SpaceX outfits Starship, Super Heavy with dozens of Raptor engines

Published

on

New photos shared by SpaceX show that the company has nearly finished installing a total of 39 upgraded Raptor engines on a new Starship and its Super Heavy booster.

Those prototypes – known as Ship 24 and Booster 7 – could be tasked with supporting Starship’s first orbital launch attempt sometime later this year if both make it through upcoming test campaigns without major issues. Whether that’s a probable outcome is still uncertain but recent progress suggests that it won’t take long for the prospects of both prototypes to shift into clearer focus.

After several rounds of proof testing and two trips to and from SpaceX’s Starbase, Texas orbital launch site (OLS) in March, April, and May, Super Heavy Booster 7 (B7) made its third trip to the pad on June 23rd.

“SpaceX used the six weeks Booster 7 spent back in a factory assembly bay to finish installing aerocovers, surfaces known as chines or strakes, car-sized grid fins, Starlink internet dishes, and – most importantly – 33 upgraded Raptor V2 engines. Combined, Booster 7 could produce up to 7600 metric tons (~16.8M lbf) of thrust at or before liftoff. Crucially, SpaceX also finished installing most of Booster 7’s Raptor heat shield in the same period, completing in six weeks work that took Booster 4 closer to half a year. With its heat shield and all 33 Raptors mostly in place, Booster 7 should be ready to kick off static fire testing almost as soon as it’s installed on Starbase’s orbital launch mount.”

Building, qualifying, shipping, and installing 33 new Raptor 2 engines on Super Heavy B7 was already an impressive achievement and produced the most (potentially) powerful rocket booster ever assembled. On July 2nd, a pair of photos published by SpaceX showed off Booster 7’s nearly-finished engine section and simultaneously revealed that the company has finished installing all six of Starship S24’s Raptor engines – and even part of the ship’s aft thermal protection.

Differences are already visible between Ship 24 and Ship 20, the only other Starship prototype to have six Raptors installed. The most notable change is the addition of a metal framework that covers the entire breadth of the ship’s aft – most likely destined to support flat sections of insulation and thermal protection that will partially seal off sensitive engine, plumbing, pressure vessels, and avionics components located inside Starship’s aft. That extra shielding should help limit the extreme conditions that hardware will be subjected to during ground testing and, perhaps, in flight.

Super Heavy Booster 7 has already completed a significant amount of testing, including four cryogenic proofs (cryoproofs) and one Raptor thrust simulation test. Since its third return to the pad, SpaceX has several more ambiguous tests, none of which appeared to involve cryogenic propellant loading. It’s possible that those tests focused more on Booster 7’s pressurization system, perhaps filling its tanks with the hot oxygen and methane gases it will eventually use to pressurize its tanks. It’s likely that SpaceX wants to put Booster 7 through at least one successful wet dress rehearsal – using real liquid methane and oxygen propellant – before attempting to static fire any of its 33 Raptors. Booster 7’s aft thermal protection system also isn’t entirely complete, so technicians will need to finish installing several more panels before any static fire testing.

Alongside B7, Starship S24 has completed a good amount of cryoproof and Raptor thrust simulation testing, which it survived without any irreperable issues. The ship was then returned to an assembly bay on June 9th, where where workers have been installing heat shield tiles, finalizing the ship’s engine section, and completing dozens of other less visible closeout tasks. SpaceX also recently finished modifying one of its two suborbital test and launch mounts for Starship static fire testing, leaving the other mount semi-permanently modified for cryoproof and thrust simulation testing of future prototypes.

SpaceX has requested permission for road closures – each a potential 12-hour test window – on July 5th, 6th, 7th, 11th, and 12th.

The Boring Company’s latest Tesla tunnel truck mod “fits like a glove”

The Boring Company has modified a Tesla powered tunnel truck to carry freight containers underground.

The Boring Company has found a second job for the Tesla hardware it already runs underground. In a post on X, Elon Musk’s tunneling company showed its latest Prufrock Liner Truck modified to carry a standard 20 foot shipping container. “Using TBC tunnels to transport freight,” the company wrote. “The latest Prufrock Liner Truck (using Tesla Model 3 batteries and drive units) has been modified to carry a standard 20′ shipping container. Fits like a glove!”

The photo shows a red container sitting on a long, low white chassis parked outside, with drive hardware visible at one end. The Boring Company did not say where or when freight hauling would start, which customers it has in mind, or how many trucks it is converting.

Until now, the liner trucks have hauled concrete. Teslarati reported in August on Liner Truck 3, which uses Model 3 battery packs and drive units to move more than 22,000 pounds of precast tunnel segments to the boring machine. It has 28 miles of range, tops out at 12 mph, and is piloted remotely from the company’s operations center in Texas. The freight version appears to be the same platform with a different bed, and The Boring Company has not said whether it will also be remotely piloted.

Freight has been on the company’s menu for years. When TBC updated its product lineup in 2021, its freight tunnel was described as sized to fit a standard shipping container, “barely.” The company later used the idea at Tesla’s own factory, where Prufrock 3 dug a tunnel to Giga Texas that now moves finished Cybertrucks away from the production line.

The Boring Company closed a $3 billion Series D in September at a $23 billion valuation, and Teslarati has covered how that money is tied to a UAE tunneling push and a faster Nashville build. In Nashville, Prufrock MB1 and MB2 are mining at the same time, and a third machine is expected to launch in late October. Each machine needs a steady supply of liner trucks, so any design that works for segments and containers alike gives the company more use out of the same Tesla parts.

The Vegas Loop remains the only Boring Company system open to the public, and it moves passengers in Tesla vehicles. A freight service would be a separate product, and the post gave no indication that one is close to launch. For now, it is a truck, a container and a short caption saying they fit together.

Elon Musk will give ‘every kid in America’ a SpaceX share in 2027

Published

Elon Musk said he is planning to give “every one of his SpaceX shares to every kid in America” in 2027, stating that “this will be the first of many.”

SpaceX went public earlier this year, and its stock price has been relatively stable since leveling off shortly after its IPO. Based on its current price, it’s a gift of just over $10 billion to children across the United States.

It appears to be closely related to President Donald Trump’s bank accounts for children, which were set up earlier this year as Trump Accounts.

Just hours earlier, Anthropic had announced the establishment of its Anthropic Public Benefit Fund, “a new wholly-owned entity dedicated entirely to public benefit.” Musk responded by stating he recommended “giving the shares directly to the public,” and that he would be doing it that way.

Just a little bit later, Musk said children across the U.S. would be getting a share from him:

There are roughly 70 million children, meaning someone under the age of 18, in the United States, according to the Federal Interagency Forum on Child and Family Statistics. Musk’s ownership of SpaceX stock shows he has around 849 million Class A shares of SpaceX stock, according to filings with the SEC.

Elon Musk reveals why Boring Co’s biggest East Coast project never happened

Elon Musk revealed in a post on X that “Permits were impossible to get,” explaining the fate of The Boring Company’s most ambitious East Coast proposal.

The comment responded to a query about what became of his July 20, 2017 announcement that he had “just received verbal govt approval” for an underground Hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, D.C., capable of carrying passengers from the Big Apple to the Nation’s Capital in just 29 minutes.

The Boring Company receives verbal ‘approval’ to build NY to DC Hyperloop tunnel

The 2017 post, which envisioned city-center stations and multiple elevators in each city, sparked immediate scrutiny. Local and state officials in New York, Philadelphia, Baltimore, and D.C. said they had no knowledge of any approval. A White House spokesperson confirmed only “promising conversations” about the transformative infrastructure.

Musk clarified shortly after that there was “still a lot of work” to do for formal approvals.

Limited progress followed, as Maryland Governor Larry Hogan’s administration issued a conditional utility permit and supported work near Fort Meade. In 2018, Washington, D.C., granted a preliminary permit for site preparation and excavation on a vacant lot at 53 New York Ave. NE in the NoMa neighborhood, which The Boring Company said could become a station.

A draft environmental assessment for a D.C.-Baltimore segment was released in 2019. Yet, by April 2021, the company had removed the project from its website, and the Federal Highway Administration reported receiving no indication of further interest. Communication with Maryland officials had ceased.

The full corridor would have required coordination among the District of Columbia, Maryland, Pennsylvania, New York, the Federal Highway Administration, the Army Corps of Engineers, the National Park Service, and other agencies.

Environmental reviews under the National Environmental Policy Act, utility clearances, and approvals for novel infrastructure added to the overall complexity of the project and its approval.

Speculation on the permitting barriers centers around a few factors, but a multi-state, multi-level route involving unproven high-speed vacuum-tube technology inherently triggers exhaustive safety, environmental, and engineering reviews that can stretch for years, even for conventional projects.

There are also other elements, of course, like officials who may face political exposure if a privately funded, untested system encountered anything such as cost overruns, delays, or safety issues. On the outset of this project, there were limited things such as engineering plans or demonstrated technology maturity, which also added to the potential skepticism.

The East Coast vision for Boring Co., once framed as a privately funded revolution that could reshape Northeast travel, quietly ended without construction of the promised network. Musk’s recent statement frames the outcome as a regulatory impasse, unfortunate but not unexpected.
