SpaceX begins installing ‘Mechazilla’ arms designed to catch Starship rockets

After a busy few weeks spent attaching Mechazilla’s two rocket-catching arms to a carriage-like backbone, SpaceX has begun the process of installing the integrated structure on Starbase’s ~450 ft (~135m) tall Starship ‘launch tower’.

Once complete, SpaceX will have created a first-of-its-kind launch tower designed to stack and manipulate Starships and Super Heavy boosters in far worse conditions than cranes can tolerate and catch both rocket stages out of mid-air. Referred to internally as ‘chopsticks,’ the giant pair of steel arms will join a third ‘quick disconnect’ (QD) arm tasked with stabilizing Super Heavy during Starship installation and feeding the reusable upper stage power, comms links, and some 1200 tons (~2.65M lb) of propellant.

Together, they will enable SpaceX to attempt Starship’s first orbital test flights and, perhaps one day, help the next-generation rocket launch in almost any weather and achieve unprecedentedly rapid reusability. But first, SpaceX needs to finish installing and rigging the massive structure.

Beginning on August 29th after less than three months of assembly, SpaceX installed Starship’s QD arm on the launch tower. About a month later, the QD arm was mostly finished off with the installation of a claw-like grabber meant to stabilize Super Heavy and is now only missing its namesake quick-disconnect (an actuating device that will connect Starship to the pad and rapidly disconnect at liftoff). Assembly of the last three major components of Mechazilla – a carriage-like structure and two giant arms – began in July and, much like the tower’s QD arm, wrapped up about three months later.

On October 6th, SpaceX began combining those three main parts by flipping the carriage – a bit like a spine and ribcage with ‘skates’ that attach to rails on the launch tower’s legs – vertical and staging it on a temporary support structure. Both ‘chopsticks’ were then flipped into the correct orientation and moved into position with separate cranes for installation on the carriage/backbone. From start to finish, that process took around 9-10 days and culminated with the installation of two giant cylindrical pins with built-in bearings on October 14th and 15th. By the 17th, both cranes had detached from the assembled Mechazilla arms and carriage were, leaving it precisely balanced against the support structure and more or less freestanding.

Just a few days later, after a last-second attempt on October 19th was called off as night fell, SpaceX tried again on the 20th and completed the first step of installing Mechazilla’s catch arms on the launch tower without apparent issue. Likely weighing several hundred tons, Starbase’s largest crane lifted the massive structure up and over an adjacent launch mount and then carefully inched it closer to the tower. Prior to the lift, SpaceX technicians staged 12 ‘skates’ on three of the tower’s four legs – two upper and two lower skates per leg.

Once the carriage was in the right position, workers were able to wrap its upper arms around the tower and began connecting the carriage to those skates with several more large pins. It’s unclear how much progress was made in the hours after the lift but it appears that the carriage has been attached to maybe four or five of six upper skates. Work continued well after nightfall, meaning that it will likely only take a few days to complete all 12 connections. However, even after all skates are installed, the carriage, arms, and skates will still be hanging by crane or winch.

To truly install the structure on the tower, SpaceX will have to finish installing and rigging thousands of feet of steel cable that – via a complex system of pulleys – will connect to powered ‘drawworks’ that will support the carriage and catch arms and lift the assembly up and down the tower like an elevator car. The catch arms and carriage will also need to be mated with a giant ‘cable carrier’ (already staged on the tower) that will connect the structure to ground and control systems.

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.

Elon Musk reveals big plans for Tesla Optimus at the Supercharger Diner

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

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.
