SpaceX lifts soggy Falcon 9 Block 5 booster ashore after accidental splashdown

Ignore Falcon 9 B1050's battered interstage and it would be nearly impossible to tell - at a glance - that anything went wrong during the rocket's recovery.

Independent group USLaunchReport has published a video capturing the entirety of SpaceX’s ad hoc East Coast Falcon 9 recovery operations, in which forlorn booster B1050 had to be carefully extracted out of the ocean after an unintentional soft-landing in the Atlantic following its successful Dec. 5 launch debut.

72 hours after B1050’s water landing and some painstaking preparation, the booster was towed to SpaceX’s dock space in Port Canaveral, where it spent just a brief few hours floating adjacent to drone ship Of Course I Still Love You and the rest of the company’s Florida fleet. Considerably less than twelve hours after arriving, technicians had already managed to lift the rocket out of the ocean and onto dry land, where another week or so was spent preparing Falcon 9 for transport.

Given the extent of the damage to the Block 5 booster’s interstage and the basic fact that SpaceX recovery technicians and engineers had never attempted anything quite like it before, it was fairly impressive that they took barely six hours to lift the booster out of the water, particularly considering that the rocket appeared to be filled with hundreds or even thousands of gallons of water. No visible damage was caused, although there was clearly some cause for extensive discussion and preparation per an unusually large and lengthy huddle of more than 30 employees prior to the beginning of the lift.

Once on land, B1050 had an unusual sling placed exactly where the Falcon 9 booster’s liquid oxygen (LOx) and kerosene (RP-1) propellant tanks were welded together, apparently a location that is particularly sensitive to off-nominal X-axis stress. To give context, imagine bending a cardboard tube or straw in half instead of trying to push its ends together – Falcon 9’s structure is quite similar in concept. Built primarily 5mm-thick sheets of lithium-aluminum alloy, Falcon 9’s propellant tanks are extremely thin and light while also being aggressively optimized for vertical (up and down) loading, i.e. the forces experienced while accelerating (and eventually decelerating) through the atmosphere during launch and landing.

As a result, SpaceX almost always pressurizes the first stage propellant tanks of Falcon 9 with nitrogen whenever boosters are horizontal without physical support at their bendy centers. In the case of B1050, SpaceX almost certainly concluded that using its waterlogged umbilical ports to inject nitrogen into its tanks was too much of a risk without knowing the precise condition of the piping and the tanks themselves, opting instead to go with a simple sling to prevent damage from unintended bending. Thankfully, B1050 appears to have made it through its dry land ordeal even better than the time it spent in the Atlantic, suffering no visible damage whatsoever.

Somewhere between December 14 and 15, the booster was at long last lifted onto SpaceX’s primary East Coast booster transporter and carefully drove the rocket to one of its 2-3 Cape Canaveral Air Force Station (CCAFS) refurbishment and storage hangars, avoiding detection by all but a few passersby. This could full well be the last we see (and even hear) of poor old Falcon 9 B1050, but there is still a decent chance that SpaceX hopes the entire rocket or major components can be easily salvaged.

Given the extreme care taken during the booster’s lift onto land and the week it spent having legs and grid fins removed, it can be definitively concluded that an effort will be made to save the entire vehicle (sans interstage). If it has managed to make it through the past two weeks largely unscathed, it may well become the first Falcon 9 to conduct a dedicated launch of multiple Starlink satellites sometime in the second half of 2019, at least according to CEO Elon Musk’s vague suggestion that it could fly on an “internal SpaceX mission”.

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:

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 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.
