Dragon gave a thorough demonstration of its manoeuvring capabilities before being allowed to approach the Space Station. At a distance of 250 m, ground control gave the go-ahead to approach the Station’s safety zone.
Dragon cautiously approached for 2.5 hours and then stopped 10 m out. From there, André and NASA astronaut Don Pettit took over and captured the vessel using the Station’s robotic arm.
Unlike ESA’s Automated Transfer Vehicle or Russian Soyuz and Progress ferries, Dragon is not designed to dock automatically with the Station. It relies on astronauts using the long arm to grab the spacecraft and move it safely into position for temporary berthing to one of the Station ports.
