SpaceX’s upgraded Starship passes first ‘cryoproof’ test after repairs
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.
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.

The Boring Company’s newest tunnel vehicle runs on Tesla parts and no one is driving it
The Boring Company’s new tunnel vehicle runs on Tesla Model 3 batteries and drive units.
The Boring Company just introduced a new piece of hardware, and it runs on parts pulled straight from a Tesla showroom. Liner Truck 3, unveiled in a post from the tunneling company’s official X account, is an all electric vehicle built around Tesla Model 3 battery packs and drive units, purpose built to move concrete tunnel segments to the boring machine face without a single person underground.
Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.

– 12 mph max operating speed

The job itself is unglamorous but critical. Each precast segment run weighs more than 22,000 pounds, roughly the load of a full cement mixer, and Liner Truck 3 hauls that weight repeatedly between the surface staging area and wherever the Prufrock machine happens to be cutting.
The Boring Company said Liner Truck 3 is piloted remotely out of its Global Operations Control Center in Texas, extending the Zero-People-In-Tunnel approach the company has spent years building toward. An earlier version of a ZPIT liner truck was already tested at the company’s Bastrop, Texas research tunnels, and a factory tour released last month showed an employee flying a fully loaded liner truck with a PlayStation controller. Liner Truck 3 looks like the production version of that same idea, cleaned up and pushed into daily use.
The timing lines up with a company digging in more places than it ever has before. The Boring Company now has multiple Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating since February, and its Vegas Loop network keeps adding tunnel mileage on a near monthly basis. Every one of those projects depends on getting concrete segments to the cutting face fast enough to keep the boring machine from idling, which is exactly the bottleneck Liner Truck 3 is designed to remove.
It also reinforces something Tesla owners have watched happen gradually across Musk’s companies: passenger car hardware finding a second life in heavy equipment. Model 3 drive units already move people through the Vegas Loop, and now the same components are hauling concrete underground in Nashville and wherever The Boring Company digs next. Whether that kind of component reuse extends further into TBC’s equipment lineup, or into other Musk owned industrial hardware, is the next thing worth watching.
SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.

The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.

The Boring Company’s newest Vegas Station has a permit quietly waiting behind it
Sahara Las Vegas opened a new Vegas Loop station, joining an exclusive two resort transit club.
Sahara Las Vegas opened a new Vegas Loop station Thursday, giving The Boring Company’s underground transit system its northernmost stop yet on the Strip. The station sits at Sahara’s Paradise Road entrance, on the southeast corner of Las Vegas Boulevard and Sahara Avenue, and connects riders to the Las Vegas Convention Center, other Strip resorts on the network and, eventually, Harry Reid International Airport.
The addition makes Sahara the second resort, after Fontainebleau opened its own station in January, to get a stop built at street level rather than tucked into the property itself. Sahara now joins Westgate as the only two Strip resorts offering both a Vegas Loop station and a stop on the Las Vegas Monorail, giving guests two separate ways to get around without leaving the property.
The Boring Company just doubled its tunneling power in Nashville
The bigger news buried in Thursday’s announcement is what comes next. Boring Company has already secured its first permit to tunnel north of Sahara Avenue, extending the network beyond where it currently ends, even though permits to push the Loop toward downtown Las Vegas still haven’t been granted. Crews are also working on a two mile dual tunnel line running from Westgate to a planned station at 4744 Paradise Road, just north of Tropicana Avenue, that Las Vegas Convention and Visitors Authority CEO Steve Hill has said the company hopes to open in time for November’s Las Vegas Grand Prix.
Ridership has grown alongside the buildout. The Loop moved roughly 82,000 passengers during CONEXPO in early March, a total the company highlighted on its own X account at the time, and the system has now carried more than 4 million passengers through 11 open stations since it began running in 2021. The airport connector tunnels, meant to give the Loop a direct link to Harry Reid, have slipped past their original first quarter target and remain under construction, with Boring Company director Mike Baier saying that a full opening is still a few months out.
For Sahara, the calculation is straightforward. Convention traffic drives a large share of Loop ridership, and a station at the property’s front door gives conventiongoers one more reason to book rooms on the Strip’s north end instead of closer to the convention center itself.
