SpaceX’s West Coast drone ship begins Panama Canal transit on journey to Florida (or Texas)
After traveling more than 3500 miles (5600 km), SpaceX autonomous spaceport drone ship (ASDS) Just Read The Instructions (JRTI) began its eastbound transit of the Panama Canal on August 18th, placing the vessel roughly two-thirds of the way to its unknown destination.
As previously discussed on Teslarati, JRTI’s move came as a bit of a surprise and it’s still anyone’s bet if the SpaceX recovery vessel heads for Texas or Florida immediately after exiting the Panama Canal. Nevertheless, JRTI’s presence at either (or, more likely, both) possible destinations arguably centers around the imminent demands of a planned ramp of SpaceX’s Starlink satellite constellation launch cadence, as well as an equally imminent need for recovery assets to support the first suborbital Starship test flights.
On July 31st, JRTI departed Port of Los Angeles – its home for the last four years – under tow behind tugboat Alice C. The duo arrived at the Canal on August 15th and, after a several-day wait in a large passage queue, the drone ship and its paired tugboat are finally on their way through the canal, although traffic still remains high and another day (or several) of waiting is likely in order.
After successfully making it through the first half of the transit, JRTI and Alice C are currently waiting in line while westbound traffic is routed through. That wait will likely last hours, not days, (hopefully) allowing JRTI to exit the canal on Tuesday or Wednesday, leaving drone ship free to head towards its final destination.
JRTI has two possible destinations: Port of Brownsville, Texas or Port Canaveral, Florida. Both options are roughly 1800 mi (3000 km) from the Panama Canal’s western mouth and, extrapolating from the first major leg of the journey, should take Alice C around 8 days to tow JRTI across the finish line. Barring mishaps, the drone ship should thus be able to arrive at its new home sometime in the final week of August – roughly August 27th to the 31st.
To the East, to the Gulf
As previously discussed on Teslarati, there are good cases to make for both potential drone ship destinations. On the East Coast, SpaceX’s plans to ramp up its internal Starlink launch cadence could require multiple drone ship to prevent those ambitions from seriously impacting the company’s commercial launch manifest. The readiness of one or two of the payloads is uncertain, but SpaceX has anywhere from seven to nine Falcon 9 launches scheduled in Q4 2019, requiring a cadence significantly higher than SpaceX’s activity in the first half of 2019.
At the same time, extrapolating from SpaceX’s H1 2019 cadence (1.33 launches per month), more than doubling that average cadence to 3 launches per month in the final quarter seems ambitious, at a minimum. SpaceX has achieved six-launch quarters several times in the last few years, likely a reasonable expectation for Q4 2019. In short, this is all to say that SpaceX has made do with one drone ship in the past while hitting similar launch cadences, meaning that the need for JRTI at Port Canaveral is probably not urgent.
On the Gulf Coast, SpaceX has established a Starship development facility in Boca Chica, Texas, just a handful of miles north of the southernmost tip of Texas. A full-scale, low-fidelity prototype known as Starhopper completed its first test flight on July 25th and is likely just days away from a second test flight. Meanwhile, SpaceX Boca Chica is simultaneously assembling what CEO Elon Musk has described as the “Mk1” orbital Starship prototype and is making spectacularly rapid progress.
Musk recently tweeted that SpaceX’s Mk1 Starship and a second parallel build – Starship Mk2 – could be ready for their first (suborbital) flights as early as late-September or October, followed by one of the spacecraft’s first orbital launch attempt an incredibly ambitious “2-3 months after” the first test flight. Per additional statements from Musk in 2018 and 2019, SpaceX plans to subject either or both of its Mk1 and Mk1 Starships to a high-altitude, high-velocity test program before proceeding to orbital launch attempts.
Said extreme testing could easily involve Starship traveling on high suborbital trajectories dozens or even hundreds of miles above Earth’s surface, potentially demanding an ocean-going landing platform far downrange. Given that Starship is in its very early stages of integrated development, any downrange assets (i.e. JRTI) needed for test flights will need to be very flexible, as Starship launch attempts could easily slip days or weeks with little to no notice.
Best of both worlds
Although pitting options against each other is entertaining and has its uses, the fact remains that once drone ship JRTI has passed through the Panama Canal, traveling from, say, Florida to Texas or vice versa is far less arduous a journey than the trip from Port of LA. In other words, moving JRTI between Port of Brownsville and Port Canaveral every few months should be very little trouble, easily allowing the drone ship to service both Gulf and East Coast recovery needs.
Given that SpaceX’s next Falcon 9 launch is believed to be no earlier than late-October, it’s not even out of the question that JRTI will stop in Brownsville for one month or several before heading to Port Canaveral as SpaceX attempts to complete a very busy Q4 2019 launch manifest. Stay tuned…

Tesla already has a complete Robotaxi model, and it doesn’t depend on passenger count
That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.
Tesla already has the pieces in place for a full Robotaxi service that works regardless of passenger count, even if the backbone of the program is a small autonomous two-seater.
That scenario was discussed during the company’s Q4 and FY 2025 earnings call, when executives explained why the majority of Robotaxi rides will only involve one or two people.
Two-seat Cybercabs make perfect sense
During the Q&A portion of the call, Tesla Vice President of Vehicle Engineering Lars Moravy pointed out that more than 90% of vehicle miles traveled today involve two or fewer passengers. This, the executive noted, directly informed the design of the Cybercab.
“Autonomy and Cybercab are going to change the global market size and mix quite significantly. I think that’s quite obvious. General transportation is going to be better served by autonomy as it will be safer and cheaper. Over 90% of vehicle miles traveled are with two or fewer passengers now. This is why we designed Cybercab that way,” Moravy said.
Elon Musk expanded on the point, emphasizing that there is no fallback for Tesla’s bet on the Cybercab’s autonomous design. He reiterated that the autonomous two seater’s production is expected to start in April and noted that, over time, Tesla expects to produce far more Cybercabs than all of its other vehicles combined.
“Just to add to what Lars said there. The point that Lars made, which is that 90% of miles driven are with one or two passengers or one or two occupants, essentially, is a very important one… So this is clearly, there’s no fallback mechanism here. It’s like this car either drives itself or it does not drive… We would expect over time to make far more CyberCabs than all of our other vehicles combined. Given that 90% of distance driven or distance being distance traveled exactly, no longer driving, is one or two people,” Musk said.
Tesla’s robotaxi lineup is already here
The more interesting takeaway from the Q4 and FY 2025 earnings call is the fact that Tesla does not need the Cybercab to serve every possible passenger scenario, simply because the company already has a functional Robotaxi model that scales by vehicle type.
The Cybercab will handle the bulk of the Robotaxi network’s trips, but for groups that need three or four seats, the Model Y fills that role. For higher-end or larger-family use cases, the extended-wheelbase Model Y L could cover five or six occupants, provided that Elon Musk greenlights the vehicle for North America. And for even larger groups or commercial transport, Tesla has already unveiled the Robovan, which could seat over ten people.
Rather than forcing one vehicle to satisfy every use case, Tesla’s approach mirrors how transportation works today. Different vehicles will be used for different needs, while unifying everything under a single autonomous software and fleet platform.

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.
