SpaceX continues water landing test in latest Space Station resupply mission

Published

on

SpaceX has completed their second launch in less than four days, and the company’s 14th Cargo Dragon mission has successfully made it to a safe parking orbit where it will make its way to the International Space Station over the next two days.

Carrying nearly 5,800 pounds of perishables, experiments, and scientific equipment to be bolted to the outside of the ISS, this particular Cargo Dragon flew once before in 2016, while the booster that lifted it above Earth’s thin atmosphere was tasked with launching CRS-12 in August 2017. According to Jessica Jensen, SpaceX’s Director of Dragon Mission Management, this particularly Dragon capsule was the first to fly with upgraded water sealing, meaning that it was considerably easier (and thus cheaper) for SpaceX to refurbish and refly. The only items that had to be replaced this time around were the heatshield, trunk, and parachutes, and this experience will undoubtedly translate into Dragon 2 (Cargo Dragon), likely ensuring exceptional reuse characteristics for that the company’s next-gen capsule.

Sadly, CRS-14’s doubly flight-proven launch also marked yet another expended booster – B1039 happened to be the first Block 4 version of Falcon 9’s stage to fly a mission. Jensen described that SpaceX – accustomed to making these decisions on a case-by-case basis – had chosen to expend this particular booster after concluding that the benefits of testing extreme booster trajectories and recovery profiles outweighed the difficulty (and cost) of refurbishing a Block 4 booster for a third launch. In this case, B1039 would have been the best option if SpaceX had any desire to fly a booster more than twice before the introduction of the purpose-driven, next-generation Block 5 reusability upgrade – Block 4 was clearly not built to fly more than twice without an uneconomical amount of refurbishment.

While no specific details were given and live coverage shown of the soft-landing, it’s presumed that B1039 continued in the footsteps of water landings that followed GovSat-1 and Hispasat 30W-6 in January 2018 and March 2018. These uniquely aggressive landing attempts are all believed to have ignited three Merlin 1D engines rather than the single engine typically ignited for landing burns, providing a more efficient use of propellant reserves at the cost of extreme acceleration (G) forces and far slimmer margins of error. The ultimate promise of these tests, if successful, is to allow SpaceX the option of recovering boosters during missions with heavier payloads and higher orbits.

The imminent NET April 24 inaugural launch of SpaceX’s rapid reuse Falcon 9 “Block 5” will mark the beginning of a new era of rocketry for SpaceX, where expendable missions are likely to become a rarity. Expending a single Block 5 booster could fairly be perceived as throwing away the potential revenue and income from anywhere from 5-100 future re-flights. As such, SpaceX has every reason to expend non-Block 5 boosters with the hope of ensuring that fewer new-generation rockets end up expended after launch.

Intriguingly, Jensen also noted in a prelaunch briefing that SpaceX’s Cargo Dragons are certified for as many as three orbital reuses – a possibility as SpaceX steps towards completing all 20 of its contracted CRS-1 missions, the final five of which are scheduled to resupply the ISS between now and early 2020. After the final CRS-1 launch, NASA has already awarded SpaceX and Orbital ATK contracts for CRS-2, a second Commercial Resupply Services contract that will begin in 2020 and fly on OATK’s upgraded Cygnus and SpaceX Dragon 2, potentially repurposing recovered Crew capsules in the case of SpaceX.

Up next on the SpaceX calendar are a number of conferences and presentations over the next two or three weeks, followed by SpaceX NASA TESS mission on April 16 and the debut of Falcon 9 Block 5 for the launch of Bangabandhu-1, April 24. SES-12 may be launched sometime in early May or late April, and the next West coast launch of Iridium-6/GRACE-FO is expected to occur NET May 10.

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

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.
