SpaceX CEO Elon Musk says an upgraded Starship prototype has passed its first cryogenic proof or ‘cryoproof’ test after undergoing a week of repairs.

Around noon, local sheriffs closed the road to Starbase’s orbital launch site (OLS) and SpaceX cleared the pad of all personnel, freeing up Starship S24 for the next stage of testing. A week prior, on May 27th, Ship 24 suffered some degree of internal damage during a simpler pneumatic proof test with ambient-temperature nitrogen gas. It’s now clear that most of that pneumatic proof test was successful, demonstrating that the Starship’s main propellant tanks and associated plumbing and valves were structurally sound and working as expected.

Still, for about a week after that first test, teams of SpaceX workers swarmed the Starship prototype 24/7 and were seen extracting damaged plumbing and carefully transporting replacement parts inside. Only on the morning of June 2nd was Ship 24 sealed up again.

Cryogenic fluid loading – liquid nitrogen or a combo of LN2 and liquid oxygen (LOx) – began shortly before 3pm CDT (UTC-5) and the Starship’s main tanks were fully filled about 70 minutes later. SpaceX then let those fluids naturally warm, causing a small portion to boil into gas and gradually raise the pressure inside Ship 24’s main tanks. As the pressure grew, sections of the layers of frost and ice that formed on the outside of its thin steel tanks occasionally sloughed off in sheets or broke off in fragments – the only evidence of stress aside from venting.

After about an hour fully filled, SpaceX began detanking and depressurizing Ship 24. The road and pad were reopened around 8:40 pm. All told, aside from an apparent leak on its liquid oxygen tank access hatch, a very common occurrence, Ship 24 exhibited no unusual behavior and made it through its first cryoproof without any obvious issue. More importantly, SpaceX did not appear to reattempt the pneumatic proof test the ship partially failed before the harder cryoproof test, implying that its first test was mostly successful. CEO Elon Musk later confirmed that the Starship had passed its first cryoproof test a few hours after.

A large piece of plumbing with right-angled diversions known as ‘expansion loops’ was carefully threaded through Ship 24’s upper access port and installed as recently as June 1st.

Despite Musk’s positive comment, there was no evidence of activity in Ship 24’s nose section, where a number of crucial vents and secondary header tanks – meant to serve as attitude control thrusters and store landing propellant – are located. Ship 24 is the first Starship prototype with a new design that moved both header tanks into the tip of the nosecone. The nose itself is also the first with a number of other manufacturing and design upgrades to reach a test stand, so verifying that it works as expected is doubly important.

Given that the plumbing that failed in the first test may have been connected to Ship 24’s nose section and header tanks and that neither was obviously involved in the subsequent June 2nd cryoproof, it’s likely that the Starship prototype is not done with cryoproof testing just yet. Nonetheless, the ship’s survival and passage of its first cryoproof bodes well for the next steps.

In the near future, SpaceX is expected to move Ship 24 to a nearby ‘suborbital pad’ and test stand that has been significantly modified to simulate the thrust and mechanical stress of six Raptor 2 engines. If or when Ship 24 passes that test or tests, SpaceX will likely remove the stand’s hydraulic rams and begin installing Raptor engines and associated heat shielding. Then, Starship S24 can enter the final stages of qualification: wet dress rehearsal and static fire testing.

SpaceX has requested additional road closures for potential testing on June 6th, 7th, and 8th.

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be.

tesla austin robotaxi geofence and elon musk laugh from meme review

Tesla expanded its Robotaxi geofence in Austin once again early Sunday morning. The new shape seems to be somewhat of a proverbial, and potentially literal, middle finger to the competition.

If you thought the first expansion was a message to the competition and doubters of the company’s ride-hailing service, you probably will believe the second expansion is an even stronger gesture.

Tesla’s first expansion did not go unnoticed, as its shape was particularly recognizable. The company has always operated with a sense of humor, and it embraced what it did. Some, including me, took it as a message to competitors: We can expand in any direction, in any size, at any time. We’ll prove it.”

They picked a shape and went with it:

Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors

It is evident that Tesla is keeping its humor up to continue to show a few things. The first is that it really can expand in any direction it wants and that’s how it is choosing to show it.

The second, well, maybe it’s an edgier way to show doubters that it is really executing on Robotaxi:

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be. This might be a similar occurrence, and it might be sending another message to the competition, critics, and doubters.

The expansion was a near-doubling of the geofence Tesla offered previously. After the initial geofence covered just about 20 square miles, Tesla was able to more than double it to 42 square miles with the first growth. This new geofence shape was just under double, and is about 80 square miles.

Tesla’s rapid expansion has impressed many, especially considering the service area has roughly doubled for the second time in well under two months. The Robotaxi service was first offered on June 22.

Tesla executes ‘a must’ with Musk as race to AI supremacy goes on: Wedbush

Dan Ives of Wedbush says Tesla made the right move getting Elon Musk his pay package.

Tesla (NASDAQ: TSLA) executed what Wedbush’s Dan Ives called “a must” this morning as it finalized a new pay package for its CEO Elon Musk.

The move helped give Musk his first meaningful compensation at Tesla since 2017, when the company offered a pay package that was based on performance and proven growth. That package was approved by shareholders on two separate occasions, but was denied to Musk both times by the Delaware Chancery Court.

On Monday, Tesla announced on X that it had created a new package that would give 96 million shares of restricted stock to Musk to compensate him for the “immense value generated for Tesla and all our shareholders.”

The details of the pay package are designed to retain Musk, who has voiced some concerns about his control of Tesla, as “activist shareholders” have used lawsuits to disrupt the previously approved package.

Tesla rewards CEO Elon Musk with massive, restricted stock package

Ives says Musk’s retention is ‘a must’

Ives said in a note to investors on Monday that with the raging AI talent war that Tesla made a smart move by doing what it could to retain Musk.

He wrote:

“With the AI talent war now fully underway across Big Tech, we believe this was a strategic move to keep TSLA’s top asset, Musk, would stay focused at the company with his priority being to bolster the company’s growth strategy over the coming years. With this interim award increasing Musk’s voting rights upon this grant, which Musk honed in on and mentioned was increasingly important to incentivize him to stay focused on the matters at hand, this was a strategic move by the Board to solidify Musk as CEO of Tesla over the coming years with this framework for Musk’s pay package and greater voting control removing a major overhang on the story.”

He went on to say:

“While the groundwork is now in place for the next few years, it will be critical for the Tesla Board of Directors to get this long-term compensation strategy in place prior to the company’s November 6th shareholder meeting which would address the elephant in the room and remove a significant overhang on the stock.”

Wedbush maintained its Outperform rating and its $500 price target on the stock.

Tesla CEO Elon Musk reveals ideal timeline for insane self-driving feature

Tesla CEO Elon Musk has extremely optimistic expectations for Full Self-Driving progress by the end of 2025.

Tesla CEO Elon Musk has revealed his ideal timeline for what would likely be the most insane self-driving feature: the ability for drivers to play video games at the wheel.

There are a handful of videos out there of drivers already performing this task. Nobody using Tesla’s Full Self-Driving suite should perform these activities, as the company maintains the system is not fully autonomous.

Drivers are responsible for the vehicle and should be prepared to take over.

Tesla has put a lot of faith in its development of Full Self-Driving and has made tremendous strides over the past few years. Capabilities have gotten more refined and accurate through various methods, including data collection and hardware improvements.

Tesla kicks Robotaxi geofence expansion into high gear in Austin

It has gotten so good that Tesla launched a Robotaxi platform in Austin, Texas, on June 22. Passengers can hop in the back of a Model Y and will be transported around the city in a confined geofence that is about 90 square miles in size. There is nobody in the driver’s seat, but there is a Safety Monitor in the passenger’s seat.

Tesla launched a similar experience in California’s Bay Area last week, but the company has placed the Safety Monitor in the driver’s seat for that region for the time being.

Eventually, Tesla will get to a point where no monitor is needed, and the vehicles will be able to drive themselves. Many believe that it is a few years away, but Musk believes Tesla could achieve it very soon.

After a video of someone playing Grand Theft Auto in their Cybertruck while operating Full Self-Driving was shared on the social media platform X, Musk said this capability would be available in “probably 3 to 6 months, depending on regulatory approval in your city and state.”

It is important to remember that Musk has been very optimistic regarding autonomy timelines with Tesla projects. We heard for many years that the company would have self-driving vehicles “by the end of the year,” and those projects did not come to fruition.

While there was progress, there were no fully autonomous vehicles or software versions for customers.

With that being said, Tesla has made tremendous strides in its quest for autonomous vehicles this year, and launching a Robotaxi platform was a huge step in the right direction.
