Notes to Rover Team:
1. Sequence delivered to Sequence Flight Engineer (Mittman/Nakata)
2. Sequence to be activated by realtime command
3. MAE experiments will no longer be performed at 14:00, but 3 will be done at 08:00 each SOL

SEQUENCE IMPLEMENTATION REPORT

---

• SEQUENCE EXECUTION ISSUES:

• SEQUENCE PLAN ASSESSMENT:
  Recommendations for Downlink Assessment Team
  1. None
  Flight Rules Waived:
  1. None
  Macros Modified:
  1. None
  Incorporation of EAT Operational Constraints (this sequence)
  1. DISABLE RF Wheel Temperature Sensor
  2. Disable auto shutdown
  3. Set Modem Heat to 15 minutes; 10 minutes if following a night-time APXS)
  4. Set Modem Reheat to 5 minutes.
  5. Set alarm based wakeup on morning of Sol 21 for 08:00 LST
  6. Perform Read Memory just before last downlink session
  7. Leave X accelerometer ENABLED
  8. ENABLE Y accelerometer for long moves and waypoints, DISABLE for short, simple moves/turns.
  9. DISABLE Z accelerometer.
  10. Make sure to terminate heating at 15:00, not 15:30!
  11. Use Web_Heat_B parameter instead of Web_Heat_A with Max temp of 30C.
  12. Always command a Level 2 Health Check before shutdown.
  13. Take seperate S0055 images after each individual waypoint command.
  14. Take S0050 (Rover Movie) of each individual waypoint command.
  15. Take pre and post S0050 images at Low-Compression (3:1).
  16. (DESIRE) Take rover images as early in the morning as possible to reduce dark noise current.
  17. (DESIRE) Leave rover on until 15:45 LST to collect late afternoon thermal data, perform health check just before shutdown.
  18. Perform level 2 health check at the end of every traverse command
  19. Perform Time Sync just prior to EOD shudown.
  20. Limit image transfer after 1:00 LST (to prevent overheating)
  21. Limit each "Move Command" distance to 1 meter or less to enable gyro to be recalibrated and thereby reduce the amount of drift.
  22. Insert longer wait (10 seconds) between APXS cycle start command and APXS turn-off command (turn off devices)
  23. 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)
  24. Future soil mechanics experiments in suspected hard material should have 6 spins of 500 counts rather than 4.
