Though we consider Mars as a dry and dusty wasteland, it as soon as contained monumental quantities of water on its floor.
Newly launched pictures from the European Area Company (ESA) present extra proof of the Crimson Planet’s earlier incarnations — which included water on what was a hotter planet round three.5 billion years in the past.
The photographs, taken by the ESA’s Mars Categorical satellite tv for pc, present an historic area within the southern highlands of Mars crammed with craters which have markers of flowing water. The area company says the area’s topography means that water flowed downhill from north to south, carving out valleys as much as 1.2 miles throughout and 656 ft deep because it did so.
“We see Mars as a chilly, dry world, however loads of proof means that this was not at all times the case. Analysis in previous years as a substitute more and more signifies that the planet as soon as had a thicker, denser ambiance that was capable of lock in far better quantities of heat, and due to this fact facilitate and assist the move of liquid water on the floor beneath,” the ESA mentioned in a press release.

It is nonetheless unclear, in line with scientists, the place the water on the Crimson Planet got here from. The chances embody groundwater, precipitation and even melting glaciers.
A query that follows naturally from the dialogue of water is, May Mars have been appropriate for all times types?
Seeking a solution, subsequent 12 months ESA and Roscosmos will launch the ExoMars mission comprising a rover – just lately named Rosalind Franklin – and a floor science platform. The rover will drive across the planet and drill beneath the floor in the hunt for indicators of life.
