There is water on Mars!

According to new measurements by Nasa’s Curiosity rover, there is liquid water just below Mars surface.

Scientists had previously thought that conditions on Mars were too cold and arid for liquid water to exist.

Prof Andrew Coates, head of planetary science at the Mullard Space, said:

“The evidence so far is that any water would be in the form of permafrost. It’s the first time we’ve had evidence of liquid water there now.”

The latest findings suggest that soil in Mars is damp with liquid brine, due to the presence of a salt that significantly lowers the freezing point of water. When mixed with calcium perchlorate liquid water can exist down to around -70C, and the salt also soaks up water vapour from the atmosphere.
