NAVIGATION PERFORMANCE:
Perform soil experiment and adjust vehicle position to APXS Chimp.
The vehicle performed all of the navigation commands sent for the day.
However, due to weather in Canberra only paratial command telemetry
was received. Based on the subsequent health check and image telemetry,
it appeared that the vehicle had reached its final destination without
erroring out. There was no confirmation of whether the APXS contacts
were triggered or not since the telemetry data was lost during
transmission to Earth. There was not enough information to determine
the status of the Y, but it probably was in good standing since the
vehicle reached its destiation without erroring out (?).

SUBSYSTEM REPORTS
ACTIVITIES:
Report pending
Report Pending
Report Pending
With the exception of the battery, which was depleted on SOL 56, the remainder
of the Power Subsystem is in good health. The power subsystem continues to
operate only on solar power. Additional health checks from the SOL 76 runout
telemetry which had embedded health checks in the hold com period of the APXS
measurement as refered to in the Sol 69 report continue to show a higher
current draw for the APXS than formerly reported by the APXS PI. This could
account for the apparent early depletion of the batteries. This will be
investigated further. There were no new operational problems noted in the
telemetry from SOL 77.
TELEMETRY PROCESSING ANOMALIES
Bad spooler file in TDS. Had to manually query around the bad spooler file, combine the (2) tds.out files, resort them by SCET, and manually generate all associated data products.
