Sensors draw Mars duty
The Finnish Meteorological Institute’s MEDA PS and MEDA HS sensors are set to measure the pressure and humidity of the atmosphere of Mars. Based on Vaisala’s Barocap and Humicap sensor technologies, FMI’s devices will be part of the Spanish Mars Environmental Dynamic Analyzer (MEDA) suite of environmental sensors, which will be installed in the Mars 2020 Rover.
MEDA PS and MEDA HS are designed, built, and calibrated by FMI. Pressure measurement devices were finalized earlier this year and the humidity measuring instruments are now complete and ready for final testing.
