SpaceX begins installing new ‘Raptor 2’ engines on Super Heavy booster

Published

SpaceX has begun installing new ‘Raptor 2’ engines on Super Heavy Booster 7 after the prototype completed a range of tests and returned to the company’s South Texas ‘Starbase’ rocket factory.

Earlier this month, SpaceX transported Booster 7 (B7) in the opposite direction, returning the 67-meter (~220 ft) tall rocket to Starbase’s orbital launch site (OLS) for the second time after it was forced to head back to the factory for repairs. Repairs completed, SpaceX dove headfirst into the process of verifying that the booster had been returned to full health and immediately filled its tanks to the brim with at least 3000 tons (>6.5M lb) of liquid nitrogen and oxygen – better known as a cryogenic proof test.

Less than 48 hours after completing its first post-repair test, Booster 7 sailed through another full cryoproof test without losing a beat. On May 13th, two days later, SpaceX attached a crane to Super Heavy B7 and removed it from the orbital launch mount before rolling the rocket back to Starbase’s build site on May 14th. Without official confirmation, which is increasingly rare, it was impossible to determine the results of the testing with certainty, but the speed of the process and Booster 7’s rapid launch mount removal made the two most extreme outcomes the most likely.

A quick return to the build site could have been explained by a significant vehicle failure or a major issue with SpaceX’s repair job – no point in continuing to test a vehicle that can’t be fully tested. On the exact opposite hand, a near-perfect test campaign in which all objectives were more or less achieved without major hiccups could also explain the quick return. In general, the evidence was in favor of the more optimistic explanation. Had a major issue been uncovered during the first post-repair cryoproof, it’s difficult to imagine that SpaceX would have completed the exact same test – in full less than 48 hours later.

However, SpaceX moved an in-situ Raptor engine installation stand towards Booster 7 and the orbital launch mount shortly before testing restarted, hinting – for the moment – that the company wanted to begin installing Raptor engines immediately after cryoproof testing. But mid-way through testing, the stand was moved back to its storage area and Super Heavy was instead removed from the mount and returned to the factory, adding a little uncertainty.

Concerns were immediately assuaged on May 17th when SpaceX was spotted moving Raptor engines from a production tent to the ‘megabay’ assembly building containing Booster 7. While the location of the new bay makes it difficult to peek inside from public viewpoints, preventing direct confirmation, it’s very likely SpaceX has begun installing new Raptor 2 engines on Super Heavy B7.

Additionally, confirming some of the more optimistic speculation about SpaceX’s decision to move Booster 7 back to build site, two of the three Raptor engines spotted on May 17th were also labeled “E26” and “E28.” Unless SpaceX’s engine numbering conventions have changed, the labels identify the engines as three of 20 ‘Raptor Boost’ engines that will ultimately populate the outer ring of Super Heavy B7’s aft end. More importantly, the installation of any Raptor Boost 2 (RB2) engines likely indicates that SpaceX has decided to install a full set of 33 Raptors on the booster before kicking off static fire testing.

To limit risk, SpaceX could have begun test-firing Booster 7 with just 1-3 Raptor engines installed and gradually added more as confidence grew. Instead, SpaceX appears to have accepted the added risk of losing 33 brand-new Raptor 2 engines in one fell swoop in return for the possibility of a much faster test campaign. If there are no major surprises during static fire testing, in other words, Booster 7 could be ready for flight far more quickly if the process begins with all 33 engines already installed. Installing Booster 7’s Raptors, heat shield, and aerocovers will be easier back at the build site.

Doing it all at once should also help prevent Booster 7 from suffering Booster 4’s fate and wallowing, unfinished, for months without completing a single useful test. If the gamble works, the first stage of a two-stage Starship could be ready for an orbital launch attempt in just a few months. If the gamble fails and Booster 7 is damaged, destroyed, or otherwise unable to pass the necessary tests, SpaceX will simply move on to Booster 8 sooner than later, having wasted less time on a more cautious Booster 7 test campaign.

It’s unclear how long it will take SpaceX to install all 33 Raptors, construct a heat shield around those engines, and finish buttoning up the rest of Booster 7. In an adjacent assembly bay, SpaceX appears to have nearly finished assembling a similarly upgraded Starship – Ship 24 – that’s first in line to ride Booster 7 into space. The company has also tentatively requested road closures for three 12-hour test windows on May 23rd, 24th, and 25th that either vehicle could use.

Tesla FSD ruins other intelligent driving systems for NIO Superfan influencer

“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands,” Lee wrote.

Tesla Full Self-Driving (FSD) has been making waves in China, with owners pushing the system to its limits on what appears to be a regular basis. Videos of Tesla drivers in China show FSD navigating the trickiest of roads, from busy city streets to narrow, unpaved paths in rural areas.

And as per an influencer and NIO superfan, FSD is ruining other driver-assist systems from other automakers in China.

FSD Ruins It For Influencer

China-based influencer and NIO superfan Andy Lee recently shared his thoughts about FSD on social media. As per Lee, Chinese intelligent driving systems are overhyped by marketing. But once he personally experienced FSD’s capabilities, he became disillusioned with the offerings of domestic carmakers.

“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands. I once thought that the ‘driving assistance’ of domestic brands could beat FSD in seconds, but it seems that I was wrong. Not only did they fail to outperform FSD, they were actually crushed in reverse,” Lee wrote in his post.

FSD could very well become Tesla’s moat since even cars that are equipped with the same hardware would not be able to perform similarly unless they have access to the company’s training data and software. Tesla’s fleet is ever-growing as well, which means that FSD will only get better over the years.

Unsupervised on the Horizon

Tesla is already using FSD Unsupervised for its vehicles that are produced in the Fremont Factory and Gigafactory Texas. As per Elon Musk during the Q1 2025 earnings call, he expects Tesla to be able to roll out FSD Unsupervised to consumers before the end of this year. He also highlighted that Tesla is being extremely careful with FSD Unsupervised’s rollout.

“Before the end of this year. Not necessarily — I say within the U.S., like we do want to test — at Tesla, we’re absolutely hardcore about safety. We go to great lengths to make the safest car in the world and have the lowest accidents per mile in. 

“So we want to be very careful. We want autonomy to be definitively safer than manual driving. So it’s not enough that it just be as safe. It needs to be meaningfully safer than if the car’s manually driven,” Musk stated.

During its Q1 2025 earnings call, Tesla executives hinted at the much-rumored “Model 2” and other next-gen EV designs.

Tesla slightly addressed whether or not it will be pushing forward with the debut of new models later this year in its latest earnings call. The company’s product development executive, Lars Moravy, shared some details about Tesla’s design process and the upcoming affordable models.

“We’re still planning to release models this year. As with all launches, we’re working through, like, the last minute issues that pop up. We’re knocking them down one by one. At this point, I would say that the ramp might be a little slower than we had hoped initially…But there’s nothing that’s blocking us from starting production within the next, within the timeline laid out in the opening remarks.

“And I will say it’s important to emphasize that, as we’ve said all along, the full utilization of our factories is the primary goal for these new products. And so the flexibility of what we can do within the form factor and, you know, the design of it is really limited to what we can do on our existing lines rather than building new ones. But we’ve been targeting the low cost of ownership. Monthly payment is the biggest differentiator for our vehicles, and that’s why we’re focused on bringing these new models with the, you know, the lowest price, to the market, within the constraints I just highlighted.”

In January, Tesla’s Chief Financial Officer Vaibhav Taneja teased several new product introductions for this year. There is at least one product that most Tesla supporters and investors are hoping to see: the company’s affordable vehicles, which have been dubbed by the EV community as the “Model 2” or “Model Q.”

Before Tesla’s Robotaxi event last year, many speculated that the company would also unveil its affordable next-gen vehicle. Gene Munster from Deepwater had expected Tesla to release a stripped-down version of the Model 3 as its affordable vehicle during the Robotaxi event. In the end, Tesla unveiled its Robotaxi vehicle and its Robovan design.

It’s been a while since the Robotaxi event, and Tesla has kept mum about its affordable vehicle. Considering its Q1 2025 performance, TSLA investors look forward to catalysts that could boost the stock.

The “Model 2” has been labeled a potential catalyst for Tesla. As such, TSLA investors and supporters have been itching for news about the new affordable vehicle. The main questions surrounding the “Model 2” revolve around its design and price. Based on Moravy’s statement, the “Model 2’s” design will heavily depend on Tesla’s current assembly lines and supply chain structures.

A TSLA investor has decided to stand her ground after receiving a threatening, Nazi-themed card at her home.

The Tesla investor even welcomed a new Ultra Red Tesla Model Y to show her support for the company.

Responding with a New Tesla

As per 58-year-old Alexandra Merz, an investment analyst and immigration consultant who immigrated from Germany to the United States, she received mail from a Boston address to her home on April 17. Upon opening the letter, she was greeted by an image of the Tesla logo incorporated with a Nazi salute.

Inside the card was a handwritten message which read, “History has its eyes on you.” Merz promptly reported the message to the FBI. In a comment to the New York Post, she stated that she is now even more motivated to support Elon Musk and his ventures.

“This atrocious behavior motivates me even more to stand up for Tesla, Elon, and DOGE,” Merz noted. “I bought our fifth Tesla last Saturday, a beautiful red Model Y, the best car out there. And it drives itself.”

An Unfortunate Trend

In previous comments, Merz expressed her disdain for the ongoing attacks against Tesla and Musk. “Tesla is employing more than 140,000 employees worldwide, building the most American cars in the U.S., and building the European Model Ys in Berlin. I often wonder whether these protesters have thought through what they are doing,” she stated.

Elon Musk himself admitted to the disturbing trend during Tesla’s Q1 2025 earnings call, stating that “there’s been some blowback for the time that I’ve been spending in government with the Department of Government Efficiency or DOGE.” The CEO also stated that he would soon be stepping back from DOGE’s everyday operations and focusing more of his time on Tesla.

U.S. President Donald Trump also addressed the ongoing attacks on Teslas in a comment about Musk’s impeding step back from DOGE. As per Trump, people against Musk are taking out their frustrations on Tesla and its owners, which is unfair. He also described the people behind the attacks on Tesla as “sick.”
