During a recent NASA council meeting, SpaceX’s response to a Crew Dragon capsule’s April 20th explosion was repeatedly praised by the agency’s senior Commercial Crew Program (CCP) manager, her optimism clearly rekindled after several undeniably challenging months.

On October 29th and 30th, NASA held its second 2019 Advisory Council (NAC) meeting, comprised of a number of (more or less) independent advisors who convene to receive NASA updates and provide a sort of third-party opinion on the agency’s programs. Alongside NASA’s SLS rocket and Orion spacecraft, Commercial Crew continues to be a major priority for NASA and is equally prominent in NAC meetings, where program officials present updates.

On October 30th, CCP manager Kathy Lueders presented one such update on the progress being made by Commercial Crew providers Boeing and SpaceX, both of which are just weeks away from multiple crucial tests. Boeing is scheduled to perform a pad abort test of its Starliner spacecraft as early as November 4th, while SpaceX is targeting a static fire of a Crew Dragon capsule on November 6th. If that test fire is successful, the same capsule could be ready to support SpaceX’s In-Flight Abort (IFA) test in early-December, and Boeing’s Starliner could attempt its orbital launch debut (OFT) no earlier than (NET) December 17th.

For both SpaceX and Boeing, the results of their respective In-Flight Abort and Orbital Flight Test will determine just how soon NASA will certify each company to attempt their first commercial launches with astronauts aboard. If Boeing’s Pad Abort goes perfectly and Starliner’s NET December 17th OFT is also a total success, the company could be ready for its Crewed Flight Test (CFT) anywhere from 3-6+ months after (March-June 2020).

If SpaceX’s IFA test goes perfectly next month, Crew Dragon’s Demo-2 astronaut launch could occur as early as February or March 2020. In April 2019, SpaceX suffered a major setback when flight-proven Crew Dragon capsule C201 violently exploded milliseconds before a planned abort thruster static fire test, reducing the historic spacecraft to a field of debris. Before that failure, C201 had been assigned to perform the in-flight abort test, while capsule C205 was in the late stages of assembly for Demo-2.

Had that explosion never happened and the C201 IFA gone perfectly, Demo-2 could have potentially been ready for launch as early as August or September 2019. Instead, C201’s demise forced SpaceX to change capsule assignments, reassigning C205 to support Crew Dragon’s IFA, while C206 was moved to Demo-2. Nevertheless, as both SpaceX and NASA officials have noted, C201’s on-pad explosion has been viewed as a gift, for the most part, as the capsule failed in a largely controlled and highly-instrumented environment.

In fact, NASA manager Kathy Lueders complimented NASA’s involvement in the anomaly resolution process and repeatedly praised SpaceX’s response to Dragon’s explosion. Although the explosion was an undesirable result, SpaceX’s relentless prioritization flight hardware testing prevented a failure from occurring in flight. Performed alongside NASA, SpaceX’s subsequent investigations and experimentation have essentially brought to light a new design constraint, the knowledge of which many space agencies and companies will likely benefit from.

Most notably, however, Lueders detailed how impressed she was at the incredible speed with which SpaceX was able to respond to Crew Dragon’s catastrophic static fire anomaly.

“So the nice thing is that the SpaceX folks had a bunch of vehicles in flow. So even though we lost Demo-1 [capsule C201], … [SpaceX] was able to pull up what was going to be our Demo-2 vehicle, outfit it, make [necessary] changes [and upgrades] to the vehicle, and get it ready for [flight] with a six-month slip — a pretty phenomenal turnaround.

Kathy Lueders – NASA – 10/30/19

Crew Dragon C201 exploded on April 20th, 2019. Five months and seven days later, a new Crew Dragon capsule and trunk – having undergone significant modifications as a result of the C201 explosion investigation – were delivered to SpaceX’s Florida facilities for their new role, Dragon’s In-Flight Abort test. Meanwhile, despite the upset and general instability, Crew Dragon capsule C206 – previously assigned to the flight after Demo-2 – is in the late stages of assembly and integration and is expected to ship to Florida for preflight preparations in early-December.

Altogether, those turnaround times are almost unheard of for such complex systems. For example, Boeing’s Starliner service module – generally less complex than the crew capsule – suffered a serious anomaly during a June 2018 static fire test. As a result, Boeing had to fully replace the service module with new hardware and repeat the same test before it could proceed to Starliner’s Pad Abort, at the time expected a few weeks later (Q2 2018).

Like SpaceX, Boeing was forced to cannibalize future launch hardware to re-attempt its static fire test, which was ultimately completed some 11 months after the anomaly on May 24th, 2019. The Pad Abort previously expected in mid-2018 is now expected no earlier than November 4th, 2019, a delay of 12-16 months. In simpler terms, the six or so months that Crew Dragon C201’s explosion has delayed SpaceX’s In-Flight Abort test is an undeniably “phenomenal turnaround” relative to both NASA’s expectations and SpaceX’s peers.

A happy partnership

The day prior, famed ex-NASA engineer and Space Shuttle program manager Wayne Hale – now serving as NAC chair – brought up SpaceX in an entirely different context, deeming the company as a whole a “sterling example” of NASA’s ability to incubate and incentivize commercial spaceflight.

Indeed, SpaceX has radically reshaped almost every aspect of the global spaceflight industry in the ten years since NASA awarded the company its first major contract, proving that orbital-class commercial rockets can be built, landed, and reused – all for far less money than NASA or competitors believed was possible.

All things considered, NASA appears to be more content than ever with the results its fruitful SpaceX partnerships are producing, and a number of senior NASA officials seem to be increasingly willing to unbridle their enthusiasm as a result.

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 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.
