TL;DR: In this article, the authors simulated conditions of the unprotected Martian surface (i.e. 6344kJm−2) and protected niche conditions (269kJ m−2), and found that the entire lichen not only survived and remained photosynthetically active, but also adapted physiologically by increasing its photosynthetic activity over 34 days.

TL;DR: In this article, a parallel plate capacitor has been developed to obtain isothermal dielectric spectra of fine-grained soils in the frequency range from 10 Hz to 1.1 MHz at Martian-like temperatures down to −70 °C.

TL;DR: Capacitive humidity sensors (Sensirion SHT75) were tested at the German Aerospace Center (DLR) in its Martian Simulation Facility (MSF) and showed a strong cross-sensitivity of the sensors to CO2 and, compared with air, a strong pressure sensitivity as well.

TL;DR: The Mars Simulation Facility (MSF) as mentioned in this paper has been designed to simulate Martian environmental conditions in terms of pressure (1,060 hPa), temperature (−70 to +130 °C), humidity (−46 °C frost point (FP) to −101 °C FP at 7 hPa, light (150 W Xenon lamp emitting in the range of 250 −2,190 nm with calibrated intensity), and gas composition (up to five constituents).
