PSEUDO SPACE EXPERIENCE SYSTEM

PROBLEM TO BE SOLVED: To provide a water tank that has an image displaying function, and a buoyancy adjuster that a person who is having experience wears, in a system for easy pseudo space experience on the ground designed to solve the disadvantages that a conventional planetarium can not provide gravity-free or low-gravity experience and that an in-water-tank training system held by a space development institution has no image displaying function and can not provide experience of realistic sensation of a space walk, and to facilitate pseudo space experience with realistic sensation on the ground. SOLUTION: The pseudo space experience system comprises the water tank including a spheric wall and a planar floor both of transparent acrylic resin, water stored in the interior, a water purifying system, a platform of transparent acrylic resin, on which a visitor who is having experience rides, and a piston for moving the platform vertically into the water tank; a screen for displaying an image; and the buoyancy adjuster having a buoyancy adjusting function.
