Less than a day after SpaceX successfully hopped a full-scale Starship prototype for the first time, the company has begun stacking the next rocket and Elon Musk is talking next steps.

Almost immediately after Starship SN5 took to the sky on a 150m (500 ft) hop debut, SpaceX CEO Elon Musk was talking about the company’s next near-term goals for the next-generation launch vehicle’s test program. To an extent, he had already offered a rough overview through various interviews and tweets over the last year or so. Aside from continuing to gradually refine Starship and Super Heavy designs and the processes used to manufacture and test those rockets, a few major proofs of concept stand between SpaceX and total confidence in the current architecture.

As far as basic rocketry goes, SpaceX’s 150m Starship hop has functionally proven that the company’s exotic, rule-of-thumb-breaking approach to Starship production and assembly can be feasibly refined into something capable of producing extraordinarily cheap orbital-class rockets. While a massive achievement, it doesn’t guarantee that the rockets produced will be reusable – let alone rapidly and easily reusable.

As of now, it can be safely stated that SpaceX has solved all major challenges involved in routinely and reliably landing and reusing orbital-class rocket boosters (first stages). It’s hard and surprises are always a possibility, but the landing records of Falcon 9 and Falcon Heavy boosters speak for themselves. For the colossal booster Starship needs to reach orbit, the Falcon family’s success means that Super Heavy recovery and reuse is more a question of “when” than “if”.

Starship, on the other hand, is going to offer many different challenges – some unprecedented for SpaceX and others unprecedented in the entire history of spaceflight. For Starship to be able to support a level of reuse compatible with what the Super Heavy booster is likely to achieve, SpaceX will have to create the biggest and most effortlessly reusable orbital-class spacecraft ever built.

Even heavier than NASA’s Space Shuttle orbiter, Starship will also rely almost entirely on the unproven technology of on-orbit cryogenic propellant transfer to reach beyond low Earth orbit (LEO). To survive orbital-velocity reentries while still being rapidly and cheaply reusable, Starship will further have to push the envelope of heat shield technologies. Last but certainly not least, in its current iteration, Starship relies on a truly unprecedented style of recovery to efficiently land back on Earth.

It’s this last bit where CEO Elon Musk’s recent comments and recent activity at SpaceX’s Starship factory come in. According to Musk, SpaceX intends to perform at least several more smaller hops (a la SN5) “to smooth out [the] launch process.” It’s unclear which prototype(s) will be involved in that series of hops but after SpaceX is satisfied with the state of launch operations, the plan is to “go high altitude with body flaps.” Based on past comments, it’s safe to assume that Musk is referring to a plan to launch a Starship to 20 km (~12 mi).

After reaching 20 km, Starship would orient itself belly down – a bit like a skydiver – and quite literally fall its way to ~1 km altitude before attempting an aggressive Raptor-powered pitch-over maneuver and last-second landing. By using Earth’s atmosphere much like a skydiver trying to slow down, Starship will theoretically be able to dramatically reduce the amount of propellant it needs to land.

That high-altitude launch and landing demonstration will also be the first time a Starship truly needs aerodynamic control surfaces (i.e. “body flaps”) to safely complete a flight test. According to NASASpaceflight.com info, Starship SN8 – also the first full-scale prototype to be built out of a different steel alloy – will be the first ship to receive functional flaps and a nosecone. If initial tests go according to plan, SN8 will also be the first ship to attempt a skydiver-style landing as described above. As far as full-scale aerodynamics goes, such a landing is loosely understood at best. For an orbital-class spacecraft, it’s even more of a wildcard.

Regardless, just hours after Starship SN5’s successful hop debut, SpaceX began stacking the first of several already finished Starship SN8 sections. Based on the assembly of past prototypes, the ship’s tank section could reach its full height just a few weeks from now, while subsequent nosecone and flap installations are uncharted territory.

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.

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!
