The mission originally scheduled for November 10 has been delayed for 24 hours. It is now scheduled to go off at 7:37 a.m. Saturday November 11. According to Sam Scremimi, for the International Space Station from NASA Headquarters in Washington, the reason for the 24 hour delay is that there are some time sensitive experiments aboard Cygnus and the delay will shorten the trip to the ISS by a day. The Cygnus OA-8 mission will deliver 7700 lbs. of supplies, equipment and scientific experiments to the space station which is an increase over previous missions.
Upon arrival at the ISS, Cygnus will be unloaded and used for the first time as an extension of the orbiting laboratory for an experiment featuring the SpaceTango facility’s Tangolab. TangoLab is a re-configurable general research facility designed for micro-gravity research and development. This exercise will demonstrate the ability to expand the stations capabilities for hosting experiments using the Cygnus Module. Cygnus will remain berthed for two weeks to allow the astronauts on Space Station to perform the transfer of the lab to Cygnus and then back to the station where it will remain. Once Cygnus is unberthed , a NanoRacks deployer will release 14 Cubesats, a record number for the spacecraft. Upon completion of its mission, Cygnus will perform a safe, destructive reentry into the Earth’s atmosphere over the Pacific Ocean.
