OA-9E Cygnus Might Reboost ISS

Chris Gebhardt, for NASASpaceflight, on a very cool aspect of the upcoming OA-9E mission:

Moreover, and quite excitingly, the OA-9E Cygnus might be the first U.S. commercial vehicle to reboost the orbit of the International Space Station.  Speaking to the NASA Advisory Council last month, Ms. Gatens related that there is a potential Detailed Test Objective (DTO) in work for OA-9E to use Cygnus’ thrusters to perform an ISS reboost.

If the DTO is approved and executed, Cygnus will become the first U.S. spacecraft to perform a reboost of the ISS since the Space Shuttle fleet was retired seven years ago.
