Estimated Time: 1 hour, 1-4 people
An MMSEV has become stuck at a science location 18KM from the habitat. The mission is to rescue them using the second MMSEV during a worsening dust storm to simulate navigation in the dusty Mars environment. Then, options exist for how to effect a rescue:
1. Transfer all crew to the working MMSEV and drive back - fastest return time, but leaves the disabled MMSEV behind
2. Attempt a fix of the MMSEV wheel and dig it out of the regolith - takes time, but a faster drive back and recovers the second MMSEV
3. Tow the MMSEV back - slowest drive back option, but fastest recovery time
How much the dust storm affects driving and navigation. The idea is for the storm to get progressively worse so that the drive time in good and bad visibility is directly comparable by looking at the time taken to drive between waypoints.
The second key concept is decision making on time critical tasks. Oxygen is limited, so do you bring the two EVA crew back and abandon the stuck MMSEV, or do you mount a 4 person EVA to attempt a fix and recover the vehicle? Do you spend the time making it drive-able and return both MMSEV quickly, or do you tow it back more slowly? This is against the backdrop of a worsening dust storm. Any metrics need to balance mission safety. Returning 4 crew in 1 MMSEV fast is the easy option, but this is designed to provide useful experience of operating in low visibility, which is something that XR is ideally suited for.
