SpaceX fires up Starship booster at orbital launch pad
For the first time, SpaceX has static fired a Starship booster at its South Texas orbital launch pad, marking important milestones for both.
After months of cautious testing and multiple rounds of repairs, Super Heavy Booster 7 made it through its first Raptor tests (without causing an explosion) on August 8th, completing a pair of “spin-prime” tests with one Raptor engine. Booster 7 began testing in early April, more than four months ago. As previously discussed on Teslarati, the massive 69-meter-tall (~227 ft) rocket has had an exceptionally rocky journey to its current test campaign.
“Booster 7 first headed to the pad on March 31st and successfully completed two major cryogenic proof tests, but was severely damaged during a subsequent structural stress test. After a few weeks of repairs back at the factory, B7 rolled out to the pad a second time, completed a third cryoproof test, and returned to the factory again on May 14th, where it stayed until June 23rd.”

After several halting, minimal tests in late June and early July, Booster 7 – partially loaded with either propellant or a combination of more neutral cryogenic fluids – attempted a spin-prime test with all 33 of its Raptor 2 engines on July 11th. The mixture of gas that testing created found an unintended ignition source and violently exploded, significantly damaging parts of Super Heavy’s aft section. For the third time, SpaceX returned Booster 7 to its Starbase factory and spent another three weeks removing the rocket’s just-installed Raptor engines and repairing the damage.
On August 6th, Booster 7 rolled to the pad for the fourth time, revealing that SpaceX had only reinstalled 20 of the rocket’s maximum 33 Raptor engines. On August 8th, clearly indicative of a much more cautious second attempt at engine testing, SpaceX ‘primed’ just one of those 20 Raptors by flowing high-pressure gas through the engine to spin up its turbopumps without igniting its preburners (used to generate the gas that powers the turbopumps) or main combustion chamber.
Less than 24 hours later, SpaceX successfully kicked off another round of testing and ignited the same spin-primed engine on the first try. Super Heavy B7 survived the test without visible issue and was safely depressurized and detanked soon after. The lone Raptor engine also appeared to perform perfectly and shut down cleanly after a stable three or four-second burn.
Booster 7’s first static fire – also the second static fire test of a Super Heavy – was the first test of an upgraded Raptor 2 engine on any rocket prototype. At the cost of slightly less efficient combustion, Raptor 2 is designed to produce up to 230 tons (~510,000 lbf) of thrust – almost 25% more than Raptor 1 (185 tons or ~410,000 lbf).
With about four hours left in August 9th’s test window, which closes at 10 pm CDT (03:00 UTC), SpaceX still has time to test Starship S24, which also completed Raptor spin-prime tests on August 8th. SpaceX has an additional 10am-10pm road closure scheduled on Wednesday, August 10th.
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 Bloomberg. Shares 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.
Tesla’s long-standing saga regarding its door handles and a manual release has entered its latest chapter, and as a result, a big change is coming.
On Friday, the National Highway Traffic Safety Administration (NHTSA) denied Tesla’s petition that was seeking a defect investigation into roughly 180,000 Model 3 vehicles for an issue involving the emergency mechanical door release.

NHTSA said that Tesla’s petition did not present evidence of a safety-related defect in the door handles or their emergency releases. Instead, the agency determined that it would rather solve the issue of the lack of labeling or location of emergency mechanical door releases and the federal safety rules that govern them.
Essentially, the NHTSA wants to create and enforce rules that would require automakers to make emergency door latch releases more clearly labeled in a car. Despite a Tesla having manual door releases on all four passenger doors, many people do not know they exist or how they work.
Tesla addresses door handle complaints with simple engineering fix
In recent times, Tesla has faced some criticism involving its door handles, specifically because some occupants have reported that they are unable to exit their vehicles after losing power. The door handles on a Tesla are electronically operated, but in the event that the 12V battery dies, there is a manual release that can be used.
The NHTSA only identified a single complaint involving the mechanical door releases: a 2022 Model 3 owner said the release was concealed and unlabeled after the vehicle lost power after a front-end collision. It has also already started to create a separate rulemaking process to make emergency door-egress systems more obvious.
It should be noted that all Teslas have mechanical emergency door releases, but they are placed in various locations as the vehicles have aged and been redesigned from year to year. Refer to the safety manual for your vehicle if you have any confusion about where the emergency releases are and how they work.

SpaceX Starship Flight 13 faces wrath of the Texas skies
SpaceX pushed Starship Flight 13 to Friday, blaming weather instead of the previous engine issues.
SpaceX called off Thursday’s launch attempt of Starship Flight 13, pushing the mission to Friday because of weather tied to Tropical Storm Bertha. The company confirmed the delay on X, noting “Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won’t be possible with today’s weather conditions.”
This is the second delay for Flight 13 in two weeks. SpaceX first tried to launch the mission on July 16, but the countdown ended in an automated abort at T-0 when four of Super Heavy Booster 20’s 33 Raptor engines failed to ignite. Musk said at the time that two Raptors would need to be removed and replaced, as Teslarati reported. The company spent the following week destacking Ship 40 and Booster 20, swapping engines, and running leak checks before restacking the vehicle on Pad 2 Wednesday night, according to Spaceflight Now’s live coverage.
Unlike the engine problem, Thursday’s delay has nothing to do with the hardware. SpaceX wants clean footage of Starship’s heat shield captured from the ground as the vehicle flies through max dynamic pressure, something the storm’s cloud cover over South Texas would not allow. The company said visibility should improve for Friday’s attempt, with the same 90 minute window opening at 5:45 p.m. CT.
Flight 13 will be the second outing for the V3 versions of Starship and Super Heavy, following their debut on Flight 12 in May. The mission carries 20 production Starlink V3 satellites, the first time SpaceX has flown operational satellites rather than mass simulators on Starship. Six of those satellites are fitted with cameras to inspect the heat shield from a different angle during ascent, giving engineers a second data source beyond the ground imagery the weather is currently blocking.
Booster 20 will attempt a boostback burn and a splashdown landing burn in the Gulf of America, while Ship 40 follows a suborbital trajectory toward a landing in the Indian Ocean. The flight plan largely mirrors Flight 12, though the booster will run a more aggressive ascent burn after max Q this time, and the ship’s heat shield includes load sensing tiles meant to measure stress at the higher dynamic pressure SpaceX is targeting.
If Friday’s attempt succeeds, Flight 13 could be the last suborbital test in the program. SpaceX is already looking to push for an orbital flight on Flight 14.
