PRESS RELEASE
On its first day on Mars, the Sojourner microrover is scheduled to perform several critical activities. The rover will be powered on early in the morning for the first time, awakened either by the rising sun shining on its SOLar panel, or by command from the lander. It will then receive its first set of commands, which will put the rover into the appropriate configuration for on-Mars activities. Sojourner will then operate its onboard Alpha Proton X-ray Spectrometer (APXS) for three hours in order to calibrate the instrument. Following this activity, the rover will perform the first Material Adherence Experiment, or MAE. The next command sequence from the lander will order the rover to retract the APXS to a safe position before the lander releases its rover egress ramps. During these morning activities, the Earth-based rover team will assess whether the forward or rear (or both) ramps are safe to deploy. After the appropriate ramps have been released, a third sequence will cause the rover to standup, rising from its stowed position to its full height and maximum ground clearance. After another MAE experiment, the rover will await the final command sequence of the first day, which will command it to drive down one of the two ramps onto the Martian surface.
Summary of Planned Rover Activities for the morning of Sol 1:
| PDT | MLST | Rover Acivity |
|---|---|---|
| 13:51 | 06:49 | Rover wakes up on Mars for the first time |
| 14:21 | 07:21 | Begin APXS calibration data collection |
| 17:08 | 10:03 | End APXS calibration data collection |
| 17:30 | 10:21 | Perform MAE experiment |
| 17:56 | 10:47 | Retract APXS before ramp release |
| 18:15 | 11:06 | Rover standup |
| 19:10 | 11:59 | Perform MAE experiment |
