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 updates Cybertruck owners on timeline of massive feature yet to ship

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.

Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.

Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.

However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.

Powerwall discharge would be prioritized before tapping into the truck’s larger pack.

However, Tesla is still working on getting the feature out to owners, an email said:

“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026. 

This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”

Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.

Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.

Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”

It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.

Tesla’s northernmost Supercharger in North America opens

Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.

Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.

There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.

Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.

Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.

Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.

Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.

Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla shocks with latest Robotaxi testing move

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.

Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.

However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.

Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.

Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”

However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.

Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.
