Cygnus Released From ISS After Successful Demonstration Mission
[ Watch the Video: Cygnus Completes Mission! ]
The Canadarm2 released Orbital Sciences’ Cygnus commercial craft at 7:31 a.m. EDT Tuesday after three weeks at the International Space Station. Flight Engineers Luca Parmitano and Karen Nyberg were at the controls of the robotics workstation removing Cygnus from the Harmony node then safely releasing it.
Parmitano and Flight Engineer Mike Hopkins closed the hatches and depressurized Cygnus Monday morning. On Wednesday, the Cygnus will fire its engines for the last time at 1:41 p.m. and re-enter the Earth’s atmosphere for a fiery destruction over the Pacific Ocean.
Cygnus delivered 1,300 pounds of gear on Sept. 29 when it arrived and was captured by Canadarm2 again with Nyberg and Parmitano at the controls. After Cygnus was captured and berthed to the Harmony node it successfully completed its demonstration mission to the International Space Station.
Orbital Sciences' first official commercial resupply mission is scheduled for launch in December when Cygnus on the Orbital 1 mission will launch from Wallops Flight Facility in Virginia. Future Cygnus flights will ensure a robust national capability to deliver critical science research to orbit, significantly increasing NASA's ability to conduct new science investigations to the only laboratory in microgravity.
The only other commercial resupplier to the space station is SpaceX. The private launch company has conducted two demonstration missions and two resupply missions utilizing its Dragon cargo craft.
