SpaceX's Elon Musk works through holidays on Starship's "most difficult part"
SpaceX CEO Elon Musk says he has been working through the holidays at the company’s Boca Chica facilities to get Starship’s “most difficult part” ready for the next-generation spacecraft’s next prototype and flight tests.
Known as tank domes or bulkheads, Musk says that the hardware is the most difficult part of building and assembly Starship’s primary structure, referring to the steel engine section, tanks, and pointed nose that comprise most of the spaceship’s body. Starship’s primary structure must stand up to the rigors of all aspects of flight, including highly-pressurized propellant tanks, extreme G-forces during launches, orbital reentry, and more.
It was never officially determined whether the failure was intentional or not but during the first Starship prototype’s (Mk1) last test campaign, the vehicle experience an overpressure event while being filled with liquid oxygen or nitrogen. Localized to the weld connecting the upper tank dome to Starship’s cylindrical tank section, the dome essentially sheared off at the weld and launched hundreds of feet into the air, sending a shockwave through the vehicle that crumpled many of its steel structures as if they were aluminum foil.
It’s likely that Starship Mk1’s failure was an intentional overpressure event, meaning that SpaceX may have purposely pressed the vehicle’s tanks beyond their design limits to determine how structurally sound they were. What is less clear is whether the rocket burst before or after reaching its theoretical design limit.
For reference, SpaceX’s Falcon 9 rocket operates with its fuel and oxygen tanks pressurized to about 50 psi (3.5 atm) with localized pressures likely doubling or tripling near the bottom of both tanks during the first minute or two of launch. Some amateur back-of-the-envelope calculations from videos of Starship Mk1’s burst event suggest that it was pressurized to at least 60-75 psi (4-5 atm) at its upper tank dome, meaning that the pressure on its two lower domes and tank walls would have been even higher. If correct, those unofficial figures mean that Mk1 actually performed quite well considering the ramshackle facilities and unprecedentedly spartan methods used to fabricate and assemble it.
As such, Musk likely considers Starship’s tank domes the “most difficult part of [its] primary structure” in large part because of how difficult it is to make giant propellant tank domes simultaneously light and strong. Musk has previously implied that Starship Mk1 was more 200 tons (450,000 lb) empty while the ultimate goal for the spacecraft’s empty weight is closer to 120 tons, and a large portion of that weight savings will likely have to come from making its tank domes as light as possible.
In line with that educated speculation, the last month or so of SpaceX’s Starship work in Boca Chica, Texas has been marked by a distinct focus on building tank domes. In fact, Musk himself tweeted that he had worked all night with SpaceX engineers in Boca Chica in a bid to get dome production ready for Starship’s Mk3 prototype, the first Super Heavy hardware, and many more rockets to come.
Prior to Musk’s tweet, a Starship tank dome was actually shipped all the way from Florida to Texas and arrived earlier this month. Meanwhile, technicians have been briskly building up an additional dome using what appears to be a different method of integration involving new parts. SpaceX is currently attempting to weld Starship’s tank domes together from several dozen pre-formed sheets of stainless steel.
The sheets of steel assembled into the dome Musk showed on December 27th likely arrived in Boca Chica on December 13th, implying that SpaceX has managed to complete the majority of the first dome prototype – using a new process – in barely two weeks.
After SpaceX lifted the partially-completed dome off one of its custom assembly jigs, workers almost instantly began staging new sections of steel, beginning the process of integrating yet another tank dome – now likely the fourth on-site in Boca Chica. Meanwhile, at a nearby section of SpaceX’s Boca Chica production facilities, yet another dome was visible on the 28th. In short, SpaceX should soon have more than enough tank domes to complete the next Starship prototype – said to be a significantly improved and refined design compared to Mk1.
Known as Starship Mk3 (or Starship SN01), Musk says that the rocket – currently just a miscellaneous collection of separate parts – could (“hopefully”) be ready for its first flight as soon as February or March 2020.

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:
- Pure Pay for Performance Design – Entirely Performance-Based, aligns with Shareowners
- Size of the Award and Share Count – Performance-based allocation, dilution tied to value creation, structured milestone design
- Market Capitalization Milestones – Clear, tiered targets, sustained performance requirement, shareholder value focus
- Operational/Product Milestones – Clear, quantifiable goals, strategic product focus, financial discipline, multi-quarter evaluation windows
- Vesting/Holding Periods – Long-term vesting structure, mandatory holding period, continuous service requirement
- CEO Succession – Succession planning requirement, performance integrity safeguard
- Time Horizon and Duration – Extended performance window of 10 years, no intermediate vesting
- Dilution & Voting Power Implications – Potential for significant ownership increase, permanent dilution
- 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 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.
Tesla analysts are expecting big things from the stock (NASDAQ: TSLA) after many firms made price target adjustments following the Q3 Earnings Call.
Last Wednesday, Tesla reported earnings with record revenue but missed EPS estimates.
It blew delivery expectations out of the water with its strongest quarter in company history, but Tesla’s future relies on the development of autonomous vehicles, robotics, and AI, which many bullish firms highlight as major strengths.
The earnings call reiterated those points, along with the belief that Tesla CEO Elon Musk should be rewarded with a newly proposed pay package that would enable him to gain $1 trillion in wealth if he comes through on a lengthy list of performance tranches.
Nine Wall Street firms made adjustments to their outlook on Tesla shares in the form of price target increases since last Wednesday’s call, all of which are indications of big expectations for the stock moving forward.
Here are the nine firms that made moves:
- Truist – $280 to $406, reiterated Hold rating
- Roth MKM – $395 to $404, reiterated Buy rating
- Cantor Fitzgerald – $355 to $510, reiterated Overweight rating
- Deutsche Bank – $435 to $440, reiterated Buy rating
- Mizhuo – $450 to $485, reiterated Outperform rating
- New Street Research – $465 to $520, reiterated Buy rating
- Evercore ISI – $235 to $300, reiterated In Line rating
- Freedom Capital Markets – $338 to $406, upgraded to Hold rating
- China Renaissance – $349 to $380, reiterated Hold rating
The boosts in price target are largely due to Tesla’s future projects, as Roth MKM, Cantor Fitzgerald, Mizuho, New Street Research, and Evercore ISI all explicitly mention Tesla’s autonomy, robotics, and AI potential as the main factors for its price target boosts.

It is no surprise that many firms are adjusting their outlook on Tesla shares considerably in an effort to prepare for the company’s transition to even more of a tech company than a car company.
The issue with many analysts is that they treat the company’s vehicle deliveries as the main indicator of value.
However, Tesla has a robust energy division, which was a major contributor to the company’s strong margins and gross profit in Q3, as well as its prowess in robotics and AI.
Additionally, the company is seen as a key player in the autonomy field, especially after launching driverless rides on a Robotaxi platform in Austin and expanding a similar program in the Bay Area.
Tesla shares were up over 5 percent at 12:18 p.m. on the East Coast.
