I'd like to hold a brief FRB at 10:30 EDT. Zoom info attached.

Some initial talking points:

Do we want to load the orbit 540 ATS? Perhaps a test time-tagged command uploaded first?
Should we try to set the spacecraft clock or avoid doing that?
Running order for activities during next contact

Future planning

Thanks,
Nigel

All,

    The AUWA01 pass @00:30 I noticed that the spacecraft time was incorrect. The clock was reporting 1970/01/01 00:00:00. It was not incrementing. The stored commands were executing on time and the ACS time  was correct. All the telemetry points had the timestamp 1970/01/01 00:00:00. Hoping that that it was just a ground system issue post SSR dump I instructed SSC to fail over to string 1 from string 2. I saw the same timestamp issue on string 1. I noticed  that in the playback post pass that the time stopped incrementing @2021:236:07:50:04 (24 Aug21). No commands were executing at that time.  Overall the spacecraft looks nominal.  The next planned pass is in the morning USHI01 @16:00 – 17:00 gmt.
