In spite of tentative plans for preservation, SpaceX has fully scrapped the wreckage of the first high-altitude Starship prototype, clearing the landing zone it impacted for its successor’s imminent launch debut.

Known as serial number 8 or SN8, the Starship prototype was the first of any kind to fly beyond 150 meters (~500 ft), reaching an altitude of 12.5 km (~7.8 mi) on December 9th during its breathtaking launch debut. In an unexpected twist, SpaceX kept Starship SN8’s thrust to weight ratio as low as possible, stretching what could have been a two or three-minute test into an almost seven-minute ordeal with three consecutive Raptor engine cutoffs during the ascent.

At apogee, SN8 used cold gas thrusters to flip into a belly-down orientation and free-fell ~95% of the way back to Earth before igniting two of its three Raptor engines, performing a wild powered flip back into a vertical landing position and nearly securing a soft landing. Unfortunately, around 10-20 seconds before that planned landing, what Musk later described as low methane header tank pressure starved the Starship’s engines of fuel and more or less cut all appreciable thrust, causing SN8 to reach its landing zone traveling about 40 m/s (~90 mph) too fast. The rocket impacted the concrete pad, crumpled, and exploded.

By all accounts, success was one of the less likely outcomes SpaceX expected from SN8’s high-altitude debut, with Musk himself estimating the odds of total success to be just 33%. Additionally, Starship SN8 effectively made it all the way to a low-speed landing regime that Starships SN5 and SN6 all but flawlessly demonstrated with back-to-back 150m hops and landings in August and September 2020.

In other words, despite the explosive end, SN8’s high-altitude launch debut was a spectacular success for SpaceX’s Starship program – possibly even preferable to a perfect landing given that it uncovered an unexpected issue with fuel tank pressurization. Beyond the landing failure, the Starship checked every single box on SpaceX’s test flight list, successfully debuting multiple Raptors, demonstrating multiple in-flight engine shutdowns and engine relights; proving that an unprecedented ‘skydiver-style’ landing maneuver is possible and viable; and successfully testing Starship’s ability to control itself in that bellyflop orientation with thrusters and four massive flaps.

Speaking in a recent interview with Ars Technica, in the words of pragmatic SpaceX COO and President Gwynne Shotwell, SN8’s launch debut “de-risked [the Starship] program pretty massively.” According to Musk, SpaceX engineers were quickly able to determine why Starship SN8’s methane header tank was unable to maintain the fuel flow (pressure) needed for Raptor’s landing burn(s) and quickly implemented a solution.

Instead of pressurizing autogenously with methane gas, Starship SN9 will use helium to pressurize its fuel header tank, serving as a temporary fix while SpaceX determines what changes need to be made to get rid of that helium crutch. Landing pad now cleared of Starship remains and SN8’s impact crater more or less repaired, the only thing standing between Starship SN9 and its own 12.5 km launch debut is a triple-Raptor static fire test. Originally expected as early as January 4th, SpaceX never made it more than a few minutes into the attempt, while a backup window on January 5th was canceled later that evening. The test could now occur no earlier than (NET) Wednesday, January 6th.

Although SpaceX couldn’t fully salvage SN8’s nosecone wreckage, it did snag a mostly intact flap before scrapping the rest. (NASASpaceflight – bocachicagal)

Thankfully, although SpaceX was unable to save the entirety of Starship SN8’s wrecked nose section, the company did manage to extract a largely intact nose flap. The rest of the remains were scrapped on site and trucked away but it’s possible that certain significant components of SN8 – particularly the recovered flap – will eventually find themselves on display at one or more SpaceX facilities.

Tesla ‘Model Q’ gets bold prediction from Deutsche Bank that investors will love

Tesla’s Model Q could be on the way soon, and a new note from Deutsche Bank thinks it will contribute to Q4 deliveries.

The Tesla “Model Q” has been in the rumor mill for the company for several years, but a recent note from Wall Street firm Deutsche Bank seems to indicate that it could be on its way in the near future.

This comes as Tesla has been indicating for several quarters that its development of affordable models was “on track” for the first half of 2025. The company did not say it would unveil the vehicles in the first half, but many are anticipating that more cost-friendly models could be revealed to the public soon.

Potential affordable Tesla “Model 2/Model Q” test car spotted anew in Giga Texas

The Deutsche Bank note refers to one of the rumored affordable models as the “Model Q,” but we’ve also seen it referred to as the “Model 2,” amongst other names. Tesla has not officially coined any of its upcoming vehicles as such, but these are more of a universally accepted phrase to identify them, at least for now.

The rumors stem from sentiments regarding Tesla’s 2025 delivery projections, which are tempered as the company seeks to maintain a steady pace compared to 2023 and 2024, when it reported 1.8 million deliveries.

Deutsche Bank’s analysts believe the deliveries could be around 1.58 million, but they state this is a cautious stance that could be impacted by several things, including the potential launch of the Model Q, which they believe will make its way to market in Q4:

“Looking at the rest of the year, we maintain a cautious stance on volume calling for 1.58m vehicle deliveries (-12% YoY) vs. consensus +1.62m, with the timing of Model Q rollout as the key swing factor (we now assume only 25k in Q4). In China, Tesla will introduce the Model Y L this fall (6 inch longer wheel base allowing for larger 3-row seating with six seats).”

Interestingly, the same firm also predicted that the Model Q would launch in the first half of the year based on a note that was released in early December 2024.

Those estimations came from a reported meeting that Deutsche Bank had with Tesla late last year, where it said it aimed to launch the Model Q for less than $30,000 and aimed for it to compete with cars like the Volkswagen ID.3 and BYD Dolphin.

Tesla’s Q2 Earnings Call is slated for this Wednesday and could reveal some additional details about the affordable models.

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 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.
