All,

The first perigee contact for Orbit# 585 was nominal and the inertial maneuver was successful.

The SSR_Dump contact with USAK01 was a failure. At AOS, we did not see downlink and tried to command to a lower downlink data rate with no success.

We then tried to blind acq the spacecraft @160k with no success and tried again to command the downlink to 2k & to 40k with no success.

The contact was ended early and a scheduled Blind_Acq contact with HAW01 @1045z was successful to monitor the health of the spacecraft.
