SpaceX first Super Heavy ‘test tank’ is almost ready for prime time
SpaceX has almost completed a ‘test tank’ meant to ensure that Starship’s Super Heavy booster is capable of withstanding the immense thrust of more than two-dozen Raptor engines.
Believed to be known as test tank BN2.1, the prototype’s latest appearance comes on the heels of news from CEO Elon Musk that SpaceX has upgraded Super Heavy with one extra Raptor engine – with plans to add another three down the road. The results of that tank’s imminent test campaign will likely be crucial as the company shifts its focus sending Starship to orbit (or close) as soon as possible.
Prior to a new Super Heavy booster ‘thrust puck’ design first spotted on May 29th, at least two separate booster engine section prototypes completed in the last few months sported an earlier variant more akin to a donut. At that point, Super Heavy’s design had a central cluster of eight gimballing, throttleable Raptors surrounded by a ring of 20 Raptor Boost (“RBoost”) engines – a variant meant to trade the ability to throttle for ~25% more thrust.

While Super Heavy booster BN1’s almost immediate scrapping – prior to a single test – guaranteed that major design changes were on the way, exactly what those changes would be was anyone’s guess. The appearance of a new booster ‘thrust puck’ design and Musk’s subsequent announcement that Super Heavy will “initially” have 29 – not 28 – Raptors likely mean that that engine section redesign was a major contributor to BN1’s instant obsolescence. The only other major change SpaceX clearly made with booster BN2 was switching the positions of its liquid methane and liquid oxygen tanks, ensuring that Super Heavy’s heavier oxidizer is closer to the rocket’s base.
Musk also stated that SpaceX will eventually upgrade Super Heavy to 32 engines, giving future boosters a central cluster of 12 engines that the SpaceX CEO says will significantly improve the efficiency of boostback burns.
With 29 identical Raptors, the simplest possible Super Heavy booster would produce up to 5800 tons (12.8M lbf) of thrust at liftoff. If SpaceX has already completed Raptor Boost’s design and qualification and kicked off mass production of a 250-mTf engine, that liftoff thrust climbs to 6800 tons (~15M lbf). If SpaceX achieves performance goals (~210 mTf stock; ~300 mTf RBoost) mentioned by Musk last year, a 32-engine Super Heavy could achieve peak liftoff thrust greater than 8500 metric tons (~18.7M lbf).
Even in its weakest configuration, Super Heavy will still be more than 60% more powerful than Saturn V and 25% more powerful than N1 – the largest rockets to have ever successfully or unsuccessfully flown. That immense thrust demands a structure capable of surviving those extreme forces while simultaneously feeding dozens of Raptors up to ~28 metric tons (~61,000 lb) of propellant every second and withstanding several thousand tons of liquid oxygen – all without leaking, cracking, or flexing too much.


While BN2.1 wont have any of the plumbing associated with dozens of Raptors, nine hydraulic rams will let SpaceX subject its Super Heavy thrust structure to the simulated thrust of some number of engines. Given the presence of nine rams and nine clustered engines, it’s unclear if BN2.1 will only test that main thrust structure or if those rams will somehow be spread out to simulate the thrust of a full 29 engines – 20 of which will instead transfer most or all of their thrust into Super Heavy’s skirt.
Regardless, if successful, BN2.1’s test campaign should leave SpaceX on track to attempt Starship’s inaugural spaceflight as early as Q3 2021. If issues arise, that target could easily slip to Q4 or into 2022, but SpaceX’s test tank campaigns have historically been very successful.

Tesla makes Elon Musk’s new compensation package official
This is an important thing to note, as much of the media coverage regarding Musk’s pay package seems to indicate that the company and the shareholders are simply giving the CEO the money. He has to come through on each of these tranches to unlock the $1 trillion.
Tesla has made CEO Elon Musk’s new compensation package official, as it filed a Form 4 with the Securities and Exchange Commission (SEC) on Monday.
The package officially gives Musk the opportunity to acquire over 423 million shares of Tesla stock (NASDAQ: TSLA), dependent on his ability to achieve twelve performance-based tranches that will bring growth to the company and its shareholders.
Tesla (TSLA) shareholders officially approve Elon Musk’s 2025 performance award
Musk’s new compensation package was approved by investors last Thursday at the company’s Annual Shareholder Meeting, as over 75 percent of voters supported the CEO’s new plan, which could be valued at over $1 trillion if he is able to come through on all twelve tranches.
The twelve tranches include growth goals related to vehicle deliveries, the Optimus humanoid robot project, and Tesla’s valuation. If Musk is able to achieve each tranche, he would help Tesla achieve an over $8 trillion market cap.
The 12 tranches include:
-
$2 trillion market cap + Deliver 20 million Tesla vehicles cumulatively
-
$2.5 trillion market cap + Reach 10 million active Full Self-Driving (FSD) subscriptions
-
$3 trillion market cap + Deliver 1 million Optimus humanoid robots
-
$3.5 trillion market cap + Operate 1 million Robotaxis commercially
-
$4 trillion market cap + Hit $50 billion in adjusted EBITDA (earnings before interest, taxes, etc.)
-
$4.5 trillion market cap + Hit $80 billion in adjusted EBITDA
-
$5 trillion market cap + Hit $130 billion in adjusted EBITDA
-
$5.5 trillion market cap + Hit $210 billion in adjusted EBITDA
-
$6 trillion market cap + Hit $300 billion in adjusted EBITDA
-
$6.5 trillion market cap + Hit $400 billion in adjusted EBITDA
-
$7.5 trillion market cap + Hit $400 billion in adjusted EBITDA for four straight quarters in a row
-
$8.5 trillion market cap + Hit $400 billion in adjusted EBITDA for four straight quarters in a row
Achieving the twelve levels of the new compensation package would also give Musk what he’s really after: a larger ownership share in Tesla, which would help him achieve more control, something he feels is necessary for the rollout of the Optimus robot “army.”
Musk does not earn a dime if he does not achieve any of the tranches above.
This is an important thing to note, as much of the media coverage regarding Musk’s pay package seems to indicate that the company and the shareholders are simply giving the CEO the money. He has to come through on each of these tranches to unlock the $1 trillion.

Tesla provides vehicles for German firefighters’ EV training program
The sessions were aimed at improving emergency services for accidents involving electric vehicles.
Firefighters from across Germany recently gathered at Tesla Gigafactory Berlin-Brandenburg to practice emergency procedures on electric vehicles. The first training session last weekend focused on dismantling Tesla vehicles using spreaders, shears, and saws, giving responders hands-on experience with modern EV construction and safety features.
The sessions were aimed at improving emergency services for accidents involving electric vehicles, which, while less likely to catch fire than conventional cars, require special handling.
Challenges for first responders
During the exercises, firefighters discovered that Tesla vehicles’ sturdy, unified body panels, which are among the reasons why they are among the safest cars on the road, made cutting doors and roofs more difficult than in older vehicles, as noted in an rbb24 report.
“It was a real eye-opener,” firefighter Martin Haschick said, adding that his first attempt showed him “how not to do it, because we are also trained on older vehicles, and that took longer than I expected.” Tesla trainers demonstrated proper techniques to safely dismantle vehicles, emphasizing differences between older combustion-engine cars and today’s EVs.
Patrick Fath, head of the Tesla plant fire brigade, explained that hands-on experience with current EVs is critical, as scrap cars typically used in training do not reflect modern material strengths or technological design.
“They naturally have a completely different level of technology and different material strengths. But what can happen to us in everyday life – on the highway, on the roads, involves modern vehicles,” Fath stated.
Future training programs
Tesla plans to continue offering training for regional fire departments and state fire service schools, with the Brandenburg Ministry of the Interior observing the initial sessions to provide feedback. Exercises currently avoid live fires or fluid leaks due to the factory’s location in a drinking water protection zone. Tesla covers the costs of these programs, aiming to enhance first responders’ knowledge of modern EV safety and accident procedures.
In a comment, Fath highlighted that electric vehicle fires should not be too much of a problem, considering that the vehicles don’t catch fire as often as their combustion-powered counterparts. “Studies and experience from recent years have already shown that electric vehicles catch fire far less often than conventional vehicles. We have far fewer flammable materials, no gasoline or diesel tank, and therefore fewer ignition sources,” Fath stated.
Authorities have announced similar conclusions. The German Insurance Association (GDV) has confirmed that EVs catch fire significantly less often than combustion-powered cars, with statistics showing that around 14,200 vehicles caught fire in Germany in 2023. At the time, no higher fire risk was found in EVs. Data from the US National Transportation Safety Board (NTSB) from 2024 also showed that about 25 out of 100,000 EVs catch fire, which is notably fewer than the 1,530 out of 100,000 combustion-powered vehicles that catch fire.

SpaceX’s next project will produce Starships at a level that sounds impossible
1,000 rockets per year is an insane number, especially considering Starship’s sheer size.
Elon Musk has revealed bold plans for SpaceX’s newest Starbase facility in Texas, predicting it will become a birthplace for “so many spaceships.” The upcoming “Gigabay,” a massive $250 million production hub in Starbase, Texas, is designed to manufacture up to 1,000 Starship rockets per year.
That’s an insane number of rockets for a single facility, especially considering Starship’s sheer size.
One of the world’s largest industrial structures
SpaceX’s Gigabay is expected to stand roughly 380 feet tall and enclose 46.5 million cubic feet of interior space, making it one of the largest industrial structures to date. The facility will feature 24 dedicated work cells for assembling and refurbishing Starship and Super Heavy vehicles, complete with heavy-duty cranes capable of lifting up to 400 U.S. tons, as noted in a Times of India report.
Construction crews have already placed four tower cranes on-site, with completion targeted for December 2026. Once operational, the Gigabay is expected to boost SpaceX’s launch cadence dramatically, as it would be able to build up to 1,000 reusable Starships per year, as noted in a report from the Dallas Express. Musk stated that the Gigabay will be “one of the biggest structures in the world” and hinted that it represents a major leap in Starbase’s evolution from test site to full-scale production hub.
A key step toward Mars and beyond
Starship is SpaceX’s heavy-lift rocket system, and it remains a key part of Elon Musk’s vision of a multiplanetary future. The vehicle can carry 100–150 tonnes to low Earth orbit and up to 250 tonnes in expendable mode. With several successful flights to date, including a perfect 11th test flight, the Starship program continues to refine its reusable launch system ahead of crewed lunar missions under NASA’s Artemis initiative.
Starship is unlike any other spacecraft that has been produced in the past. As per Elon Musk, Starship is a “planet-colonizer” class rocket, as the magnitude of such a task “makes other space transport task trivial.” Considering Starship’s capabilities, it could indeed become the spacecraft that makes a Moon or Mars base feasible.
