Despite a number of technical hurdles, SpaceX CEO Elon Musk believes that the company’s next-generation Starship spacecraft could eventually be capable of pad aborts in the event of a Super Heavy booster failure before liftoff.

For a vehicle as large and heavy as Starship, this would necessitate a number of compromises, but would undoubtedly serve as a major confidence-booster for prospective passengers in lieu of an established record of reliability. If Starship were capable of pad aborts like the company’s Crew Dragon spacecraft, high-profile and high-value customers like NASA and other space agencies could be far more willing to place astronauts and payloads on what they perceive to be a bizarre but high-performance launch vehicle.

Although SpaceX would almost certainly prefer that Starship and Super Heavy skip the first half of Falcon 9’s life cycle (marked by two catastrophic failures), building a new launch vehicle – particularly one with all new materials, engines, and production processes – is extremely challenging, and failures are to be expected as kinks are worked out.

On the plus side, after several lessons were learned the hard way, SpaceX has demonstrated that it can build an extremely reliable launch vehicle. Since its last catastrophic failure in September 2016, SpaceX has successfully completed 49 launches of Falcon 9 and Falcon Heavy in barely 2.5 years, compared to 29 launches (with 2 failures) from 2010 to 2016. In short, SpaceX has simultaneously proven that it can beat almost any other single provider’s launch cadence and do so with impressive reliability, all while pushing the boundaries of reusable rocketry and constantly upgrading flight hardware.

Destroying customer payloads remains unacceptable, but the ultimate success of SpaceX’s Falcon launch vehicle family – at the cost of two operational failures – is undeniable. With Starship and Super Heavy, SpaceX thankfully has several new advantages, owing to its spectacular success over the last few years. With the fruit of major fundraising in hand, an independent F9/FH launch business humming along, and the freedom to pursue significant R&D projects on its own dime, SpaceX may be able to stomach one or several Starship/Super Heavy failures and do so during internal missions.

By accepting possible (and probable) vehicle failures during development and insulating SpaceX’s external customers from any associated risk, the company should be able to develop Starship and Super Heavy in exactly the ways it wants to.

Hence CEO Elon Musk’s indication that SpaceX “is not planning for pad abort with early Starships”. In short, adding the ability for pad aborts to Starship would/will be a major challenge. Assuming a dry mass of 100 tons (220,000 lb) and a wet mass of 1000-1200 tons (2.2M-2.7M lb), Starship’s six planned Raptor engines – capable of producing up to ~1200 tons of thrust at sea level – could be barely enough to lift a fully-fueled spacecraft. In pad abort scenarios, the rocket booster would be suffering some sort of catastrophic failure, if it wasn’t already mid-explosion. As such, getting far away from said explosion as fast as possible is the name of the game, particularly if the priority is ensuring passenger/astronaut survival.

Starting a high-performance liquid rocket engine fast enough to make an abort possible is also a major challenge, though Musk says that Raptor could be capable of extremely fast start-ups in emergency scenarios. Assuming that Raptor can somehow be ignited from standstill in less than a second (preferably 0.1-0.5s) and would still be able to ignite a second time for a soft landing, SpaceX could technically give Starship the thrust-to-weight ratio needed to quickly escape a Super Heavy failure by reducing the propellant load. With the minimal propellant needed to safely reach a stable low Earth orbit (LEO) during crewed Starship launches, SpaceX would have to lean almost exclusively on rapid orbital refueling, but the combination might be enough to ensure that Starships can abort at almost any point during launch.

It’s extremely unlikely that SpaceX will pursue this capability during the prototype phase, but it may not be out of the question for the first crewed mission(s) of finalized Starships.

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.
