SpaceX will attempt Falcon 9 upper stage landings in 2018, says Shotwell

Published

SpaceX also hopes to create an Internet constellation around Mars

In a candid and light-hearted presentation given at the Massachusetts Institute of Technology, SpaceX President Gwynne Shotwell revealed a considerable amount of exciting information about the space launch company’s future prospects and near-term goals.

Fascinatingly, Shotwell confirmed that SpaceX is currently attempting to procure nuclear materials in order to conduct research and development of nuclear propulsion for spacecraft. Nuclear-powered methods of propulsion have the potential to drastically increase the efficiency of spacecraft once in orbit, with the primary benefit being faster travel times around the Solar System. Faster transit times for manned spacecraft would translate into fewer consumables needed for those journeys, increasing the amount of other supplies that could be brought in a single trip. Beyond the orbit of Mars, other destinations humans might like to visit will require non-chemical propulsion, with more traditional rocketry leading to one-way voyages measured in years.

Equally exciting, she stated that SpaceX plans to attempt the first soft landing of Falcon 9’s upper stage before the end of 2018. Second stage recovery efforts would proceed much like Falcon 9’s first stage recovery did, beginning with attempts to land softly in the ocean and later bring in a droneship to attempt legitimate recoveries of the vehicle. While SpaceX’s now highly successful program of first stage recovery has taken the first steps to appreciably lower the cost of access to orbit, as much as 30% or more of the cost of every Falcon 9 launch can be found in the second stage and its many components, all of which are currently discarded every launch. Second stage recovery and reuse is nevertheless absolutely crucial to SpaceX’s and Elon Musk’s goal of reducing launch costs by anywhere from a factor of 10 to 100.

Still, the payload fairing – a major component of the Falcon 9 – costs approximately $5 million on its own, nearly 10% of the cost of a $62 million expendable launch. SpaceX has been making concerted progress towards fairing recovery and reuse, and Musk has said that he expects SpaceX to accomplish the first successful fairing recoveries before the end of 2017. The second stage is thus the obvious next step if the goal is to create a fully-reusable Falcon 9. SpaceX, however, seem to be prioritizing a different path.

Shotwell clarified that SpaceX would not attempt to reuse Falcon 9’s upper stage, even if recovery efforts succeed. This suggests that SpaceX is planning to focus the majority of its research and development staff and capital on their considerably larger “BFR (Big Falcon Rocket) planetary colonizer” vehicle, which will be unveiled for the first time later today. Hence, Shotwell’s comment lends confidence to the belief that Falcon 9 will never become fully reusable, which makes sense. The decision to focus energy on a new launch vehicle is arguably a more efficient and productive task than modifying Falcon 9 even more drastically. The development of an entirely new rocket offers SpaceX the freedom to design for complete reusability from the start, whereas Falcon 9’s path to partial reusability has been inevitably circuitous.

Finally, Shotwell briefly discussed SpaceX’s desire to create a vast constellation of Internet satellites around Earth, stating that their goal was “make scads of cash, spend it going to Mars, [and] give Mars broadband too!”. This aligns with speculation and leaked financial documents. Just yesterday, the Federal Communications Commission (FCC) held an Open Commission meeting where they voted to hand off certain aspects of regulatory approval to the International Telecommunications Union, which is a relatively positive development for SpaceX’s satellite constellation.

Regardless, Musk is bound to reveal some even more thrilling details about SpaceX in his presentation at the 2017 International Astronautical Congress. Currently scheduled for 4 a.m UTC on September 29, or 9:30 p.m. PDT on September 28, and an official SpaceX.com livestream is expected to be provided for those who were unable to make the long journey to Adelaide, Australia.

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.
