In the framework of the Mars exploration with new generation of lander and rover, IAS will propose CIVA/Mars, an ultra-miniaturised IR spectral imaging analyser dedicated to the in-situ mineralogical characterisation at microscopic scale of Martian samples. The instrument profits by the inheritance of CIVA/Rosetta developed at IAS for the ROSETTA lander which will visit the comet Wirtanen. I have started the adaptation of this system to the specific Mars environment. The major technical change is linked to the presence of the Martian atmosphere which leads to the absolute need of the same vacuum tight package but externally cooled below 155 K, in order to avoid any condensation on it ; the extra cooling of the detector itself down to 120 - 140 K being done by means of an active thermo-electrical cooler (TEC) instead of a purely radiative process. I defined the optimised TEC, performed the space qualification and will calibrate the instrument in 2002-2003
