SpaceX Starship outfitted with Tesla battery packs and motors
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.
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.

SpaceX blocks unauthorized Starlink terminals used by Russian troops
Ukrainian officials confirmed that Starlink terminals believed to be used by Russian troops were disabled after coordination with SpaceX.
SpaceX has taken steps to block unauthorized use of its Starlink satellite internet network, a move Ukrainian officials stated is already disrupting Russian military communications.
Russian units lose a key communications tool
As per a report from The Guardian, Ukrainian defense officials have confirmed that Starlink terminals believed to be used by Russian troops were recently disabled after coordination with SpaceX. The move reportedly affected frontline communications and drone operations, especially in areas where traditional military radios are unreliable or easily jammed.
For months, Russian units had relied on large numbers of illicitly obtained Starlink terminals to stay connected along the front. The satellite internet service allowed faster coordination and more precise drone use for Russian forces.
Several Russian military bloggers close to frontline units have acknowledged the impact of the Starlink shutdown, with some describing sudden connectivity problems in the satellite internet service.
Russia lacks comparable replacement
Russia does not have a satellite internet system that matches Starlink’s speed, coverage, and ease of deployment. Alternatives such as fiber-optic lines, short-range wireless links, and digital radio systems take longer to install and work inadequately for fast-moving units.
Russia does operate limited satellite communications through state-linked providers, but those systems rely mainly on geostationary satellites, which are notably slower. Coverage is uneven, and data capacity is far lower than Starlink’s low-Earth-orbit network.
For now, Ukraine has stated that it has introduced a verification system that allows only approved Starlink terminals to connect. Devices believed to be linked to Russian forces are blocked from the network. That being said, Ukrainian officials have also claimed Russian units are trying to work around the restrictions by asking civilians to register Starlink terminals in their names.

Tesla Semi pricing revealed after company uncovers trim levels
This is a step up from the prices that were revealed back in 2017, but with inflation and other factors, it is no surprise Tesla could not come through on the numbers it planned to offer nine years ago. When the Semi was unveiled in November 2017, Tesla had three pricing levels:
Tesla Semi pricing appears to have been revealed after the company started communicating with the entities interested in purchasing its all-electric truck. The pricing details come just days after Tesla revealed it planned to offer two trim levels and uncovered the specs of each.
After CEO Elon Musk said the Semi would enter volume production this year, Tesla revealed trim levels shortly thereafter. Offering a Standard Range and a Long Range trim will fit the needs of many companies that plan to use the truck for local and regional deliveries.
Tesla Semi lines up for $165M in California incentives ahead of mass production
It will also be a good competitor to the all-electric semi trucks already available from companies like Volvo.
With the release of specs, Tesla helped companies see the big picture in terms of what the Semi could do to benefit their business. However, pricing information was not available.
A new report from Electrek states that Tesla has been communicating with those interested companies and is pricing the Standard Range at $250,000 per unit, while the Long Range is priced at $290,000. These prices come before taxes and destination fees.

This is a step up from the prices that were revealed back in 2017, but with inflation and other factors, it is no surprise Tesla could not come through on the numbers it planned to offer nine years ago. When the Semi was unveiled in November 2017, Tesla had three pricing levels:
- $150,000 for a 300-mile range version
- $180,000 for a 500-mile range version
- $200,000 for a limited “Founders Series” edition; full upfront payment required for priority production and limited to just 1,000 units
Tesla has not officially released any specific information regarding pricing on the Semi, but it is not surprising that it has not done so. The Semi is a vehicle that will be built for businesses, and pricing information is usually reserved for those who place reservations. This goes for most products of this nature.
The Semi will be built at a new, dedicated production facility in Sparks, Nevada, which Tesla broke ground on in 2024. The factory was nearly complete in late 2025, and executives confirmed that the first “online builds” were targeted for that same time.
Meaningful output is scheduled for this year, as Musk reiterated earlier this week that it would enter mass production this year. At full capacity, the factory will build 50,000 units annually.

Tesla executive moves on after 13 years: ‘It has been a privilege to serve’
“It is challenging to encapsulate 13 years in a single post. The journey at Tesla has been one of continuous evolution. From the technical intricacies of designing, building, and operating one of the world’s largest AI clusters to impactful contributions in IT, Security, Sales, and Service, it has been a privilege to serve,” Jegannathan said in the post.
Tesla executive Raj Jegannathan is moving on from the company after 13 years, he announced on LinkedIn on Monday.
“It is challenging to encapsulate 13 years in a single post. The journey at Tesla has been one of continuous evolution. From the technical intricacies of designing, building, and operating one of the world’s largest AI clusters to impactful contributions in IT, Security, Sales, and Service, it has been a privilege to serve,” Jegannathan said in the post.
After starting as a Senior Staff Engineer in Fremont back in November 2012, Jegannathan slowly worked his way through the ranks at Tesla. His most recent role was Vice President of IT/AI Infrastructure, Business Apps, and Infosec.
However, it was reported last year that Jegannathan had taken on a new role, which was running the North American sales team following the departure of Troy Jones, who had held the position previously.
While Jegannathan’s LinkedIn does not mention this position specifically, it seemed to be accurate, considering Tesla had not explicitly promoted any other person to the role.
It is a big loss for Tesla, but not a destructive departure. Jegannathan was one of the few company executives who answered customer and fan questions on X, a unique part of the Tesla ownership experience.
Tesla to offer Full Self-Driving gifting program: here’s how it will work
It currently remains unclear if Jegannathan was removed from the position or if he left under his own accord.
“As I move on, I do so with a full heart and excitement for what lies ahead. Thank you, Tesla, for this wonderful opportunity!” he concluded.
The departure marks a continuing trend of executives leaving the company, as the past 24 months have seen some significant turnover at the executive level.
Tesla has shown persistently elevated executive turnover over the past two years, as names like Drew Baglino, Rohan Patel, Rebecca Tinucci, Daniel Ho, Omead Afshar, Milan Kovac, and Siddhant Awasthi have all been notable names to exit the company in the past two years.
There are several things that could contribute to this. Many skeptics will point to Elon Musk’s politics, but that is not necessarily the case.
Tesla is a difficult, but rewarding place to work. It is a company that requires a lot of commitment, and those who are halfway in might not choose to stick around. Sacrificing things like time with family might not outweigh the demands of Tesla and Musk.
Additionally, many of these executives have made a considerable amount of money thanks to stock packages the company offers to employees. While many might be looking for new opportunities, some might be interested in an early retirement.
Tesla is also in the process of transitioning away from its most notable division, automotive. While it still plans to manufacture cars in the millions, it is turning more focus toward robotics and autonomy, and these plans might not align with what some executives might want for themselves. There are a wide variety of factors in the decision to leave a job, so it is important not to immediately jump to controversy.
