Mars Desert Research Station, Mission Summary (Crew 22) Mars Society

The biggest constraints to working in Sim were decreased visibility and communication, both of which made teamwork more difficult. In Sim we communicated rarely and mainly used gestures. It was also difficult to see our work, especially when the Sun was low, or to be aware of what others were doing. The weight of the backpack and the bulk of the suit had a smaller effect than the decrease in visibility and communication.
