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pad hardware, and bureaucracy – have been chronically delayed to the point that Booster 4 and Ship 20 are now heavily outdated.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.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access

Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.

Published

Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.

Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.

Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.

Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.

The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.

How to use Grok Bot to block spam calls and texts

Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.

Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.

The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.



Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.

For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.

The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.

Tesla’s flying Roadster just revealed something bigger than the car

Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.

The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.

Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.

The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.

The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.


Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.

The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.
