SpaceX Starship’s Raptor engine test facilities are about to get a big upgrade, says Elon Musk
According to CEO Elon Musk, SpaceX’s Starship and Super Heavy rockets are about to get a new test stand that will enable additional and more useful static fire tests of their Raptor engines.
These modifications could reportedly lead to a simplified engine design and will generally expand SpaceX’s ability to rapidly acceptance-test a huge number of Raptors – a necessity given that each Starship/Super Heavy pair will need up to 43 engines.
Musk’s additional insight came by way of a tweet response to an article published today on NASASpaceflight.com, discussing SpaceX’s recently-unearthed plans to reactivate a test stand that hasn’t seen use in almost half a decade. Known as the tripod stand, the large concrete structure was originally built in the 1990s by Beal Aerospace, a now-defunct spaceflight startup, and came under SpaceX ownership when the company bought the McGregor, Texas facilities in 2003.
SpaceX repurposed the stand to static fire Falcon 9 boosters for a number of years, eventually replacing it with a ground-level installation in 2015 that has since been used to test more than 60 Falcon 9 (and Heavy) boosters. It’s not a huge surprise that SpaceX decided to make the change, given that the tripod stand necessarily placed Falcon boosters several hundred feet off the ground, making what was already a challenge even more arduous (and dangerous) for workers.
NASASpaceflight.com also notes that the stand produced far more noise pollution, encouraging SpaceX to move the replacement stand partially underground.
After four years of inactivity, NASASpaceflight.com photos show that SpaceX is well into the process of refurbishing McGregor’s tripod stand. This time, Musk says it will be modified to support vertical Raptor engine testing, likely requiring a new custom mount and new liquid methane and oxygen propellant farms.
By far the most interesting detail to come out of this development is Musk’s indication that moving Raptor static fires to a vertical stand could actually allow SpaceX to simplify the engine’s design by creating more flight-like test conditions (and thus better data). At the moment, all Raptor acceptance testing is done on a separate test stand located elsewhere at SpaceX’s McGregor facilities. Those stands are horizontal, an engineering decision likely motivated by their relatively cheap and fast construction thanks to sidestepping the need for large, water-cooled thrust diverters.
SpaceX does all of its Merlin Vacuum, Merlin 1D, Falcon 9 booster, and upper stage static fire testing on vertical stands at its McGregor facilities, with Raptor’s horizontal stands being the only exception to the rule. As such, it was likely just a matter of time before SpaceX replaced the horizontal Raptor facilities with vertical stands. Given that SpaceX plans to modify an entirely separate stand to support vertical testing, it’s likely that the company will modify the existing stands to support vertical testing as soon as the tripod stand is up and running.
For Falcon 9 and Heavy, SpaceX has relied on a total of five main engine/vehicle test stands: two for Merlin 1D, one for MVac, one for boosters, and one for upper stages. SpaceX builds engines and rockets in Hawthorne, tests every engine separately in Texas, returns them to Hawthorne, installs them on their respective booster/upper stage, and tests those stages in McGregor before they are shipped to their launch site.
Although that sounds undeniably arduous, the four stands pictured above (plus the F9 booster stand further up) have managed to support the entirety of SpaceX’s 82 launches. A new upper stage test stand is being built, but it has yet to be completed and is only necessary because Falcon 9 upper stages are expendable. According to SpaceX planning documents, Starship and Super Heavy will only perform static fire testing at the launch site. As such, something like the cluster of four Merlin stands above could very likely support the production and testing of 100-200+ Raptor engines annually, enough to build numerous boosters and ships.
SpaceX moves fast, so stay tuned for updates as work continues on the tripod stand and paves the way for even more significant changes at SpaceX’s McGregor, Texas test 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:
🚨 We could see Tesla’s response to Waymo’s expansion in Austin very soon
Based on Tesla’s expansion last time, it’s safe to assume they can go to any area of Austin whenever they choose
It’s not a coincidence they chose, well, you know, the shape they did 🤣 https://t.co/xB92SQ1ntC

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.

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.
