                       Part of VTXO project with 100 kg satellite and carries X-Ray optics.  | 
                  
| Description | 
                       Carries the Phase Fresnel Lenses (PFLs), and a cold gas propulsion system to provide an initial perigee raise and provide orbit maintenance maneuvers. The OSC deploys from a standard 6U canister and contains a radiation tolerant avionics system. The two spacecraft launch on a common rideshare to a highly elliptical super synchronous transfer orbit. Once deployed, the they will perform a checkout procedure after which the two spacecraft will perform a series of maneuvers to bring the two spacecraft back together. At that point, VTXO is ready to begin performing the science phase of the mission.  |
