All,

   The perigee contacts were nominal. The inertial maneuver was successful. The SSR was dumped. During the Flight Computer reset recovery we had sockets fail during an ATS upload. We determined which commands made it onboard and created a Version #2 ats for Orbit 548. The ATS’s  Orbit 548 Version #2 and Orbit 549 were uplinked.  

Tasks accomplished:

CAR # 1208 Orbit 548 Version #2 ATS uplink

    IBEX_2021_319_o0548a_V002 76 Cmds

CAR # 1209 Orbit 549  ATS uplink

    IBEX_2021_329_o0549a_V001 88 Cmds
