SpaceX's Elon Musk reveals next Starship's Raptor engines, explains latest failure
SpaceX CEO Elon Musk took to Twitter to better explain what happened when the latest full-scale Starship prototype failed during one of its first tests, while later revealing the rocket engines set to power a future prototype’s first flight.
On April 3rd, SpaceX initiated the third full-scale Starship prototype’s first cryogenic (ultra-cold) pressure test by loading the ~30m (100 ft) tall rocket’s upper propellant tank with what was likely 400+ metric tons (~900,000 lb) of liquid nitrogen. For several hours, liquid nitrogen – a chemically-neutral propellant simulant – was loaded and offloaded several times. Finally, around 2:07 am local (07:07 UTC), the liquid oxygen tank below the methane tank abruptly crumpled, reminiscent of a plastic bottle with the air partially sucked out of it. After several long seconds of gradual crumpling, gravity did what gravity does and pulled the heavy upper tank to the ground, shredding the rest of the rocket’s thin steel skin.
Both unfortunate and a positive development, Musk has recently confirmed Teslarati’s earlier speculation that based on videos of the anomaly, a bad test design and operator error(s) – rather than a technical fault of the rocket itself – could have been the cause of Starship SN3’s failure. In other words, barring future operator error-related failures, Starship SN3’s second cryogenic test went quite well and should mean no delays to Starship SN4’s ongoing assembly.
Particularly in light of Elon Musk’s statement that operator error and a bad test design caused Starship SN3’s failure, the ship’s April 3rd performance was quite impressive. That SN3 remained vertical for several seconds after its aft tank crumpled and likely lost pressure – despite carrying a load equivalent to a fully-loaded Boeing 747 passenger jet – suggests that the vehicle’s structure is extremely robust.
In his explanation, Musk revealed that the rocket failed because the lower (liquid oxygen) tank had not been pressurized enough to withstand the stress of a methane tank fully loaded with liquid nitrogen. Musk’s description almost makes it sound like one or several people failed to account for the fact that liquid nitrogen is nearly 25% heavier than the cryogenic methane it was simulating.
Thankfully, while a prototype likely worth several million dollars and at least a month of work was lost, that means that SpaceX should be able to move on to SN4 with confidence – at least as long as it can rectify whatever allowed those operator mistakes to occur.
In the same Twitter session, Musk – presumably burning the late-night oil at SpaceX’s Boca Chica, Texas Starship factory – also posted a photo showing three operational Raptors in the same frame, a definite first for the cutting-edge rocket engine. Had Starship SN3 survived its cryogenic proof tests last week, SpaceX’s plan was to install and static fire either one or three Raptor engines. A successful static fire campaign would have then been followed soon after by a full-scale Starship’s inaugural flight test, potentially seeing the ship fly as high as Starhopper’s final August 2019 hop.
Now, while Musk says SpaceX may still “reuse much of [SN3’s] thrust section,” the company’s Starship test plan will now rely on SN4 – the next full-scale prototype. It’s far more likely that SN4 will reuse almost no structural aspects of SN3, but even that might cause just a few weeks of delays. Based on a particular assembly step completed on April 4th, Starship SN4 is only four weeks away from the launch pad under the assumption of zero improvements to the speed of production, assembly, and outfitting. Knowing SpaceX, SN4 could be fully stacked and outfitted even sooner.
For now, it looks like we’ll thus have to wait at least a few more weeks to see Starship attempt another cryogenic proof test and – potentially – breathe its first fire with one or several Raptor engines.

Tesla Giga Berlin makes big move amid strong sales and demand
“We currently have very good sales figures and have therefore revised our production plans for the third and fourth quarters upwards.”

Tesla is making a big move at its factory in Germany, known as Giga Berlin, as managers at the plant have indicated the company plans to increase its production rate for the remainder of the year.
Giga Berlin is responsible for manufacturing Model Y vehicles for several markets worldwide, including those outside of Europe. It was opened in March 2022, and it recently built its 500,000th Model Y in March and its 100,000th new Model Y just three weeks ago.
Due to some encouraging sales figures in the markets it provides vehicles for, Tesla said it is planning to increase production at the factory for the remainder of the year.
Andrè Thierig, plant manager at Giga Berlin, said to German news outlet DPA on Sunday that market data has encouraged a move to be made regarding the production at the factory:
“We currently have very good sales figures and have therefore revised our production plans for the third and fourth quarters upwards.”
It is interesting to see this kind of narrative from Thierig, especially as data has shown Tesla has struggled in various markets, including Germany, this year.
Sales drops have been reported, but other markets are holding strong, especially those in Northern Europe, such as Norway, where the Model Y saw a nearly 39 percent increase in sales in August compared to the same month the previous year.
Gigafactory Berlin supplies vehicles for other markets, such as Canada, Australia, and New Zealand, which are strategically important to avoid tariffs. It also builds cars for the Middle East.
Thierig reiterated this point during the interview with DPA:
“We supply well over 30 markets and definitely see a positive trend there.”

Tesla analyst says Musk stock buy should send this signal to investors
“With Musk’s (Tesla stock) purchase, combined with the upward momentum for delivery expectations and robotaxi rollout, we are becoming more bullish.”

Tesla CEO Elon Musk purchased roughly $1 billion in Tesla shares on Friday, and analysts are now breaking down the move as the stock is headed upward.
One of them is William Blair analyst Jed Dorsheimer, who said in a new note to investors on Monday that Musk’s move should send a signal of confidence to stock buyers, especially considering the company’s numerous catalysts that currently exist.
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
Dorsheimer said in the note:
“With Musk’s (Tesla stock) purchase, combined with the upward momentum for delivery expectations and robotaxi rollout, we are becoming more bullish. This purchase is Musk’s first buy since 2020. To us, this sends a strong signal of confidence in the most important part of Tesla’s future business, robotaxi.”
Musk putting an additional $1 billion back into the company in the form of more stock ownership is obviously a huge vote of confidence.
He knows more than anyone about the progress Tesla has made and is making on the Robotaxi platform, as well as the company’s ongoing efforts to solve vehicle autonomy. If he’s buying stock, it is more than likely a good sign.
Tesla has continued to expand its Robotaxi platform in a number of ways. The project has gotten bigger in terms of service area, vehicle fleet, and testing population. Tesla has also recently received a permit to test in Nevada, unlocking the potential to expand into a brand-new state for the company.
In the note, Dorsheimer also touched on Musk’s recent pay package, revealing that William Blair recently met with Tesla’s Board of Directors, who gave the firm some more color on the situation:
“We recently participated in a meeting with Tesla’s board of directors to discuss the details of Musk’s performance package. The board is confident of its position in the Delaware case and anticipates a verdict by end of year. It does not expect a similar situation to occur under new Texas jurisdiction. Musk has the board’s full support, and we expect he’ll get more than enough shareholder support for this to pass with flying colors.”
Tesla stock is up over 6 percent so far today, trading at $421.50 at the time of publication.

Morgan Stanley’s Adam Jonas dubs Tesla FSD a “game changer” after marathon drive
Jonas reported that FSD handled more than 99% of the miles.

Morgan Stanley’s analyst Adam Jonas shared a notable endorsement of Tesla’s Full Self-Driving (FSD) software after completing a 1,400-mile round trip from New York to Michigan in his Model Y.
Jonas reported that FSD handled more than 99% of the miles, calling the system “a game changer” for long-distance driving.
Hands-free experience
Jonas drove his 2021 Tesla Model Y equipped with Hardware 3 and FSD Supervised v12.6.4, and he used the system nearly the entire trip. “Having your hands off the wheel and feet off the pedals for nearly 12 hours of driving is a real game changer that is hard to appreciate without experiencing it for yourself,” he noted.
He explained that outside of two heavy downpours, one on the Pennsylvania Turnpike and another in suburban Detroit, plus some light maneuvering in fast food parking lots, FSD handled the drive without any human intervention. “FSD made no mistakes or close calls that I recall. The system handles highways very safely and confidently. I cannot imagine buying another EV without FSD.”
Broader implications
Jonas added that he has used FSD consistently over the past 18 months, and the $8,000 he paid for the feature feels like a bargain considering the value. He also praised Tesla’s Supercharging network, which supported his trip without issue.
Jonas has been one of Wall Street’s most closely followed voices on Tesla, and his comments add weight to the ongoing debate about the role of autonomy in the company’s future. His current price target for Tesla stock stands at $410. During Morgan Stanley’s 13th Annual Laguna Conference, he echoed similar experiences with Tesla’s software, emphasizing that FSD “probably drove well over 99% of the miles” on his recent trips.
