A sight to behold: The Dragon, hovering above the Earth, photographed from the ISS. Later, flight engineer Tom Marshburn would capture the Dragon when it was 32 feet away from the station with the Canadarm2. Ground controllers subsequently assumed responsibility for operating the Canadarm2 and berthed Dragon to the space station.
SpaceX's Dragon fills a critical void. The manned Russian Soyuz spacecraft that carry three-person crews to and from the space station can only bring back a few hundred pounds of cargo. All other station vehicles burn up during re-entry.
