On Mars, massive ice sheets — not rivers — may have carved ancient valleys

[Admin]

Early Mars may not have been quite the warm, wet paradise scientists have hoped for — not if the valleys scarring its surface work the same way as their counterparts here on Earth do.

This is an interesting development. Another report states "Climate modelling predicts that Mars' ancient climate was much cooler during the time of valley network formation,", 'Early Mars was covered in ice sheets, not flowing rivers: study', https://phys.org/news/2020-08-early-mars-ice-sheets-rivers.html

My observation, this model acknowledges the Faint Young Sun problem for early Mars that is why the Mars climate is *much cooler*. Mars would be even colder because of the Faint Young Sun than the Precambrian Earth in the period near 4E+9 years ago when the valleys are said to form, something not commonly reported in reconstructions of Mars past.

This is still welcomed news, because there could be plenty of more so called Ice-sheets on Mars hopefully and can be a easy access to H20 while living on the red planet.
