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.

SpaceX Starship just nailed something it’s never done before

SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.

Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.

Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.


Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”

Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.

SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.

Tesla’s Supercharger Diner probably just secured more locations

Published

Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.

The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.

Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.

Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.

Tesla makes major change at Supercharger Diner amid epic demand

Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.

Tesla short sellers win big after shares fall after earnings

Tesla short sellers won big following the company’s massive fall on Wall Street after it reported subpar Earnings on Wednesday.

Tesla short sellers collected about $4.12 billion in single-day profits on Thursday, according to BloombergShares fell as much as 15 percent during Thursday’s session. It closed as one of the worst days for Tesla on Wall Street in the past three years.

Investors sold off the stock after Tesla said it would aggressively direct its spending toward AI and its Optimus robot project. The company had record revenues, which were driven by one of the strongest quarters in terms of vehicle deliveries in company history.

However, it missed EPS estimates by reporting just $0.33, a far cry from the $0.53 analysts expected.

S3 Partners reported that about 3 percent of Tesla’s outstanding stock is sold short. Managing Director at S3, Ihor Dusaniwsky, provided the short seller’s potential profit, as well as another figure: shorts have likely had paper gains of $8.92 billion this year, as Tesla shares are down 30 percent in 2026.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Tesla has burned short sellers many times in the past, but the company’s latest Earnings Call was a chance for those skeptics to taste some payback. Although the company gave some very transparent information regarding future projects, the rollout of Robotaxi, Optimus, and Semi, many investors took their profits on Thursday.

Notable short sellers like Michael Burry have been transparent about their skepticism around Tesla shares. Burry just revealed three weeks ago that he had opened up a new short on the stock, stating he shorted Tesla shares at $416.22. “Happy it jumped back to this level,” he said in a blog post.

At the time of publication, Tesla shares were down about 3 percent and the stock was trading at $309.92.
