After weeks of exceptionally cautious buildup, SpaceX’s first orbital-class Starship prototype has repeatedly broken new ground tests in the first few hours of its first static fire test window.

SpaceX first installed Starship S20 on one of two suborbital launch and test stands more than two months ago. After almost six weeks of largely invisible work, longer than any other new Starship prototype has spent inactive at Starbase launch facilities, Ship 20 came to life for the first time during a ‘pneumatic proof’ test completed on September 27th. Two days later, put the Starship through a complex cryogenic proof test, loading supercool liquid nitrogen instead of ambient-temperature gas and simulating the thrust of six Raptor engines with hydraulic rams.

According to CEO Elon Musk, Ship 20 passed its first ‘cryoproof’ without issue, opening the door for static fire testing with real methane and oxygen (LCH4/LOx) propellant and Raptor engines. However, for unknown reasons, it would ultimately take SpaceX more than three weeks of additional work to prepare Starship S20 for its first engine-involved test.

On October 19th, near the end of a seven-hour test window, Starship S20 sort of fired up for the first time, completing what is known as a preburner test. Effectively the first half of static fire test without full ignition, it was nevertheless the first time a Raptor Vacuum engine was operated on a Starship prototype. Originally, based on road closures scheduled with Cameron County, Texas, that preburner test and associated static fire testing was initially scheduled to begin as early as Friday, September 31st.

SpaceX continued to file for and cancel closures throughout the next week, culminating in a few local residents receiving a routine safety notice about a possible test on October 13th. That attempt was canceled soon after and SpaceX ultimately distributed alerts for tests on October 14th and October 18th. Ship 20’s first preburner test was completed on the 19th, followed by another soon-to-be-rescinded notice on the 20th.

Finally, after perhaps the windiest road yet for a Starship from cryoproof to static fire, Starship S20 sailed through a static fire test flow on October 21st and ultimately fired up for the first time ever at 7:16 pm CDT (00:16 UTC). In perfect opposition to weeks of unprecedentedly slow testing, Starship S20 not only completed its first true static fire early in the test window, but it completed the first on-vehicle static fire of a Raptor Vacuum engine and then, just over an hour later, performed a second static fire – this time simultaneously igniting both a Raptor Vacuum and Raptor Center (sea-level-optimized) engine. Aside from also marking the first time that two Raptor variants have been simultaneously fired on the same vehicle, Starship S20’s two-test surprise was technically the fastest back-to-back static fire SpaceX has ever completed, beating Starship SN9 by about 15 minutes.

Back in January 2021, SN9 completed an unprecedented three back-to-back-to-back Raptor static fires in less than 100 minutes as part of what Musk described as “[a day] about practicing Starship engine starts.” SN9 ultimately completed two of those tests in 75 minutes, setting a niche but still impressive turnaround record. Starship S20, however, managed two static fires in 62 minutes on October 21st.

With any luck, Ship 20’s unexpected first-test milestones will mark the start of a more energetic period for the orbital-class prototype, potentially building up to the first Starship static fire with more than three Raptors and the first test with all six engines installed. Super Heavy Booster 4 is also well overdue for its own proof and static fire test campaign, virtually all of which will be new territory for SpaceX.

IF Metall chair to Elon Musk: “Give us a chance” as Tesla Sweden strike hits 2 years

The official emphasized that Swedish unions function under a cooperative framework that benefits both employers and workers.

IF Metall’s strike against Tesla Sweden has entered its third year, with union chair Marie Nilsson urging Elon Musk to reconsider his perception of organized labor. 

Speaking ahead of the strike’s second anniversary, Nilsson stated that Tesla should understand that Swedish unions operate differently from their American counterparts, and they deserve the opportunity to prove it.

IF Metall leader urges Tesla to understand Sweden’s system

In an interview with Dagens Arbete (DA), Nilsson stated that Tesla’s skepticism toward labor unions likely stems from the company’s experience in the United States, where labor organizations have historically taken a more combative approach. She emphasized that Swedish unions function under a cooperative framework that benefits both employers and workers.

“I can certainly understand that Elon Musk and Tesla are skeptical of the trade union movement. They have experience with American unions that operate in a completely different environment and that have to be militant in a different way. 

“I would say: Don’t compare Swedish unions with American ones. Let’s give us a chance. Signing a collective agreement in Sweden also does not mean that you are committed to collective agreements in the rest of the world, but it is the practical system we have here to regulate the conditions,” Nilsson stated.

Nilsson rejected the idea that Tesla Sweden is being unfairly targeted

The IF Metall leader also reflected on the conflict’s duration, calling it unprecedented in Swedish labor history. While she admitted the union should have organized Tesla workers earlier, she maintained that the movement remains determined. “No one can possibly imagine what it is like not to go to work for two years,” Nilsson said, praising members who have continued to maintain their protest against the EV maker.

Nilsson also rejected any notion that the union is targeting Tesla unfairly. “Tesla is not a poor little company that we are trying to crush in any way,” she said. “But this is a global player, and we cannot accept that they should have different conditions in Sweden than other entrepreneurs have.” 

She confirmed that IF Metall is now prepared to take greater risks, especially after the Swedish Mediation Institute stepped back from talks. “It is impossible for us to do anything else. This is a large and important player, and therefore we need to take this conflict. It is impossible for us to do anything else,” Nilsson said.

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.

Tesla CEO Elon Musk’s $1 trillion pay package hits first adversity from proxy firm

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.
