SpaceX Dragon 2 is a class of reusable spacecraft created by American aerospace manufacturer SpaceX as the replacement to the Dragon 1 cargo spacecraft.

The spacecraft launches atop a Falcon 9 Block 5 rocket and returns to Earth via an ocean splashdown. The spacecraft can dock itself to the International Space Station (ISS) instead of being berthed.

It has two versions; Crew Dragon, a human-rated capsule capable of carrying up to seven astronauts, and Cargo Dragon, an updated replacement for the original Dragon spacecraft.
