All,

   The SSC AUWA01 and USAK01 contacts were nominal for CMD & TLM. The Inertial maneuver was successful. The Orbit 505 Bus and Instrument ATS’s were uplinked and the command count at LOS was 232. The 18 Day timer command executed nominally and the timer was set back to 10.The APL-18 contact was not successful. We will need to redump the Orbit 503 SSR data on the 504 perigee passes. Both are scheduled @160k.
