Following in the footsteps of the late Mk1 vehicle, SpaceX’s latest Starship prototype has been outfitted with several Tesla battery packs and motors over the last few weeks.

CEO Elon Musk has confirmed in the past that SpaceX intends to try to use Tesla batteries to power Starship rockets and Tesla motors to drive the ships’ large aerodynamic control surfaces. By all appearances, a Tesla Model S motor’s appearance on the exterior of a Starship prototype recently moved to the launch pad is a first for SpaceX. However, in 2019, SpaceX at one point planned to use and even installed battery packs on Starship Mk1 components before the ship was prematurely destroyed during testing. The nosecone those battery packs were installed in still sits in the middle of SpaceX’s growing Boca Chica rocket factory.

For Starship SN3, the purpose of its ~200 kWh of battery power is rather self-explanatory. The purpose of the Tesla Model S motor recently installed on its side is much less clear.

SpaceX is in the midst of preparing Starship SN3 for its first tests after assembling the rocket from next to nothing in less than a month. SpaceX transported the building-sized prototype a mile down the road to its Boca Chica launch site on March 29th, where dozens of workers have been poring over it day and night ever since. SpaceX originally wanted to attempt the ship’s first two tests yesterday, April 1st, but the scheduled times have come and gone while work continues. Several backup windows are ready on April 2nd, beginning shortly before this article went live (1am CDT, 06:00 UTC).

Regardless, with any rocket prototype, test schedules can be extremely fluid and are always liable to change. While SpaceX relies heavily on agile development strategies, beginning with a minimum viable product and iterating to something approaching feature-complete, there is some value in not turning the “move fast and break stuff” dial to 100%. In the case of Starship, the equivalent of tens to hundreds of thousands of work hours and several million dollars of hardware go into each prototype – incredibly cheap on the scale of aerospace development norms but still a significant chunk of change and effort. A few days or weeks of delays are an annoyance that can be suffered if it better guarantees a successful test, versus the alternative of potentially rushing and cutting corners.

SpaceX is now up to roughly five days of delays while preparing Starship SN3 for testing. Originally scheduled as early as April 1st, SpaceX has moved a planned Raptor engine static fire test to no earlier than (NET) April 6th, to be followed no fewer than several days later by a 150m (500 ft) hop test. Of course, before it can safely attempt its first static fire (or hop), SpaceX needs to verify that Starship SN3 – finished just days ago – is up to the task.

Enter Tesla hardware. During ground testing, Starship will likely be continuously connected to ground power sources. It’s also possible that SpaceX has chosen to use its Tesla battery packs as the main power source to insulate it from local outages. Either way, if or when Starship SN3 makes it to flight tests, the battery packs would power the ship’s onboard avionics, landing legs, and any other necessary equipment. That latter category may be where Starship’s apparent Model S motor comes in.

A member of the NASASpaceflight forum was first to realize that this appendage was almost certainly a Tesla Model S motor assembly. (NASASpaceflight – bocachicagal)

While it could simply be an early implementation test of the Tesla motors SpaceX wants to use to actuate Starship flaps and fins, there are no signs that SN3 will be outfitted with updated flaps and aerodynamic control surfaces more generally. For low-velocity testing, they’re simply unnecessary. Instead, it’s more likely that this Tesla motor is somehow involved in Starship’s autogenous pressurization system, a method of pressurizing tanks with the liquids they contain. Autogenous pressurization relies on a small portion of propellant (liquid oxygen and methane for Starship) being siphoned off and heated until it turns to gas. That oxygen or methane gas is then fed back into the tank it came from, keeping it at the pressure needed to feed Starship’s Raptor engines.

Autogenous pressurization is significantly more complex than the far more common use of helium or nitrogen pressurization systems. An electric pump could potentially be useful at several points throughout the process. Pump mystery aside, tune in to LabPadre’s 24/7 livestream below to follow along as SpaceX prepares to put Starship SN3 to the test for the first time.

Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says

Tesla Full Self-Driving is set to get an awesome new feature in the near future, CEO Elon Musk confirmed on X.

Full Self-Driving is the company’s semi-autonomous driving program, which is among the best available to the general public. It still relies on the driver to ultimately remain in control and pay attention, but it truly does make traveling less stressful and easier.

However, Tesla still continuously refines the software through Over-the-Air updates, which are meant to resolve shortcomings in the performance of the FSD suite. Generally, Tesla does a great job of this, but some updates are definitely regressions, at least with some of the features.

Tesla and Musk are always trying to improve the suite’s performance by fixing features that are presently available, but they also try to add new things that would be beneficial to owners. One of those things, which is coming soon, is giving the driver the ability to prompt FSD with voice demands.

For example, asking the car to park close to the front door of your destination, or further away in an empty portion of the parking lot, would be an extremely beneficial feature. Adjusting navigation is possible through Grok integration, but it is not always effective.

Musk confirmed that voice prompts for FSD would be possible:

Tesla Full Self-Driving is a really great thing, but it definitely has its shortcomings. Navigation is among the biggest complaints that owners have, and it is easily my biggest frustration with using it. Some of the routes it chooses to take are truly mind-boggling.

Another thing it has had issues with is being situated in the correct lane at confusing intersections or even managing to properly navigate through local traffic signs. For example, in Pennsylvania, there are a lot of stop signs with “Except Right Turn” signs directly under.

This gives those turning right at a stop sign the opportunity to travel through it. FSD has had issues with this on several occasions.

Parking preferences would be highly beneficial and something that could be resolved with this voice prompt program. Grocery stores are full of carts not taken back by customers, and many people choose to park far away. Advising FSD of this preference would be a great advantage to owners.

Elon Musk clarifies Tesla Cybertruck ’10 day’ comment, fans respond

Some are arguing that the decision to confirm a price hike in ten days is sort of counterproductive, especially considering it is based on demand. Giving consumers a timeline of just ten days to make a big purchase like a pickup truck for $60,000, and basically stating the price will go up, will only push people to make a reservation.

Elon Musk has clarified what he meant by his comment on X yesterday that seemed to indicate that Tesla would either do away with the new All-Wheel-Drive configuration of the Cybertruck or adjust the price.

The response was cryptic as nobody truly knew what Musk’s plans were for the newest Tesla Cybertruck trim level. We now have that answer, and fans of the company are responding in a polarizing fashion.

On Thursday night, Tesla launched the Cybertruck All-Wheel-Drive, priced competitively at $59,990. It was a vast improvement from the Rear-Wheel-Drive configuration Tesla launched last year at a similar price point, which was eventually cancelled just a few months later due to low demand.

However, Musk said early on Friday, “just for 10 days,” the truck would either be available or priced at $59,990. We can now confirm Tesla will adjust the price based on more recent comments from the CEO.

Musk said the price will fluctuate, but it “depends on how much demand we see at this price level.”

Some are defending the decision, stating that it is simply logical to see how the Cybertruck sells at this price and adjust accordingly.

Others, not so much.

Some are arguing that the decision to confirm a price hike in ten days is sort of counterproductive, especially considering it is based on demand. Giving consumers a timeline of just ten days to make a big purchase like a pickup truck for $60,000, and basically stating the price will go up, will only push people to make a reservation.

Demand will look strong because people want to lock in this price. The price will inevitably go up, and demand for the trim will likely fall a bit because of the increased cost.

Many are arguing Musk should have kept this detail internal, but transparency is a good policy to have. It is a polarizing move to confirm a price increase in just a week-and-a-half, but the community is obviously split on how to feel.

Tesla Cybertruck’s newest trim will undergo massive change in ten days, Musk says

It appears as if the new All-Wheel-Drive trim of Cybertruck won’t be around for too long, however. Elon Musk revealed this morning that it will be around “only for the next 10 days.”

Tesla’s new Cybertruck trim has already gotten the axe from CEO Elon Musk, who said the All-Wheel-Drive configuration of the all-electric pickup will only be available “for the next ten days.”

Musk could mean the price, which is $59,990, or the availability of the trim altogether.

Last night, Tesla launched the All-Wheel-Drive configuration of the Cybertruck, a pickup that comes in at less than $60,000 and features a competitive range and features that are not far off from the offerings of the premium trim.

Tesla launches new Cybertruck trim with more features than ever for a low price

It was a nice surprise from Tesla, considering that last year, it offered a Rear-Wheel-Drive trim of the Cybertruck that only lasted a few months. It had extremely underwhelming demand because it was only $10,000 cheaper than the next trim level up, and it was missing a significant number of premium features.

Simply put, it was not worth the money. Tesla killed the RWD Cybertruck just a few months after offering it.

With the news that Tesla was offering this All-Wheel-Drive configuration of the Cybertruck, many fans and consumers were encouraged. The Cybertruck has been an underwhelming seller, and this seemed to be a lot of truck for the price when looking at its features:

  • Dual Motor AWD w/ est. 325 mi of range
  • Powered tonneau cover
  • Bed outlets (2x 120V + 1x 240V) & Powershare capability
  • Coil springs w/ adaptive damping
  • Heated first-row seats w/ textile material that is easy to clean
  • Steer-by-wire & Four Wheel Steering
  • 6’ x 4’ composite bed
  • Towing capacity of up to 7,500 lbs
  • Powered frunk

It appears as if this trim of Cybertruck won’t be around for too long, however. Musk revealed this morning that it will be around “only for the next 10 days.”

Musk could mean the price of the truck and not necessarily the ability to order it. However, most are taking it as a cancellation.

If it is, in fact, a short-term availability decision, it is baffling, especially as Tesla fans and analysts claim that metrics like quarterly deliveries are no longer important. This seems like a way to boost sales short-term, and if so many people are encouraged about this offering, why would it be kept around for such a short period of time?

Some are even considering the potential that Tesla axes the Cybertruck program as a whole. Although Musk said during the recent Q4 Earnings Call that Cybertruck would still be produced, the end of the Model S and Model X programs indicates Tesla might be prepared to do away with any low-volume vehicles that do not contribute to the company’s future visions of autonomy.

The decision to axe the car just ten days after making it available seems like a true head-scratcher.
