L-42 days (February 8) – OA-6 Cygnus spacecraft nears launch readiness.
With just over a month to go before launch, technicians at the Space Station Processing Facility continue to load cargo into the Cygnus cargo module for the OA-6 mission. Over 7,700 pounds of supplies are being brought up to the International Space Station on Cygnus.
Cargo loading is completed by placing the module horizontally on a support jig that can rotate 360 degrees. When one side of the spacecraft’s interior is loaded, it is rotated 90 degrees and the process starts again.
The Cargo Module arrived at Kennedy Space Center January 9, with the Service Module arriving three weeks later on January 25.
Launch of OA-6 was originally scheduled for 3:08 am on Thursday, March 10th. However, additional processing times required the launch to be pushed back to March 20th.
It will mark the second and final Cygnus spacecraft to launch on a United Launch Alliance Atlas V rocket. Atlas was selected by Orbital ATK to launch OA-4 and OA-6 while their Antares booster undergoes return to flight preparations. OA-5 will be the return to flight of that vehicle, which is based out of Wallops Island, Virginia.
