Atmos machines are a type of terraforming equipment that maintains both planetary sized and local atmospheres. An Atmos machine can create artificial sky, as well as heat the environment and thaw the surrounding soil. First used on planets that were too far away from any sun to use solar energy conversion, Atmos machines are now in widespread use throughout the Kodalian Solar System, where the Dyson sphere surrounding the sun Ko has made the use of solar based atmosphere heating impractical.
