SpaceX has finished its third full-scale Starship prototype and rolled the rocket’s tank and engine section to a nearby launch pad just a matter of weeks after work began, now ready to prepare for a potentially imminent Starhopper-style hop test.

SpaceX’s rapidly-growing Boca Chica, Texas Starship factory is now producing so much rocket hardware that it’s hard to track any single vehicle’s birth. However, it still appears that SpaceX’s Texas team managed to complete the Starship SN3 prototype in less than a month, measured from first steel ring stacking to the ship’s integrated business end being transported to the launch pad. Simultaneously, the company fabricated, assembled, and tested an entirely separate Starship test tank, verifying that a design flaw that likely lead to Starship SN1’s February 28th destruction had been rectified.

Featuring the same design improvements that allowed that Starship test tank to become the first to pass proof testing intact, Starship SN3 is the best candidate yet to kick off true wet dress rehearsal (WDR) and Raptor engine static fire testing. Both will require real liquid methane and oxygen propellant to be loaded, potentially turning Starship SN3 into the equivalent of many tons of TNT if things were to go south. To be clear, there is a significant chance that such an early, rapidly-built prototype will not survive its upcoming test campaign. Nevertheless, Starship SN3 has the numerous lessons learned from both the successes and failures of all previous vehicles built into it, giving it the best chance yet. Still, the massive rocket will need to pass one or several less risky tests before it can begin to attempt more groundbreaking feats.

Set to follow in the footsteps of all previous Starship test articles, SpaceX will soon kick off Starship SN3’s test campaign with a liquid nitrogen proof test – still extremely cold (i.e. cryogenic) but chemically neutral (i.e. can’t explode). Delivery trucks were spotted topping off SpaceX’s liquid nitrogen supplies just yesterday. The company also has a four-hour road closure scheduled to start at 5pm CDT (22:00 UTC) today, shortly after this article went live.

One month (30 days) later, Starship SN3’s completed engine section was craned onto a Roll Lift transporter in the middle of the night, arriving at SpaceX’s nearby launch pad on March 29th. (NASASpaceflight – bocachicagal)

If it isn’t delayed, that March 29th road closure is likely meant to allow SpaceX to pressurize Starship SN3 with liquid nitrogen, pushing it beyond flight pressures (6 bar/90 psi) in what’s known as a proof test. If successful, it would verify that the rocket’s tank section is sound while also bringing it to cryogenic temperatures, potentially strengthening the steel with cryogenic hardening.

Just hours later, SpaceX technicians lifted the Starship tank section onto the launch mount, where it will be prepared for imminent proof testing. (SPadre)

Beyond those initial plans, the FAA license SpaceX used to support Starhopper’s July and August 2019 hop tests may actually enable test flights of full-scale Starship prototypes, too. Incredibly, according to Cameron County, Texas beach closure requests made on March 23rd, SpaceX’s goal is to prepare Starship SN3 for a Raptor engine static fire test as early as April 1st (no fool), followed by a potential 150m (500 ft) Starhopper-style flight test on April 6th.

For obvious reasons, delays to that ambitious schedule – particularly the flight test – are extremely likely, but Starship SN3 is now unequivocally at the launch pad. Stay tuned for updates on the rocket’s potentially imminent proof test and the impacts that might have on future tests.

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.
