SpaceX’s Starhopper cleared by FAA for second and final flight test as locals urged to exit homes
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.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
