Starfall is an uncrewed SpaceX capsule for bringing things made in space back to Earth. It is about 3.1 m wide, 0.75 m tall and 2,100 kg, and can carry about 1,000 kg of payload. The first demo launched on June 23, 2026; the second rides on the Falcon 9 Bandwagon-5 mission scheduled for October 20.
Summary in 3 lines
- The Falcon 9 "Bandwagon-5" rideshare, scheduled for October 20, 2026, carries many small satellites and the second demonstration of SpaceX's "Starfall" return capsule.
- Starfall is a cylinder about 3.1 m wide, 0.75 m tall and 2,100 kg, designed to bring about 1,000 kg of cargo from space to Earth.
- The goal is to return the products of microgravity manufacturing (medicines, materials). FAA documents cover two reentries into the Pacific Ocean.
Background: why is coming back so hard?
Getting to space is hard, but coming back has its own difficulty: speed. A spacecraft in low Earth orbit travels about 7.8 km per second, roughly 28,000 km/h, about 100 times faster than a bullet train. To land, that speed must drop to nearly zero.
Motion energy is "mass x speed x speed / 2". Per kilogram, 7,800 x 7,800 / 2 is about 30 million joules. That is about 7 times the energy in the same mass of TNT (about 4.2 million joules per kilogram). That energy goes into heat, from friction and from air being squeezed in front of the capsule, which reaches thousands of degrees.
So a reentry capsule needs a heat shield, a material that slowly burns away and carries heat with it, or one that barely conducts heat. Ordinary metal cannot survive.
Even after the heat, the capsule is still fast. Once the air has slowed it enough, parachutes open in stages: small ones to stabilize it, a large one to slow it to a gentle splashdown.
A return capsule therefore has four jobs: enter at the right angle, survive the heat, slow down with parachutes, and be recovered.
What happened
According to the launch database Launch Library, Falcon 9 "Bandwagon 5" (a dedicated mid-inclination rideshare) is scheduled for 10:30 UTC on October 20, 2026 from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, on booster B1085, listed as its 19th flight.
It carries dozens of small satellites for commercial and government customers, and the same listing says it also carries the second demonstration of SpaceX's Project Starfall.
The first Starfall demo launched on June 23, 2026. Spaceflight Now reported that SpaceX confirmed the capsule's deployment at 10:01 a.m. EDT. SpaceX showed neither the upper stage nor the capsule in its webcast, and has shared few details.
What is Starfall?
Starfall is an uncrewed return capsule SpaceX is developing, following the "Star-" naming of Starlink, Starshield and Starship.
Numbers, from the FAA environmental assessment as reported by Spaceflight Now:
| Item | Value |
|---|---|
| Shape | Cylinder |
| Height | about 0.75 m |
| Diameter | about 3.1 m |
| Mass (empty) | about 2,100 kg |
| Payload | about 1,000 kg |
| Total | about 3,100 kg |
| Top plate | aluminum, about 1,400 kg |
| Heat shield | carbon fiber structure, about 700 kg |
| Parachutes | 3 (drogue, pilot, main) |
It is wide and flat, like a disc, which suits slowing down by catching air over a large area.
A key feature is that it has no engine. Reportedly it has no main propulsion and cannot perform a deorbit burn; only inert-gas thrusters for orientation. It can change its attitude but not its orbit. How it is sent back toward Earth is not detailed in the public documents.
Why build it?
The FAA assessment gives two goals:
- Enable fast point-to-point delivery of cargo through space.
- Build an in-space manufacturing market by offering microgravity, vacuum, long loiter time and return from orbit as a service.
Microgravity can make things Earth cannot: very clean protein crystals, new kinds of glass. NASA's CRS-35 cargo includes research on artificial retinas and glass in microgravity (earlier article). But the products are only useful once they are back on Earth.
Dragon is one existing way to return cargo. Starfall could be another, specialized for cargo. Dragon is larger and carries people; Starfall is an uncrewed tool with a different role.
Recovery
In FAA documents the capsule is recovered in the Pacific Ocean, similar to Dragon. After reentry the top plate separates and the parachutes deploy. The FAA modified SpaceX's license for two Starfall reentries, after a final environmental assessment and a finding of no significant impact (May 2026).
My view
A flat disc with no engine looks like a design that favors being light, cheap and mass-produced. Instead of Dragon-level crew safety, it specializes in cargo delivery to cut cost, an idea similar to how reuse cut launch cost. For how to think about cost, see Is a rocket launch really expensive?.
Next question
If cargo could return from space every day, what products would be worth making there? Whether the next capsule comes back safely will be the first clue.

Status (2026-10-20): The launch time, booster number and the second demo's presence are based on the Launch Library schedule. FAA figures were checked through Spaceflight Now's report. The results of the launch and reentry are not yet known.
