SpaceX rolls out first new Starship prototype in nine months

Published

on

For the first time in more than nine months, SpaceX has rolled a new Starship prototype to its Starbase, Texas launch facilities in the hopes of kicking off qualification testing in the near future.

The new activity exemplifies just how different – and more subdued – Starbase’s last year has been compared to the year prior. However, it also signals new hope for a significantly more eventful 2022 as SpaceX once again finds itself preparing for Starship’s first orbital launch attempt – albeit with an entirely different rocket.

The last time SpaceX rolled a new and functional Starship prototype from the factory to the test stand was on August 13th, 2021, when Starship S20 was transported back to the pad for the second time that month. On August 5th, the same unfinished Starship was stacked on top of Super Heavy booster B4, briefly assembling the largest rocket ever built. With the luxury of hindsight, it’s now clear that that particular milestone was more of a photo-op than a technical achievement. Nonetheless, Ship 20’s path was far more productive than Booster 4’s. The Starship returned to the Starbase factory for a few days of finishing touches before arriving back at the pad on August 13th. Only in the last week of September did Ship 20 finally begin its first significant tests, followed by its first Raptor static fire in mid-October. In mid-November, Ship 20 completed the first of several successful six-Raptor static fires.

Ultimately, by the time Ship 20 was retired in May 2022, the Starship was arguably fully ready to attempt to reach orbit or at least perform some kind of ambitious hypersonic test flight. However, Super Heavy Booster 4 never made it even a fraction of the way to a similar level of flight readiness and SpaceX never received the FAA environmental approval or launch license needed for an orbital launch attempt.

Only now, in May 2022, does it finally look likely that SpaceX will finally receive the necessary permissions for a limited orbital test flight campaign in the near future. While it’s hard to say if Booster 4 and Ship 20 could have supported some kind of launch campaign if permission had been granted months ago, what’s clear is that all aspects – flight hardware, pad hardware, and bureaucracy – have been chronically delayed to the point that Booster 4 and Ship 20 are now heavily outdated.

In their place, now, stand Super Heavy B7 and Starship S24 – the new ‘chosen ones’ assigned to Starship’s orbital launch debut. Both feature extensive design changes and account for an upgraded version of the Raptor engine and countless lessons learned over the better part of a year spent troubleshooting and testing their predecessors. While it did get off to a rocky start, Booster 7 has already completed several cryogenic proof tests and is in the middle of being outfitted with 33 new Raptor engines.

On the other hand, perhaps indicating SpaceX’s satisfaction with Ship 20’s performance, Starship S24 has been on the back burner in comparison. Only on May 26th, 2022 did SpaceX finally finish the prototype to the point that it was ready to begin qualification testing. Missing hundreds of TPS tiles and an aerocover cap, Ship 24 was quickly moved into position at a sort of drive-by test stand where it appears the prototype will first need to pass basic pressure and cryogenic proof tests.

If it passes those tests, SpaceX will then install Ship 24 on a suborbital launch and test stand (Suborbital Pad A) that has been significantly modified for qualification testing. Rather than leaping straight into static fires, SpaceX will minimize the risk of catastrophic failure by first using hydraulic rams to simulate the thrust of six Raptor V2 engines while Starship’s steel tanks and plumbing are chilled to cryogenic temperatures. Only after Ship 24 completes stress testing will SpaceX install new Raptor engines and prepare to replicate Ship 20’s success with several static fires.

Thanks to Raptor V2’s improvements, Ship 24 will likely need to withstand around 1400 tons (~3.1M lbf) of thrust at liftoff – almost 25% more than Ship 20 ever experienced. Beyond a sturdier thrust section, Ship 24 is also the first Starship SpaceX has outfitted with a next-generation nose; the first with a significant landing propellant (‘header’) tank redesign; and the first with a potentially functional payload bay and door.

Assuming Ship 24 passes all planned cryoproof and thrust simulation tests, it remains to be seen if SpaceX will return the Starship to Starbase factory facilities or – like with Ship 20 – install Raptors and finish its heat shield and thermal protection while sitting on the test stand. SpaceX has two test windows currently scheduled: one from 6am to 12pm CDT on Friday, May 27th and the other from 10am to 10pm CDT on Tuesday, May 31st.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.


Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.

Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”

The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.

Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.

Configuration Seats 0 to 60 mph
Performance 2 under 1.6 s
Thrust 2 under 0.9 s
Rocket 1 under 0.59 s

Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

  • Road use: Tesla notes the car is not approved for public road use, and that Rocket isn’t available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store

Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.

Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.

The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.

The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.

The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.

The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.

Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.

So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
