SpaceX has released uncut footage of one of its most recent Falcon 9 launches and landings, including unprecedented onboard audio from the rocket through all phases of flight.

The rocket in question, Falcon 9 booster B1059, ended months of delays when it lifted off at long last on August 30th, sending a new upper stage, payload fairing, and an Argentinian Earth observation satellite on their way to orbit. Known as SAOCOM 1B, the second of a pair of synthetic aperture radar satellites launch by SpaceX deployed from Falcon 9 less than 15 minutes after liftoff, followed by two rideshare payloads roughly 45 minutes later.

Booster B1059 separated from the rest of Falcon 9 a little over two minutes after launch and quickly flipped around to perform a boostback burn – quite literally slowing down to zero from Mach 5 and then boosting several dozen miles back towards the Florida coast. The rocket ended its fourth launch with a gentle landing at Landing Zone-1, effectively completing a ~200 km (~120 mi) aerial journey in less than eight minutes with an average velocity substantially faster than the speed of sound.

In the booster camera video SpaceX unexpectedly released after mission completion, one thing stands out above all else: an uninterrupted audio recording of the rocket from liftoff to landing. In the past, SpaceX has occasionally released the odd video from a Falcon 9 booster’s onboard camera, the most recent instance of which was published in 2016. In one other memorable case, SpaceX’s April 2018 launch of NASA’s TESS exoplanet observatory was blessed with uncut booster camera footage during the live webcast. SpaceX never technically released that footage on its own but it was easy enough to cut it from the webcast to offer a clean, uninterrupted view of a Falcon 9 booster launch and landing.

Regardless, in all prior instances and webcasts with booster camera footage, SpaceX has never included audio. It’s generally understood that most modern launch vehicles – including Falcon 9 – are outfitted with numerous high-fidelity microphones. Unintuitively, multiple separate, time-synchronized audio recordings can be used to quite literally triangulate the source of rocket hardware issues in the event of a failure – a technique SpaceX has used to its benefit to investigate Falcon 9’s first in-flight failure in 2015.

In this case, the audio serves no technical purpose but does offer the best birds-ear perspective of a Falcon 9 launch yet published. Roughly sped up by a factor of four, SpaceX’s SAOCOM 1B audio captures the passenger jet-esque whine of Falcon 9’s Merlin 1D turbopumps, the brief silence of engine cutoff, the whistle and vibration of atmospheric reentry, the thump of cold-gas thrusters maintaining the rocket’s attitude in vacuum, and even the clunk of landing leg deployment, among many other notable sounds.

Thanks to a relatively gentle and low-energy landing as a result of the low Earth orbit required by SAOCOM 1B, Falcon 9 B1059 will likely be turned around for a fifth launch and landing in the very near future. The booster may even have a shot at breaking SpaceX’s rocket turnaround record – currently held by Falcon 9 B1058 with two launches just 51 days apart.

Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.

The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.

However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.

Multi-Row Climate Control

Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility

One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.

Tesla has improved upon this with the Model Y L:

PowerShare will be included

Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.

Wireless Charging Pad

There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.

Thermal Management Improvements

These improvements in the Model Y L were seen with thermal management:

  • Up to 15% faster cabin cooling
  • +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
  • 8x more solar energy reflection off of glass roof
  • 30% reduction in solar energy entering the cabin

Demand

Tesla said the Model Y L is almost sold out in the U.S. It comes with

  • 1 year of FSD Supervised
  • 1 year of Supercharging
  • 1 year of Premium Connectivity
  • Free exterior paint color, interior, and wheel option at no additional cost

Tesla CEO Elon Musk denies ridiculous Gigafactory Shanghai rumor

Tesla CEO Elon Musk took to his social media platform X on Thursday night to deny a ridiculous rumor regarding the sale of the company’s Chinese vehicle production plant, Gigafactory Shanghai.

On Thursday, the Wall Street Journal, citing sources familiar with the matter, claimed in a scathing new report that Tesla was exploring a potential sale of the entire China business in an effort to help bolster a potential merger between SpaceX and Tesla.

Musk immediately denied the rumor not once but twice, initially calling it “fake news,” and then calling it “absurdly fake news” in a separate post just a few moments later:

The original poster of the Wall Street Journal article that Musk saw deleted the initial post sharing the headline and the rumored sale of Tesla’s China business.

The report seemed absolutely and unequivocally false to begin with; Tesla’s business in China is among the most important pieces of the company’s business. Not only does the factory supply vehicles for the domestic market, but also for various other markets in Asia and Europe.

China is also one of the largest automotive markets in the world, and Tesla has performed well there despite the robust competition.

The speculation regarding a Tesla and SpaceX merger has started to gain steam this year as the space exploration company went public just a month ago. There has been speculation that Musk will bridge all of his companies under one “umbrella company,” and analysts believe this could happen before the end of the decade.

The Tesla and SpaceX merger everyone is talking about is quietly building

This is the latest iteration of Musk’s very evident war on mainstream media. Reports regarding any of Musk’s companies are quick to get the dreaded “false” or “fake news” response from the CEO when they are unfounded.

Tesla AI boss reveals how big Optimus is going to get

Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.

Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”

The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.

The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress

Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.

Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
