MISSION SEQUENCE PLANNER REPORT

Notes to Rover Team:
- Sequence delivered to Sequence Flight Engineer (Mittman/Salvo)
- This sequence is very heavy on imaging. There is very little margin in traversing to the final locations before IMP end-of-day imaging
- Downlink report does not explicitly request 5 minute modem heating before morning images. If this is necessary, PLEASE STATE EXPLICITLY.
- Sol 22 sequence is planned to include overnight level 3 health checks through midnight. If there are any constraints on this, please present this at crossover.

Incorporation of EAT Operational Constraints (this sequence)
- Future runouts and low activity days should have battery heating start at 13:00 LST instead of 12:00 LST.
- Leave X accelerometer ENABLED
- DISABLE both the Y and Z accelerometers during all waypoints and moves to be performed on Sol 21 (assuming plan is to get to Souffle). Differential, Bogie, contact, and proximity sensors should be more than sufficient to safe the vehicle based upon analysis of the terrain images.
- Recommend Risk Level 1, Laser drop out 3.
- Use Web_Heat_B parameter with Max temp of 30C.
- Waypoint Navigation:
- Perform several PLEASE!
- Take seperate S0055 images after each individual waypoint command.
- Take S0050 (Rover Movie) of each individual waypoint command.
- Take pre and post S0050 images at Low-Compression (3:1).
- (DESIRE) Take rover images as early in the morning as possible to reduce dark noise current.
- (DESIRE) Leave rover on until 15:45 LST to collect late afternoon thermal data, perform health check just before shutdown.
- Terminate heating at 15:00
- Disable auto shutdown
- Set Modem Heat to 15 minutes; 10 minutes if following a night-time APXS)
- Set Modem Reheat to 5 minutes.
- Set alarm based wakeup to 08:00 LST
- Perform Read Memory just before last downlink session
- DISABLE RF Wheel Temperature Sensor
- DISABLE Z accelerometer.
- Perform Time Sync just prior to EOD shudown.
- Always command a Level 2 Health Check before shutdown.
- Perform level 2 health check at the end of every traverse command
- Limit image transfer after 1:00 LST (to prevent overheating)
- Limit each "Move Command" distance to 1 meter or less to enable gyro to be recalibrated and thereby reduce the amount of drift.
- Insert longer wait (10 seconds) between APXS cycle start command and APXS turn-off command (turn off devices)
- 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.
- Use Web_Heat_B parameter with Max temp of 30C.
- Future soil mechanics experiments in suspected hard material should have 6 spins of 500 counts rather than 4.
