SpaceX CEO Elon Musk has shown off a rarely-seen phase of Starship construction, further confirming that the next full-scale rocket ship is rapidly coming together after operator error destroyed its predecessor on April 3rd.

Around 5 am local time (10:00 UTC) on April 5th, Musk shared a photo of a smaller secondary tank’s installation inside Starship SN4’s full-size liquid methane tank. The photo is the first time SpaceX or its CEO has offered a glimpse inside this lesser-known part of Starship production and assembly and simultaneously offers insight into a design that’s been a mystery for months. Over the last few weeks, local residents-turned-unofficial-SpaceX-photographers have captured several photos of an internal Starship header tank design far removed from the nosecone tank Musk has previously discussed.

Those header tanks are a necessity to enable Starship’s ability to quickly, reliably, and safely reignite its Raptor engines for recovery and landing-related burns. For a ship like Starship SN4, those header tanks are a sign that SpaceX may want to use the ship to perform Starship’s most crucial test short of orbit — a ~20 km (12.5 mi) flight test meant to demonstrate a skydiver-style landing maneuver. While that skydiver landing test remains several consecutive milestones distant, Musk’s April 5th photo confirms that Starship SN4 is making significant progress towards final assembly.

Known as header tanks, SpaceX’s large Starship launch vehicle upper stage and orbital spacecraft requires smaller, secondary tanks aside from the main liquid oxygen and methane propellant tanks that make up the bulk of its body. In these early stages of prototype development, those tanks serve one main purpose: reserve a small portion of pressurized propellant for Starship landing burns.

While Starship’s main tanks still need to be pressurized at all times to ensure the rocket’s structural integrity, smaller header tanks make it much easier to safely feed Raptor engines fuel during even the most chaotic of aerial maneuvers. For rocket engines, even the slightest introduction of pressurization gas or voids into the combustion process can lead to immediate destruction — a bit like how a tiny air bubble can be almost instantly fatal for humans. Starship header tanks thus ensure that only a fraction of the overall tank volume is in play during the ship’s most critical maneuvers.

Requiring both a fuel and oxidizer, Starships thus need two header tanks. Currently, Starship’s design places the liquid methane header tank directly inside the main methane tank itself. The liquid oxygen header tank, however, is situated in the very tip of Starship’s nose section, a location chosen to optimize the vehicle’s center of gravity for stability during a radical skydiver-style landing maneuver.

Musk’s April 5th photo and caption revealed that SpaceX began installing Starship SN4’s methane header tank just an hour or two after it had flipped the ship’s partially-completed liquid methane tank dome. Thanks to SpaceX’s more efficient use of a common dome design in their Falcon and Starship rockets, that dome also serves as the upper dome of the ship’s larger liquid oxygen tank. After the methane header tank is installed, a funnel-like sump will be the last addition needed to finish the section.

With the majority of Starship SN4 already in work around SpaceX’s Boca Chica, Texas rocket factory, the ship could be just a week or less away from kicking off the stacking phase of assembly. Stay tuned!

Elon Musk’s new $29B Tesla stock award gets strange synopsis from governance firm

Did CGI not realize that Tesla Shareholders supported Musk being paid not once, but twice?

Elon Musk was recently awarded around $29 billion in Tesla stock as the company’s Board of Directors is attempting to get its CEO paid after his original pay package was denied twice by the Delaware Chancery Court.

But a new and strange synopsis from the Corporate Governance Institute (CGI) says the award is potentially a strength move to “endorse the will of a powerful CEO.” The problem is, in the same sentence, the firm said the new award brings up a “question of whether the board exists to steward a company in the interests of all stakeholders.”

The problem with their new analysis of Musk’s pay package is that shareholders voted twice on Musk’s original pay package of $56 billion. They voted to give Musk that sum on two separate occasions.

Musk’s original $56 billion pay package was approved by shareholders twice; once in 2018 and once again last year. Last year’s vote was in response to Delaware Chancery Court Kathaleen McCormick’s decision to revoke the “unfathomable sum” from Musk.

Shareholders still showed support for Musk getting paid. Tesla said in its new award to the CEO that this is a way to give him compensation for the first time in seven years.

CGI said in its note (via TipRanks):

“When a board builds its strategy around a single individual, it creates a concentration risk, not just operationally, but culturally and ethically. If that individual becomes a source of volatility, the company becomes fragile by design.”

What’s strange with this type of narrative is the fact that Tesla’s valuation has skyrocketed with Musk at the helm. Go back to 2020, and the stock is up over 200 percent. Since Musk’s $56 billion pay package was introduced in 2018, shares are up well over 1,000 percent.

Musk’s 2018 pay package was also not awarded to him without performance-based incentives. He was required to reach certain growth goals, all of which were accomplished through the launch of new vehicles and the advancements of its driver-assistance suites, like Autopilot and Full Self-Driving.

It is tough to agree with CGI’s perception of Musk’s new pay plan, especially as it is much less than what shareholders voted on twice. Musk deserves to be paid for his contributions to Tesla.

Tesla Robotaxi is headed to New York City, but one thing is in its way

Tesla is working to hire Vehicle Operators in New York City, but the company still needs some regulatory hurdles to go through.

Tesla Robotaxi will be headed to New York City, but there is one huge thing that stands in its way: approval to test autonomous vehicles.

Tesla is expanding its Robotaxi platform across the United States as it currently operates in Austin, Texas, and the Bay Area of California.

The company has also been seeking approvals in several other states, including Nevada, Arizona, and Florida.

However, the company is also working to expand to major metropolitan areas across the U.S. that it has not explicitly mentioned, as it attempts to reach CEO Elon Musk’s goal of giving half of the country’s population access to the platform by the end of the year:

It appears New York City is next on the list, according to a job posting on Tesla’s Careers website.

The company says it is hiring a Vehicle Operator for Autopilot in Flushing, New York, a section of the borough of Queens. Queens is connected to Brooklyn and Long Island, so it seems more ideal than launching in Manhattan or the Bronx, where traffic is heavy and charging is not as readily available.

Tesla’s job posting states:

“We are looking for a highly motivated self-starter to join our vehicle data collection team. As a Prototype Vehicle Operator, you will be responsible for driving an engineering vehicle for extended periods, conducting dynamic audio and camera data collection for testing and training purposes. Access to the data collected is limited to the applicable development team. This role requires a high level of flexibility, strong attention to detail, excellent driving skills, and the ability to thrive in a fast-paced, dynamic environment.”

It also lists the hours of operation as Tuesday through Saturday or Sunday through Thursday, with its three shifts listed as:

  • Day Shift: 6:00 AM – 2:30 PM or 8:00 AM – 4:30 PM
  • Afternoon Shift: 2:00 PM – 10:30 PM or 4:00 PM – 12:30 AM
  • Night Shift: 10:00 PM-6:30 AM or 12:00 AM-8:30 AM

We wouldn’t count on New York City being the next place Tesla launches Robotaxi. According to a report from CNBC, a spokesperson for the NYC Department of Transportation confirmed Tesla has not yet applied for permits that are needed to operate its ride-hailing service.

For what it’s worth, it could just be the first step in Tesla’s plans. It also has Vehicle Operator job postings in other regions. Houston, Texas, as well as Tampa, Miami, and Clermont, Florida, are all listed on Tesla’s Career postings.

Tesla’s Elon Musk gives nod to Ford while acknowledging his influence on EVs

“Ford basically invented mass manufacturing of large, complex products. Everyone else copied.”

Tesla CEO Elon Musk gave a tremendous nod to Ford while also acknowledging his own influence on EVs and the automotive industry in general.

Yesterday, Ford announced its new manufacturing process for EVs, which was essentially a rebirth of its own production lines and plans for more affordable models to offer consumers.

It was important to recognize that Ford truly launched automotive manufacturing with its production of the Model T 122 years ago.

That’s exactly what Musk did in a response to Ford CEO Jim Farley:

In the over 100 years since Ford started producing vehicles, the company has had one significant fact go under the radar: it truly created a great process for building large, complex vehicles. It is something that many companies eventually adopted as the car industry took off.

Tesla is in a similar situation. It has used things like the Giga Press from the Italian company IDRA to create a better, more efficient, streamlined process for building cars.

It was able to use casting to eliminate a vast majority of parts from the Model Y, which not only helped increase manufacturing efficiency but also improved safety and structural rigidity. It truly revolutionized manufacturing for the company, and Ford said that it would adopt a similar mindset with its new EVs.

Yesterday, Doug Field, the Chief EV, Digital and Design Officer for Ford, and a former Sr. VP of Engineering for Tesla, said the company was taking the mentality that “the best part is no part.”

Musk acknowledged how far it has come and how it is influencing other car companies to do the same in terms of its production strategy:

Ford is using an “Assembly Tree,” which is essentially very similar to Tesla’s “unboxed production process.” In addition to the use of Gigacasting, which Ford is calling “Unicasting,” as well as the use of structural batteries, it is almost as if Tesla is having its own “Model T moment.”

Ford has been quick to adopt an EV mentality as it plans to transition its business over the next decades. It is working to prepare for the future of the atuomotive industry, and although it has adjusted its strategy, it can’t be denied that Ford is one of the legacy automakers taking this new chapter in cars seriously.
