Space simulation refers to the use of computer models and virtual environments to replicate the conditions of outer space. This technology allows scientists and engineers to study various aspects of space exploration, such as spacecraft design, orbital mechanics, and the effects of microgravity on human physiology. These simulations can also be used for training astronauts, helping them prepare for missions by practicing maneuvers and problem-solving in a controlled setting. By mimicking the challenges of space travel, such as those faced by NASA or SpaceX, space simulations play a crucial role in advancing our understanding of the universe.
