Wednesday will be the berthing day for Orbital ATK’s Cygnus following today’s flawless liftoff from Cape Canaveral Air Force Station aboard a United Launch Alliance Atlas V rocket. With its solar arrays deployed for power production, the Cygnus will fly autonomously to catch up to the station as ground controllers maintain a close watch from Earth. Cygnus, loaded with 7,380 pounds of equipment and supplies, will move to within reach of the 57-foot-long space station arm. Astronauts operating the arm will grapple the Cygnus and connect it to the Earth-facing port on the Unity module so it can be unpacked and the gear inside put to use.
