[en] Understanding the Martian Magnetosphere-Ionosphere-Thermosphere (M-I-T) coupling is the main objective of the ESA the M-MATISSE mission. Mars Aurora and dust Camera (M-AC) will measure the auroral emission in the nightside at 557.7 nm to measure an important signature of the precipitation of energetic particles into the atmosphere, to reconstruct the role of the magnetic field in driving these precipitations and to identify the profile of their energy deposition. M-AC also measures the disk reflectivity in the dayside to characterize dust spatial distribution and evolution to measure the atmospheric dust, an important driver of Mars' thermosphere state. The periapsis (Henri) observation resolves fine spatial structure (~10 km); while, far-distance (Marguerite) observation and orbital motion increase spatial coverage and therefore frequency of observation of the regions of interest with and without crustal magnetic field. This presentation will detail the design and its performance.
