The privately bankrolled Dragon capsule, the first commercial spacecraft to enter orbit, docked with the International Space Station on May 25. Astronauts Donald Pettit and Andre Kuipers used the space station's robot arm to snare the Dragon after a few hours of maneuvering. The vehicle, built by the California-based Space Exploration Technologies Corporation (SpaceX), will remain at the space station for nearly a week before returning to Earth carrying research results.
