Underspace Trainer Work -

An Underspace Trainer is a large, swimming pool-like facility that simulates the microgravity environment of space. The trainer consists of a long, narrow pool filled with water, which provides a buoyant environment for astronauts to train in. The pool is typically equipped with a suspended system of bars, handles, and other equipment that allows astronauts to practice spacewalks, emergency procedures, and other critical skills.
