SpaceX Starship boosters could forgo landings entirely, says Elon Musk

SpaceX CEO Elon Musk says that Starship’s Super Heavy boosters could forgo landings entirely, relying instead on a wild crane-based solution to recover the world’s largest rocket stage.

As previously discussed on Teslarati, the Super Heavy booster tasked with carrying a ~1400-ton (~300,000 lb) Starship around 25% of the way to orbit will be the largest rocket stage ever built – and by a large margin.

“Standing about as tall as an entire two-stage Falcon 9 rocket at 70 meters (230 ft) tip to tail, the Super Heavy booster tasked with getting Starship about a quarter of the way to orbit will be the largest rocket stage ever built. Outfitted with up to 28 Raptors capable of producing more than ~7300 metric tons (~16.2 million lbf) of thrust at liftoff, Super Heavy will also be the most powerful rocket ever built, respectively outclassing Saturn V and SpaceX’s own Falcon Heavy by a factor of more than two and three.”

Prior to today, December 30th, SpaceX’s plan was to more or less recover Super Heavy boosters in a similar fashion to Falcon 9 and Falcon Heavy, landing them either far downrange on an ocean-based platform or returning to touch down as close as possible to the launch pad. Ever since the first iteration of SpaceX’s Mars rocket was publicly revealed in 2016, SpaceX and CEO Elon Musk have also maintained a consistent desire to land Super Heavy boosters directly on top of the launch mount after a great deal of refinement.

Launch mount recovery would require unprecedented precision and accuracy and add a new element of risk or a need for extraordinarily sturdy pad hardware. However, the benefits would be equally significant, entirely eliminating the need for expensive recovery assets, time-consuming transport, and even the time it would take to crane Super Heavy boosters back onto the launch mount from a pad-adjacent landing zone.

Instead, Musk says that SpaceX might be able to quite literally catch Super Heavy in mid-air, grabbing the booster before it can touch the ground by somehow slotting an elaborate “launch tower arm” underneath its steel grid fins. Although such a solution sounds about as complex and risky as it gets, it would technically preclude the need for any and all booster recovery infrastructure – even including the legs Super Heavy would otherwise need.

While true, catching Super Heavy by its grid fins would likely demand that control surfaces and the structures they attach to be substantially overbuilt – especially if Musk means that the crane arm mechanism would be able to catch anywhere along the deployed fins’ 7m (23 ft) length. Even more importantly, it seems extraordinarily unlikely that such a complex and unproven recovery method could be made to work reliably on the first one or several tries, implying that early boosters will still need some kind of rudimentary landing legs.

In other words, much like direct-to-launch-mount landings, mid-air-crane-catch recovery is probably not a feature expected to debut on Super Heavy v1.0.

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.

Published

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.

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.

Elon Musk and SpaceX shrugs off the trading day Wall Street feared most

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.

SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles

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.
