VTXO: Virtual Telescope for X-ray Observations
VTXO is a potential SmallSat precision formation flying mission using an OpticsSat with X-ray Phase Fresnel Lens (PFL) Optics and a DetectorSat with an X-ray camera forming a 1km focal length X-ray telescope with 55 milli-arcsecond(mas) angular resolution and 8 arcsecond FoV. VTXO development was supported under a 2018 NASA Astrophysics Science SmallSat Studies proposal.
