SpaceX Starship booster weathers thunderstorm ahead of first ‘cryo proof’
Update: SpaceX’s first Super Heavy cryo proof test is now scheduled no earlier than 6pm to 12am CDT (UTC-5) on Thursday, July 8th 6am to 8pm CDT (UTC-5) on Friday, July 9th. Weather is suboptimal, with intermittent heavy rain – to the extent that a flash flood warning is in effect until Friday evening – expected over the next few days.
Nevertheless, Booster 3 was spotted venting for the first time ever around 9am, suggesting that SpaceX might still try for at least a test or two later today or tomorrow.
Meshing with road and beach closures requested earlier this week, Next Spaceflight reports that a SpaceX Super Heavy booster is scheduled to attempt a ‘cryo proof’ test for the first time as early as Thursday, July 8th.
Known as Booster 3 (B3), SpaceX rolled the first functional Super Heavy prototype – the largest rocket booster ever completed – from the factory to the launch pad on July 1st. One week later, SpaceX appears to be on track to kick off Super Heavy’s first fully-integrated qualification testing, building off of an apparently successful campaign of pressure testing with booster test tank BN2.1. After completing several tests, BN2.1 was rolled back to a scrapyard near SpaceX’s Boca Chica factory, while part of the custom-built stand used for the campaign was then reinstalled on one of the two ‘suborbital mounts’ used for Starship testing over the last year.
Mere days after Mount A’s modifications were completed, Super Heavy Booster 3 was transported to the pad and installed atop it. For whatever reason, SpaceX technicians and engineers spent the next week scouring the rocket’s exterior and interior with the help of an army of boom lifts, turning the basic structure into a functional pressure vessel with all necessary power, telemetry, and plumbing.
99% of that closeout work could have seemingly been done under the cover of SpaceX’s high bay, where Booster 3 was assembled out of dozens of steel rings and domes, but the work appears to have been completed regardless. Workers had to contend with routine South Texas downpours and thunderstorms on Tuesday and Wednesday but were otherwise subjected to fairly mundane winds and weather.
Conditions were most dramatic on Tuesday, with torrential rain only interrupted by the occasional lightning bolt – though Booster 3 and the orbital launch pad’s skyscraper-sized launch tower appeared to make it through the day strike-free.
Now seemingly fully outfitted with all necessary avionics, wiring, and plumbing, Booster 3’s next major objectives will be ambient and cryogenic proof tests, referring to the process of verifying the structural integrity of the rocket first with benign nitrogen gas and later with supercool liquid nitrogen. SpaceX has performed at least a dozen or two ‘cryo proofs’ over the last 18 months and, at this point, qualification testing is fairly routine.
However, Super Heavy B3 is the largest rocket booster ever built and testing such a massive rocket will necessarily force SpaceX to tread some new ground. In fact, it’s not actually clear how exactly SpaceX will perform Booster 3’s first cryo proof given that the suborbital launch complex hosting it has nowhere near enough cryogenic storage capacity to fully fill Super Heavy with more than 3000 tons (~6.6 million lb) of liquid nitrogen.
As always, testing massive, brand-new rockets is no simple feat, so delays are possible – if not outright likely. Regardless, Super Heavy B3’s first test window is scheduled from noon to 8pm CDT (UTC-5) on Thursday, July 8th, with two backups from 6am to 8pm on July 9th and 12pm to 8pm on July 12th. Stay tuned for updates on the first tests of a full-size Super Heavy booster!

NHTSA just escalated its Tesla Cybercab investigation in a big way
NHTSA escalated its Cybercab audit into a sworn Special Order with a September 30 deadline.
Federal regulators have moved from asking Tesla questions about its Cybercab to demanding sworn answers. The National Highway Traffic Safety Administration issued a Special Order that requires a Tesla officer to sign an affidavit attesting to the completeness of the company’s responses, with a deadline of September 30.
The order builds on Audit Query AQ26002, which NHTSA opened on September 3, the same day Tesla began commercial Cybercab service in Austin. Teslarati covered that initial inquiry when it surfaced, noting the agency wanted to understand how Tesla certified a vehicle with no permanently attached steering wheel, pedals, or mirrors as compliant with Federal Motor Vehicle Safety Standards. A Special Order is a different tool and converts a fact finding review into a legally enforceable demand, the same mechanism NHTSA used against Tesla in 2023 during its Autopilot investigation.
Several of the 21 requests target a specific gap in Cybercab’s design. One asks whether Tesla used temporarily attached human controls at any point to help certify the vehicle, and if so, which standards depended on that equipment being present. Another quotes an existing rule directly: “The service brakes shall be activated by means of a foot control.” Cybercab has no foot pedal. NHTSA wants a detailed explanation of how the vehicle satisfies that requirement, and how it complies without the kind of exemption granted to Zoox in July under Part 555, the regulatory pathway built for steering wheel free vehicles.
The order does not claim Cybercab is unsafe or that Tesla broke a rule. It requires Tesla to explain, under oath, the reasoning behind decisions the company already made when it self-certified the vehicle. That distinction matters, but so does the exposure. Motor1’s reporting, summarized here, put potential civil penalty exposure as high as $139 million if NHTSA later finds the certification was flawed, on top of whatever criminal risk comes with a false sworn statement.
Tesla has not said publicly how it plans to respond. Cybercab is still carrying passengers in Austin through the Robotaxi app while the September 30 deadline approaches, and the company has continued expanding the vehicle’s footprint even as the regulatory question remains open. The Special Order does not pause any of that and just sets a date by which Tesla has to put its certification logic on the record, with a company officer’s name attached to it.
In a new interview on Wednesday, Tesla uber bull Ron Baron said that anyone looking to buy the company’s stock should do so as soon as they can.
Baron, founder and CEO of Baron Capital and one of Tesla’s most persistent institutional bulls, used a CNBC Squawk Box appearance on Wednesday to deliver a familiar message with fresh urgency: In his opinion, Tesla stock is a buy:
“The time to buy the stock is now. FSD is catching on, and it’s going to be bigger and bigger. 55% of new buyers are buying it (Teslas) with FSD. It’s going to be everywhere. It’s safer.”
The Baron Capital frontman’s case is built around Full Self-Driving. Tesla reported 1.48 million active FSD subscriptions in the second quarter, up 56 percent year over year, and company officials have said roughly 55 percent of new North American deliveries left with a subscription enabled.
Baron framed that attach rate as proof the product is moving from enthusiast extra to default expectation, and as a reason software, not just vehicle volume, should drive the next phase of value.
His conviction on Tesla shares is not theoretical, as Baron Capital made its first Tesla investment in 2014, after years of meetings that began around the 2010 IPO roadshow. The firm later built a large SpaceX position starting in 2017.

Baron said those Musk-led bets have generated about $30 billion of the $71 billion in profits Baron Capital has produced for clients. He put the firm’s current exposure at roughly $25 billion in SpaceX and $5 billion in Tesla. Personally, he described SpaceX as his largest holding, at about $5 billion, with about $1.5 billion in Tesla and additional Tesla exposure through the firm’s funds.
That concentration is also a statement of loyalty. Asked about talk of a SpaceX-Tesla combination, Baron said he had already walked Elon Musk through arguments for and against a deal, then declined to repeat them on air. His public position was simpler: “Whatever you decide is better is what I’m going to support,” he said to Musk.
Baron also said that he picked up the farewell edition of the Model S after Tesla decided to sunset the vehicle earlier this year, calling it his favorite car he’s ever driven.

SpaceX’s next Starship launch is about to attempt its biggest leap yet
SpaceX targets September 22 for Starship Flight 14, its first attempt to reach real orbit.
SpaceX has set September 22 as the target date for Starship’s 14th test flight, and this one carries a different goal than any of the 13 that came before it. Every previous Starship mission has intentionally flown a suborbital arc, reentering the atmosphere within the same hour it launched. Flight 14 is designed to send the craft into a genuine orbit around Earth for the first time.
The launch window opens at 7:15 a.m. Central time at Starbase in South Texas and runs for 75 minutes, pending regulatory approval, according to SpaceX’s mission description published Tuesday. If the flight goes as planned, Starship will circle the planet roughly six times at an altitude near 275 kilometers over about ten hours before a deorbit burn sends it toward a splashdown in the Pacific Ocean west of Chile, a departure from the Indian Ocean recoveries used on the last several flights.
The mission also marks the first attempt to put a working batch of Starlink V3 satellites into actual service. Flight 13 carried 20 of the new satellites in July, but because that mission never left a suborbital trajectory, the payload reentered along with the ship instead of separating into orbit.
SpaceX tells the FCC that Starship Flight 14 is going to orbit
Each V3 satellite is rated for roughly one terabit per second of downlink capacity, so a successful deployment on Flight 14 would be SpaceX’s largest single jump in network bandwidth since Starlink began flying on Falcon 9.
Flight 13 still did the heavier lifting on the technical side. That July mission flew a deliberately more stressful reentry profile to test Starship’s heat shield, and the ship survived its softest splashdown yet, intact enough for drone inspections shortly after landing. Elon Musk said the flight delivered “all the heat shield data we needed and then some,” a result Teslarati covered in detail when he later said SpaceX had solved the vehicle’s biggest reusability challenge. Flight 14 is where SpaceX starts spending that confidence on an actual orbital insertion rather than another controlled fall back to Earth.
One thing Flight 14 will not attempt is a tower catch of the ship. Musk floated the idea right after Flight 13, but walked the timeline back in August, saying a catch attempt was more likely “in a few months.” The Super Heavy booster will still aim for its own recovery, targeting an offshore landing point in the Gulf of America, the same approach used on recent flights.
September 22 is SpaceX’s own target, not a locked date. Starship’s schedule has slipped before over hardware readiness and FAA sign off, and the company has said as much in its own mission notes. But the plan itself represents the clearest marker yet that Starship is moving from a suborbital test program into something meant to carry paying payloads and, eventually, people.
