  1. None
  Macros Modified:
  1. None
  Incorporation of EAT Operational Constraints (this sequence)
  (Copied from Sol 17 downlink report)

  Proceed with nominal sequence Operational Constraints (Sol 18 Sequence):

  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 16 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.
  Engineering Requests:
  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.
  Operational Constraints (General):
  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)

  Incorporation of Operational Constraints
  1. All taken into consideration
