Orbital ATK’s Cygnus spacecraft will move into the vicinity of the International Space Station on Wednesday with a launch today from Space Launch Complex-41 at Cape Canaveral Air Force Station. Astronaut Kjell Lindgren would use the station’s robotic arm to grapple the Cygnus, which carries a fixture designed to work with the arm, and then pull the uncrewed spacecraft toward the Unity module, also known as Node 1. The Cygnus will be connected to the Earth-facing port on Unity where astronauts will unpack its 7,380 pounds of equipment and supplies.
