SpaceX’s fifth full-scale Starship prototype could become the first to take flight just a week or so from now if a Raptor engine test goes as planned early next week.

Known as Starship serial number 5 (SN5), SpaceX teams are currently in the process of completing the installation of Raptor SN27 and preparing the massive steel rocket for its first cryogenic wet dress rehearsal and static fire tests. Delayed from July 8th and 10th, Starship SN5’s first Raptor static fire is now scheduled no earlier than ~10 am CDT (~15:00 UTC) on Monday, July 13th.

If things go well during those nominally back-to-back tests, public road closure filings show that SpaceX wanted to attempt the first full-scale Starship hop just three days later, although the recent two-day delay adds a bit of uncertainty.

The odds are good that one or both of those test periods will slip or change in the next few days and, in fact, Starship SN5’s static fire test period was delayed two days while this article was in work. SpaceX could run into road bumps that prevent the July 10th 13th wet dress rehearsal (WDR) from smoothly transitioning into a Raptor static fire attempt and any number of additional delays could beset the actual flight test throughout the flow. Along the same lines as Starhopper, currently the only vehicle to have flown under the power of a Raptor engine, Starship’s flight computer could abort the launch at almost any point prior to liftoff, up to and including Raptor ignition.

Like Falcon 9 and Falcon Heavy, Starship (and Starhopper) will ingest and interpret hundreds or thousands of channels of telemetry to determine the health of its engines for a second or two after ignition while thrust is ramping. If the Raptor or Merlin engine(s) look healthy, the rocket commands hold-down clamp release and lifts off (or, in the case of Starhopper, uses its own immense weight to prevent liftoff until Raptor is throttled up).

Thanks to an upgraded launch mount, SpaceX’s full-scale Starship prototypes have access to built-in hold-down clamps, enabling operations that are at least a bit more similar to those used for Falcon 9 and Heavy launches. Starship’s six hold-down clamps are affixed to the same structure that the ship’s six landing legs are installed on.

Perhaps the single biggest point of uncertainty with Starship’s first full-scale test flight is its somewhat mysterious landing legs – almost entirely different from Falcon 9’s well-proven four-leg design. The stubby Starship legs stow inside the ship’s engine section, swinging down and out (and potentially telescoping, albeit much less than Falcon 9) come touchdown. Based on photos of the legs, they may also feature rudimentary shock absorption mechanisms, meaning that Starship should be able to tolerate slightly rougher landings. SpaceX has likely tested Starship leg deployment extensively on the ground but beyond that assumption, they remain an unproven mystery.

Regardless, SpaceX is going to be extremely busy over the next 7-10 days with Starlink-9 scheduled to launch NET July 11th, Starship SN5’s static fire NET July 13th, Falcon 9’s ANASIS II launch scheduled NET July 14th, and a potential SN5 hop test attempt as early as July 16th (speculation).

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.

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.
