Two SpaceX Falcon 9 rockets have completed back-to-back Starlink launches less than 24 hours apart, successfully delivering 106 Starlink satellites to low Earth orbit (LEO).

Originally scheduled just a handful of hours apart, slight delays eventually saw Starlink 4-13 and Starlink 4-15 settle on 6:07 pm EDT, May 13th and 4:40 pm EDT, May 14th, respectively. Entering the final stretch, launch preparations went smoothly and both Falcon 9 rockets ultimately lifted off without a hitch.

The series began with Starlink 4-13 on Friday. SpaceX chose Falcon 9 B1063 to support the Starlink launch and the booster did its job well, wrapping up its fifth launch since November 2020 with a rare landing aboard drone ship Of Course I Still Love You (OCISLY). Since SpaceX permanently transferred OCISLY from the East Coast to the West Coast in mid-2021, the drone ship has only supported five booster recoveries. Save for an unusual East Coast Starlink launch in May 2021, Falcon 9 B1061 has also primarily been tasked with supporting SpaceX’s West Coast launch manifest. With only one older pad – Vandenberg Space Force Base’s (VSFB) SLC-4 complex – available to SpaceX, the company’s West Coast Falcon launches are also considerably rarer than its East Coast missions.

SpaceX has also taken to using the pad – which is in an optimal location to launch satellites that orbit Earth’s poles – to launch several batches of Starlink satellites into more ordinary equatorial orbits, essentially augmenting the capabilities of its two Florida launch sites.

Starlink 4-13 and 4-15 were more or less identical, in that regard; both launched 53 Starlink V1.5 satellites into LEO to continue filling out the fourth of five Starlink orbital ‘shells’ that will make up SpaceX’s first licensed constellation. Since SpaceX began Plane 4 (or Group 4) launches in November 2021, the company has now completed 15 missions that carried a total of 860 Starlink V1.5 satellites into orbit. Excluding a solar storm-related fluke that destroyed almost an entire launch worth of satellites, all but 8 remain operational in orbit. According to astronomer Jonathan McDowell’s independent tracking, about 300 Group 4 Starlink satellites have reached operational orbits, while another 500 or so are either raising their orbits or waiting for the right moment to do so.

As of May 2022, the first shell or ‘group’ of SpaceX’s first Starlink constellation has about 1500 operational Starlink satellites of a nominal 1584. If all working Group 4 satellites currently in orbit become operational, SpaceX has another ~770 satellites or 15 launches to go to complete the shell (17 to finish Shell 1 and Shell 4). If SpaceX maintains its current six-month launch cadence of one Starlink mission every ~11 days, SpaceX’s first Starlink constellation could have around 3400 working satellites in orbit and be more than three-quarters complete by the end of 2022.

SpaceX, by all appearances, fully intends to push its vehicles and workforce to the absolute limits in 2022 in a bid to complete as many as 60 orbital launches. To launch Starlink 4-15, for example, SpaceX made an unprecedented decision to debut a brand new Falcon 9 booster on the internal mission, demonstrating just how fully its customers have embraced reusability and how much the company wants to expand its fleet of Falcon 9 boosters as quickly as possible.

Following Starlink 4-13 and 4-15, SpaceX has completed 20 launches in the first 19 weeks of 2022 and has another two launches scheduled in the last two weeks of May.

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.
