Experiment Freespace
In a conventional micro-gravity experiment, experimental equipment is fastened to a standard rack and the procedures are carried out by an experimenter seated in a chair. When an experiment is conducted in a free area, the experimenter or subject can perform the micro-gravity experiment in any number of relaxed positions or postures in a safe space with cushioned floors and walls. Manned flight training can be carried out in standing, recumbent, or sitting positions while measuring biosignals, conducting free-floating experiments, and so on.
