Dowsing Mars

New Scientist is reporting that after a year of delays, the Mars Express probe will finally deploy its MARSIS radar antenna. Short for Mars Advanced Radar for Subsurface and Ionosphere Sounding, the instrument consists of three whip-like antennas (two of which are nearly 20 meters long) strung with wire. If successfully deployed, MARSIS should allow the Mars Express probe to search for water as much as a mile and a half below the Martian surface.
