Video: SpaceX Dragon capsule docks with International Space Station Astronauts aboard the International Space Station (ISS) captured Space Exploration Technologies' Dragon cargo ship on Friday, the first privately owned vehicle to reach the ISS. Using the station's 58-foot long (17.7m) robotic crane, Nasa astronaut Don Pettit snared the Dragon as the two spacecraft soared 250 miles (402km) over northwest Australia at 17,500mph (28,164kph). The capsule is carrying about 1,200 pounds (544 kilograms) of food, water, clothing and supplies for the ISS crew. It is due to be repacked with equipment to come back to Earth, and depart the station on May 31. Splashdown in the Pacific Ocean off the coast of southern California is expected to occur later that day.
