Adaptation Processes

Preparation for extended travel by astronauts within the Solar System, including a possible manned mission to Mars, requires more complete understanding of adaptation to altered inertial environments. Improved understanding is needed to support development and evaluation of interventions to facilitate adaptations during transitions between those environments. Travel to another planet escalates the adaptive challenge because astronauts will experience prolonged exposure to microgravity before encountering a novel gravitational environment. This challenge would have to be met without ground support at the landing site. Evaluation of current adaptive status as well as intervention efficacy can be performed using perceptual, eye movement and postural measures. Due to discrepancies of adaptation magnitude and time-course among these measures, complete understanding of adaptation processes, as well as intervention evaluation, requires examination of all three. Previous research and theory that provide models for comprehending adaptation to altered inertial environments are briefly examined. Reports from astronauts of selected pre- in- and postflight self-motion illusions are described. The currently controversial tilt-translation reinterpretation hypothesis is reviewed and possible resolutions to the controversy are proposed. Finally, based on apparent gaps in our current knowledge, further research is proposed to achieve a more complete understanding of adaptation as well as to develop effective counter-measures.

<p><strong>Abstract.</strong> The purpose of this mapping project was to create a cartographically accurate representation of an Exploration Zone at the Eastern Valles Marineris outflow region within equatorial Mars. There are numerous problems associated with mapping planetary surfaces. Data and imagery for Exploration Zones at a spatial and spectral resolution sufficient for human landing site evaluation and traverse planning have not been acquired yet. Additionally, as technology evolves, it is very difficult to extrapolate which mapping technologies will be used in the near and far future. In order to create this map, assumptions about the future of mapping had to be made, publicly released data for the area of interest had to be sourced, and data analysis had to be performed. One of the key elements of a successful mission is how to communicate the geospatial aspects of the mission planning process to the general public. The results show that using existing data and traditional static cartographic methods, even extra-terrestrial geographic discoveries can be made and disseminated to the public in an attractive and easily understood format.</p>
