX’s operational drone ships are currently stationed in Florida, Sentinel-6A will include a guaranteed Falcon 9 booster landing back at Landing Zone-4, situated just a thousand feet or so away from the SLC-4E launch pad.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

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.
