, Future field test on Martian analogues are planned to investigate the synergy between Ma_MISS and WISDOM. For more than ten years the MARSIS (Orosei et al., 2015) and SHARAD (Seu et al., 2007) radar sounders have been investigating the Martian subsurface. They operate at low frequency (2-20 MHz) from the Mars Express and the Mars Global Surveyor and orbiter, respectively. They have revealed subsurface structures in the polar regions, ) as well as in the equatorial regions, 2008.
