SpaceX Starship prototype ready for record-breaking tests

Published

on

Over the weekend, SpaceX has installed the last of its first orbital-class Starship’s six Raptor engines, setting the prototype up for one or several record-breaking tests later this week.

Tentatively scheduled as early as 10am to 6pm CDT on Monday Tuesday, November 1st 2nd, the next test up on Starship 20’s (S20) docket will likely be its third static fire in eleven days. Ship 20 completed its first Raptor-involved test – known as a preburner test – on October 19th, followed by two successful back-to-back static fires – one with one Raptor and one with two – on October 21st.

Less than 36 hours later, the Starship’s two missing Raptor Center (RC) engines (of a total of three) had been installed by Friday morning, October 22nd. For unknown reasons, no testing was completed the following week it and it took SpaceX another six and a half days to deliver the final two missing engines to the pad for installation on S20. Regardless, both missing Raptor Vacuum engines were installed by 2am CDT on Saturday, October 30th, marking the second time a Starship prototype has had all six Raptors installed.

While it might be the second time SpaceX has installed six Raptors on a Starship, it’s likely the first time six engines have been fully integrated with Ship 20’s propellant tanks, gas supplies, and avionics. How exactly SpaceX plans to proceed is unclear but odds are good that Starship S20’s next static fire test campaign will involve simultaneous igniting at least four of its six Raptor engines, setting a new record for the number of Raptors simultaneously ignited.

More likely than not, though, Ship 20’s next campaign will culminate in the simultaneous ignition of all six Raptors to (hopefully) complete the first true orbital-class Starship static fire. Like SpaceX has only just begun to do with Falcon boosters, flight-proven Starships might eventually be able to skip preflight static fire tests, but it’s virtually guaranteed that SpaceX will still proof test Starship and Super Heavy before flights until ships, boosters, and Raptors have stable designs with substantial flight experience. To ensure full-fidelity testing, those static fires will always have to qualify all installed engines. That includes Starship, which is designed to burn both its sea-level and vacuum-optimized Raptors from booster separation to orbit.

At full throttle, depending on the efficiency of its three RVacs at sea level, Starship S20’s six Raptor V1.0 engines could produce ~1100 tons (~2.4M lbf) of thrust. By comparison, SpaceX’s workhorse Falcon 9 rocket produces around 760 tons (~1.7M lbf) of thrust at liftoff, meaning that Starship will likely become the most powerful single-core rocket the company has ever tested even if it never throttles above ~70%.

There’s a good chance that SpaceX will start Ship 20’s next round of tests by separately firing both sets of three Raptor Center and Vacuum engines or with a mixed three or four-engine test to follow the latest two-engine test. SpaceX could also take the most iterative approach and test three, four, and five engines at a time before the final six-engine test. Regardless, virtually all possible static fire tests Ship 20 is now configured to perform will be program ‘firsts’ of some kind.

Tesla’s Supercharger network is proving to be a key factor in the company’s dominance in several key markets. These include Norway, which has become a place of strength for the new Model Y. 

This was hinted at by Tesla’s Director of Charging, Max de Zegher, on social media platform X.

Supercharger network sets the industry standard

As noted by the Tesla executive, the Model Y accounted for 29% of all vehicle sales in Norway in September. Part of the vehicle’s success was likely due to the reliability of the Supercharger Network, which is class leading even in Norway, where 98% of new cars sold are electric.

De Zegher emphasized on X that Tesla Superchargers are still in a class of their own. An EPSI survey of nearly 1,500 Norwegian EV drivers supported his claim, as Tesla Superchargers retained first place in customer satisfaction for the fifth consecutive year. 

The EPSI Survey‘s results

Respondents to the EPSI survey praised the Supercharger network’s strong uptime, abundant capacity, and user-friendly digital solutions, placing it ahead of other operators such as Uno-X. Survey researchers highlighted that Tesla has set the standard when it comes to simplicity in the charging process.

Drivers also cited competitive pricing and seamless plug-and-charge functionality as major reasons they prefer Tesla’s network, especially in Norway’s extreme winter conditions where reliability is critical.

“Tesla has set the standard for simplicity in the charging process. Combined with competitive prices, this means that many electric car drivers say they are likely to choose Tesla again the next time they need to charge,” EPSI noted in a post.

Tesla Senior Vice President for Automotive Tom Zhu, a key executive behind the company’s success in China and Giga Texas, recently highlighted the “prime directive” of Full Self-Driving (FSD).

Zhu’s comments emphasize Tesla’s uncompromising focus on safety, which has made the company’s vehicles among the safest on the road.

Echoing Musk’s vision for safe autonomous driving

Zhu’s post quoted Musk’s statement from 2021, where the CEO reportedly stated that FSD must avoid accidents even if the most ridiculous events happened in the middle of the road. Zhu stated that beyond everything, Tesla’s systems like Autopilot and FSD are designed to keep passengers safe.

“Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” Zhu stated.

“The prime directive, the absolute priority, is to minimize the probability of injury to yourself or to anyone on the road, to pedestrians, or anything like that. It can’t be dependent on the road markings being correct.”

Tesla leadership rallies behind global FSD rollout

Tom Zhu, who previously led Tesla China through its record-breaking growth phase, now oversees automotive operations worldwide. He has reportedly become a problem solver for Elon Musk over the years, with previous reports stating that he was brought in to help Giga Texas optimize its vehicle production ramp.

Zhu’s comments may sound ambitious, but FSD has proven that it values safety above all else over the years. This was highlighted recently in an incident in Australia, when a Model Y was hit by what could very well be a meteor. Despite the impact and part of its windshield melting, the vehicle was able to drive safely and keep its passengers safe.

Elon Musk’s biggest tech rival just canceled his Tesla Roadster

“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait,” Altman said.

Elon Musk’s biggest tech rival just canceled his reservation for a Tesla Roadster, the supercar the company has been developing for nearly eight years.

Sam Altman, the CEO of OpenAI, announced on X on Thursday evening that he canceled his Tesla Roadster reservation, or at least is trying to:

Altman placed his Tesla Roadster reservation with a $50,000 deposit way back on July 11, 2018. However, he recently decided that he had waited long enough and decided to email the company to officially cancel the order.

“Hi, I’d like to cancel my reservation. Could you please refund me the $50k?” Altman emails to reservations@tesla.com.

He then received an immediate response, but not from Tesla. Instead, it was a bounce-back message from Google, stating that the message could not be delivered to the email because it was not active.

Altman then provided a reason for his cancellation, and it was not related to the intense rivalry he had with Elon Musk:

“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait.”

Altman and Musk have a lengthy history with one another that dates back to 2015, when OpenAI was created. The feud has resulted in lawsuits over breaching founding agreements by prioritizing profits.

Musk has been especially critical in recent years because of Altman’s decision to turn OpenAI into a for-profit business that he says is “built on a lie.”

This year, Musk offered over $97 billion to buy OpenAI, and a judge blocked his request to stop the company from being converted into a for-profit in March.

OpenAI then countersued Musk in April, while xAI, Musk’s company, sued OpenAI for allegedly stealing secrets through poached employees in September.

Regarding the Roadster, Tesla has been developing it for several years and has delayed its release for five consecutive years. The company says it will have a demo of what it has changed since it was unveiled in 2017 later this year, but no date has been set quite yet.
