Good morning team,

The first perigee contact was nominal, and the inertial maneuver was successful. We performed the following, dump SSR (VCid2), and reset master timer. During the second perigee contact, the ground station had issues linking to the spacecraft and telemetry went stale about 15 minutes after AOS. We tried to blind acq the contact and switch to different data rates but were unable to command. Tim scheduled another contact with AUWA01 at 12:00z and that contact was nominal.

The playback files from last week have been processed and the start tracker reset time was 2024/148:19:09:34.
