SpaceX is halfway done building the world’s largest rocket booster
New photos of the SpaceX Starship program’s first Super Heavy confirm that the booster prototype – known as Booster Number 1 (BN1) and set to become the largest rocket booster ever built – is already halfway complete.
Set to be the world’s tallest, heaviest, and most powerful liquid rocket booster ever built, Super Heavy is expected to measure some 70 meters (~230 ft) tip to tail, weigh ~3700 metric tons fully fueled, and produce around 7500 metric tons (16.5 million lbf) of thrust at liftoff. Starship, the reusable upper stage and spacecraft SpaceX is busy prototyping and testing, is 40% shorter than Super Heavy and features less than a quarter as many Raptor engines, producing thrust roughly equivalent to Falcon 9’s first stage.
Super Heavy will be equivalent to almost ten Falcon 9s at full thrust and outclass every rocket ever built. However, the basic design of the booster is effectively the same as any other liquid-fueled rocket, opting for a tall and thin Falcon-style cylinder with a high aspect ratio and no exterior coating – just bare metal.
Super Heavy’s airframe is made up of two main propellant tanks joined by a “common dome” and capped at both ends with an interstage (the structure that mates the booster to Starship) and engine/skirt section (encloses the thrust dome, supports landing legs, and houses umbilical ports).
While Super Heavy is dramatically different from Starship by almost any measure, SpaceX has ensured that hardware commonality is as extensive as possible. Ultimately, with minor tweaks, that means that SpaceX can (in theory) build Super Heavy with the exact same tools and techniques it’s used to churn out Starship prototypes.
As of the end of this month, a flurry of public photos from local (and visiting) photographers have confirmed that Super Heavy booster BN1 is effectively halfway to completion and currently stands 18 steel rings tall. Aside from booster-specific layout changes, that 33-meter-tall (~105 ft) barrel section is virtually identical to a Starship’s 20-ring barrel section, lacking only conical nose section that caps them off.
The 18-ring stack also guarantees that the current assembly is Super Heavy BN1’s liquid oxygen (LOx) tank and confirms that like ITS, BFR, Falcon 9, and other SpaceX rockets, Super Heavy’s LOx tank will sit above its fuel (methane) tank. Likely either 38 or 39 rings tall overall, it also indicates that BN1 is a ring away from half of its full height, leaving the integration of its strengthened methane tank, custom engine section, and skirt as the last major tasks standing between SpaceX and its first Super Heavy prototype.
According to Elon Musk, SpaceX will likely hop BN1 if or when it passes initial cryogenic proof and static fire testing. If that goes according to plan, it’s unclear if BN1 can be converted for two-stage Starship launch attempts or if SpaceX will simply move on to BN2 (already under construction).

Tesla engineer explains why Elon Musk deserves new pay package
“When Elon is motivated, it also motivates us, especially in this fork of humanity. I would not be staying in Tesla this long unless he is still leading.”

A Tesla engineer took to X to explain why he believes Elon Musk deserved the new 96 million share, $29 billion pay package that the company awarded to him yesterday.
Yun-Ta Tsai, a Senior Staff Engineer in the Autopilot program at Tesla, has worked at the company for five years. He has been in his current position for two years and three months.
Tesla rewards CEO Elon Musk with massive, restricted stock package
Tsai posted a lengthy statement in response to Tesla announcing its new pay package for Musk, which the company’s Board of Directors announced yesterday. He was fully in support of his boss getting paid, especially considering Musk “came to work every day” without being paid for eight years.
Tsai said:
“8 years without pay, but Elon still came to work everyday despite hitting all the milestones.
Most founders, even being paid much better, would simply abandon ships or being “zucked”.
I often joked my annual comp was higher than Elon but it was true.
When Elon is motivated, it also motivates us, especially in this fork of humanity. I would not be staying in Tesla this long unless he is still leading.
Hopefully Elon gets his first paycheck soon after 8 years of grinding in hell. It is time.”
It’s no secret that Musk has the reputation of someone who is incredibly driven, motivated, and determined to come through on his personal and professional goals. In times of need at the company, Musk sleeps at the office and works seven days a week.
Recently, it came to the surface that he nearly missed his brother’s wedding years ago because of work.

Musk’s attitude toward work is what has made Tesla, SpaceX, Neuralink, and other entities so successful.
Musk’s new pay package
Tesla announced the new pay package for Musk yesterday, under the following terms:
- 96 million restricted shares of stock, subject to Elon paying a purchase price upon meeting a two-year vesting term, to be delivered after receipt of antitrust regulatory approval
- The purchase price will be equal to the split-adjusted exercise price of the stock options awarded to Elon under the 2018 CEO Performance Award ($23.34 per share)
- A requirement that Elon serve continuously in a senior leadership role at Tesla during the two-year vesting term
- A pledging allowance to cover tax payments or the purchase price
- A mandatory holding period of five years from the grant date, except to cover tax payments or the purchase price (with any sales for such purposes to be conducted through an orderly disposition in coordination with Tesla); and
- If the Delaware courts fully reinstate the 2018 CEO Performance Award, this interim award will be forfeited or returned or a portion of the 2018 CEO Performance Award will be forfeited. To put it simply, there cannot be any “double dip.” Elon will not be able to keep this new award in addition to the options he will be awarded under the 2018 CEO Performance Award, should the courts rule in our favor
The board added a statement that said it believed now would be an ideal time “to take decisive action to recognize the extraordinary value that Elon created for Tesla shareholders.”

Tesla Cybertruck leftovers are the main course at the Supercharger Diner
Tesla is using recycled steel from Cybertruck manufacturing for the Supercharger Diner in Los Angeles.

Tesla Cybertruck panels that are leftover from manufacturing became the main course at the Supercharger Diner, contributing to the futuristic restaurant’s unique exterior design.
The Supercharger Diner was an idea of Tesla CEO Elon Musk’s in 2018, and in July 2025, it officially opened for business, serving a variety of interesting dishes in a futuristic setting that pays homage to the 1950s restaurant experience.
The design of the Diner is what truly sets it apart: it is reminiscent of the stainless exterior that Tesla used for the Cybertruck. It turns out that’s exactly what it is.

Tesla Chief Designer Franz von Holzhausen revealed in an interview with Tesla Owners Club Austria that the company used recycled panels from Cybertruck manufacturing as siding on the epic diner.
Here’s what he said:
Tesla Diner was inspired by the Jetson‘s and was built with steel from @cybertruck production 🛸 pic.twitter.com/3t4038RY4H

Tesla sourced its stainless steel for the exoskeleton of the Cybertruck from Steel Dynamics Inc. and its plant in Sinton, Texas. The company confirmed this through various outlets, including exhibit descriptions at the Petersen Automotive Museum. The steel is refined through a third party before it is used.

It also uses the same steel for SpaceX Starship.
It’s pretty interesting that Tesla chose to use the stainless steel for the exterior of the diner in Los Angeles, but it also makes sense considering how durable it has proven to be.

Tesla ‘activist shareholders’ sue company and Elon Musk for Robotaxi rollout
Tesla’s activist shareholders are coming after the company, claiming it misled investors about the Robotaxi rollout.

Tesla’s “activist shareholders” seem to be one of the biggest threats to the company and its CEO, Elon Musk, who has spoken extensively about them in recent times. They’re up to their latest bit of work against the company, suing both Tesla and Musk, accusing them of securities fraud by alleging they concealed “significant risk” over the Robotaxi launch in Austin, Texas.
On Monday night, a group of shareholders sued Tesla and Musk in a proposed class action lawsuit in Texas federal court. They claim Tesla misled investors about the safety of the vehicles used in the Robotaxi rollout in Austin, which started on June 22.
The suit indicates that videos show the vehicles “speeding, exhibiting sudden braking, driving over a curb, entering the wrong lane, and dropping passengers off in the middle of multilane roads.” Reuters first reported on the lawsuit.
The plaintiffs are seeking damages for shareholders between April 19, 2023, and June 22, 2025.
Tesla’s Robotaxi platform has been operating for less than two months, and the company has already expanded its geofence in Austin twice.
🚨 Tesla Austin Robotaxi geofence sizes (in square miles):
Initial: 6/22 – ~20 square miles
First Expansion: 7/14 – ~42 square miles
Second Expansion: 8/3 – ~80 square miles pic.twitter.com/IwnvSJseE4

In the roughly six weeks that Robotaxi has been operational, Tesla has only had one incident reported to the Austin Government, and it was a “Safety Concern” in June 2025. Since July 2023, which is when autonomous vehicle operation began in Austin, 130 incidents have been reported. AV Ride, Cruise, Waymo, and Zoox also operate in Austin.
Waymo has the most incidents with 73. Its first was in June 2024 when a unit blocked traffic.
Activist Shareholders
Musk has warned that activist shareholders are potentially dangerous to both Tesla and his position as CEO. He recently spoke about them during the Q2 Earnings Call regarding his stake in the company:
“That is a major concern for me, as I’ve mentioned in the past. I hope that is addressed at the upcoming shareholders meeting. But, yeah, it is a big deal. I want to find that I’ve got so little control that I can easily be ousted by activist shareholders after having built this army of humanoid robots. I think my control over Tesla, Inc. should be enough to ensure that it goes in a good direction, but not so much control that I can’t be thrown out if I go crazy.”
Tesla’s Board yesterday made an attempt to help secure Musk’s stake by offering him a massive 96 million share pay package of restricted stock. It will only help his stake in the company bump up slightly to 14.6 percent from 12.9 percent.
