SpaceX preps Texas Starship’s second tank dome for installation in latest milestone
During an August 4th visit to SpaceX’s Boca Chica Starship build site, CEO Elon Musk captured and shared photos showing technicians carefully flipping the second of three propellant tank domes destined for installation inside the company’s South Texas orbital Starship prototype.
This is the latest visible step towards the completion of one of SpaceX’s two “Mk 1” Starships, said by Elon Musk to be the first orbit-capable prototypes. Per recent tweets, either or both of the prototypes – being built concurrently at separate sites in Florida and Texas – could be ready for their first flight tests as early as September or October 2019.
Set to be powered by up to three sea-level (SL) Raptors and three vacuum-optimized Raptors (RVacs), Musk has stated that SpaceX’s first two orbital Starship prototypes will likely begin flight testing with just the three SL engines installed. Recently, the SpaceX CEO did, however, indicate that development of Raptor’s vacuum variant – postponed as of a September 2018 update – had been reprioritized and said that it could actually be ready sooner than later.
Raptor Vacuum will have a significantly larger nozzle compared to the sea level engine it will be based on. According to Musk, RaptorVac will have a nozzle diameter of roughly 2.8m (9.2 ft), while the SL Raptor features a ~1.3m (4.2 ft)-diameter nozzle. With a larger diameter nozzle, a chemical rocket engine can technically generate more thrust and is significantly more efficient due to an increased expansion ratio, meaning the difference in the diameter of the nozzle exit and combustion chamber throat.
In the very simplest sense, this efficiency and thrust increase comes from the fact that a longer nozzle allows the exiting gas (reaction mass) to reach a higher velocity, thus conveying more momentum onto the rocket it is propelling.


Starship’s Raptor engines, of course, use liquid methane as fuel and liquid oxygen as their oxidizer. According to SpaceX, fully fueling a combined Super Heavy and Starship stack will require an incredible ~5000 tons (11 million pounds) of propellant – ~1500 tons for Starship and ~3500 tons for Super Heavy.
To contain such a huge amount of fuel and oxidizer, Starship (and Super Heavy) must effectively be turned into extremely mass-efficient pressure vessels, capable of supporting something like 20 kilograms of propellant with every kilogram of rocket structure.

SpaceX’s installation of bulkheads in the Texas Starship prototype are thus an inherent indication that the rocket is being readied to play the role of a massive, ultra-strong pressure vessel. While sitting vertically, a fueled Starship’s tank domes will be subjected to immense pressures and forces from the sheer weight of the liquid oxygen and methane held above them.
Additionally, the rearmost dome will likely be partially or fully integrated into Starship’s thrust structure, meaning that it will simultaneously be subjected to the thrust of 3-6 Raptors (as much as 600-1200 tons of thrust) and the gravity of 300 metric tons of methane. It’s unclear if SpaceX is planning to reinforce Starship and Super Heavy tank bulkheads with structural add-ons, but it’s safe to assume that some level of reinforcement will be required.


SpaceX CEO Elon Musk’s planned August 24th presentation on Starship and Super Heavy will likely (hopefully) provide some new details on the structure and general design of the company’s advanced, next-generation rocket.

Tesla’s Supercharger Diner probably just secured more locations
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:
Tesla Diner opened exactly 1 year ago. Inspiring that futuristic places like this exist.
It’s our highest usage Supercharger in the world: 21.2 GWh delivered in a year, 1.6k sessions/day.

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 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 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.
🚨 The NHTSA denied a petition from Tesla that would have thrown out concerns regarding its door handles.
NHTSA said Tesla’s petition did not present evidence of a safety-related defect warranting an investigation. The agency said a rulemaking process would be a better strategy. pic.twitter.com/j6PzUBM1mT

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.
