Featured I Update on liquid water on Mars - maybe it is sand?

    NASA announced in 2015 that they found some evidence for the existence of liquid water on Mars today - at least temporarily and underground.

    A new study comes to a different conclusion and proposes sand as origin of the observed material transport downhill.

    As interesting as these features are, the rovers on the ground stay away from them - exactly because they are interesting. The rovers are not completely sterile, so NASA avoids going close to places where there is a remote chance that life could survive.

    Does that question that significant amount of frozen water can be found? (Possibly used by a small greenhouse experiment?)

    This is unrelated to the ice that has been found independently.

    Here is a Science magazine news article interviewing one of the guys who did this research.
    Lots in statements about lots of interesting subjects: RSL, water on Mars, where to look for life, ...

    Tardigrades could make the crossing and survive. It would be interesting to see how well they mobilized and reproduced (if at all) under the extreme conditions of Mars; not to mention what would they eat.
