SpaceX highlights Crew Dragon SuperDraco thrusters as explosion investigation nears end

SpaceX has published a highlight reel touting “over 700 tests” of Crew Dragon’s SuperDraco abort thrusters at the same time as the company is about to close a failure investigation into a Dragon capsule’s April explosion, pinned primarily on abort-related hardware.

According to a September 6th meeting of NASA’s Aerospace Safety Advisory Panel (ASAP), SpaceX has nearly completed the ‘fault tree’ of Crew Dragon’s explosion, a term used to describe the process of analyzing telemetry and ruling out all possible failure modes. Once that tree is complete, the investigation can be finalized and SpaceX can implement all hardware and software changes needed to prevent similar failures from reoccurring. For the time being, this means that a 2019 launch of SpaceX’s inaugural crewed Dragon is almost certainly not in the cards, although early 2020 is still looking promising.

On April 20th, SpaceX was extremely quick to acknowledge that an anomaly had occurred during a planned static fire of flight-proven Crew Dragon capsule C201, recovered just one month prior after a flawless orbital launch debut. Soon after, an extremely low-quality video of a livestream of the static fire attempt was leaked, revealing that the capsule suffered a catastrophic explosion just moments before the ignition of its eight SuperDraco thrusters.

Incredibly, one of Crew Dragon C201’s SuperDraco ‘powerpacks’ (a pair of engines) was not only recovered intact after the explosion but static-fired at SpaceX’s McGregor, TX test facilities. A bit less than three months after the explosion, SpaceX and NASA officials hosted a press conference in July 2019 to discuss preliminary results from their joint Crew Dragon failure investigation. Some work remained to rule out other possibilities but NASA and SpaceX were confident enough to conclude that an exotic interaction between SuperDraco propellant and a leaky titanium valve likely triggered the explosion.

According to ASAP, SpaceX and NASA still have work to do before the investigation can be concluded, describing it as “nearly complete”. Additionally, the ASAP meeting continued what feels like an increasingly myopic focus on SpaceX’s carbon overwrapped pressure vessels (COPVs), used to store high-pressure helium on Falcon 9 and Heavy. COPVs have been partial causes of both of Falcon 9’s two operational failures, explaining NASA’s apparent prioritization of its certification.

Unspecified issues with parachutes were also raised for both Commercial Crew spacecraft, continuing a years-long trend of parachutes and COPVs taking up the majority of ASAP’s attention in public meetings. Boeing and SpaceX continue to test their parachute systems, both well into dozens of distinct tests after something like two years of concerted attempts to satisfy NASA requirements.

SpaceX has already demonstrated a successful orbital launch, reentry, parachute deployment, and splashdown during Crew Dragon’s March 2019 Demo-1 launch, as well as 18 successful Cargo Dragon parachute recoveries in the last seven years. Cargo Dragon did suffer one anomalous splashdown in 2018, but its partially redundant set of chutes still permitted a gentle and intact recovery.

Nevertheless, it appears that SpaceX and Boeing will have to continue performing parachute tests for the indefinite future. Boeing’s next milestone – an uncrewed orbital test flight (OTF) comparable to SpaceX’s Demo-1 mission – is expected to launch no earlier than October 28th according to Russian space industry sources. SpaceX’s next Crew Dragon milestone will be the spacecraft’s in-flight abort (IFA) test, scheduled no earlier than November 2019.

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.

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.
