| The Mars Environmental Dynamics Analyzer (MEDA) is a suit e of sensors that will operate on the NASA Mars 2020 Rover. Two of the sensors are the Air Temperature Sensor (ATS) and the Thermal InfraRed Sensor (TIRS).The main aim of ATS is to measure the atmosphere temperature. It consists of five units located in different parts of the rover, each including three chromel-constantan thermocouples. The thermocouples? wires are subjected to free and natural convection, Sun illumination and receive infrared radiation from the planet?s surface. The prediction of accurate temperatures of the wires is crucial for the verification of the correct performance of the sensor.The main goal of TIRS is to measure the radiative flux emitted by the planet surface, the sky and the surrounding CO2 atmosphere. It consists of a set of five sensors, assembled in a common case, working in four wavelength bands. TIRS has a quite strict thermal requireme nt in terms of thermal gradients in the sensors, which cannot exceed 24 mK. TIRS will be located in the Remote Sensing Mast (RSM) of the Mars 2020 Rover. | |
