Cygnus Cargo Supply Spacecraft Mated to the ISS.

The Orbital ATK Cygnus cargo craft that arrived at the International Space Station on March 26 was grappled several hours later with the station’s Canadarm2 robotic arm and installed on the Earth-facing port of the Unity module for a two-month stay. The spacecraft launched to the International Space Station on March 22 with almost 7,500 pounds of science and research, crew supplies and vehicle hardware for the crew aboard the orbital laboratory.
