It stays on the ISS while it is emptied and loaded for the return trip. Dragon is the only vehicle with a substantial down mass capability (3000kg) so it can return with things that need fixing and completed experiments etc. Shuttle is retired and Progress, ATV, HTV and Cygnus are one way trips so only good for taking out the garbage. Soyuz is full of people. They set Dragon free with the arm, Dragon departs, does a de-orbit burn, jettisons the trunk (with the solar arrays), re-enters the atmosphere and parachutes down into the ocean and is recovered. |
