  Incorporation of EAT Operational Constraints (this sequence)
  (Copied from Sol 17 downlink report)

  Proceed with nominal sequence planning Operational Constraints (Sol 22 Sequence):

  1. Reset APXS_DLIM before any traverse commands.
  2. Leave X accelerometer ENABLED
  3. DISABLE both the Y and Z accelerometers during all waypoints and moves to be performed on Sol 24 assuming terrain is similar to that traveled on Sol21.
  4. Recommend Risk Level 1, Laser drop out 3.
  Engineering Requests:
  1. Waypoint Navigation:
     • Continue to perform waypoint commands.
     • Take seperate S0055 images after each individual waypoint command.
     • Take S0050 (Rover Movie) of each individual waypoint command.
  2. Take pre and post S0050 images at Low-Compression (3:1).
  3. (DESIRE) Take rover images as early in the morning as possible to reduce dark noise current.
  4. (DESIRE) Leave rover on until 15:45 LST to collect late afternoon thermal data, perform health check just before shutdown.
  Operational Constraints (General):
  1. If need to perform Level 3 health checks between Sol n, 20:00 LST and Sol n+1,8:00 LST, disable lasers (i.e., never power) to prevent them from being turned on. Re-enable afterwards.
  2. Heat modem for 5 minutes prior to morning transfer of images.
  3. Terminate heating at 15:00
  4. Disable auto shutdown
  5. Set Modem Heat to 15 minutes; 10 minutes if following a night-time APXS)
  6. Set Modem Reheat to 5 minutes.
  7. Set alarm based wakeup to 08:00 LST
  8. Perform Read Memory just before last downlink session
  9. DISABLE RF Wheel Temperature Sensor
  10. DISABLE Z accelerometer.
  11. Perform Time Sync just prior to EOD shudown.
  12. Always command a Level 2 Health Check before shutdown.
  13. Perform level 2 health check at the end of every traverse command
  14. Limit image transfer after 1:00 LST (to prevent overheating)
  15. Limit each "Move Command" distance to 1 meter or less to enable gyro to be recalibrated and thereby reduce the amount of drift.
  16. Insert longer wait (10 seconds) between APXS cycle start command and APXS turn-off command (turn off devices)
  17. Perform WEB heating on days of low activity (i.e. no traverses) with no night-time APXS operations, and Runouts from 13:00 (noon) to 15:00 MLST.
  18. Use Web_Heat_B parameter with Max temp of 30C.
  19. Future soil mechanics experiments in suspected hard material should have 6 spins of 500 counts rather than 4.

  Incorporation of Operational Constraints
  1. All taken into consideration
