SpaceX launched its new Starfall return capsule on a Falcon 9 rocket on June 23 to test controlled atmospheric reentry and splashdown capabilities. The disk-shaped vehicle, weighing approximately 4,600 pounds, is designed to provide affordable, routine access to microgravity for scientific research and in-space manufacturing.
What are the technical specifications of the Starfall capsule?
According to a U.S. Federal Aviation Administration (FAA) environmental assessment, the Starfall capsule is a disk-shaped spacecraft standing 2.5 feet (0.75 meters) tall with a diameter of 10.2 feet (3.1 meters). The vehicle consists of an aluminum “top plate” weighing about 3,090 pounds (1,400 kg) and a detachable carbon-fiber heat shield.
The internal payload bay measures 8.2 feet long, 4.9 feet wide, and 1.6 feet tall. This configuration allows the vehicle to carry roughly 2,200 pounds (1,000 kg) of cargo. SpaceX stated via X that the vehicle aims to enable routine access to microgravity for manufacturing and scientific purposes.
- Starfall: 10.2 ft diameter | 2,200 lb payload capacity
- Dragon: 13.0 ft diameter | 6,600 lb return capacity (per SpaceX specifications)
How does Starfall handle atmospheric reentry and landing?
The Starfall vehicle does not utilize a traditional propulsion system for maneuvering. Instead, the FAA assessment indicates the capsule uses an attitude control system powered by compressed inert gas, such as nitrogen. This system performs small maneuvers to point the heat shield in the correct direction during the fiery descent through Earth’s atmosphere.
Because the capsules cannot de-orbit themselves, they follow pre-planned trajectories. They rely on parachutes to facilitate a splashdown in the open Pacific Ocean. SpaceX targets a recovery zone approximately 700 nautical miles (1,300 kilometers) off the west coast of the United States, where recovery boats collect the vehicle and its cargo.
Which companies are competing in the Earth-return market?
SpaceX enters a growing sector of the space economy focused on bringing orbital products back to Earth. While SpaceX leverages the high flight frequency of the Falcon 9—which flew 165 times in 2025—other companies are targeting specific niches in the market.
California-based Varda Space has already successfully launched and landed five of its “W-series” spacecraft. These 650-pound (300 kg) vehicles function as orbital mini-factories. Meanwhile, Outpost Space is developing the “CarryAll” vehicle. According to the company’s website, the CarryAll is designed to return much larger payloads, weighing up to 22,000 pounds (10,000 kg), with high precision.
Market Payload Comparison
| Company/Vehicle | Estimated Payload/Weight |
|---|---|
| Varda Space (W-series) | 650 lbs |
| SpaceX (Starfall) | 2,200 lbs |
| Outpost Space (CarryAll) | 22,000 lbs |
What are the primary goals for Starfall technology?
The FAA document outlines two central objectives for the Starfall program. First, the vehicle is intended to enable point-to-point delivery of critical cargo through space on rapid timelines. Second, SpaceX aims to build a commercial in-space manufacturing market.
By offering “loiter on orbit” and “safe return from orbit” as a service, SpaceX hopes to support industries that require microgravity environments, such as pharmaceutical development. The company intends to use both the Falcon 9 and the upcoming Starship to launch these vehicles.
Frequently Asked Questions
Can the SpaceX Starfall capsule carry humans?
No. According to technical specifications, Starfall is designed exclusively for cargo and is not capable of carrying astronauts.
What rockets can launch Starfall?
The vehicle is compatible with both the Falcon 9 and the Starship megarocket.
Where does Starfall land?
The capsule is designed to splash down in the Pacific Ocean, roughly 700 nautical miles off the U.S. West Coast.
