All,

   The spacecraft is nominal. The Inertial maneuver was successful. Orbit #553 ATS was uplinked. We changed the Hi sweep table to normal sweep. The spacecraft clock was updated and the 18 day timer was reset. We did have some dropouts during the ssr dump pass. The antenna control software crashed a couple times. I have requested a DR for the contact. We plan to redump the missing data on the next set of perigee contacts.

Tasks Accomplished:

Set Spacecraft clock

Reset the 18 Day Timer

Reset FDC totals

SSR Dump -> Dump New
