SpaceX has completed its 52nd successful Falcon 9 launch in 52 weeks, sustaining an average cadence of one launch per week for a full 12 months.

Simultaneously, the Starlink 4-2 rideshare mission set a new record for Falcon 9 booster reuse, marked SpaceX’s 150th consecutively successful launch, and was one of the most complex commercial launches it has ever performed.

In addition to 34 new Starlink V1.5 satellites that joined almost 3000 other working SpaceX spacecraft in orbit, Starlink 4-2 deployed the company’s largest rideshare payload yet – AST SpaceMobile’s 1.5-ton (~3300 lb) BlueWalker 3 communications satellite.

Falcon 9 lifted off on schedule with the combined 12-ton (~26,500 lb) payload safely secured inside its composite payload fairing at 9:20 pm EDT (01:20 UTC) on Saturday, September 10th. Tasked with lifting the rocket’s expendable upper stage, recoverable fairing, and payload most of the way out of Earth’s atmosphere was Falcon 9 booster B1058, a nine-engine first stage that debuted by launching two NASA astronauts in May 2020.

28 months later, B1058 lifted off with Starlink 4-2 and BlueWalker 3 on its 14th spaceflight and orbital-class launch, breaking Falcon 9’s booster reuse record. The rocket performed no differently than it had every time previously, burning for a bit less than three minutes before deploying the upper stage and returning to Earth. About nine minutes after liftoff, B1058 safely touched down on drone ship A Shortfall Of Gravitas (ASOG), likely setting the booster up to break its own record before the end of 2022. With 13 launches already under their belts, boosters B1051 and B1060 will likely follow B1058 past the same 14-flight milestone in the near future.

Once free from the booster, Falcon 9’s expendable upper stage kicked off SpaceX’s most complex commercial launch ever. Measuring about six minutes long, the first and longest burn brought the second stage and payload into an elliptical orbit a few hundred kilometers above Earth’s surface. A second burn followed about 45 minutes after liftoff, raising the low end of that ellipse to deploy BlueWalker 3 into a circular orbit around 500 kilometers (~310 mi). Using a massive antenna, AST SpaceMobile’s first large satellite prototype will eventually attempt to directly communicate with mobile phones to provide a level of connectivity equivalent to 5G/LTE – all from space.

Once free of its rideshare payload, the focus shifted to Starlink. In theory, SpaceX could have taken the easy way out and significantly simplified the mission by deploying all 34 satellites at the same altitude as BlueWalker 3, simultaneously allowing them to reach their operational 540-kilometer (~336 mi) orbits in days instead of months. Instead, SpaceX pursued an exceptionally complex mission requiring five burns from Falcon 9’s upper stage.

After deploying BlueWalker 3, Falcon 9 S2 lowered one end of its orbit at around T+67 minutes, followed by a fourth burn to lower the other end almost two hours after liftoff. The upper stage then spun up end over end and eventually released all 34 Starlink satellites at an altitude of ~335 kilometers (~208 mi), where debris and faulty satellites will take days – rather than years – to reenter Earth’s atmosphere and burn up.

While SpaceX doesn’t confirm post-payload operations, Falcon 9 S2 was also scheduled to perform a fifth and final burn to quickly deorbit itself, ensuring that the mission only produced five pieces of benign debris. At their very low orbits, those five pieces (four ‘tensioning rods’ and the BlueWalker 3 payload adapter) will pose next to no threat to other spacecraft or rockets and should reenter within a few weeks.

Starlink 4-2 was SpaceX’s 52nd successful Falcon 9 launch since September 14th, 2021, meaning that the company has technically already achieved CEO Elon Musk’s goal of 52 launches in one year – albeit not a calendar year. Perhaps even more impressive, the mission was SpaceX’s 150th consecutively successful Falcon launch. No other single rocket (Falcon 9) or rocket family (Falcon) has launched more times in a row without failure.

Finally, Starlink 4-2 was SpaceX’s 42nd launch of 2022. If the company continues its average cadence over the last three months, it could end 2022 having completed more than 60 Falcon launches in one calendar year.

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.
