First noticed by NASASpaceflight.com forum member “exilon”, SpaceX appears to have selected off-the-shelf Tesla battery packs as the power storage method of choice for its Starship Mk1 prototype, currently in the midst of a busy period of integration

Potentially taken directly from Tesla Model S/X powertrains otherwise headed for recycling, SpaceX technicians have spent the last 24 or so hours attaching numerous battery packs to part of a Starship subsystem known as header tanks. This is the latest addition to SpaceX and Tesla’s relatively close relationship – the two have begun to work together to solve challenges with materials science, batteries, and more within the last 12-24 months.

While initially surprising, the appearance of battery packs quite literally taken from Tesla Model S/X vehicles or their Gigafactory assembly line actually makes a lot of sense. By using prepackaged, off-the-shelf battery systems with industry-leading power management capabilities, SpaceX is probably saving a huge amount of time, money, and effort. If the battery packs were already nearing the end of their useful automotive lives, the net cost could very well approach zero, aside from what looks like a minimal mounting brace. It’s possible that SpaceX has even pursued modifying and certifying large Tesla-derived battery packs for use on orbital Starship missions.

These battery packs were spotted by an eagle-eyed forum user who was first to recognize the hardware for what it likely was. Per the above photo, SpaceX appears to have joined two self-contained Tesla battery packs into single units that were then installed on a header tank. Knowing that the highest capacity Tesla offers is ~100 kWh, the 2×2 packs could store up to 400 kWh and offer instantaneous power output (ignoring thermal limitations) well into the megawatt (MW) range. It’s unclear if the first header tank also had batteries attached but SpaceX technicians began installing that tank inside Starship’s nose cone on the evening September 22nd. Tank #2 will likely follow in the next 24 hours per Musk’s indication that Starship Mk1 would be stacked to its full height on Wednesday.

For unknown reasons, SpaceX is choosing to mount the ~1000 kg (2200 lb) battery pack pairs directly onto the outside of one of Starship Mk1’s two header tanks. These tanks compliment the rocket prototype’s main propellant tanks and are meant to serve as small reserves of fuel (methane) and oxidizer (oxygen) that can be pressurized independently. During dramatic in-space and in-atmosphere maneuvers, the g-forces exerted on Starship could easily find the vehicle’s propellant pushed away from the ‘bottom’ of its main tanks, creating bubbles or voids that can damage and destroy rocket engines if ingested.

Pressurizing the entirety of the main tanks (a cylinder measuring 9m by ~40m or 30×130 ft) is extremely impractical – hence the need for much smaller header tanks. Falcon 9 boosters are able to sidestep this issue because they are small and light enough (relatively speaking) that cold gas thrusters can efficiently generate the positive Gs needed to safely ignite its engines for recovery and landing maneuvers. Empty, Starship alone will likely weigh no less than 4-6 times as much as a Falcon 9 booster (~25 tons, 55,000 lb).

According to CEO Elon Musk, SpaceX has decided to install those header tanks in the very tip of Starship Mk1’s conical nose to help balance out the vehicle’s center of mass. As a side-effect, SpaceX will have to install feed lines that run the entire length of the spacecraft and protect them with steel aero-covers. It’s unclear if this design choice is necessitated by Starship’s early, prototypical form or if – once outfitted with crew quarters or a functional cargo bay – it’s possible that that added mass will serve as enough of a counterbalance to preclude the need for ballast in the nose.

Tesla analyst: ‘near zero chance’ Elon Musk’s $1T comp package is rejected

“There is a near-zero chance that $TSLA shareholders will vote down Elon’s new proposed comp plan at the Nov 6 shareholders’ meeting.”

A Tesla analyst says there is “zero chance” that CEO Elon Musk’s new compensation package is rejected, a testament to the loyalty and belief many shareholders and investors have in the frontman.

Tesla investors will vote on November 6 at the annual Shareholder Meeting to approve a new compensation package for Musk, revealed by the company’s Board of Directors earlier this month.

The package, if approved, would give Musk the opportunity to earn $1 trillion in stock, an ownership concentration of over 27 percent (a major request of Musk’s), and a solidified future at the company.

The Tesla Community on X, the social media platform Musk bought in 2023, is overwhelmingly in favor of the pay package, though a handful of skeptics remain.

Nevertheless, the big pulls of this vote are held by proxy firms and other large-scale investors. Two of them, Institutional Shareholder Services (ISS) and Glass Lewis, said they would be voting against Musk’s proposed compensation plan.

Today, the State Board of Administration of Florida (SBA) said it would vote in favor of Musk’s newly-proposed pay day, making it the first large-scale shareholder to announce it would support the CEO’s pay.

One analyst said that Musk’s payday is inevitable. Gary Black of the Future Fund said today there is a “near-zero chance” that shareholders will allow Musk’s pay package to be rejected:

There is a near-zero chance that $TSLA shareholders will vote down Elon’s new proposed comp plan at the Nov 6 shareholders’ meeting.”

He added an alternative perspective from Wedbush’s Dan Ives, who said that he had a better chance of starting for the New York Yankees than the comp package not being approved.

Black’s the Future Fund sold its Tesla holdings earlier this year. He explained that the firm believed the company’s valuation was too disconnected from fundamentals, citing the P/E ratio of 188x and declining earnings estimates.

The firm maintained its $310 price target, and shares were trading at $356.90 that day.

Shares closed at $452.42 today.

The latest predictions from betting platform Kalshi have shown Musk’s comp package has a 94 percent chance of being approved:

Tesla gains massive vote of confidence on compensation plan for Elon Musk

“”The SBA supported Tesla’s 2018 performance award proposal and reaffirmed that support in the 2024 Tesla shareowner vote. The total return on Tesla’s stock after enactment of its 2018 performance award and the prior history of incentive structured plans leads us to strongly support the proposed 2025 CEO performance award.”

Tesla gained a massive vote of confidence on its proposed $1 trillion compensation plan for CEO Elon Musk from the State Board of Administration of Florida (SBA) on Monday.

On Monday, the SBA submitted a filing to the Securities and Exchange Commission (SEC) stating that it would vote to support Musk’s compensation plan, just as it did with the 2018 performance award and its second vote last year:

“The SBA supported Tesla’s 2018 performance award proposal and reaffirmed that support in the 2024 Tesla shareowner vote. The total return on Tesla’s stock after enactment of its 2018 performance award and the prior history of incentive structured plans leads us to strongly support the proposed 2025 CEO performance award. We believe the proposed award continues to promote an aggressive strategy to align incentives between management and shareowners and focuses solely on pecuniary factors and long-term shareowner value creation.”

This is the first large-scale shareholder that has come out and supported Musk’s potential compensation plan, which was outlined by Tesla and its Board of Directors earlier this month.

Most of the news surrounding Musk’s pay plan has been the opposite of what the SBA said today, as Institutional Shareholder Services (ISS) and Glass Lewis, two proxy firms, said they would be voting against the compensation package.

Musk replied to their vote last week during the Q3 Earnings Call, calling them “corporate terrorists.”

He said:

“I just don’t feel comfortable building a robot army here and then being ousted because of some asinine recommendations from ISS and Glass Lewis, who have no freaking clue. I mean, those guys are corporate terrorists. The problem, yeah. Let me explain, like, the core problem here is that so many of the index funds, passive funds, vote along the lines of whatever Glass Lewis and ISS recommend. They’ve made many terrible recommendations in the past. If those recommendations had been followed, they would have been extremely destructive to the future of the company.”

SBA’s perspective on the plan relies on what Musk has done in the past decade with Tesla, as he has driven company growth, increased shareholder value, and kept the company on track with its lofty and ambitious goals.

It also outlined nine reasons to support Musk’s compensation:

  1. Pure Pay for Performance Design – Entirely Performance-Based, aligns with Shareowners
  2. Size of the Award and Share Count – Performance-based allocation, dilution tied to value creation, structured milestone design
  3. Market Capitalization Milestones – Clear, tiered targets, sustained performance requirement, shareholder value focus
  4. Operational/Product Milestones – Clear, quantifiable goals, strategic product focus, financial discipline, multi-quarter evaluation windows
  5. Vesting/Holding Periods – Long-term vesting structure, mandatory holding period, continuous service requirement
  6. CEO Succession – Succession planning requirement, performance integrity safeguard
  7. Time Horizon and Duration – Extended performance window of 10 years, no intermediate vesting
  8. Dilution & Voting Power Implications – Potential for significant ownership increase, permanent dilution
  9. Ambition and Stretch Goals – Extraordinary Scale of Growth, Shareowner value focus

Shareholders will vote on Musk’s compensation package on November 6 at the annual Shareholder Meeting.

Tesla Optimus gets its latest job, and it’s not in the company’s factories

Tesla Optimus was spotted in its latest job placement, not at any of the company’s manufacturing or production facilities.

Optimus was instead spotted in New York City at Times Square, handing out Halloween candy to people:

It is not Tesla Optimus’s first gig in the service industry, as it has already secured several employment opportunities through the company’s projects. Last year, it served drinks at the company’s We, Robot day, where the Cybercab and Robovan were unveiled.

Additionally, Optimus has been helping out at the Tesla Diner in Los Angeles, serving popcorn and greeting guests.

Optimus has many capabilities, and its applications can benefit both residential and commercial users. It is designed to be an at-home assistant, helping with tedious, monotonous tasks around the house.

In a commercial setting, Optimus will be programmed to handle everything from manufacturing to other factory-type tasks, as Tesla has already been using the robot in its own factories for smaller jobs.

Optimus has been in development for several years, but Tesla is ready to turn up the heat in terms of its capabilities and engineering as it prepares to launch it to a wider audience in the coming years.

During the recent Q3 Earnings Call, Tesla CEO Elon Musk gave updates on the Optimus project, highlighting its progress and the company’s current development status.

Musk said that Tesla is “on the cusp of something really tremendous with Optimus, which I think is likely to be, has the potential to be, the biggest product of all time.” He also mentioned that Tesla is in an interesting position because not only has it established itself as one of the biggest car companies in the country, but it’s the only company that manufactures vehicles and has a monumental grasp of the importance of AI and robotics.

“I’m unaware of any robot program by Ford or GM or, you know, by U.S. car companies,” he said.

Musk added that Optimus has some pretty big responsibilities around Tesla’s factories:

“I mean, bringing Optimus to market is an incredibly difficult task, to be clear. It’s not like some walk in the park. At some point, I mean, actually, technically, Optimus can walk in the park right now. We do have Optimus robots that walk around our offices at our engineering headquarters in Palo Alto, California, basically twenty-four hours a day, seven days a week.”

Right now, it appears Tesla is having its biggest challenge with the Optimus project around the development of its hands and forearms, which Musk called “an incredible thing” on the human body:

“The human hand is an incredible thing. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason…Making the hand and forearm, because most of the actuators, just like the human hand, the muscles that control your hand are actually primarily in your forearm. The Optimus hand and forearm are an incredibly difficult engineering challenge. I’d say it’s more difficult than the rest of the robot from an electromechanical standpoint.”

Tesla is stumped on how to engineer this Optimus part, but they’re close

Optimus is starting to get more visibility in the public, and Tesla’s move to put it smack dab in the middle of New York City is one that will certainly bring some additional eyes to its development.
