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.

SpaceX is launching a secret spacecraft that could change how things are made in space

SpaceX’s secret disk-shaped Starfall capsule is targeting a market no reentry vehicle has cracked.

Published

on

By

SpaceX is targeting Tuesday, June 23 for the first flight of Starfall, a reentry capsule the company has developed almost entirely in private. The Falcon 9 launch window opens at 6:43 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available the same time on June 24. SpaceX has made no public announcement about the vehicle, only providing launch details. Everything known about it has come through FAA and FCC regulatory filings.

What makes Starfall different starts with its shape. Rather than the traditional cone used by Dragon and every other cargo return capsule in operation, Starfall is a flat disk that measures roughly  10.2 feet (3.1 meters) wide and just 2.5 feet (0.75 meters) tall, and weighing 4,630 pounds (2,100 kg) and capable of returning up to 2,200 pounds (1,000 kilograms) of payload from orbit. The disk geometry maximizes structural efficiency and payload volume relative to mass, and the heat shield mechanically jettisons just before splashdown, allowing recovery teams to retrieve both the capsule and the shield separately from the Pacific Ocean.

The difference with Starfall from existing competitors, such as Varda Space Industries, which has largely built the orbital manufacturing market and returns heavy payloads per flight is that Starfall’s specification is roughly 30 times more per mission, and is designed to be mass-produced and launched on either Falcon 9 or Starship. That combination of volume and launch access is something no standalone startup can replicate, and it puts SpaceX in direct competition with the companies that currently pay it to reach orbit.

SpaceX to launch military missile tracking satellites through new Space Force contract

The intended market is orbital manufacturing: pharmaceuticals, protein crystals, semiconductors, and advanced optical fiber that physically cannot be produced in the presence of gravity. FAA documents describe Starfall’s long-term purpose as building a “self-sustaining commercial in-space manufacturing market” and as a potential successor to the industrial capabilities of the International Space Station, which is set to retire in the late 2020s. Military rapid global cargo delivery is a parallel application under active discussion with the Pentagon.

The reason some industries seek manufacturing in space comes down to gravity. On Earth, gravity causes materials to settle, separate, and deform during production. In microgravity, those constraints disappear.

SpaceX’s already controls launch access, which means it currently functions as the landlord for every competitor in the orbital manufacturing return space. Starfall converts that landlord position into vertical ownership, and it would no longer just carry other companies’ capsules to orbit, but rather operate the capsule, own the return logistics, and capture the service revenue directly. Viewed alongside Starlink, Colossus, and the xAI merger, Starfall fits a consistent pattern: SpaceX identifying infrastructure layers that others depend on and moving to own them outright. Orbital manufacturing return is the next layer on that list.

If Tuesday’s reentry, parachute sequence, and recovery demonstration goes as planned, the second FAA-approved test flight follows. A successful pair of demos would position SpaceX to begin offering Starfall as a commercial service, likely first to pharmaceutical and materials science customers before scaling toward the military and broader manufacturing segments.

Tesla Semi spotted with ground truth validation equipment as launch looms

The Tesla Semi was spotted mounted with ground truth validation equipment as the company nears its looming launch. The Semi is Tesla’s Class 8 all-electric truck, and has been utilized in its earlier stages by many companies like PepsiCo. and Frito-Lay, who have been using it in a pilot program.

The Semi was spotted in Sunnyvale, California, and sports a typical ground truth validation unit that Tesla routinely uses on its vehicles. Ground truth validation is essentially the process of training supervised algorithms to ensure they can perform reliably. Tesla typically performs this on vehicles that are being released soon:

The Semi being spotted with this type of validation rig is important because it means the company is working on solidifying a Full Self-Driving model for its commercial vehicle offering. This would be a massive development for not only Tesla but also the logistics industry as a whole.

There are strict regulations on driving hours for commercial truck drivers, and autonomy is a way to potentially combat these issues. FSD is already a widely effective way that owners of typical passenger vehicles take stress out of travel. Even launching a semi-autonomous platform for truck drivers to use to increase safety, reduce fatigue, and increase productivity would be a huge development.

Tesla Semi gets strange-but-understandable comparison from Jay Leno

The Semi has already proven to be an ideal solution for companies that use commercial logistics. It has increased efficiency and reduced operating costs for many companies that have been able to use it in pilot programs.

There are expected to be some bumps along the way. Tesla saw some challenges with FSD on the Cybertruck, as it had never had a vehicle with cameras at that height, so some of the features with FSD were not immediately available. Just a week ago, Tesla launched Actually Smart Summon (ASS) for Cybertruck, nearly three years after the vehicle was first delivered to customers.

President Donald Trump unveiled an upgraded Boeing 747-8 at Joint Base Andrews on June 19, 2026, describing the Qatar-gifted aircraft as an interim Air Force One equipped with advanced communications systems, including Starlink, Elon Musk’s SpaceX satellite internet service.

The plane, valued at around $400 million and modified for presidential use, serves as a bridge until the delayed VC-25B replacements arrive. Trump highlighted its luxury features and new technology during remarks to service members.

Trump stated:

“We have communication equipment up there that nobody’s ever seen before. It’s the highest level and, uh, including Starlink. My friend Elon is going to be very happy, but, uh, Starlink and we have, uh, four or five different sets of double and triple communications like people haven’t seen.”

He added:

“And it represents what can happen with hard work, innovation, and aggressive timelines because we did this quickly and yet there’s never been communication like is on this plane.”

The aircraft features a redesigned red, white, and blue livery and has been outfitted with Starlink satellite connectivity alongside other secure systems.

Trump praised the plane’s uniqueness, calling it among the world’s most luxurious. The gift from Qatar and subsequent modifications have drawn attention, with the jet positioned as a solution for presidential travel. It is expected to support operations, including potential ceremonial roles such as Fourth of July flyovers.

The event marked the formal introduction of the converted jet, which will help maintain capabilities while the primary Air Force One fleet undergoes modernization. Defense observers note the inclusion of commercial satellite technology like Starlink as part of efforts to ensure resilient communications, crucial to keep the country running as the President is in the sky.

President Trump’s comments underscored appreciation for rapid upgrades and innovation in equipping the aircraft. The plane remains a U.S. government asset and is slated for eventual transfer related to presidential library purposes after its service.
