Several months after the first prototype was spotted floating around Starbase, SpaceX has finished assembling a tank designed to put upgraded Starship domes to the test.

Known only as “EDOME” per a tracking label taped to its side, the prototype looks fairly ordinary from the outside and could easily be mistaken for just the latest in a long line of nine ‘test tanks’ SpaceX has already built, tested, and sometimes destroyed. However, under its ordinary exterior of nine-meter (30 ft) wide steel rings and stringers, there are two tank domes that represent a significant design departure from the dozens of domes SpaceX has built and tested over the last two years. Much like a new nosecone design that SpaceX only began testing for the first time a matter of days ago, a large part of the dome redesign was focused on making them much easier to build.

Work on the first upgraded Starship nose prototypes began in earnest around the turn of the new year. Starship’s upgraded domes took a bit longer, with a completed prototype appearing for the first time in mid-March. To an extent, the new dome went even further than SpaceX’s slightly more modest nose redesign, drastically simplifying the structure into just one main component. Whereas the nose redesign simplified nose assembly from five to three different stacked sets of welded ‘gores,’ or tapering slices of metal, SpaceX’s dome redesign appears to have more or less reduced the number of stacked sections from three to one.

The new dome design should only require 18 ‘gores’ and one small cap, compared to the roughly 40 different pieces and three ‘stacks’ needed for each older dome. Thanks to the new dome’s more hemispherical shape, SpaceX has also managed to improve the efficiency of the design while still making it far easier to assemble. Despite being significantly more compact than the old design, the new dome should still be able to hold roughly the same amount of propellant as the old dome.

SpaceX finished assembling the first “EDOME” test tank sometime in late May or early June. The tank is comprised of two upgraded domes and five steel rings and measures nine meters (~30 ft) wide and tall. Both domes have been fitted with a single pipe: one for a set of vent valves and the other for filling or draining the tank of liquid nitrogen (LN2).

Following the tank’s June 8th arrival at SpaceX’s Starbase launch and test facilities, it likely won’t be long before the tank kicks off its first (and probably only) test campaign. Like past test tanks, SpaceX may start with a pneumatic or water test to check for leaks and ensure basic structural integrity, or it will move directly into cryogenic pressure/stress testing with liquid nitrogen. While the main goal of any test tank is to learn about new hardware, the best-case outcome would either be the total survival of the tank (i.e. too sturdy to be destroyed with the available test equipment) or its destruction well past the maximum pressure it was designed to survive. As of 2020, Starship tanks were expected to operate around 6.5 bar (~95 psi) and designed to survive up to 8-8.5 bar (~115-125 psi).

Starship S24 is expected to return to Starbase’s build site for final assembly on Thursday, June 9th, freeing up SpaceX to test the EDOME tank during one or more 12-hour test windows it has requested on June 13th, 14th, and 15th.

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 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 door handle saga gets its latest chapter and a big change is coming

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.

Published

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.
