SpaceX is halfway done building the world’s largest rocket booster

Published

on

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.

Bearing attachment points for four Raptor engines and unfinished cutouts for four more, the first Super Heavy thrust dome appears to be complete and awaiting its sleeve of steel rings. (NASASpaceflight – bocachicagal)

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 launches in India with Model Y, showing pricing will be biggest challenge

Tesla finally got its Model Y launched in India, but it will surely come at a price for consumers.

Tesla has officially launched in India following years of delays, as it brought its Model Y to the market for the first time on Tuesday.

However, the launch showed that pricing is going to be its biggest challenge. The all-electric Model Y is priced significantly higher than in other major markets in which Tesla operates.

On Tuesday, Tesla’s Model Y went up for sale for 59,89,000 rupees for the Rear-Wheel Drive configuration, while the Long Range Rear-Wheel Drive was priced at 67,89,000.

This equates to $69,686 for the RWD and $78,994 for the Long Range RWD, a substantial markup compared to what these cars sell for in the United States.

Deliveries are currently scheduled for the third quarter, and it will be interesting to see how many units they can sell in the market at this price point.

The price includes tariffs and additional fees that are applied by the Indian government, which has aimed to work with foreign automakers to come to terms on lower duties that increase vehicle cost.

There is a chance that these duties will be removed, which would create a more stable and affordable pricing model for Tesla in the future. President Trump and Indian Prime Minister Narendra Modi continue to iron out those details.

Maharashtra Chief Minister Devendra Fadnavis said to reporters outside the company’s new outlet in the region (via Reuters):

“In the future, we wish to see R&D and manufacturing done in India, and I am sure at an appropriate stage, Tesla will think about it.”

It appears to be eerily similar to the same “game of chicken” Tesla played with Indian government officials for the past few years. Tesla has always wanted to enter India, but was unable to do so due to these import duties.

India wanted Tesla to commit to building a Gigafactory in the country, but Tesla wanted to test demand first.

It seems this could be that demand test, and the duties are going to have a significant impact on what demand will actually be.

Tesla ups Robotaxi fare price to another comical figure with service area expansion

Tesla upped its fare price for a Robotaxi ride from $4.20 to, you guessed it, $6.90.

Tesla has upped its fare price for the Robotaxi platform in Austin for the first time since its launch on June 22. The increase came on the same day that Tesla expanded its Service Area for the Robotaxi ride-hailing service, offering rides to a broader portion of the city.

The price is up from $4.20, a figure that many Tesla fans will find amusing, considering CEO Elon Musk has used that number, as well as ’69,’ as a light-hearted attempt at comedy over the past several years.

Musk confirmed yesterday that Tesla would up the price per ride from that $4.20 point to $6.90. Are we really surprised that is what the company decided on, as the expansion of the Service Area also took effect on Monday?

The Service Area expansion was also somewhat of a joke too, especially considering the shape of the new region where the driverless service can travel.

I wrote yesterday about how it might be funny, but in reality, it is more of a message to competitors that Tesla can expand in Austin wherever it wants at any time.

Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors

It was only a matter of time before the Robotaxi platform would subject riders to a higher, flat fee for a ride. This is primarily due to two reasons: the size of the access program is increasing, and, more importantly, the service area is expanding in size.

Tesla has already surpassed Waymo in Austin in terms of its service area, which is roughly five square miles larger. Waymo launched driverless rides to the public back in March, while Tesla’s just became available to a small group in June. Tesla has already expanded it, allowing new members to hail a ride from a driverless Model Y nearly every day.

The Robotaxi app is also becoming more robust as Tesla is adding new features with updates. It has already been updated on two occasions, with the most recent improvements being rolled out yesterday.

Tesla Model Y and Model 3 dominate U.S. EV sales despite headwinds

Tesla’s two mainstream vehicles accounted for more than 40% of all EVs sold in the United States in Q2 2025.

Tesla’s Model Y and Model 3 remained the top-selling electric vehicles in the U.S. during Q2 2025, even as the broader EV market dipped 6.3% year-over-year. 

The Model Y logged 86,120 units sold, followed by the Model 3 at 48,803. This means that Tesla’s two mainstream vehicles accounted for 43% of all EVs sold in the United States during the second quarter, as per data from Cox Automotive.

Tesla leads amid tax credit uncertainty and a tough first half

Tesla’s performance in Q2 is notable given a series of hurdles earlier in the year. The company temporarily paused Model Y deliveries in Q1 as it transitioned to the production of the new Model Y, and its retail presence was hit by protests and vandalism tied to political backlash against CEO Elon Musk. The fallout carried into Q2, yet Tesla’s two mass-market vehicles still outsold the next eight EVs combined. 

Q2 marked just the third-ever YoY decline in quarterly EV sales, totaling 310,839 units. Electric vehicle sales, however, were still up 4.9% from Q1 and reached a record 607,089 units in the first half of 2025. Analysts also expect a surge in Q3 as buyers rush to qualify for federal EV tax credits before they expire on October 1, Cox Automotive noted in a post.

Legacy rivals gain ground, but Tesla holds its commanding lead

General Motors more than doubled its EV volume in the first half of 2025, selling over 78,000 units and boosting its EV market share to 12.9%. Chevrolet became the second-best-selling EV brand, pushing GM past Ford and Hyundai. Tesla, however, still retained a commanding 44.7% electric vehicle market share despite a 12% drop in in Q2 revenue, following a decline of almost 9% in Q1.

Incentives reached record highs in Q2, averaging 14.8% of transaction prices, roughly $8,500 per vehicle. As government support winds down, the used EV market is also gaining momentum, with over 100,000 used EVs sold in Q2.
