On May 18, 2014 at 13:26 UTC the “Dragon” unmanned supply spacecraft (CRS-3 flight) was undocked from the ISS. At the controls of the robot arm inside the space station's cupola module, American astronaut Steve Swanson gave the command to release the spaceship to begin the trip back to Earth. Swanson and Russian cosmonaut Alexander Skvortsov monitored the Dragon's departure as a series of rocket firings placed the spacecraft on course to a safe distance from the space station.
