SUMMARY REPORT

Wakeup:

The rover woke up at 07:01:53 LTST via alarm clock (probably saved us from getting a set of bad A/D readings).
Wakeup Health Check
- TBD
Lander X axis pointing at 155.75 deg from North

Sequence 50110W:

Telemetry not received on Sol 1, up to an including several commands past the end of nominal sequence execution, were received.
Data was apparently buffered on rover when comm with lander lost.
31,491 bytes of sequence data received. Coincides with amount of EEPROM available for buffering data (32K)
All indications are that rover continued to perform runout or sequence but had no place to buffer the data.
Accelerometer failure count back to "GOOD".

Sequence 50240T:

Received telemetry for consecutive commands up to command 2543 (no skipped commands until that point)
Rover executed unstow command with error 1C08 (Bad differential potentiometer in Unstow) and F07 (failed navigation command)
It was assessed that the unstow was successfully executed despite error based on bogie positions and latch test data
Recommendation is to continue with ramp egress

Sequence 50250V:

Sequence executed nominally with no errors reported
Last command received was 2679 (move) and then the telemetry stream suddenly ceased
Visual confirmation of complete ramp egress

RETRANSMIT REQUESTS

NONE

SUBSYSTEM REPORTS

NAVIGATION PERFORMANCE:

C&N subsystem components essentially all performing as expected.

Accelerometer current appears to be back to normal (~40 mA).
CCD current still higher than expected.
Image exposure times on all three cameras ~500 msec (as predicted)!
Gyro drift half way down ramp is only 2.0 degrees! (1 deg/min ... roughly within spec of device).
No constraints to impose upon sequence planning at this point in time.

THERMAL PERFORMANCE:

Thermal subsystem components all performing as expected.

No constraints to impose upon sequence planning

COMMUNICATIONS PERFORMANCE:

Performance initially good. Late in day comm link with lander appears to have abruptly died.

Link drop out still unexplained. However, suspect it is related to a heating problem.
Request the modem reheating and modem heating be disabled to keep modem as cold as possible.

MOBILITY PERFORMANCE:

Mobility subsystem components all performing as expected.

Imp images verified successful latch of left side.
Rear wheel motor currents trajectories and bogie/differential position trajectories confirm that Unstow successful despite error report indicating that differential did not reach expected value.
Rover Movie and EOD image confirms rover on surface.
No constraints to impose upon sequence planning.

POWER PERFORMANCE:

Power subsystem components all performing as expected.

Battery usage data will have to monitored manually due to initial A/D readings all being "FF".
No constraints to impose upon sequence planning at this point in time.

TELEMETRY PROCESSING ANOMALIES

Running LabView version 3.0 until version 4.0 can be reviewed by George Wells.
