OA-7 Cygnus unberthing

The S.S. John Glenn OA-7 Cygnus cargo spacecraft will be unberthed after three months berthed to the International Space Station. It will then spend a week or so in a free-flight mode in order to perform the SAFFIRE III experiment. Afterword, the data will be downlinked to the ground before the craft is commanded to de-orbit and burn up over the Pacific Ocean.
