SpaceX Starship to test landing upgrades after two explosions
After two Starship prototypes aced their high-altitude launch debuts only to suffer last-second landing failures for unique reasons, SpaceX is gearing up for a third launch as early as this week.
Crucially, though Elon Musk’s levelheaded realism (or pessimism) has often seemed to underestimate the actual odds of success, the SpaceX CEO is substantially more confident on Starship’s third launch attempt than he was on the first flight two months ago. Back when Starship serial number 8 (SN8) was preparing to attempt the program’s first high-altitude launch, Musk pegged the probability of a successful launch, freefall, and landing at ~33%.
As it turned out, he wasn’t wrong, but Starship SN8 ultimately made far closer to a total success than almost anyone – inside SpaceX or not – expected it to get on the first try. Less than two months later, Starship SN9 suffered a similar last-second landing failure more than six minutes into the flight, though the root causes of both failures were unique. 
In other words, both flight tests served their nominal purpose, uncovering two failure modes that would have eventually reared their heads one way or another. With SN8, Starship was unable to maintain enough pressure in its secondary landing fuel tank to supply two Raptor engines with enough fuel for a landing burn. Starship SN9 failed a few seconds before SN8 when one of the two Raptor engines needed for a flip and landing burn never ignited, causing the rocket to smash into the ground at an angle relative to SN8’s tail-down impact.
As previously discussed on Teslarati, Elon Musk eventually revealed his opinion that SN9’s engine-out failure was potentially avoidable and that SpaceX would change the way future Starships attempt to land in a bid to add more redundancy.
“While SpaceX obviously hasn’t spun around and fixed a complex Starship propulsion issue in a matter of days, Musk eventually revealed his opinion that he, his engineers, or some combination of both “were too dumb” to exploit one obvious way to mitigate the risk of engine failure during [Starship SN9’s] flip and landing. That ‘obvious’ tweak: reignite all three of Starship’s available landing engines, not just two.”
By igniting not just two – but all three – Raptor engines during Starship’s flip burn, SpaceX could essentially perform a midair static fire, giving the rocket’s flight computer a few seconds to analyze performance and downselect to the two healthiest engines for the final landing burn. With that change implemented, Starship would theoretically have enough redundancy to land if only two of its three sea-level Raptors performed nominally.
Currently installed on one of two ‘suborbital stands’ at SpaceX’s South Texas launch pad, Starship SN10 will be the first high-altitude prototype to attempt that three-engine flip burn and on-the-fly downselect. Musk says his confidence that SN10 will successfully land is now 60%, an almost twofold improvement over SN8. Starship SN10 could potentially fly as early as this week, though the prototype still needs to complete a nominal three-engine static fire test and the launch has yet to receive FAA approval.
Further down the road, Musk says that SpaceX is working hard to improve Raptor’s deep throttle performance, potentially allowing future Starships to burn two – or even three – engines all the way to touchdown for even more redundancy. Deep-throttling large, complex rocket engines is extraordinarily difficult, though, so that upgrade is likely no less than several months away. In the meantime, Starship SN11 is effectively complete and Starships SN15 through SN18 are being assembled to support a relentless flight test campaign as SpaceX works towards orbital flights.

Tesla Robotaxi test units spotted in new region ahead of launch
These validation units are used to gain additional data for Tesla’s internal use, or even potentially for regulatory purposes that the company can share with agencies that will eventually grant a license to operate Robotaxi in the state.
 
														Tesla Robotaxi test units are being spotted in various new regions ahead of their launch in new states. Tesla is aiming to launch in at least a few new states in the coming months as it is ramping up hiring for the Robotaxi program and aiming to expand its ride-hailing service.
Already active in Austin, Texas, and the California Bay Area, Tesla is looking to expand its Robotaxi operations to new states. It’s had its eyes set on Nevada, Florida, and Arizona, which have seemed to have the most movement of the three prospects over the past month or so.
That trend is continuing.
Earlier this month, we reported on two Robotaxi units spotted testing with LiDAR rigs for ground truth validation in Gilbert, Arizona. Noted Cybertruck owner and enthusiast Greggertruck spotted the two units traveling on a highway.
Now, those same two units, or at least they appear to be, were spotted in Scottsdale, which is also a suburb of Phoenix, like Gilbert is, with the same LiDAR rigs:

These validation units are used to gain additional data for Tesla’s internal use, or even potentially for regulatory purposes that the company can share with agencies that will eventually grant a license to operate Robotaxi in the state.
Tesla is not a company that utilizes LiDAR for its everyday self-driving efforts, as it has utilized only cameras for the past several years.
Tesla Vision, as the company calls it, is what CEO Elon Musk feels is needed to achieve a fully autonomous network of vehicles, which will eventually need zero supervision for passenger transportation.
LiDAR is utilized by other companies, like Waymo, but Tesla has maintained that it is not necessary for several years. Musk has called it a “crutch” for achieving the proper self-driving tech, and the company only uses it for an additional bit of data.
Tesla has been operating its Robotaxi service in Austin since late June, and it has expanded its service area in the city to nearly 300 square miles, with its most recent expansion occurring earlier this week.

Tesla’s popular side business is going to get bigger, Elon Musk says
It took several years to get the Diner developed, built, and opened. On July 21, Tesla launched the Diner to the public at 4:20 p.m. local time (of course), after years of development. Musk first offered the idea of a drive-in Supercharger Diner back in December 2018.
 
														Tesla will open two new Diner locations in the United States after its first location in Los Angeles has been a raging success, as it is constantly packed and serving food for 24 hours a day, every day.
Tesla CEO Elon Musk said that the initial Diner location on Santa Monica Boulevard is “going well,” and based on reviews and its constant out-the-door lines, it is safe to say it has been a major outlet of interest for people in the area.
It features two massive movie screens, a menu that is locally sourced and has been created by a world-class chef, and Supercharging for EVs. It truly is the perfect stop for those who are hungry, need entertainment, or need a quick charge.

So far, Tesla has not released too many details on the success of the restaurant, but it did state in a graphic for its Q3 Supercharging stats that it sold roughly 50,000 burgers at the Diner in Q3, roughly 715 each day. Burgers are not the only thing on the menu, either.
With how well it has gone, Musk is now considering the possibility of new locations that are notable to Tesla, including Austin and Palo Alto.
On Friday, Musk revealed he believes it “probably makes sense to open one” near Gigafactory Texas and Engineering HQ in Palo Alto:”
The futuristic Tesla Diner is going well. Probably makes sense to open one near our Giga Texas HQ in Austin and engineering HQ in Palo Alto. 😋 https://t.co/l0DUtR8CFg

By 2023, Tesla had secured building permits and broken ground on the site in September of that year.
Since its launch, it has been a popular hotspot for Tesla fans and others to visit, although it has attracted unwanted attention from protestors as well.

They look hungry. If they walked inside and ordered some food, maybe they’d stop yelling into microphones and threatening Musk.

Elon Musk’s AI empire grows as xAI leases Palo Alto space near Tesla
The expanding footprint of Elon Musk’s companies in Palo Alto bodes well for the CEO’s plans in the area.
 
														Elon Musk’s artificial intelligence startup, xAI, is expanding its Silicon Valley footprint, leasing roughly 105,000 square feet of office space at Palo Alto’s Page Mill Center, just blocks away from Tesla’s engineering complex.
Musk’s deepening Silicon Valley footprint
People familiar with the matter have informed the San Francisco Business Times that xAI’s lease at Page Mill Center may already have been finalized, adding to the company’s existing headquarters at 1450 Page Mill Road. The two offices share a parking lot, reflecting Musk’s strategy of consolidating his ventures. Tesla’s engineering hub is also just a few blocks away.
The new offices form a growing cluster of Musk-led companies in the heart of the Valley and come as xAI has listed over 250 job openings. These include listings for engineers, designers, and technical staff, among others.
xAI’s aggressive hiring push hints at rapid scaling, which makes quite a lot of sense considering the company’s ambitious projects. xAI oversees the large language model Grok and other AI initiatives such as the newly launched Grokipedia, and the startup has also acquired the social media platform X. Real estate owner Hudson Pacific Properties, the owners of Page Mill Center, have so far declined to comment.
AI demand and Silicon Valley’s office rebound
Silicon Valley’s office market, long subdued by remote work trends, is seeing renewed activity from AI firms. Hudson Pacific told investors this summer that tenant demand has reached a three-year high, with over half of new leases driven by artificial intelligence companies. Vacancy rates have now fallen for four straight quarters to 16.6% as well, CBRE reported.
The expanding footprint of Elon Musk’s companies in Palo Alto bodes well for the CEO’s plans in the area. Musk, after all, has previously butted heads with officials, resulting in his two biggest ventures, electric vehicle maker Tesla and private space company SpaceX, officially relocating their headquarters to Texas.
