Astronaut and Aquanaut Performance and Adjustment Behavioral Issues in Analagous Environments

The utility of analog environments as sources of data for future, long duration space missions is discussed. The undersea habitat is evaluated on a point by point basis for similarities and differences with Space Station and a possible Lunar Base. The comparability of Antarctic wintering-over stations is also considered. Critical issues for research are described as well as the requirement that participants be involved in the conduct of meaningful work.
