  Incorporation of EAT Operational Constraints (this sequence)
  (Copied from Sol 27 downlink report)
  1. REMOVE explicit heating of modem prior to morning image transfer (superseded by maximum reheat temperature setting in "general constraints")
  2. Continue to DISABLE hazard avoidance for stall conditions/hazards during Sol 27.
  3. Leave X accelerometer ENABLED
  4. Leave the Z accel DISABLED
  5. DISABLE the Y accelerometer during waypoints and moves at risk level 1. ENABLE Y accel for waypoints and moves at risk level 2
  6. Enable hazard avoidance using sensors, contacts, and laser proximity, and perform each waypoint command only once
  7. If possible, health checks should not be skipped as a result of traversable hazards
  8. Before beginning traverses, should back up a little (~ 10 cm) to enable lasers to detect hazards which may be very close to the front of the rover. UNMASK contact sensors for this move. May want to then move forward ~ 1 cm, with contact sensors MASKED to remove any contact that may have been made during the previous backward move. Then UNMASK all contact sensors and plan subsequent waypoints.
  9. 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.
  10. Take pre and post S0050 images at Low-Compression (3:1).
  11. (DESIRE) Take rover images as early in the morning as possible to reduce dark noise current.
  12. (DESIRE) Leave rover on until 15:45 LST to collect late afternoon thermal data, perform health check just before shutdown.
  13. Mask all errors (except INVALID CMD) immediately prior to "Read Mem" of persistent state table. Unmask accordingly immediately afterwards.
  14. Set Modem Reheat to 5 minutes and maximum modem reheat temperature 30 deg.
  15. 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.
  16. Terminate heating at 15:00
  17. Disable auto shutdown
  18. Set Modem Heat to 15 minutes; 10 minutes if following a night-time APXS)
  19. Set alarm based wakeup to 08:00 LST
  20. Perform Read Memory just before last downlink session
  21. DISABLE RF Wheel Temperature Sensor
  22. DISABLE Z accelerometer.
  23. Perform Time Sync just prior to EOD shudown.
  24. Always command a Level 2 Health Check before shutdown.
  25. Perform level 2 health check at the end of every traverse command
  26. Limit image transfer after 1:00 LST (to prevent overheating)
  27. Limit each "Move Command" distance to 1 meter or less to enable gyro to be recalibrated and thereby reduce the amount of drift.
  28. Insert longer wait (10 seconds) between APXS cycle start command and APXS turn-off command (turn off devices)
  29. 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.
  30. Use Web_Heat_B parameter with Max temp of 30C.
  31. 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
