Cygnus rendezvous aborted due to data link issue

A commercial Cygnus cargo spacecraft, owned and operated by Orbital Sciences Corp., aborted its rendezvous with the International Space Station on Sunday after the automated spaceship encountered a data glitch before commencing final approach. The Cygnus resupply vehicle flew about 2.5 miles below the space station and will set up its trajectory to try to approach the complex again early Tuesday. Loaded with more than 1,500 pounds of food, computer equipment, spare parts and student experiments, the unmanned cargo freighter was supposed to close in on the space station with GPS and laser navigation aids and move into position about 30 feet below the outpost, close enough for the station's robotic arm to reach out and grapple the free-floating Cygnus spacecraft.
