SpaceX set for Falcon Heavy triple booster landing, hottest center core reentry yet

Falcon Heavy center core B1055 successfully landed aboard drone ship OCISLY after a record-breaking reentry. Here's to hoping that B1057 can repeat the feat. ? (SpaceX)

SpaceX’s third Falcon Heavy launch is ready to wow crowds once more with a synchronized side booster landing at Cape Canaveral and a center core recovery attempt more than 1200 km (750 mi) off the coast of Florida.

Based on the fact that Falcon Heavy’s STP-2 center core (B1057) is set to smash SpaceX’s current record for drone ship downrange distance, chances are good that B1057 will separate from the upper stage and payload traveling faster and higher than any recoverable Falcon booster before it. In short, the fresh Block 5 booster will likely be subjected to the most extreme (hottest) atmospheric reentry a SpaceX booster has ever experienced before a serious recover attempt. Thankfully, the earliest the booster can be expected to fly again is H2 2020, giving SpaceX at least a full year for a cautious, careful refurbishment.

Weather and rocket pending, Falcon Heavy Flight 3 will lift off with the Department of Defense’s (DoD) Space Test Program-2 (STP-2) mission as early as 8:30 pm PDT (11:30 pm EDT, 03:30 UTC) on June 24th. Around 2.5 minutes after liftoff, both side boosters will deploy from the center core/upper stage stack, flip around, and burn hard to entirely cancel out their eastbound momentum, picking up speed as they head back to the Florida coast.

After a leisurely 6-minute coast and reentry burn, the booster pair are set to land at SpaceX’s Landing Zones 1 and 2 roughly 8.5 minutes after launch. Pictured below (with the same boosters, no less), B1052 and B1053 will hopefully replicate the simultaneous landings that followed their picture-perfect April 11th launch debut. Despite being the first flight-proven SpaceX boosters to launch as part of a US military mission (STP-2), both boosters will also simultaneously tie SpaceX’s current record for Block 5 booster turnaround (74 days), although the company’s overall record (71 days) still stands.

Meanwhile, STP-2’s fresh Falcon Heavy Block 5 center core – B1057 – will still be soaring above Earth at hypersonic speeds and high altitudes after its side booster companions have successfully come to a rest. Incredibly, the booster’s absolutely critical reentry burn – used to quite literally cushion the blow and minimize reentry heating with the rocket’s engine exhaust – will start at T+8:53 after liftoff. A full 2.5 minutes later (T+11:21), center core B1057 will attempt to land aboard drone ship Of Course I Still Love You, stationed ~1240 km (750 mi) off the coast of Florida.

For reference, Falcon Heavy Flight 2’s Block 5 center core landed aboard OCISLY around T+9:50 after launch, meaning that STP-2’s center core will be in the air – sans any sort of boostback or altitude-raising burn – for a solid 90 extra seconds – 15% longer. To get that extra flight time, B1057 will have to be traveling significantly faster and reach a much higher altitude than its predecessor. In short, B1057 will likely experience the most intense reentry conditions a Falcon booster has ever been subjected to. The current record-holder, B1055, separated from the upper stage and payload 100 km (62 mi) above the Atlantic while traveling nearly ~3 km/s (1.9 mi/s, Mach 8.8).

Falcon Heavy center core B1055 gently landed aboard drone ship OCISLY after its record-breaking recovery. With any luck, B1057 will be similarly successful but will be spared the fate of toppling over at sea. (SpaceX)

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.

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.
