# C.A.D

Informational Guide on the Duskwork's C.A.D and trivia on previous usage from the Ad Astra Landings.

*One of the most important buildings that help in the sustainability of any colony on Mars, much like the greenhouses, the C.A.D. It is also sometimes known as the very wordy Cryo Atmosphere Distiller. The cryogenic distillation process specializes in capturing Carbon Dioxide from the Martian atmosphere by pulling in air from an air intake and compressing the air then further cooling and distilling it down for transportation.
