In spite of tentative plans for preservation, SpaceX has fully scrapped the wreckage of the first high-altitude Starship prototype, clearing the landing zone it impacted for its successor’s imminent launch debut.

Known as serial number 8 or SN8, the Starship prototype was the first of any kind to fly beyond 150 meters (~500 ft), reaching an altitude of 12.5 km (~7.8 mi) on December 9th during its breathtaking launch debut. In an unexpected twist, SpaceX kept Starship SN8’s thrust to weight ratio as low as possible, stretching what could have been a two or three-minute test into an almost seven-minute ordeal with three consecutive Raptor engine cutoffs during the ascent.

At apogee, SN8 used cold gas thrusters to flip into a belly-down orientation and free-fell ~95% of the way back to Earth before igniting two of its three Raptor engines, performing a wild powered flip back into a vertical landing position and nearly securing a soft landing. Unfortunately, around 10-20 seconds before that planned landing, what Musk later described as low methane header tank pressure starved the Starship’s engines of fuel and more or less cut all appreciable thrust, causing SN8 to reach its landing zone traveling about 40 m/s (~90 mph) too fast. The rocket impacted the concrete pad, crumpled, and exploded.

By all accounts, success was one of the less likely outcomes SpaceX expected from SN8’s high-altitude debut, with Musk himself estimating the odds of total success to be just 33%. Additionally, Starship SN8 effectively made it all the way to a low-speed landing regime that Starships SN5 and SN6 all but flawlessly demonstrated with back-to-back 150m hops and landings in August and September 2020.

In other words, despite the explosive end, SN8’s high-altitude launch debut was a spectacular success for SpaceX’s Starship program – possibly even preferable to a perfect landing given that it uncovered an unexpected issue with fuel tank pressurization. Beyond the landing failure, the Starship checked every single box on SpaceX’s test flight list, successfully debuting multiple Raptors, demonstrating multiple in-flight engine shutdowns and engine relights; proving that an unprecedented ‘skydiver-style’ landing maneuver is possible and viable; and successfully testing Starship’s ability to control itself in that bellyflop orientation with thrusters and four massive flaps.

Speaking in a recent interview with Ars Technica, in the words of pragmatic SpaceX COO and President Gwynne Shotwell, SN8’s launch debut “de-risked [the Starship] program pretty massively.” According to Musk, SpaceX engineers were quickly able to determine why Starship SN8’s methane header tank was unable to maintain the fuel flow (pressure) needed for Raptor’s landing burn(s) and quickly implemented a solution.

Thanks to a quick, temporary fix, Starship SN9’s own 12.5 km launch debut remains on track to despite SN8’s failed landing. (NASASpaceflight – bocachicagal)

Instead of pressurizing autogenously with methane gas, Starship SN9 will use helium to pressurize its fuel header tank, serving as a temporary fix while SpaceX determines what changes need to be made to get rid of that helium crutch. Landing pad now cleared of Starship remains and SN8’s impact crater more or less repaired, the only thing standing between Starship SN9 and its own 12.5 km launch debut is a triple-Raptor static fire test. Originally expected as early as January 4th, SpaceX never made it more than a few minutes into the attempt, while a backup window on January 5th was canceled later that evening. The test could now occur no earlier than (NET) Wednesday, January 6th.

Although SpaceX couldn’t fully salvage SN8’s nosecone wreckage, it did snag a mostly intact flap before scrapping the rest. (NASASpaceflight – bocachicagal)

Thankfully, although SpaceX was unable to save the entirety of Starship SN8’s wrecked nose section, the company did manage to extract a largely intact nose flap. The rest of the remains were scrapped on site and trucked away but it’s possible that certain significant components of SN8 – particularly the recovered flap – will eventually find themselves on display at one or more SpaceX facilities.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.

Tesla crushes Wall Street expectations, beats delivery estimates by over 15 percent

Published

on

Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.

Tesla reported it delivered 467,762  Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.

The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.

Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.

For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.

Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.

Tesla sends production Cybercab with no steering wheel, pedals to on-road testing

The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.

Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.
