Spiral troughs in Mars polar caps are born in ‘cyclic steps’
Both Martian polar caps have deep spiral troughs that slice into them for dozens or hundreds of kilometers, but their origin and development has been much debated by scientists. New work by a team of researchers led by Isaac Smith … Continue reading

No flow found in north polar ice layers
The northern polar ice cap of Mars contains a thick stack of layers rich in water ice. Under the right conditions ice can flow, as seen in ice sheets and glaciers on Earth. What about Mars? A group of scientists … Continue reading
Polar gullies erode from carbon dioxide flows
Gullies on Martian slopes form by flowing water, most probably trickles of snowmelt or groundwater. But what about the gullies found in places such as the high latitudes and polar regions where temperatures never rise above the freezing point for … Continue reading
