SpaceX says Starship Mk1 will test ‘skydiver’ landing before the end of 2019
A senior SpaceX director says that the Starship Mk1 prototype could lift off for the first time before the end of 2019, a flight debut SpaceX hopes will successfully demonstrate the next-generation spacecraft’s exotic ‘skydiver’ landing method.
SpaceX is in the late stages of building the first full-scale Starship prototypes, known as Mk1 (situated in Boca Chica, Texas) and Mk2 (Cocoa, Florida). The Texas-based Mk1 prototype is by far the furthest along and featured prominently at CEO Elon Musk’s Starship update presentation on September 28th, having been stacked to its final height of ~50m (165 ft) for the first time just days prior.
It’s clear now that more than a little showmanship was involved in the work that lead up to Starship Mk1’s unveiling. Within a week or two of the event, SpaceX technicians had separated Starship’s nose and tail sections, removed all three Raptor engines, and uninstalled the ship’s wings and canards, among other things.
Aside from the nose and tail section demate and removal of flaps, canards, and Raptors, the aero covers that were briefly attached to Starship’s exterior (raceways, canards, flaps, legs) were also removed. One raceway cover may or may not have been a casualty of high winds but all of the above hardware was carefully stored on the ground surrounding Starship Mk1 and is clearly meant to be installed more permanently in the coming weeks.
Nevertheless, Starship Mk1 obviously has a decent ways to go before it can be seriously considered flight-ready. On a positive note, aside from several days spent undressing Starship, SpaceX’s South Texas team (and others traveling from Florida and California) have been working 24/7 in the weeks since Musk’s presentation.
The last two weeks of Starship Mk1 activity have centered around installing the numerous crucial bits and pieces the rocket will need to function. This has included thousands of feet of power cables, avionics wiring, and propellant feed and transfer pipes; industrial-scale power controllers and flight computers, and much more.
The sheer quantity and range of sizes of piping being installed on Starship Mk1 all but confirms that the rocket will be a high-fidelity prototype capable of testing a wide range of capabilities related to autogenous pressurization and Raptor engine ignition. The mirrored presence of three sets of smaller pipes on the vehicle’s raceway (essentially a utility corridor) is a strong sign that Raptor and Starship’s smaller header tanks and COPVs (located in Mk1’s nose section) are closely related.
Some of the excess hot gas produced by Raptor may be tapped to supply COPVs that can then be used to reignite the engines in-flight. More likely, the small pipes are more of a one-way feed line from Starship’s header tanks to its Raptor engines and – as Musk has indicated – the cryogenic liquid propellant in those header tanks will be gasified with electric heaters or gas generators.
Starship gymnastics
Given all of the above, close followers were already readily aware of the fact that Starship Mk1 needed some significant work done before it would be ready for flight. On October 22nd, SpaceX Senior Director Gary Henry confirmed these suspicions, indicating that Starship Mk1’s 20 km (12 mi) flight test debut was now scheduled no earlier than two months from now (December 2019).
According to CEO Elon Musk and other SpaceX engineers, that 20 km flight debut is designed to prove that Starship’s radical new approach to flight and landing is viable. Musk has repeatedly described that Starship will in no way be an actual space plane and has stated that its ‘wings’ and ‘canards’ are not intended to be airfoils or wings. Instead, Starship will reenter Earth’s atmosphere, slow its horizontal velocity to near-zero, and proceed to free-fall straight down, using its fore and aft flaps to control its trajectory in the same way that skydivers use their body and limbs.
This bizarre approach will be capped off with an aggressive landing maneuver in which Starship will ignite its engines, wildly thrust-vector and swerve to cancel out the horizontal velocity imparted by that sideways ignition, and land vertically on Earth (or Mars). In theory, this strategy will radically reduce the amount of fuel Starship needs to land in atmospheres, but it’s far removed from anything SpaceX has attempted with Falcon 9 and Starship Mk1’s first flight will hopefully prove it to be a viable solution.

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.

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:Â
“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.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.Â
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.Â
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.Â
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.Â
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
