Tjalling de Haas: Debris flows on Mars

Traces of recent water on the red planet

Since the first telescopes we earthlings have been fascinated by our neighbouring red planet. Deep river valleys, vast deltas and traces of debris flows, suggest a wet past on Mars. After many wild theories of mainly astronomers on the occurrence of water and life on Mars, geoscientists decided to get involved. And they came to very different conclusions. The planet seems to have been very dry over the last millions of years. But Tjalling de Haas suggests that the traces of recent debris flows indicate there still should be fluid water on the surface of Mars once in a while.
