Early Mars was covered in ice sheets, not flowing rivers - Canadian study

I guess if you are Australian you picture the Martian landscape like outback Australia.

Meanwhile a study by Canadian researchers has come to the conclusion that ancient Mars was covered in ice, resembling much like parts up around the Canadian Arctic Circle.

This research allows us to investigate the advances and retreats of ice sheets at least 35 million years ago - before Antarctica began or earlier - back in time, well before the age of our oldest ice cores.

Bummer!... Elon'd better start packing extra dooners.

These findings completely change the view of ancient Mars - from a warm and humid world, it turns into a cold glacier.

Grau Galofre’s theory also helps explain how the valleys would have formed 3.8 billion years ago on a planet that is farther away from the sun than Earth is, during a time when the sun was less intense.

This has always intrigued about Mars.
How could rivers flow when Mars was colder in the past
than it is now?
