Active Response Gravity Offload System
NASA has used two systems to train astronauts for weightlessness. The first is the Reduced Gravity Simulator that suspended the astronaut at an angle of 80.5 so that only 1/6th of his or her weight was supported by the ground, while the rest was supported by a pulley system. The other system, designed during...
