SpaceX appears to have successfully completed one of three major tests standing between a new Starship prototype and the rocket’s next hop.

Known as a cryogenic proof test (“cryo proof”), signs currently point towards a success on Starship SN6’s first try – albeit an hour or two past the end of the planned test window. The proof was planned between 8 am and 5 pm CDT (UTC-5) on August 16th with identical backup windows on Monday and Tuesday in the event of an abort or delay. Thankfully, in a breath of fresh air after many Starship SN5 test delays, SpaceX had no such need.

With the help of local sheriffs, SpaceX closed the highway around 10:15 am and pressurized Starship SN6 with ambient-temperature gas (likely nitrogen) around half an hour later. As usual, the company took its time while the Starship prototype effectively came to life for the first time. Around 2.5 hours later, the Starship began visibly venting for the first time as it operated dozens of valves to maintain safe tank pressures.

LabPadre’s unofficial 24/7 livestream broadcast the entirety of SpaceX’s August 16th Starship testing.

To perform a cryogenic pressure test, SpaceX effectively performs a wet dress rehearsal (WDR) – a test that simulates a full launch flow short of liftoff – with no engine installed. To prevent leaks or hull breaches from turning potentially catastrophic during what is often the first major test of a prototype, SpaceX loads Starship with liquid nitrogen (LN2) instead of liquid methane and oxygen propellant. During that process, Starship’s thin steel skin will quickly drop to arctic temperatures, becoming cold enough that it will literally freeze the water vapor out of any ambient air it comes in contact with.

Around 1 pm local, the first sign of that frost sheath appeared but remained a sliver before disappearing around 2 pm. Starship SN6 then hung around for an hour before testing activities appeared to restart. Close to 5:40 pm, almost an hour after SpaceX’s August 16th window was meant to close, frost reappeared on Starship SN6’s hull and rapidly crept up the side of the massive rocket.

Starship SN5’s own cryo proof test – completed on June 30th – debuted apparent upgrades to SpaceX’s South Texas launch facilities, loading the rocket with hundreds of thousands of gallons of LN2 in 15-20 minutes. The ability to load huge quantities of cryogenic propellant very quickly will be critical for SpaceX, as Starship’s efficiency will decrease substantially as its propellant warms. Along those lines, Starship SN6 became the second prototype to be rapidly loaded with liquid nitrogen, going from nearly empty to nearly full in ~15 minutes.

SN6 detanked over the next hour or so and SpaceX opened the road and had a team back on the pad to inspect the rocket by 7:40 pm. At some point during the test, SpaceX likely actuated hydraulic arms attached to Starship’s engine section to simulate the stresses of Raptor thrust under cryogenic loads. Either way, SpaceX was apparently satisfied with the results of Starship SN6’s first cryo proof and proceeded to cancel two backup windows scheduled on August 17th and 18th – a consistent sign that things either went very right or very wrong.

In the case of SN6, nothing was distinctly amiss or different during its cryo proof, pointing towards a successful test. If that’s the case, SpaceX will begin removing the hydraulic Raptor simulator to install an actual Raptor engine and will scheduled road closures for an imminent static fire test. Prior to that actual Raptor ignition test, SpaceX may choose to perform a wet dress rehearsal (WDR) on its own or partially test Raptor by igniting its preburners to momentarily spin up its turbopumps. The company could also integrate both of those precursor tests into the same window as the static fire itself.

If those tests go according to plan, Starship SN6 could be ready for SpaceX’s second full-scale hop ever just a week (or less) later. CEO Elon Musk says that the company’s current goal is to perform multiple Starship tests until the process is fast, smooth, and consistent.

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.
