SpaceX has begun to upgrade its South Texas Starship launch pad in anticipation of the completion of the next full-scale rocket prototype, photos of which CEO Elon Musk revealed just hours ago.

Working in parallel with efforts to repair damage caused by Starship serial number 1’s (SN1) violent February 28th test failure, SpaceX has managed to build, complete, and test an entirely separate ‘test tank’ and complete fabrication of a second full-scale Starship in a handful of weeks. Flexing the growing capabilities of the impressive Boca Chica, Texas Starship factory SpaceX has sprung up in just three months, the company is working around the clock to build not just one – but several – Starship prototypes simultaneously.

A successful March 9th tank test designed to prove a new thrust structure design managed to do just that less than two weeks after the same faulty part brought about Starship SN1’s demise. In the two weeks since that its test completion, SpaceX has been busy welding, stacking, welding, and stacking several separate sections of the next Starship prototype, known as SN3. Potentially a matter of days away from structural completion, focus has recently shifted to the launch pad the ship will be tested at. In the last few days, SpaceX technicians have begun to install a bizarre, new structural element on the mount Starship SN3 will be secured on top of, hinting at the goals of the rocket’s first test campaign.

Squeezing in alongside efforts to repair the propellant lines that run into the launch mount, upgrades began on March 24th as a SpaceX team worked to install what looked like an incredibly sturdy tripod (with four ‘legs’, of course). Thanks to familiar testing done with SpaceX’s most recent Starship tank prototype, the purpose of the launch mount’s newest appendage quickly became clear.

During the Starship SN2 tank’s thrust structure (‘thrust puck’, per Elon Musk) test campaign, SpaceX debuted the concurrent use of a beefy hydraulic jack to simulate the forces a Raptor engine static might produce. Capable of producing upwards of 200 metric tons (440,000 lbf) of thrust at full power, SpaceX will likely begin Starship static fire tests with a single Raptor engine. As soon as a Starship prototype completes one or several single-engine test fires, the plan is to install three sea level-optimized Raptor engines and repeat static fire tests.

Before that triple-engine static fire milestone, a first for the cutting-edge Raptor engine, SpaceX needs to verify that Starship’s thrust structure can stand up to the ~600 tons (~1.3M lbf) of force it will be subjected to during such a test. Sitting on a much smaller stand, Starship SN2 used a single hydraulic jack and temporary stand to simulate a single engine’s thrust. Starship SN3, sitting much higher above the ground, will need three jacks to simulate three Raptors.

As such, it looks likely that Starship SN3’s first cryogenic tank proof test – filling the vehicle with inert liquid nitrogen – will coincide with a second dedicated stress test of a Starship thrust structure, hopefully proving itself capable of surviving the force of three Raptor engines at full thrust. While orbital-class Starships will need three more vacuum-optimized Raptor engines, three sea-level engines are all SpaceX needs to begin flight tests with suborbital prototypes.

Based on an unofficial analysis of existing photos, it appears that every single major structural piece of Starship SN3 – excluding legs and fins – is nearing completion, even including the ship’s shiny nosecone. Likely to head to the launch pad for its first tests as soon as the tank section alone has been completed, just one stacking event remains before said tank section reaches its full height. Right now, both of those parts have been moved to a dedicated Vehicle/Vertical Assembly Building (VAB) and are probably no more than a day or two away from being joined*. Perhaps just a day or two after that milestone, SpaceX will likely transport the massive rocket to the launch pad to begin preparing for its first proof tests.

*Around 3am local time, SpaceX technicians stacked Starship SN3’s two main segments, completing its tank and engine section.

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.

Tesla Roadster Highlights

  • 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!
