OSC (Optics Space Craft, Virtual Telescope for X-Ray Observations, VTXO)

Name OSC (Optics Space Craft, Virtual Telescope for X-Ray Observations, VTXO)
Type CubeSat
Units or mass 6U
Status not launched, expected in 2024
Organisation New Mexico State University
Institution University
Entity Academic / Education
Nation US
Partners University of Maryland, Space Dynamics Laboratory, NASA Goddard Space Flight Center

Part of VTXO project with 100 kg satellite and carries X-Ray optics.


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.
