SummaryThe moon surface and sub-surface scattering mechanism and the associated parametric space of inversions make challenging the detection of potential ice inclusions on the lunar poles soil. However the Clementine bistatic radar experiment was able to find evidence of ice in the Shackleton area[1]. Then for a easier study of ice mapping and typology, a 2 years experiment (2009- 2010) was made to prepare future human EVAs and robotic follow-up on the moon. This project named, NASA Moon and Mars Analog Mission Activities (MMAMA), had been performed on the earth, on the Haughton meteorite impact crater on Devon Island, Canada where tools like Lidar, GPR or XRF has been used. A larger-scale map with also a precise characterization of the ice would be necessary to complete this first experiment. Thus, Alos- palsar L-band acquired a scene this july 2010 but a smaller nominal spatial resolution, fewer than 5 meters is required to detect small glacial shapes like some hydrolaccoliths (pingos). The first objective would be to make a classification with a textural analysis of the Haughton crater North West area using high resolution dual-polarimetric SAR images. The second objective would be to extend the previous characterization made with XRF, Lidar and GPR to this 20x20km area with this classification. Only 4 images per satellite would be necessary for this study. Or, forboth missions, 1 ascending and 1 descending scene in winter (betweenOctober 2010 and April 2011) and in summer (july 2011-august2011). The results would follow the MMAMA project and its publications. Beside, this experiment would be funded by the NASA MMAMA project, up to 50.000 dollars per year for 3 years (2010-2013).
