According to SpaceX's official page, Dragon can carry up to 7 passengers to and from Earth orbit. It is 8.1 m tall and 4 m in diameter, with 9.3 cubic meters in the crew section and 37 cubic meters in the trunk. It launches up to 6,000 kg of cargo and returns up to 3,000 kg. SpaceX calls it the only spacecraft currently flying that can return significant amounts of cargo to Earth.

Falcon 9 is a rocket. Dragon is the spacecraft it carries on top. We summarize what SpaceX's official Dragon page confirms (checked 2026-10-16).

The conclusion: up to seven people, and cargo can come back

The page says (summary):

  • Dragon can carry up to 7 passengers to and from Earth orbit, and beyond.
  • It is "the only spacecraft currently flying that is capable of returning significant amounts of cargo to Earth" and the first private spacecraft to take humans to the space station.
  • In 2020, SpaceX returned America's ability to fly NASA astronauts to and from the ISS on American vehicles for the first time since 2011.

Height8.1 m (26.7 ft)
Diameter4 m (13 ft)
Spacecraft (pressurized) volume9.3 m³ (328 ft³)
Trunk volume37 m³ (1,300 ft³)
Launch payload mass6,000 kg (13,228 lbs)

[A note for beginners]

The pressurized section holds air and carries people and environmentally sensitive cargo. The trunk carries unpressurized cargo.

The trunk: cargo and solar panels

  • The trunk carries unpressurized cargo and supports the spacecraft during ascent.
  • One half is covered in solar panels that provide power in flight and on station.
  • It stays attached until shortly before reentry.

Thrusters and launch escape

  • Draco: 16 thrusters for attitude control, orbit adjustment and so on; each produces 400 N (90 lbf) in vacuum.
  • SuperDraco: 8 thrusters that power the launch escape system.

Parachutes

The page says Dragon has two drogue parachutes to stabilize it after reentry and four main parachutes to decelerate it further before landing.

The parachute sequence: two drogues, then four mains (AI-generated concept diagram based on the official page)

How does the emergency escape work?

Eight SuperDraco thrusters power a launch escape system.

Is Dragon a rocket?

No. It is a spacecraft launched on a rocket (Falcon 9).

Summary

  • Dragon carries up to 7 people; 8.1 m tall, 4 m in diameter.
  • Cargo: 6,000 kg up, 3,000 kg back. Trunk 37 m³.
  • 16 Draco and 8 SuperDraco (escape) thrusters; 2 drogue and 4 main parachutes.
