Between 2012 and 2015, MARSIS scanned an area called the Planum Australe on the southern ice cap of Mars.
The paper, authored by the Italian MARSIS team, outlines how a "bright spot" was detected in radar signals about 1 mile (about 1.5 kilometers) below the surface of the ice cap in the Planum Australe region.
The team used a radar sensor on Mars Express, an orbiting probe, to survey a 200km-wide area of Planum Australe, the planet’s southern polar plain.
