SpaceX is set for Falcon 9’s first orbital launch in more than three months. Known as Starlink-1, the mission will launch the company’s heaviest satellite payload ever and feature an impressive array of Falcon 9 booster and fairing reusability milestones.

Prior to Falcon 9 going vertical on the launch pad, SpaceX technicians had to construct and encapsulate a massive stack of 60 Starlink satellites, each weighing more than 260 kg (570 lb) apiece. This is the second time SpaceX has launched sixty of the advanced spacecraft, although the satellites that will launch on Starlink-1 feature a number of upgrades and refinements not present on the Starlink v0.9 satellites that launched in May 2019.

Without an identical angle from the Starlink v0.9 mission to compare against, it’s difficult to immediately point out visual differences between v0.9 and v1.0 spacecraft. Still, there are some clear general changes. Most notably, SpaceX appears to have dramatically reduced the area of shiny, metallic surfaces. Additionally, the small downward-facing dishes just left of center in the above image were not obviously present on Starlink v0.9 satellites or SpaceX’s official renders.

Those new dishes could be traditional dish antennas meant to serve as a more basic telemetry, tracking, and command (TTC) communications link for ground controllers. They could even be a prototype of Starlink’s planned inter-satellite laser data links. Regardless, it’s obvious that SpaceX is continuing its preferred cycle of rapid prototyping, flight-testing, and data-based refinement with Starlink.

SpaceX is also focused on dramatically lowering the albedo (reflectivity) of Starlink satellites and working closely with the astronomy and astrophysics communities to minimize any disruption the spacecraft might cause for scientific observations of the night sky. For any part that will be ground-facing during routine operations, this likely involves replacing shiny surfaces with matte finishes and adding dark or non-reflective coatings/insulation where possible, among other potential tweaks.

The more milestones, the merrier

Beyond the many apparent satellite upgrades Starlink-1 is set to debut, the mission will also mark no less than three (or possibly even four) reusability milestones. Falcon 9 booster B1048 has been selected by SpaceX to support Starlink-1 and has already completed three successful orbital-class missions since it debuted in July 2018. Assuming all goes well, B1048 will thus become the first SpaceX booster to launch (and land) four times, an excellent – if increasingly unsurprising – step forward for Falcon 9’s Block 5 upgrade. Falcon 9 B1048 will attempt its fourth landing – this time on drone ship Of Course I Still Love You (OCISLY) – shortly after launch.

Designed to enable up to 10 reuses of each Falcon booster, the successful completion of Starlink-1 will place Block 5 just one reuse away from the halfway point to proving its 10-reuse design. While Block 5 has yet to materialize any tangible improvements in booster turnaround time, an imminent ramp in Starlink launch cadence will hopefully give SpaceX plenty of opportunities to start making progress on that front.

Starlink-1 is also set to mark the inaugural launch of a flight-proven Falcon 9 fairing, essentially putting a bow on the bulk of SpaceX’s challenging fairing recovery and reusability development. Unintuitively, Starlink-1’s fairing previously supported Falcon Heavy Block 5’s April 209 launch debut, meaning that both halves traveled both faster and higher than any halves that previously attempted recovery.

Simultaneously, both halves splashed down in the Atlantic Ocean with no attempt to catch them, meaning that SpaceX has apparently successfully refurbished the fairings despite the fact that their recovery was more or less the worst-case scenario.

Last but not least, Starlink-1 will also mark the first time SpaceX’s just-finished fairing recovery ship GO Ms. Chief attempts to catch a Falcon 9 fairing, as well as the first time two fairing recovery ships – Ms. Tree & Ms. Chief – attempt to catch both halves of a Falcon fairing after launch. The twin recovery vessels departed Port Canaveral, Florida a few days ago and arrived at their recovery point ~750 km (460 mi) downrange on November 10th.

Finally, thanks to the fact that Falcon 9’s fairing is flight-proven, Starlink-1 will additionally feature the first attempted recovery (catch or splashdown) of a flight-proven Falcon fairing. SpaceX could scarcely fit in another milestone if it wanted to go out of its way to do so.

Falcon 9 is scheduled to lift off no earlier than 9:56 am ET (14:56 UTC), November 11th. Weather is 80% GO and SpaceX has a backup launch window around the same time on November 12th with a 70%-favorable weather forecast.

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

Published

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.
