What lies beneath

(PresseBox) (Paris, )
There is much more to Mars than meets the eye. By using the radar on Mars Express, we can see several kilometres below the surface to see what lies beneath.

The radar creates subsurface images of Mars by beaming low-frequency radio waves towards the planet, which are reflected from any surface they encounter.

While most are reflected by the planet's surface, some travel deeper and bounce off interfaces between layers of different material, such as between rock, water or ice.

The strength and timing of the radar echoes that arrive back at Mars Express are a gauge of the depths oo cjvihkogq xbeft zu tetuwpukdvd qfqusslupi.
