During an August 4th visit to SpaceX’s Boca Chica Starship build site, CEO Elon Musk captured and shared photos showing technicians carefully flipping the second of three propellant tank domes destined for installation inside the company’s South Texas orbital Starship prototype.

This is the latest visible step towards the completion of one of SpaceX’s two “Mk 1” Starships, said by Elon Musk to be the first orbit-capable prototypes. Per recent tweets, either or both of the prototypes – being built concurrently at separate sites in Florida and Texas – could be ready for their first flight tests as early as September or October 2019.

Set to be powered by up to three sea-level (SL) Raptors and three vacuum-optimized Raptors (RVacs), Musk has stated that SpaceX’s first two orbital Starship prototypes will likely begin flight testing with just the three SL engines installed. Recently, the SpaceX CEO did, however, indicate that development of Raptor’s vacuum variant – postponed as of a September 2018 update – had been reprioritized and said that it could actually be ready sooner than later.

Raptor Vacuum will have a significantly larger nozzle compared to the sea level engine it will be based on. According to Musk, RaptorVac will have a nozzle diameter of roughly 2.8m (9.2 ft), while the SL Raptor features a ~1.3m (4.2 ft)-diameter nozzle. With a larger diameter nozzle, a chemical rocket engine can technically generate more thrust and is significantly more efficient due to an increased expansion ratio, meaning the difference in the diameter of the nozzle exit and combustion chamber throat.

In the very simplest sense, this efficiency and thrust increase comes from the fact that a longer nozzle allows the exiting gas (reaction mass) to reach a higher velocity, thus conveying more momentum onto the rocket it is propelling.

Starship’s Raptor engines, of course, use liquid methane as fuel and liquid oxygen as their oxidizer. According to SpaceX, fully fueling a combined Super Heavy and Starship stack will require an incredible ~5000 tons (11 million pounds) of propellant – ~1500 tons for Starship and ~3500 tons for Super Heavy.

To contain such a huge amount of fuel and oxidizer, Starship (and Super Heavy) must effectively be turned into extremely mass-efficient pressure vessels, capable of supporting something like 20 kilograms of propellant with every kilogram of rocket structure.

SpaceX’s installation of bulkheads in the Texas Starship prototype are thus an inherent indication that the rocket is being readied to play the role of a massive, ultra-strong pressure vessel. While sitting vertically, a fueled Starship’s tank domes will be subjected to immense pressures and forces from the sheer weight of the liquid oxygen and methane held above them.

Additionally, the rearmost dome will likely be partially or fully integrated into Starship’s thrust structure, meaning that it will simultaneously be subjected to the thrust of 3-6 Raptors (as much as 600-1200 tons of thrust) and the gravity of 300 metric tons of methane. It’s unclear if SpaceX is planning to reinforce Starship and Super Heavy tank bulkheads with structural add-ons, but it’s safe to assume that some level of reinforcement will be required.

SpaceX CEO Elon Musk’s planned August 24th presentation on Starship and Super Heavy will likely (hopefully) provide some new details on the structure and general design of the company’s advanced, next-generation rocket.

Tesla Board takes firm stance on Elon Musk’s political involvement in pay package proxy

But there was one driving factor that was considered critical to Tesla: “Receive assurances that Musk’s involvement with the political sphere would wind down in a timely manner.”

The Tesla Board of Directors announced yesterday that it had established a new pay package for CEO Elon Musk, as it believes it is “critical” to secure his long-term commitment to the position.

However, the Board made it clear about Musk’s political involvement in its proxy filing, which announced the new pay package, and it seems the company is addressing it directly.

Elon Musk’s new pay plan ties trillionaire status to Tesla’s $8.5 trillion valuation

The proxy announced the massive pay package, which could give Musk $1 trillion if he achieves various goals that would help Tesla grow as an automaker, energy provider, and in the Robotics and AI sectors.

There are also some details about the Board’s decision, which we went over yesterday, as it felt that Musk was the right person to continue to lead Tesla for the foreseeable future.

It appears that there were four primary reasons behind the decision to retain Musk with this substantial pay package.

Tesla sought to secure Musk’s commitment to the company by offering him a path to increased ownership; if he were to achieve all tranches, he would hold approximately 27 percent ownership.

Another was to let Musk develop the newest Master Plan, which was released last week. Additionally, there needs to be a “meaningful framework for long-term succession planning led by the Board with Musk’s active participation.”

But there was one driving factor that was considered critical to Tesla: “Receive assurances that Musk’s involvement with the political sphere would wind down in a timely manner.”

It is far from a secret that Musk’s involvement with President Donald Trump during his election campaign and after he was voted in rubbed many people the wrong way.

Musk was part of President Trump’s White House, serving as the Head of the Department of Government Efficiency (DOGE) and also acting as a Special Advisor.

Musk’s political involvement impacted sales, but by how much is unknown.

It appears the Board is truly ready to move on from politics and focus on what matters: expanding AI, Robotics, and sustainable energy. For what it’s worth, Musk has backed away from politics significantly compared to how it was during election season.

Tesla has officially launched a new Supercharger program in the United States, catering to business owners who are sure to love it.

Tesla’s Supercharger Network is the world’s most expansive electric vehicle charging network, with over 70,000 locations worldwide. EV owners can also access other networks, making the charging experience well-rounded and available at nearly every location imaginable.

The company is now taking things a step further by launching “Supercharger for Business,” a new way to enable fast-charging for Teslas and other EVs through stalls that are owned by you but managed by the company.

Tesla Superchargers get massive nod in new study showing reliability

“Purchase and install Superchargers at your business,” Tesla writes on a page on its website for the new program. “Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”

There are several advantages to this program that benefit owners, customers, and employees alike. It is truly a great opportunity for everyone involved.

For company owners, the presence of Superchargers is extremely beneficial for customers, as it can be a convenient way to attract people to your business. It will also provide your employees who drive EVs with a fast and convenient way to charge at work, making your business a more attractive place to work.

The stalls are also customizable, and can have your company’s logo placed on the charger:

For customers, they will be able to pull up to your business for a meeting or a visit and charge during their stop. EV owners know how convenient this would be.

For employees, they can now fast-charge at work. It is a huge benefit to have this available. It can also be more convenient than typical chargers at offices, which usually have a lower power output and take hours to gain range. In a pinch, the Superchargers will be more convenient.

Businesses also have the ability to control everything they want with the Superchargers, including pricing, while also benefiting from Tesla’s management and maintenance of the stalls:

“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”

With EVs becoming more popular every year, this is something that many businesses will take advantage of to not only gain customers, but also potentially sway an employee to their company for employment.

Not to mention, this is a great advertising opportunity for businesses.

Tesla board reveals reasoning for CEO Elon Musk’s new $1 trillion pay package

“Yes, you read that correctly: in 2018, Elon had to grow Tesla by billions; in 2025, he has to grow Tesla by trillions — to be exact, he must create nearly $7.5 trillion in value for shareholders for him to receive the full award.”

Tesla’s Board of Directors has proposed a new pay package for company CEO Elon Musk that would result in $1 trillion in stock offerings if he is able to meet several lofty performance targets.

Musk, who has not been meaningfully compensated since 2017, completed his last pay package by delivering billions in shareholder value through a variety of performance-based “tranches,” which were met and resulted in the award of billions in stock.

Elon Musk’s new pay plan ties trillionaire status to Tesla’s $8.5 trillion valuation

However, Musk was unable to claim this award due to a ruling by the Delaware Chancery Court, which deemed the payout an “unfathomable sum.”

Now, the company is taking steps to ensure Musk gets paid, as the Board feels that it is crucial to retain its CEO, who has been responsible for much of the company’s success.

This is not a statement to undermine the work of all of Tesla’s terrific employees, but a ship needs to be captained by someone, and Musk has proven he is the right person for the job.

The Board also believes that, based on a statement made by the company in its proxy, various issues will be discussed during the upcoming Shareholder Meeting.

Robyn Denholm and Kathleen Wilson-Thompson recognized Musk’s contributions in a statement, which encouraged shareholders to vote to approve the payout:

“We’re asking you to approve the 2025 CEO Performance Award. In designing the new performance award, we explored numerous alternatives. Ultimately, the new award aims to build upon the success of the 2018 CEO Performance Award framework, which ensure that Elon was only paid for the performance delivered and incentivized to guide Tesla through a period of meteoric growth. The 2025 CEO Performance Award similarly challegnes Elon to again meet a series of even more aspirational goals, including operational milestones focused on reaching Adjusted EBITDA targets (thresholds that are up to 28 times higher than the 2108 CEO Performance Award’s top Adjusted EBITDA milestone) and rolling out new or expanded product offerings (including 1 million Robotaxis in commercial operation and delivery of 1 million AI Bots), all while growing the company’s market capitalization by trillions of dollars.

Yes, you read that correctly: in 2018, Elon had to grow Tesla by billions; in 2025, he has to grow Tesla by trillions — to be exact, he must create nearly $7.5 trillion in value for shareholders for him to receive the full award.

In addition to these unprecedented performance milestones, the 2025 CEO Performance Award also includes innovative structural features, born out of the special committee’s considered analysis and extensive shareholder feedback. These features include supercharged retention (at least seven and a half years and up to 10 years to vest in the full award), structural protections to minimize stock price volatility due to administration of this award and, thereafter, incentives for Elon to participate in the Board’s continued development of a framework for long-term CEO Succession. If Elon achieves all the performance milestones under this principle-based 2025 CEO Performance Award, his leadership will propel Tesla to become the most valuable company in history.”

Musk will have a lot of things to accomplish to receive the 423,743,904 shares, which are divided into 12 tranches.

However, the Board feels he is the right person for the job, and they want him to remain the CEO. This package should ensure that he stays with Tesla, as long as shareholders feel the same way.
