SpaceX crushes rocket engine world record during Raptor test

Published

on

CEO Elon Musk has revealed that SpaceX crushed a global rocketry record during a recent Raptor engine test, pushing the crucial Starship component past years-old performance targets.

On August 17th, the SpaceX CEO unexpectedly released a photo of a Raptor test and a corresponding graph showing the engine’s chamber pressure, confirming that the company had successfully pushed the engine to record-breaking levels. Musk says that an unspecified Raptor – possibly serial number 39 (SN39) – briefly reached a main combustion chamber pressure of 330 bar (~4800 psi) during a controlled burn – and remained intact after shutdown.

Outside of subscale laboratory tests, the highest main combustion chamber known to full-scale, orbital-class rocketry was achieved by the Soviet Union in the 1980s with the RD-701 engine. Although the exceptionally unique engine was canceled before it could be used, it reportedly reached pressures of 290-300 bar in one mode of operation. Now, however, SpaceX and its Raptor engine appear to be the new world record holders – and by a huge margin.

Raptor’s new crown comes roughly 18 months after Elon Musk revealed that the engine had beaten the Soviet RD-270 full-flow staged combustion (FFSC) with a higher sustained chamber pressure (~257 bar vs 255 bar). A few days later, the same Raptor went even further, cresting the Russian RD-180 engine’s 257 bar operating pressure with a peak of 268 bar. Still, SpaceX needed 6-12 more months to refine Raptor into an engine capable of operating even close to those pressures for more than ~10 seconds. In July and August 2019, Raptor engine SN6 flew twice on Starhopper, culminating in a ~60-second, 150-meter hop that ended with the engine nearly destroying itself seconds before landing.

Almost exactly one year later, Raptor SN27 launched on Starship SN5 on the same 150m trajectory and appeared to perform flawlessly. Exhibiting barely a stutter or flare, SN27 never came close to the flamethrower-like death throes Raptor SN6 suffered in August 2019. In short, SpaceX continued to do what SpaceX does best, continuously refining rough prototypes into increasingly polished end products.

Originally revealed in 2016 as a methane/oxygen full-flow staged combustion engine with an operating combustion chamber pressure of 300 bar (4350 psi), Raptor’s August 17th achievement means that SpaceX has already exceeded one of its performance goals. Of course, combustion chamber pressure is significant but still far less important than engine longevity, burn duration limits, and reusability in the context of Starship. SpaceX likely wouldn’t be pushing the envelope of chamber pressure if it wasn’t confident about Raptor’s many other important attributes, but it’s still unknown if Raptor has ever burned for longer than ~90 seconds.

Regardless, if Raptor can actually sustain chamber pressures of 330 bar without damaging itself, the milestone could mean that SpaceX has already boosted Raptor’s maximum thrust from ~200 metric tons to ~225 metric tons (440,000-500,000 lbf. For Starship and Super Heavy, that 10% increase in thrust could easily translate to a 5-10% increase in payload to orbit per launch.

To reach orbit, though, Raptor still has a ways to go. For Super Heavy to be able to complete a normal launch, SpaceX will need to dramatically expand Raptor production (~31 engines per booster) and ensure that Raptor can reliably operate for 3-5+ minutes and reignite multiple times in flight. For Starship, SpaceX needs – at the minimum – to mature Raptor until it can burn continuously for 5-10 minutes to reach orbit. The company will likely also need to finish developing a custom vacuum-optimized version of Raptor for efficient orbital Starship flights.

Given just how quiet SpaceX is about most Raptor milestones, there’s a chance the company has already made substantial progress along those lines. For example, Starship SN8 – already well on its way to completion – will likely be the first prototype to fly with three Raptor engines and will need the ability to stop and start those engines in-flight to perform full-fidelity 20 km (~12.5 mi) launch and landing tests. Even just sustaining 330 bar for 10-100+ seconds without destroying the engine is likely several Raptor iterations away. Still, given SpaceX’s track record, all of those milestones are likely just a matter of time and perseverance.

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.
