From launching to entering space, astronauts must undergo drastic gravitational changes like acceleration, loss of weight, etc. In space, they also face the sense of disorientation. Therefore, a gyro chair is used to train astronauts to overcome and adapt to these situations. The gyro chair rotates in three axes that are respectively tilting, horizontal and unaligned, using rotation in different speed and directions to simulate the environment of space where the sense of direction is lost.
