Hours after a successful Falcon 9 launch, a SpaceX Starship prototype has kicked off a challenging gauntlet of tests for the fifth time in hopes of becoming the first to take flight.

Five days after the ~30m (~100 ft) tall steel rocket was transported from the factory to the launch pad, SpaceX has fully integrated it with a brand new launch mount – built from scratch after operator error caused Starship SN4 to explode and destroy the prior mount. Assembled and outfitted with great haste, the new mount was completed just a day or two before Starship SN5 was moved to the pad and installed on top of it.

Triggered by a quick disconnect umbilical panel fuel leak that effectively caused a bomb-like fuel-air explosion, Starship SN4’s May 29th demise occurred shortly after a Raptor static fire test that was likely one of the last hurdles standing between SpaceX and the first full-scale Starship flight test. That fated static fire itself occurred a single day after SpaceX crossed a major regulatory milestone with an official FAA launch license for an effectively unlimited number of suborbital Starship flights. Now transformed into a pile of scorched scrap metal, Starship SN4 has passed the torch to Starship SN5.

Effectively identical to the gauntlet of tests Starship SN4 completed in the weeks prior to its destruction, Starship SN5 has kicked off its own test campaign with an ambient pressure test – a low-risk method of checking a pressure vessel for leaks. Starship SN5 apparently passed that first test without issue and SpaceX is now in the midst of loading the rocket tank section with cryogenic liquid nitrogen as a chemically neutral and nonexplosive stand-in for live liquid oxygen and methane propellant. (SN4 serves as a perfect illustration of why initial cryo proof tests are performed with LN2 instead of real propellant.)

SN4 was actually the first full-scale Starship prototype to survive a full cryogenic proof test, achieving 7.5 bar (~110 psi), so SN5’s success is far from guaranteed. Still, given SpaceX’s iterative, clockwork-like approach to development means that it’s far more likely than not that Starship SN5 will pass all the tests that its predecessor did – and then some.

If Starship SN5’s cryo proof is successful, SpaceX has a few options available. Depending on the level of confidence in SN5, SpaceX could proceed directly into installing a single Raptor engine on the rocket’s triple-engine thrust structure and move on to wet dress rehearsals (WDRs) with methane and oxygen propellant. If a more cautious approach is preferred, SpaceX could perform a WDR or two before installing a Raptor engine. Either way, once the WDR phase is complete, Starship SN5 can begin live Raptor engine testing, starting with turbopump prime and preburner tests and culminating in one or several static fires.

Finally, once preburner and static fires have been completed without issue, SpaceX can begin to seriously prepare SN5 for its inaugural hop test, likely targeting an altitude of ~150m (~500 ft) before landing a few hundred feet from the launch mount. For now, many steps remain in the interim before Starship SN5 is even close to a hop test, but it shouldn’t take long to find out how long we’ll have to wait.

Tesla preps to expand Robotaxi geofence once again, answering Waymo

Just days after Waymo responded to them, Tesla is preparing for a potentially massive expansion of the Robotaxi geofence.

Tesla is preparing to expand its Robotaxi geofence yet again, just days after Waymo responded to its initial broadening of the area.

Tesla launched its first expansion last week, less than a month after introducing Robotaxi rides in Austin.

The company opted for a very interesting shape for its geofence expansion, which was more of an indication that it could launch more rides in virtually any area of the city due to the new geofence it chose.

Waymo then responded to Tesla shortly after with an expansion of its own. After Tesla’s first expansion of its geofence, it had 42 square miles of Robotaxi-accessible travel region. This was larger than Waymo’s 37 square miles.

However, the Waymo expansion last week brought the company to a substantial 90 square miles of Austin:

Waymo responds to Tesla’s Robotaxi expansion in Austin with bold statement

Tesla appears to be ready to respond. Drone operator and Gigafactory Texas observer Joe Tegtmeyer spotted Tesla Robotaxi validation vehicles well west of downtown Austin in the area of Marble Falls, Texas.

This would significantly increase Tesla’s square mileage if it could manage to bring its geofence to that size:

The two companies are not directly responding to one another with these expansions, but it appears that there is a significant amount of competition underway, which ultimately benefits the consumers.

Waymo has been operating in Texas since March from a fully public perspective, while Tesla is still slowly expanding its test size for the Robotaxi fleet on a nearly daily basis. Tesla launched Robotaxi rides to a handful of Early Access Program members on June 22.

Tesla is also expanding to other regions of the United States, particularly in Arizona and California. However, the Texas expansion is a priority currently, as it is the only region where Tesla has received approval to operate passenger rides in a driverless setting in the country.

Elon Musk confirms awesome new features at Tesla Diner Supercharger

More details continue to be revealed about the Tesla Supercharger Diner as its opening seems to be imminent.

Elon Musk has confirmed a few new features that will be present at the Tesla Diner Supercharger in Los Angeles.

Musk confirmed these two new details as he revealed he recently ate at the Supercharger Diner. We also recently confirmed a few menu items as a soft launch has already occurred, and a public launch date appears to be within reach.

The new features were revealed by Tesla Joy on X. We shared the details, and Musk confirmed that these are, in fact, features of the Diner that Tesla owners will be able to enjoy.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think

The Diner is not exclusive to Tesla owners, but these two features do require a Tesla for compatibility purposes.

Order Food from Your Car

As you pull into the Supercharger Diner, you can order any food item you want, including burgers, wings, fries, shakes, cookies, and more, directly from your vehicle.

A prompt will likely appear that will open a menu to the Supercharger Diner, allowing you to order food. An employee will bring the food out, that is, if Tesla decides to continue with a true and traditional 50s diner theme.

We get it, it’s not a groundbreaking feature. It’s still cool, convenient, and another advantage to visit the diner as a Tesla owner.

Movie Screen Audio Will Sync to Your Tesla

There are two massive movie screens that will play various entertainment options during your visit to the Supercharger Diner. There have been movie clips and even SpaceX launch highlights playing during recent drone flyovers at the location on Santa Monica Boulevard.

Instead of having to open your windows to hear the content on the screen, it will instead sync the audio and play directly in your vehicle through your car stereo speakers.

The Supercharger Diner has also appeared on the Tesla app for the first time, and is currently showing 80 stalls at the location:

Although the stalls are not yet active, the culmination of all the details we’ve learned over the past week about the Diner only points to one thing: an imminent grand opening.

Tesla has not yet confirmed a date for the Supercharger Diner’s opening, and Los Angeles building and construction permits also do not state a specific target date for opening.

It seems as if Tesla will reveal the date itself, potentially in the coming week, as it will report earnings on Wednesday, July 23.

Tesla Supercharger Diner food menu gets a sneak peek as construction closes out

What are you ordering at the Tesla Diner?

The Tesla Supercharger Diner in Los Angeles is nearing completion as construction appears to be winding down significantly. However, the more minor details, such as what the company will serve at its 50s-style diner for food, are starting to be revealed.

Tesla’s Supercharger Diner is set to open soon, seven years after CEO Elon Musk first drafted the idea in a post on X in 2018. Musk has largely come through on most of what he envisioned for the project: the diner, the massive movie screens, and the intended vibe are all present, thanks to the aerial and ground footage shared on social media.

We already know the Diner will be open 24/7, based on decals placed on the front door of the restaurant that were shared earlier this week. We assume that Tesla Optimus will come into play for these long and uninterrupted hours.

The Tesla Diner is basically finished—here’s what it looks like

As far as the food, Tesla does have an email also printed on the front door of the Diner, but we did not receive any response back (yet) about what cuisine it will be offering. We figured it would be nothing fancy and it would be typical diner staples: burgers, fries, wings, milkshakes, etc.

According to pictures taken by @Tesla_lighting_, which were shared by Not a Tesla App, the food will be just that: quick and affordable meals that diners do well. It’s nothing crazy, just typical staples you’d find at any diner, just with a Tesla twist:

As the food menu is finalized, we will be sure to share any details Tesla provides, including a full list of what will be served and its prices.

Additionally, the entire property appears to be nearing its final construction stages, and it seems it may even be nearing completion. The movie screens are already up and showing videos of things like SpaceX launches.

There are many cars already using the Superchargers at the restaurant, and employees inside the facility look to be putting the finishing touches on the interior.

It’s almost reminiscent of a Tesla version of a Buc-ee’s, a southern staple convenience store that offers much more than a traditional gas station. Of course, Tesla’s version is futuristic and more catered to the company’s image, but the idea is the same.

It’s a one-stop shop for anything you’d need to recharge as a Tesla owner. Los Angeles building permits have not yet revealed the date for the restaurant’s initial operation, but Tesla may have its eye on a target date that will likely be announced during next week’s Earnings Call.
