SpaceX CEO Elon Musk reveals the heart of Starship’s Super Heavy booster

CEO Elon Musk has revealed the first glimpse of the most complex, important, and unproven part of Starship’s record-breaking Super Heavy booster.

Known as the engine section, the aft end of Super Heavy is likely where the fate of early booster prototypes will lie. For the most part, Super Heavy is just a colossal duo of steel propellant tanks that is – to an extent – even simpler than its smaller Starship upper stage, which needs two types of Raptor engines, flaps, a bevy of maneuvering thrusters, and more. However, at the booster’s base, SpaceX must design, fabricate, and assemble a nightmarishly crowded and complex mechanical structure capable of mounting, fueling, and powering anywhere from 29 to 33 Raptor engines.

Simultaneously, that structure and all associated plumbing must withstand the force and pressure of more than 2000 metric tons of cryogenic liquid oxygen and the 7500 tons (16.5 million lbf) of thrust those Raptors can generate. That’s just the bare minimum, though.

Beyond the extraordinary mechanical stress it must withstand, Super Heavy’s thrust section also needs to be able to survive the hellish, violent environment created by almost three dozen powerful rocket engines on one side while the structure is effectively half-submerged in a cryogenic fluid, subjecting the puck and dome to brutal thermal conditions. Last but certainly not least, the exterior of Super Heavy’s thrust structure must be able to survive the mechanical and thermal hell of hypersonic atmospheric reentry with zero cushioning of the blow.

The forces involved are difficult to imagine. At full thrust, Super Heavy Booster 4’s 29 Raptor engines (eventually expanding to 33 on future cores) will likely produce more than 5500 metric tons (12.1 million lbf) of thrust, making it both the largest and most powerful rocket booster ever built or tested. At full thrust, those 29 Raptors will consume more than 17 metric tons (~38,000 lb) of cryogenic liquid methane and oxygen – equivalent to around ten Tesla Model 3s worth of propellant – every single second.

Including smaller secondary runs for each Raptor engine, Super Heavy’s engine section will likely contain miles of plumbing for highly flammable, explosive, and high-pressure liquid and gaseous methane and oxygen. All 29 Raptors also need to be connected to Super Heavy’s power supplies and avionics systems, demanding still more miles of wiring.

Ultimately, Musk says that the next generation of Starship’s Raptor engine – “V2.0” – “is a major improvement in simplification,” presumably making life a bit easier for the engineers that have to design Super Heavy’s hellish engine section plumbing and the technicians that have to fabricate and assemble it. However, there’s just no getting around the fact that a single rocket booster with dozens of engines is going to have an extraordinarily complex thrust section. Only time will tell if SpaceX’s extensive launch vehicle expertise is up to the task.

Tesla schedules Roadster unveiling event, and you won’t believe when it is

Published

Tesla has tentatively scheduled its unveiling event for the Roadster’s next-generation iteration, and you will not believe the date the company picked for it.

Tesla CEO Elon Musk said during the 2025 Annual Shareholders Meeting that the company is aiming for an April 1 demo event.

Yes, April Fools’ Day.

Tesla originally aimed for its “most epic demo” to take place at the end of this year. However, the writing on the wall as 2025 winds down seemed to indicate the company was not quite ready to show off everything it plans to implement into the Roadster.

Its capabilities have been teased quite heavily throughout most of the year, but the biggest hints came last week when Musk appeared on the Joe Rogan Experience Podcast.

He said:

“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveil ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”

The Roadster has been somewhat of a letdown, at least in its newest version, thus far. Tesla has routinely delayed the project, putting those who put lofty down payments on the car in a weird limbo, lost at what to do.

One notable pre-orderer cancelled his reservation last week and got in a spat with Musk about it.

Now that there is a definitive date for the Roadster unveiling, Musk and Co. should have a more definitive cutoff date for features and capabilities. Chief Designer Franz von Holzhausen said earlier this year that when they showed Musk what they had done with the Roadster, the CEO encouraged them to do even more with it.

This delayed things further.

Musk also said he believes production would begin between 12 and 18 months after the unveiling, putting it out sometime in 2027.

Tesla (NASDAQ:TSLA) CEO Elon Musk has officially approved his 2025 Performance Award, a landmark pay package that could make him the world’s first trillionaire and make Tesla the most valuable company in the world by a mile. 

The 2025 CEO Performance Award was officially approved by Tesla shareholders at the 2025 Annual Shareholder Meeting.

Elon Musk‘s landmark pay package

As per Tesla, more than 75% of the shareholders approved Elon Musk’s 2025 CEO Performance Award. It was then unsurprising that the approval of Elon Musk’s pay plan received overwhelming applause from the event’s attendees.

The CEO took to the stage with much enthusiasm, welcoming every shareholder to the event and dancing briefly on stage. Optimus also danced on stage smoothly, demonstrating its improved movements to much appause.

Elon Musk’s 10-year targets

To earn his 2025 CEO Performance Award, Musk would be required to grow Tesla’s market capitalization from about $1.1 trillion today to $8.5 trillion over the next decade. At that level, Tesla would surpass every major public company in existence. The compensation plan also requires Tesla’s operating profit to grow from $17 billion last year to $400 billion annually.

Apart from leading Tesla to become the world’s biggest company in history, Musk is also required to hit several product targets for the electric vehicle maker. These include the delivery of 20 million Tesla vehicles cumulatively, 10 million active FSD subscriptions, 1 million Tesla bots delivered, and 1 million Robotaxis in operation.

Tesla 2025 Annual Shareholder Meeting: How to watch

Published

The 2025 Tesla Annual Shareholder Meeting from Gigafactory Texas is set to kick off at 4 p.m. EDT, 3 p.m. CDT.

The company will be having its typical presentation for the event, where CEO Elon Musk, along with other executives will discuss things like future products, the outlook of its self-driving development, potential releases for next year, and some current events within the company.

However, this year’s Shareholder Meeting has slightly more implications than others, as Investors and Shareholders have spent the last several months petitioning and supporting one of the proposals on the docket that could be the deciding factor in Musk staying or leaving Tesla.

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

Proposal four outlines a new compensation package for Musk that could give him $1 trillion in shares if he is able to complete a variety of lofty goals related to production, self-driving, and other important company projects.

Musk has said that he is truly after more influence on company decisions, especially as the Tesla Optimus program is ramping up and becoming a more relevant part of the company’s story.

The CEO said during the Q3 Earnings Call that he would not feel comfortable developing an “army of robots” if he did not have a comfortable amount of influence in some of the decisions. He could be voted our or out-influenced by what he calls “activist shareholders.”

One of those investors came after his past pay package, which was approved by shareholders not once, but twice. Musk still was not able to obtain the pay because of a Delaware Chancery Court ruling.

Nevertheless, this is one of the last ditch efforts Tesla is making to get Musk the compensation that he wants.

The meeting is set to kick off at 3 p.m. local time in Austin. You can watch it via the livestream on X:
