SpaceX rocket ready for second reusability record, Starlink launch attempt
One of SpaceX’s first upgraded Falcon 9 Block 5 boosters is ready for its second attempt to set a reusability record after its March 15th Starlink launch attempt aborted at the very last second.
Now scheduled to send SpaceX’s sixth batch of 60 Starlink satellites into orbit no earlier than (NET) 8:16 am EDT (12:16 UTC), March 18th, the mission will be Falcon 9 booster B1048’s fifth. Just four months ago, the booster successfully launched the first 60 upgraded Starlink v1.0 satellites, also becoming the second SpaceX rocket to fly four times. While B1049 – B1048’s predecessor – was first to reach the four-flight milestone in May 2019, B1048 is now on track to take the next leap forward for Falcon 9 reusability.
First noted shortly after the abort on SpaceX’s March 15th launch webcast, the company later clarified that what could have been attributed to hardware failure was likely just an issue with software or sensors. Milliseconds before liftoff, Falcon 9’s autonomous flight computer seemingly didn’t like what it saw while interpreting the telemetry flowing in from the ignition of B1048’s nine Merlin 1D engines. Whatever the specific trouble, Falcon 9 believed that one or several of those Merlin 1D engines were producing more thrust than they should.
While likely oversimplifying what is a spectacularly complex logic system, the flight computers that control Falcon launch vehicles from T-1 minute to mission completion have to treat the messy uncertainty of reality through a black and white lens. Lacking the ability to heuristically interpret the data they process, the computers instead rely on algorithms that filter thousands of channels of telemetry into a handful of simple categories. If that data aligns with the computer’s expectations, things are okay. If the data doesn’t agree with the plan, things are not okay. There are, of course, many more levels of complexity, but the concept of operations remains mostly the same.
However, the telemetry itself is also a potential point of failure – bad data could lead the flight computer astray, concluding that things are okay when they aren’t or vice versa. To handle that potential failure mode, SpaceX relies on multiple strings of telemetry (and even multiple computers), all gathering and analyzing the same things simultaneously. If one of several redundant sensors starts to disagree with its brethren, reporting different data back to Falcon 9’s flight computers, it’s apparent that the sensor – not the thing it’s measuring – is likely at fault. Still, out of an abundance of caution, SpaceX avionics typically treat most “out-of-family” sensor readings as reason enough to delay or fully abort a launch. When a launch delay can be little more than an annoyance with a negligible cost, it’s almost universally better to be safe than sorry.
With Falcon 9 B1048’s March 15th false start, the rocket’s computer appears to have received conflicting readings from the same family (or families) of engine thrust sensors. While, as noted above, the fault almost certainly lay in an engine sensor or two and not in the engines themselves, the flight computer chose caution over expedience and halted the launch milliseconds before it would have otherwise commanded clamp release and lifted off.
Confirmed by SpaceX delaying the Starlink V1 L5 mission by just three days, the issue was almost certainly software or sensor-related. Given that SpaceX continues to push the envelope of launch vehicle reusability, it’s honestly more surprising that aborts like these aren’t more common. Instead, the reality is that Falcon 9 Block 5 – aside from delays from the occasional upper stage fault – almost never suffers hardware-related aborts when compared to the rocket’s prior iterations.
Featuring the second-ever flight-proven Falcon payload fairing, Falcon 9 B1048 will hopefully become the first SpaceX rocket to complete five orbital-class launches and landings. With more than a little luck, there’s also a smaller chance that the mission could mark the first time SpaceX successfully catches both fairing halves with twin ships Ms. Tree and Ms. Chief.
Tune in for SpaceX’s second Starlink V1 L5 launch attempt around 8am EDT (12:00 UTC) to catch the potentially record-breaking launch and landing live.

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 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
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.
🚨 BREAKING: Tesla delivered 480,126 vehicles in Q2, ANNIHILATING Wall Street expectations of 406,000. Production was reported at 451,758.
Deliveries:
Model 3/Y: 467,762
Other Models: 12,364Production:

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.
