About Space Simulation: The conditions felt in space are extreme. Satellites, CubeSats, and spacecraft experience constant high vacuum and large temperatures swings during the day-night cycle as they pass into the suns unfiltered rays and then into the earth’s cold shadow. For example, an object in low earth orbit without temperature regulation mechanisms may reach -170 °C in the night and 123 °C in the day. Due to the high cost of launching an object into space, it is crucial, and often mandatory, to rigorously test all individual components and the entire assembled device before deployment.
