FNP project TEAM 2011/7-9Mars: Another Planet to Approach Geoscience Issues

Wroona is a small blue world in Wroona system, located on the far edge of the Inner Rim in the Rayter Sector. The planet's continents are separated by vast oceans, and their blue-sand beaches stretch for thousands of kilometers. The near-human inhabitants of Wroona, numbering over seven billion, are a blue-skinned species with a lighthearted and optimistic outlook on life. StarWars wiki

What controls flow propagation?Why is basal friction so small (<10°)

• Water ?• Processes at bedrock/debris flow interface

o erosion?o auto-fluidization?

What is the landslide trigger?

Postglacial slope destabilization (sackung),

a dangerous, underevaluated processof landslide genesis in terrestrial mountains!

We do have specialists of the glacial and periglacial conditions prevailing on Mars, that control landscape evolution.

Biological activity plays a key role in rock alteration on Earth. Will this work reveal a method for identification of biological activity on Mars ?
