Update: Around 9am CDT (UTC-5), SpaceX successfully fired up Starship serial number 11’s (SN11) three Raptor engines, completing the static fire test on the first try of the day and just two hours into in Monday’s eight-hour window.

As far as three-engine Starship static fires go, SN11’s Monday test was about as smooth and clean as they come, boding extremely well for a launch attempt as early as either Tuesday or Wednesday, according to Temporary Flight Restrictions (TFRs) filed with the FAA. With flight termination system (FTS) explosive charges already installed and an FAA license in hand, all that stands between Starship SN11 and flight is a deeper static fire review and the cooperation of local weather conditions. Stay tuned for updates!

A group of NASA astronauts appear to have taken an agency-sanctioned trip down to SpaceX’s Boca Chica Starship facilities, including a visit with a prototype scheduled to fire up and launch as early as this week.

Seemingly in lockstep with the accelerating pace of Starship production and testing, the frequency of NASA astronaut visits to SpaceX’s South Texas facilities has also seen an uptick over the last six or so months.

Back in 2019, SpaceX built Starhopper, performed numerous tests with early Raptor engine prototypes, and performed two untethered hops. With that success in hand, SpaceX turned its focus to Starship Mk1 and suffered an almost immediate failure during pressure testing, encouraging a series of rapid manufacturing upgrades largely completed in just a few months’ time.

In 2020, SpaceX pushed those new facilities to the limits while continuing major expansions. In 12 months, SpaceX built and tested five small ‘test tanks’ and six full Starship tank sections, performed almost a dozen Raptor static fires with that hardware, hopped two of those tanks (SN5 & SN6) to 150m, fully integrated the first full-height Starship (SN8), and nearly landed that vehicle after an otherwise flawless 12.5 km (7.8 mi) launch and descent.

Back in 2019, NASA inked its first monetary Starship contract with SpaceX, awarding $3M to prototype a coupling mechanism Starships will need to dock and refuel in space. In April 2020, NASA revealed that SpaceX – with its Starship launch vehicle – was one of three finalists selected to compete for a Human Landing System (HLS) Moon lander contract, providing the company $135M of the full $970M award to begin preliminary design and certification work.

Around five months later, a group of NASA astronauts made their first public visit to SpaceX’s Starship development hub in South Texas, overflying the factory and launch pad in training jets on a routine sortie out of Houston and Johnson Space Center. Days later, SpaceX won a $53M NASA “Tipping Point” contract to demonstrate large-scale cryogenic propellant transfer with a Starship prototype.

Ultimately, excluding rock-solid commercial crew and cargo partnerships, NASA’s relationship with SpaceX and the company’s Starship appears to be growing stronger every day. While it’s hard to say just how indicative of that growth the visible attention of NASA’s astronaut corps is, it’s worth taking note of what those same astronauts aren’t (publicly) overflying, visiting, and touring – namely factories, R&D facilities, or prototype hardware of HLS competitors Dynetics and Blue Origin.

Delayed by about a week, SpaceX is currently preparing to fire up its fourth full-size Starship prototype – SN11 – for the first time as early as Monday, March 22nd, 19 days after Starship SN10 briefly landed in one piece. SpaceX has filed temporary flight restrictions (TFRs) with the FAA for SN11’s 10 km (6.2 mi) launch debut from Tuesday through Friday, leaving plenty of opportunities for a launch this week if the rocket can successfully test its three Raptor engines by Wednesday.

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:

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.

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 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 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.
