The primary scientific objective of the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS), which will be on board Mars Express mission scheduled for launch in 2003, is to map the distribution and depth of the liquid water/ice interface in the upper kilometres of the crust of Mars. MARSIS will also provide unique information to help us understand the recent crustal evolution of the planet. In addition an ionosphere sounding experiment will measure the electron density and structure of the upper atmosphere during day-time operations.
