Sequence 51510B:

• NO DATA
• Assume still in runout
• Last data received on Sol 15
• Assume end of day position the same as Sol 15

• ALL ROVER APIDs FOR SOL 15 and 16!!!
• Image Command 13143 (Science Image, APID 8)
  • Missing Pkts 6-33 (28 of 34 pkts)
  • SCET 7/17/97 ~10:59:46
  • Should have been received on Sol13
  • Should have been retrasmitted on Sol14
• Image Command 14088 (Ops Image, APID 25)

1. Disable auto shutdown
2. Set Modem Heat to 15 minutes; 10 minutes if following a night-time APXS)
3. Set Modem Reheat to 5 minutes.
4. Set alarm based wakeup on morning of Sol 17 for 08:00 LST
5. Perform Read Memory just before last downlink session
6. Leave X accelerometer ENABLED
7. ENABLE Y accelerometer for long moves and waypoints, DISABLE for short, simple moves/turns.
8. DISABLE Z accelerometer.

1. Take pre and post S0050 images at Low-Compression (3:1).
2. (DESIRE) Take rover images as early in the morning as possible to reduce dark noise current.
3. (DESIRE) Leave rover on until 15:45 LST to collect late afternoon thermal data, perform health check just before shutdown.

1. Perform level 2 health check at the end of every traverse command
2. Perform Time Sync just prior to EOD shudown.
3. Limit image transfer after 1:00 LST (to prevent overheating)
4. Limit each "Move Command" distance to 1 meter or less to enable gyro to be recalibrated and thereby reduce the amount of drift.
5. Insert longer wait (10 seconds) between APXS cycle start command and APXS turn-off command (turn off devices)
6. Perform WEB heating on days of low activity (i.e. no traverses) from 12:00 (noon) to 15:00 MLST with temperature setting at 30 deg and if not performing night-time APXS (should be in runout sequences)

DATA VOLUME SUMMARY (BY APID)*

NO DATA

*All data downlink on Sol INCLUDING retransmitted data.

NAVIGATION PERFORMANCE:

No Updated Report

The last reported position of the vehicle is x=3.258 m, y=1.064m, heading=285.5 degrees.

Constraints:

Y accelerometer showed continued anomalies on last level 3 health check (15155, reading + and - 0.328g's, reporting on move 15114). This supports the continued recommendation to force the y accelerometer failed.

THERMAL PERFORMANCE:

• No Updated report
• Sol 15 mid-day temperatures are 5-10 degrees warmer than Sol14, comparable to other medium activity days. Not expected to exceed mid 30's on internal boards. No FA exceedence expected. Tonight's APXS will provide additional nighttime heating so wakeup temperatures on Sol 16 will be comparable to today.
• MAE temperatures predicts (assuming no movement)- 10:00 LST: -815C, 12:00 LST: 0C, 2:00 LST: +9C
• Recommendations remain the same as previous Sols.

COMMUNICATIONS PERFORMANCE:

• No updated Report

MOBILITY PERFORMANCE:

• No updated Report
• The final rover turn should have placed the LR wheel on Scooby Doo and the RR wheel on a small rock to the right. The APXS is deployed down fully but is probably 2 cm away from soil. It is probably NOT above Scooby Doo. EOD images were not available.
  
  Daily Odometry: 1.874 m
  Total Odometry: 18.852 m
  Average Wheel Travel: 29.370 m

  Recommendations:

  Low-Compression (3:1) images pre/post S0050 were AGAIN not taken! IMP sequence request was submitted from Mobility to Rover Coordinator.

POWER PERFORMANCE:

No updated report
