The atmospheric simulation installation and the HUMILAB laboratory originated from the cooperation of our company with the German Aerospace Center (DLR), Berlin. The laboratory offers the possibility to simulate different atmospheric states. The parameters of temperature, gas composition and humidity in this gas mixing system and programme are regulated to be specifically coordinated to the conditions on Mars. In addition, optical radiation and pressure can be generated and regulated. Mainly biological experiments and sensor tests are carried out at DLR Laboratory.
