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.

Elon Musk just upped his Tesla stake further fueling SpaceX merger conversation
Elon Musk just collected a $116 billion Tesla payday and the timing is eye-opening
Elon Musk quietly collected one of the largest single-transaction paydays in corporate history on Monday. A Form 4 filed with the SEC on June 17, 2026 disclosed that Musk exercised 303,960,630 Tesla stock options from his 2018 compensation package, with the transaction dated June 16. No shares were sold on the open market.
The numbers are straightforward but striking. Musk exercised the options at a split-adjusted strike price of $23.34, with Tesla closing at $404.66 that day, putting the spread at $381.32 per share and generating roughly $115.9 billion in paper gains in a single transaction. To cover the exercise cost, Tesla withheld 17,531,857 shares through a net share settlement, meaning Musk paid nothing out of pocket.
For perspective, in 2018, Elon Musk’s award was originally approved by Tesla shareholders on March 21, 2018, and structured entirely around performance milestones that many analysts at the time called unreachable. Every tranche eventually vested. The original grant covered 20,264,042 shares at $350.02, which after Tesla’s 5-for-1 split in 2020 and 3-for-1 split in 2022 adjusted to 303,960,630 shares at $23.34. A Delaware court rescinded the award in January 2024, ruling the board was conflicted. As Teslarati reported, Tesla shareholders voted to ratify the package anyway in June 2024 by a wide margin. The Delaware Supreme Court reversed the decision in December 2025, finding full cancellation too extreme, and Tesla’s board signed an Implementation Agreement on April 21, 2026 to formally deliver the shares.
The Tesla and SpaceX merger everyone is talking about is quietly building
The timing and structure of the Form 4 filing carries more weight than a routine stock option exercise typically would. Musk exercised his 2018 Tesla award on June 16, a week into SpaceX completing its IPO and trading publicly, and giving SpaceX a public market valuation and share currency for the first time in the company’s history. A stock-for-stock merger between two companies requires the acquiring entity to have tradeable shares it can offer to the target’s shareholders, and SpaceX now has exactly that. At the same time, Musk just increased his direct Tesla voting power to approximately 20%, giving him greater influence over any shareholder vote that a merger would require. The restricted shares he received cannot be sold until 2033, which removes any near-term incentive to cash out and instead positions this stake as long-term structural collateral in a deal. Additionally, Musk’s two companies are already deeply intertwined through shared semiconductor fabrication at their joint TERAFAB facility in Austin, cross-company supply chain transactions, and Tesla’s $2 billion investment in xAI prior to the SpaceX-xAI merger.
Wedbush analyst Dan Ives has publicly placed the odds of a Tesla and SpaceX combination at 80% to 90% by early 2027. The Implementation Agreement that made Monday’s exercise possible was signed on April 21, 2026, roughly two months before the SpaceX IPO closed. That sequencing, building Musk’s Tesla ownership to its highest point ever immediately before SpaceX gains the public currency needed to acquire it, is either an extraordinary coincidence or a carefully staged foundation for the largest corporate merger in history.
Tesla Full Self-Driving is going to be getting a major parking upgrade. That’s according to CEO Elon Musk, who detailed a crafty new feature that will improve parking preferences, removing a layer of human input.
Musk said that upcoming releases of Full Self-Driving will “remember your parking preferences.” It will go to the location you prefer, based on where you’ve parked in the past, instead of taking the first spot available, which is where the suite is currently.
The CEO went on to explain that destination parking is “by far” the biggest reason for intervention during FSD operation. We’d have to believe this is true; many takeovers in my Model Y, which runs the latest version of FSD as it is in the Early Access Program, are due to parking because it chooses a spot I do not want to be in.
Many times, as soon as I enter a parking lot, I take over and park manually. I prefer to park away from the entrance of wherever I am, away from cars. Too many lessons learned over the years from people with free-swinging doors.
Upcoming releases of FSD will remember your parking preferences, so that the car goes to the right location at your home, office, school drop off, etc.
Destination parking is by far the biggest reason people now intervene with FSD. Critical safety interventions are extremely…

We’d imagine these new updates will also solve things like parking orientation. Let’s say when you arrive at work, you always park in the third spot in the third row, and you prefer to back in. It seems as if Musk is implying that your car will now do this, learning from takeovers and aiming to eliminate the need to manually park whenever possible.
This is a major upgrade because parking is a major shortcoming of FSD currently. We’ve requested things like manual input of parking preferences, choosing to park far away, first available, or away from cars, for example.
This is a big reason Parking Preferences with Supervised FSD will be so valuable.
If possible, parking a little further away and being distant from people like this is worth it. https://t.co/1YqQLgnfTz pic.twitter.com/3Ac71KQiQ3

However, some have used the option of dropping a pin at the location you’d like to park at your destination. This has worked some of the time, but FSD will still choose to park in whatever it sees first.
Musk did not give a timetable for when the improvements would be released, but it is likely to come soon. Tesla has been releasing a new FSD version every few weeks, so we may not have to wait long to test it.
In a remarkable demonstration of how advanced vehicle technology can intersect with family care and rapid response, a Tesla Model Y equipped with Full Self-Driving (FSD) Supervised helped save a driver’s life during a severe heart attack. The incident, which occurred on November 15, 2025, highlights the life-saving potential of Tesla’s connected ecosystem.
John Brandt, 55, was driving his new 2026 Model Y Launch Edition on Interstate 20 from Atlanta toward Birmingham early that morning. He had recently received the FSD v14.1.3 update. Around 3:50 a.m., he began experiencing severe chest pain. Barely conscious and unable to safely control the vehicle, John managed to call his son, Jack Brandt.
FSD Supervised remained engaged, keeping the car steadily on course while John reached out for help.
As an authorized driver on his father’s Tesla account, Jack quickly sprang into action from his own phone. He located Tanner Medical Center in Carrollton, Georgia—a facility equipped for cardiac emergencies—via Google Maps and shared the destination directly through the Tesla app.

The Model Y responded immediately, rerouting: it took the next exit, turned around on I-20, navigated local roads, and pulled directly up to the emergency room entrance. Jack also alerted hospital staff that a heart attack patient was en route in a Tesla.
Doctors diagnosed John with a massive STEMI heart attack, requiring immediate intervention on three blocked arteries. They later confirmed that without the swift reroute, John likely would not have survived—whether he had pulled over to wait for an ambulance or attempted to continue driving. He received life-saving treatment and is now recovering fully.
Tesla shared the story on X, including an interview video featuring John and Jack reflecting on the event. John described the terrifying onset of symptoms, while Jack detailed the ease of remote intervention thanks to the app’s features. Only authorized users with vehicle access can change navigation destinations, adding a layer of security and family coordination.
This case underscores Tesla’s emphasis on connectivity and supervised autonomy. Features like remote navigation allow loved ones to assist in real-time emergencies, while FSD handles complex driving tasks reliably. Tesla notes that FSD Supervised requires active driver supervision and is not fully autonomous; this was a specific incident, not a general emergency protocol.
The story has resonated widely, with many praising Tesla’s technology for bridging gaps in critical moments. Jack previously shared details on social media in February 2026, and Tesla’s recent post has amplified its reach. As vehicles become smarter and more connected, such integrations could redefine personal safety on the road—turning cars into proactive partners in health crises.
For Tesla owners, the incident serves as a powerful reminder to add trusted family members as authorized drivers and explore FSD capabilities. While no technology replaces professional medical care, this blend of AI-assisted driving and seamless app control proved invaluable. John’s survival stands as a testament to innovation that prioritizes human life.
