SpaceX just launched a brand-new return capsule that it has been developing in the dark.
That vehicle, called Starfall, lifted off atop a Falcon 9 rocket this morning (June 23), on a test mission designed to show that it can fly in a controlled fashion and survive the fiery trip down through Earth’s atmosphere.
The demonstration flight may have caught some space fans by surprise, for SpaceX has revealed little about Starfall to date. And that air of secrecy extended through today’s launch; the company cut off its webcast about 10 minutes after liftoff, a practice usually associated with national security missions.
SpaceX provided a very brief overview of Starfall today, saying via X that the new vehicle “will enable affordable, routine access to the microgravity environment for scientific research and in-space manufacturing.”
Details about the vehicle are harder to come by — but we have some, thanks to an environmental assessment published by the U.S. Federal Aviation Administration (FAA) last month. That report looked at the potential environmental impact of two Starfall demonstration reentries, one or both of which was set in motion by today’s launch. (It’s unclear how many Starfall vehicles the Falcon 9 lofted on this initial flight.)
According to the FAA document, Starfall is a disk-shaped spacecraft that stands about 2.5 feet (0.75 meters) tall, with a diameter of 10.2 feet (3.1 m). It weighs roughly 4,600 pounds (2,100 kilograms) and can carry about 2,200 pounds (1,000 kg) of payload. The vehicle can launch on both the workhorse Falcon 9 and Starship, the megarocket SpaceX is developing to help humanity settle the moon and Mars, among other tasks.
Starfall consists of two parts: an aluminum “top plate” that weighs about 3,090 pounds (1,400 kg) and a detachable carbon-fiber heat shield. Cargo rides in the top plate, which features a payload bay 8.2 feet long, 4.9 feet wide and 1.6 feet tall (2.5 by 1.5 by 0.5 m).
For comparison, SpaceX’s Dragon capsule, which routinely flies people and cargo to and from the International Space Station, stands about 14.7 feet (4.5 m) tall, with a diameter of 13.0 feet (4.0 m). Dragon can haul about 13,230 pounds (6,000 kg) to low Earth orbit and bring 6,600 pounds (3,000 kg) back down, according to its SpaceX specifications page.
Starfall is not capable of carrying astronauts. And, in another departure from Dragon, the newly debuted return vehicle does not have a traditional propulsion system.
It has only “an attitude control system which uses compressed inert gas (for example, compressed nitrogen gas) to perform small attitude control maneuvers, such as pointing the capsule’s heat shield in the correct direction to safely reenter Earth’s atmosphere,” the FAA’s assessment reads.
“Capsules do not have the ability to de-orbit themselves and can only control their attitude,” it adds. “Individual capsules would reenter Earth’s atmosphere on a pre-planned trajectory and splash down with the assistance of parachutes.”
That splashdown — at least of the first two Starfall vehicles — will take place in the open Pacific Ocean, about 700 nautical miles (1,300 kilometers) off the west coast of the United States. Starfall, and its cargo, will then be collected by recovery boats.
SpaceX has two main goals for Starfall, according to the FAA document. The vehicle will “enable point-to-point delivery of critical cargo through space on rapid timelines” and also “create a self-sustaining commercial in-space manufacturing market by offering access to microgravity and vacuum, loiter on orbit, and safe return from orbit as a service at scale.”
SpaceX isn’t alone in pursuing these opportunities. For example, the California-based company Varda Space has already launched and landed five of its 650-pound (300 kg) “W-series” spacecraft, which are designed to be both orbital mini-factories and return capsules.
And another California outfit, Outpost Space, is developing a line of “CarryAll” return vehicles that can get very large payloads — those weighing up to 22,000 pounds (10,000 kg) — down from space with pinpoint accuracy, within 80 feet (25 m) of a target anywhere on Earth.
The CarryAll Block 3 will be a “flagship vehicle for in-space manufacturing and warehousing, Earth return, military resilience and humanitarian aid,” Outpost’s website states.
So SpaceX is not breaking new ground with Starfall. But the company is poised to play a leading role in the nascent Earth-return field, thanks to its launch dominance and vertical integration.
The Falcon 9 flew a whopping 165 times in 2025, after all, and SpaceX envisions launching Starship thousands of times per year when that massive rocket comes fully online. So it shouldn’t be too difficult for SpaceX to send hundreds of Starfall vehicles up and then back down again, delivering space-made pharmaceuticals and other high-value goods to customers around the world.
