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 Summer Update begins rolling out: a look at the new features
Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.

Tesla briefly offered this Robotaxi part for your personal car
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.

Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.

Tesla Robotaxi gets sweeping but polarizing change
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO
— Sawyer Merritt (@SawyerMerritt) July 27, 2026
However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled
— Dan Burkland (@DBurkland) July 27, 2026
Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
