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 says it denied Musk CEO replacement report before it was published

Tesla says it responded to the WSJ’s request for comment, denying that it was in search of a new CEO to replace Elon Musk.

Tesla said that it denied seeking a replacement for CEO Elon Musk before a report was published claiming the company was considering a new frontman.

Last night, The Wall Street Journal reported that Tesla’s Board of Directors was looking for Musk’s replacement after he had devoted too much time to his role within the government. The publication revised its headline to the report no fewer than five times, initially stating the company was still seeking a replacement.

By the time the headline revisions were complete, it had outlined that Tesla had looked for a replacement a month ago, but had stopped its search following Musk’s commitment to Tesla during the company’s earnings call last month.

Shortly after the report surfaced, Board of Directors chairwoman Robyn Denholm officially issued a statement on behalf of Tesla:

“Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company. This is absolutely false (and this was communicated to the media before the report was published). The CEO of Tesla is Elon Musk and the Board is highly confident in his ability to continue executing on the exciting growth plan ahead.  – Robyn Denholm.”

Tesla Board Chair slams Wall Street Journal over alleged CEO search report

Interestingly, Denholm’s statement indicates it had responded to a request for comment from the Wall Street Journal before the report was published. This is especially interesting because Tesla does not typically respond to media outreach, as it dissolved its media department several years ago.

Tesla typically makes its statements publicly on X.

Musk also responded to the report, indicating that the WSJ had committed an “extremely bad breach of ethics” by publishing a “deliberately false article” that did not include Tesla’s “unequivocal denial beforehand.”

Industry leaders such as Elon Musk have always maintained that autonomous robotaxis will make roads safer. A recent blog post from Waymo about the safety of its self-driving cars suggests that Musk’s sentiments are on point.

Way More Safety

Waymo Driver is already reducing severe crashes and enhancing the safety of vulnerable road users. As per a new research paper set for publication in the Traffic Injury Prevention Journal, Waymo Driver had outperformed human drivers in safety, particularly for vulnerable road users (VRUs).

Over 56.7 million miles, compared to human drivers, Waymo Driver achieved a 92% reduction in pedestrian injury crashes. It also saw 82% fewer crashes with injuries with cyclists and 82% fewer crashes with injuries with motorcyclists. Waymo Driver also slashed injury-involving intersection crashes by 96%, which are a leading cause of severe road harm for human drivers. Waymo Driver saw 85% fewer crashes with suspected serious or worse injuries as well.

What They Are Saying

Mauricio Peña, Waymo’s Chief Safety Officer, was optimistic about Waymo Driver’s results so far. “It’s exciting to see the real positive impact that Waymo is making on the streets of America as we continue to expand. This research reinforces the growing evidence that the Waymo Driver is playing a crucial role in reducing serious crashes and protecting all road users,” the Chief Safety Officer noted.

Jonathan Adkins, Chief Executive Officer at Governors Highway Safety Association, also noted that Waymo’s results are very encouraging. “It’s encouraging to see real-world data showing Waymo outperforming human drivers when it comes to safety. Fewer crashes and fewer injuries — especially for people walking and biking — is exactly the kind of progress we want to see from autonomous vehicles,” Adkins stated.

Tesla hints at June 1 launch of Robotaxi platform in Austin

Tesla has hinted at a potential launch date for the Robotaxi service in Austin, Texas.

Tesla just dropped its biggest hint yet about the potential launch date of its Robotaxi ride-hailing platform in Austin, Texas, shedding more light on when to expect it to take off.

In preparation for the ride-hailing service to launch, Tesla has been in talks with the City of Austin for months. It has also spent recent months bolstering its Full Self-Driving suite, aiming for it to handle initially supervised rides with the use of teleoperators to keep things safe and dependable, at least early on.

The company has also said that it expects the Robotaxi service, which will drive passengers in Tesla Model Y vehicles to start, to launch in Austin in June. However, Tesla has not given an exact date.

Now, Tesla is hinting that Robotaxi could launch on June 1, based on a very vague X post it published on May 1:

Of course, this is extremely speculative. However, it’s the first time Tesla has made any suggestions about a potential launch date, so it’s worth taking it seriously.

While the automaker has often missed timelines in the past, most notably the launch of a “feature-complete” Full Self-Driving platform, this is the first time we’ve seen Tesla be so adamant and truly reiterate a target date.

Tesla has not shied away from this June date for the Robotaxi launch yet, something that is worth noting as we move closer to June. All signs point toward Tesla being able to come through on this timeline, and it could be one of its biggest accomplishments yet on the grand scheme of things. The Robotaxi rollout will be controlled and small to start, the company noted on its most recent Earnings Call.

CEO Elon Musk said:

“The team and I are laser-focused on bringing robotaxi to Austin in June. Unsupervised autonomy will first be solved for the Model Y in Austin.”

At first, it also seems as if the first Robotaxi rides will be available to a select group, as Musk said the ability to order one will not be available to the general public until later in the month. He also said the initial fleet will be between 10 and 20 vehicles:

“Yeah. We’re still debating the exact number to start off on day one, but it’s, like, I don’t know, maybe 10 or 20 vehicles on day one. And watch it carefully. They scale it up rapidly after that. So, we want to make sure that you’re paying very close attention the first time this happens. But, yeah, you will be able to — end of end of June or July, just go to Austin and order a Tesla for autonomous drive.”

While the June 1st date of the Robotaxi launch is extremely speculative, Tesla seems convinced that its vehicles could already handle this task. It would be something to see them come through on this date, especially on the first day of the month.
