After a full two weeks spent waiting for an FAA permit, SpaceX CEO Elon Musk and local South Texas authorities appear to be preparing Starhopper for a second major flight test as early as Monday, August 26th.

Assuming the FAA comes through with a permit, Starhopper is scheduled to lift off no earlier than 5pm EDT (21:00 UTC) on August 26th for a flight test expected to smash the low-fidelity Starship prototype’s previously altitude record of ~20m (65 ft). Confirming initial reports from NASASpaceflight.com, Musk also stated that Starhopper’s second flight will be its last, after which the steel rocket test-bed will be converted for stationary use at SpaceX’s South Texas facilities.

Prior to Musk tweeting that Starhopper may be nearing approval for its next flight, the SpaceX CEO revealed that delays were centered around the FAA’s apparent unwillingness to permit the vehicle’s next flight. Musk specifically stated that the FAA wanted more “hazard analysis”, meaning that the US aviation administration had concerns that Starhopper could pose a serious threat to local residents in a tiny housing development known as Boca Chica Village.

Technically speaking, Boca Chica Village is just 1.5 miles (2.4 km) away from SpaceX’s Starhopper launch facilities, where the vehicle is expected to reach a maximum altitude of no more than 200m (650 ft) as early as August 26th. FAA regulations tend to be prescriptive and extremely rigid, understandable given the breadth of US aviation-related activities the agency is tasked with regulating. However, a basic back-of-the-envelope analysis of Starhopper’s 200m hop suggests that the risk to local residents – even those as few as 1.5 miles away from the test – is minuscule.

Based on Starhopper’s inaugural flight, its lone Raptor engine – producing up to 200 tons (450,000 lbf) of thrust – is not exactly capable of rapidly moving the Starship prototype. For all accounts and purposes, Starhopper is a spectacularly heavy hunk of steel with the aerodynamics of a cylindrical brick – capable of flight solely through the brute-force application of a literal rocket engine. To make it even half of the distance from its launch site to the Village, Starhopper would have to remain in controlled flight while radically deviating from its planned trajectory, all while its flight termination system (FTS) – explosives meant to destroy the vehicle in a worst-case scenario – completely fails to activate.

As evidence of the apparent lack of perceived risk to local residents, Cameron County, Texas officials distributed flyers to Village residents advising – but not requiring – those choosing to remain at their homes during the test to go outside during Starhopper’s next flight. This is recommended to avoid flying glass in the event that the vehicle explodes, potentially shattering windows with the shockwave that could result, but clearly demonstrates the fact that county officials believe there is a near-zero chance of Starhopper actually impacting anywhere near the houses.

Ultimately, Starhopper’s limited flight tests clearly pose little to no actual risk to residents, but this chapter does raise a far more significant question: what happens once Starship Mk1 is ready and the flight tests SpaceX is pursuing involve distances and heights on the order of several, tens, or hundreds of kilometers? For now, answers will have to wait til a later date.

A Hop and a skip into retirement

Aside from the delays and apparent lack of consensus on the safety of Starhopper’s minor hop tests, Musk confirmed that the prototype’s second test flight ever will likely be its last, providing some interesting insight into SpaceX’s next steps. Most notably, the fact that SpaceX is willing and ready to fully retire Starhopper after such a limited test series serves as a fairly confident statement that orbital-class Starship Mk1 (Texas) and Mk2 (Florida) prototypes are extremely close to flight-readiness.

Roughly a month ago, Musk tweeted that those Starship prototypes could be ready for their first flights as early as mid-September to mid-October, “2 to 3 months” from mid-July. In additional comments made on August 20th, Musk stated that his planned Starship presentation would be delayed in light of Starhopper’s own delays, and is now instead expected to occur around a major Starship Mk1 integration milestone in “mid September”.

As previously discussed on Teslarati, Starhopper’s brief service life is entirely unsurprising, delayed by issues with Raptor engines to the point that SpaceX’s far more valuable Starship prototypes – having made relentless progress – are already nearing completion. Once those Starships are ready for almost any kind of integrated testing, Starhopper will be made entirely and immediately redundant.

“According to Musk, either or both of those orbital-class prototypes could be ready for their inaugural flight tests as early as mid-September, perhaps just 1-2 months from now. Given that Starships Mk1 and Mk2 are significantly higher fidelity than Starhopper, the ungainly testbed will likely become redundant the moment that its successors are ready for flight. In other words, Starhopper is fast approaching the end of its useful life, and SpaceX’s fight for a 200m hop-test permit could ultimately be a waste of time, effort, and money if said permit doesn’t also cover Starship Mk1.”

On another positive note, CEO Elon Musk says that Starhopper won’t be ‘retired’ to the scrapyard and will instead be lightly modified to serve as an in-situ test stand for Raptor engines, a useful addition once SpaceX South Texas moves on to multi-engine Starship and Super Heavy testing.

With any luck, SpaceX will attempt to livestream Starhopper’s second attempted flight. Stay tuned for updates on the 5pm EDT, August 26th test.

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!
