SpaceX’s first flight-proven Starship could fly again, says Elon Musk
Elon Musk says that SpaceX wants to reuse its first flight-proven Starship prototype, although the rocket’s second hop might come after the debut of a totally different ship.
On August 4th, for the first time ever, a full-scale Starship prototype measuring some 9m (30 ft) wide and 30m (~100 ft) tall lifted off from SpaceX’s Boca Chica, Texas test facilities. Just three weeks shy of the first anniversary of Starhopper’s last flight test, Starship serial number 5 (SN5) essentially repeated the stubby prototype’s 150m (~500 ft) hop before (relatively) gently landing on an adjacent concrete pad.
Over the last several days, SpaceX has gradually been working through the unprecedented task of inspecting, safing, and relocating a flight-proven Starship. At the same time, the company has to check out the fixed launch mount structured that supported the test flight and provided Starship with power, propellant, and wired communications. As teams work to get both ship and mount ready for round two, CEO Elon Musk has taken to Twitter to discuss some of SpaceX’s nearer-term goals and plans for Starship testing – including SN5’s role in them.
Starship SN5’s hop debut was a spectacular success for SpaceX, verifying that steel and radically simple and manufacturing techniques can quickly build a cheap pressure vessel capable of controlled flight. The flight also reaffirmed that the next-generation Raptor engine is capable of operating uninterrupted for at least ~50 seconds, although Starhopper’s 150m hop proved the same thing some 20 engine prototypes and 13 months prior.
Still, while it unequivocally proved that SpaceX is on the right track, both the lead-up to Starship SN5’s hop and the hop itself hint that a few kinks will still need to be worked out. Notably, during SN5’s hop, part of Raptor engine SN27 appeared to catch fire at some point after ignition, producing substantial flames that lasted for at least 10 seconds. For any rocket engine, an onboard fire is always a possibility, but most engines are either designed to tolerate the inhospitable environment they create or heavily insulated from it.
Festooned with sensitive wires and harnesses, Raptor prototypes are likely not meant to experience an extended onboard fire and remain functional, but SN27 nevertheless did just that. At a minimum, Starship SN5 thus likely needs a new Raptor engine before it can begin to prepare for a second hop.
The prototype will also assuredly need several new landing legs after destroying at least two during its launch and landing debut. It’s worth pointing out that the leg damage visible above is almost certainly the result of an intentional design choice, ensuring that landings slightly rougher than expected transfer most of their stress into Starship’s legs instead of its hull. Given just how simple they appear, the current leg design likely makes them effectively disposable, allowing SpaceX to focus its effort on unsolved problems as a more refined and reusable leg design comes to fruition.
Aside from confirming that SpaceX at least intends to reuse Starship SN5 on future hops, Musk revealed that he wants to refine the launch procedure until the company is able to easily perform multiple Starship hops per day. This suggests that the next one or several months could be chock full of Starship hop attempts. Musk also noted that Starship SN6 – a prototype built along SN5 and effectively completed weeks ago – would likely attempt its first flight before SN5 hops a second time. SpaceX began stacking the upgraded Starship SN8 prototype just a few days ago, raising the question of whether Starship SN6 would be made redundant before it could even left the factory.
Thankfully, it seems that the ship will instead be able to work alongside its sister (SN5) to help SpaceX simplify and expedite Starship test and launch operations. As of now, it’s unclear when SpaceX intends to restart Starship testing, but Musk’s comments point towards the next test happening far sooner than later.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles
Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.
The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.
As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality.
“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.
When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.
After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”
“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.
Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.
During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.
As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.
Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.
While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing.
“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.
“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said.
The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.
Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”
Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.
“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all.
“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.
