For the DLR, an atmospheric simulation installation has been set up. Our company also works in collaboration with the German Centre for Aviation and Astronautics in the development of moisture and humidity sensors. The current research projects and developments which seek to investigate the presence of water in the upper Martian soil and in the Mars atmosphere require laboratory-based experimental work around the thermo physical situation. Controlled simulation of Mars conditions is necessary in order to carry out physical, chemical and biological laboratory experiments for the investigation of characteristics and processes with "Mars-analogous" substances. For more detailed information about the work of the DLR and the HUMILAB see the link below.
