The Expedition 46 crew took out the trash recently when it released the Orbital ATK Cygnus spacecraft from the grips of the International Space Station's Canadarm2 robotic arm. Cygnus was filled with roughly 1.5 tons of trash and discarded gear before the hatches were closed. Ground controllers then remotely guided the Canadarm2 to grapple Cygnus and detach it from the Unity module. NASA astronauts Scott Kelly and Tim Kopra commanded the Canadarm2 to release Cygnus Feb 19, at 7:26 a.m. EST when it began gracefully departing the vicinity of the station. Cygnus ultimately burned up during reentry through the Earth's atmosphere on Saturday, Feb 20. This was Orbital ATK's fourth commercial resupply mission.
