SpaceX’s repaired Starship booster survives back-to-back cryoproof tests
SpaceX’s upgraded Starship booster has completed a second and third cryogenic proof test in rapid succession after undergoing repairs to fix damage suffered during the first round of testing.
Testing began almost immediately after SpaceX rolled the repaired Super Heavy booster back to the orbital launch site (OLS) on May 6th. After a quick installation on the pad’s stool-like launch mount and another day of systems checks and integration, Booster 7 charged headfirst into its first post-repair cryoproof on May 9th.
Instead of cautiously feeling out the repaired plumbing and header tank over a series of small tests, SpaceX immediately performed a full cryogenic proof (cryoproof) and filled Booster 7 to the brim with about 3000 tons (~6.6M lb) of liquid nitrogen (LN2) or a combination of LN2 and liquid oxygen (LOx). Standing about 67 meters (~220 ft) tall and 9 meters (~30 ft) wide, it took about two hours to fully fill Super Heavy’s tanks with the equivalent of one and a half Olympic swimming pools of cryogenic liquid.
As always, that liquid (well below –320°F or –196°C) rapidly chilled the booster’s 4mm (~0.16″) thick steel tanks to cryogenic temperatures, which then froze moisture directly out of the humid Texas air, coating almost all of Super Heavy’s exterior with a layer of frost and ice.
SpaceX began detanking Booster 7 soon after the fill process was completed. Thanks to plenty of insulated plumbing and well-insulated ground storage tanks, SpaceX is able to recover nearly all of the LN2 and LOx used during cryoproof testing, which helps avoid the hundreds of semi-truck delivers that would otherwise be required to replenish the tank farm after even a single test.
As if to demonstrate that, SpaceX proceeded to put Booster 7 through a whole new cryogenic proof test just two days later, on May 11th. Once again, Super Heavy was fully loaded with thousands of tons of liquid nitrogen and oxygen. Unlike Cryoproof #2’s immediate detank, SpaceX – judging by the frost levels – kept Booster 7 topped off for a good hour before detanking.
In a last-minute surprise, after fully detanking B7 at the end of Cryoproof #3, SpaceX refilled the booster’s liquid oxygen tank with a few hundred tons of LN2 or LOx. Once the rocket’s thrust section reached some degree of thermodynamic equilibrium, SpaceX remotely retracted and reconnected the orbital launch mount’s Super Heavy umbilical. The launch mount umbilical or ‘quick disconnect’ is responsible for connecting Super Heavy to the pad’s gas supplies, propellant storage, power, and communications. The test SpaceX completed after Cryoproof #3 may have been a rough simulation of one scenario Starship could easily face: a post-ignition launch abort. In other words, if an orbital Starship launch was aborted just before liftoff but after quick-disconnect retraction, could it quickly reconnect to the booster with zero human intervention?
In a scenario where a QD failed to reattach to a fully-fueled Super Heavy after a launch abort, the odds of a catastrophic fire or explosion would immediately shoot up to near-certainty. In moderate quantities, simultaneously venting gaseous methane and oxygen from the same rocket is risky but manageable. Venting hundreds – let alone thousands – of tons while trapped on the ground would amount to creating a multi-hour fuel-air bomb just waiting for a spark. Multiple Starship prototypes (SN4, SN10) have already been destroyed in part by the flammability of methane gas.
Combined with the completion of two full cryogenic proof tests in less than two days, it appears that Super Heavy B7’s repairs were extremely successful. Had the first post-repair cryoproof not gone more or less perfectly, it’s hard to imagine that SpaceX would have attempted or completed an almost identical test two days later. If the second cryoproof hadn’t been nearly perfect, it’s even harder to imagine that SpaceX would have accepted the risk involved in detaching Booster 7’s umbilical during the same test window.
On May 12th, SpaceX’s main pad crane attached a lift jig to Super Heavy B7, implying that it will likely be removed from the orbital launch mount in the near future. If the repaired booster aced its tests, SpaceX’s next step would likely be Raptor engine installation and the start of static fire testing. It’s unclear if SpaceX wants to install all 33 engines at once or begin with a small handful. It’s also unclear if SpaceX will return Booster 7 to Starbase’s production facilities to finish Raptor, heat shield, grid fin, and aerocover installation.
Tesla owners have long griped about the wireless phone charger in the Model Y and other vehicles. It often turns smartphones into miniature ovens rather than reliably topping them up.
Software engineer and Model Y owner Michał Gapiński tackled this issue head-on with a clever DIY upgrade, swapping the cooled wireless charger pad from the China-made Model YL in for the one that came standard in his vehicle.
There are several key differences between the U.S.-built Model Y’s wireless charging pad and the one that Tesla has been installing in the Model YL. The one installed in U.S.-built vehicles lacks active cooling and relies on basic heat dissipation, leading to rapid temperature buildup during charging. In contrast, the Model YL integrates a small fan for active cooling.

This design maintains lower temperatures even in warm ambient conditions, though it does not support faster Qi2 charging on iPhones. The connector matches exactly, making physical swaps feasible on compatible consoles, but coding is required to enable full functionality.
Owners in the U.S. have complained about the wireless charging pad, with many reporting that overheating is fairly common. Within 20 or 30 minutes of placing a phone on the wireless charging pad, many have reported overheating messages on their phones, which halt charging and essentially turn the pad into a fancy place to rest your phone.
Many owners have opted to simply plug their phones into a charging cord. Tesla has acknowledged the problem by releasing several solutions for owners, including a relatively new feature that allows you to simply turn off the charging and simply act as a holder for your phone while driving.
Gapiński said that he sourced the cooled pad affordably from China, and it cost under $200 for the part.
He removed the existing console charger, swapped in the new unit, confirming a perfect connector fit, and handled the trim differences. Since the parameter isn’t fully secured, he enabled it through custom coding outside official Toolbox.
Connector is identical, she fits, now time to code it. https://t.co/Y9idgDrpCq pic.twitter.com/uwwgq6blg7

The fan activates quietly, blending with AC and seat cooling. He reported the installation was effective and the wireless charging pad worked perfectly; it even kept the phone cool as it stayed at just 86 degrees Fahrenheit. Many times, the wireless charging pad will bring the phone’s temperature well above 100 degrees, sometimes even being relatively hot to the touch.
The retrofit worked, no issues. First Model Y with a cooled wireless charger! No QI2/faster charging on the iPhone but it does not boil the phone even when it is 30 degrees outside.
The fan kicks in, it is not audible especially with the air conditioning and seat cooling. The… https://t.co/JOyR8Tb1Yo pic.twitter.com/kJcYhQIlYq

This retrofit highlighted an elegant, owner-driven solution to a factory shortcoming. It is expected that Tesla will begin installing the cooled charging pads into new cars in the U.S. soon, and hopefully, it will offer some sort of retrofit service or kit to owners here who want to use the charging pad effectively.
For those who love to tinker, it’s an accessible upgrade, proving that innovation thrives beyond the production line.
The Tesla Roadster unveiling could be coming “in a few weeks,” according to the company’s Chief Designer Franz von Holzhausen, who said at the Tesla Takeover Europe Event in Austria that the all-electric hypercar could finally make its way to the production line after years of anticipation.
Von Holzhausen delivered the news just days after The Information reported that Tesla planned to push the Roadster unveiling to August. It was slated for both April and May of this year, but now it seems the company is leaning toward a late Summer event to cap off the heat with perhaps its most anticipated vehicle of all-time.

Franz has been with Tesla since 2008, and has played a pivotal role in the iconic design language the company has utilized with its vehicles. Speaking to the crowd in Austria virtually, von Holzhausen’s comments injected fresh excitement into a project that has been plagued by delays for nine years.
The second-generation Roadster promises to redefine supercar standards. Tesla’s website still highlights ambitious targets: 0-60 mph in under 1.9 seconds (with optional SpaceX thruster pack potentially achieving 1.1 seconds or less), a top speed exceeding 250 mph, and a range of about 620 miles.
Equipped with a tri-motor all-wheel-drive setup delivering over 1,000 horsepower, the four-seater aims to blend blistering acceleration, everyday usability, and innovative features like cold gas thrusters for short-hop capabilities, technology that will combine the project with SpaceX.
But years after the company promised to start production, which was slated for 2020, the timeline for the Roadster has continued to shift.
Tesla has strung along those who have put $50,000 deposits down, as well as fans and enthusiasts of the company who have been long awaiting the company to bring forth a car truly designed for the human driver, and not autonomy. The Roadster is more than just a halo vehicle for Tesla; it showcases the company’s ability to push the boundaries while incorporating synergies from other Musk companies.
However, it has to make it to production, which is something Musk and Co. have pushed back repeatedly.
As Tesla navigates Robotaxi development and broader autonomy goals, the Roadster serves as a reminder of its performance roots. If von Holzhausen’s timeline holds, fans could witness this engineering marvel by late June or early July 2026. Whether a full unveiling, demo, or initial deliveries, it marks a milestone for electric supercars.
Tesla has reportedly pushed the unveiling of the Roadster once again, but there are also evidently new details about the event that the company plans to show off.
The Information reported this morning that Tesla will now unveil, for the second time, the next-generation Roadster in August, a further delay from the multiple timeline that the company had previously stated.
The report has not been confirmed or denied by Tesla at any capacity.
It also states the unveiling event will take place in Texas, the same place that Tesla executives revealed in May would be the place of manufacture for the company’s highly-anticipated supercar, which boasts a top speed of over 250 MPH and 650 miles of range, according to its website.
Tesla is also expected to showcase the SpaceX package, which will be used for faster acceleration and potentially hovering capabilities, at the unveiling event, the report states. Musk has always planned for this to happen, but now it seems it is more realistic than ever

The Roadster has had its unveiling date and manufacturing date pushed back on many occasions. It was set to start production in 2020, but the COVID-19 pandemic crippled supply chain operations, forcing Tesla to push its timeline back considerably.
However, COVID has been over for some time, and Tesla has still not managed to successfully schedule and execute an unveiling event, which is something fans and enthusiasts, as well as those who have put down a $50,000 deposit, have been waiting for.
The vehicle was close to completion last year, but Musk truly wanted Lars Moravy and Franz von Holzhausen to push the limits of the Roadster. In July of last year, Moravy said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
It is important to note two things: Tesla has not confirmed these details, and the company has regularly pushed these dates back. Until Tesla sends out formal invitations with a concrete date, taking any unveiling event reports with a grain of salt is a good idea.
