There is in-fact liquid water on the red planet Mars.
Of you've been keeping up on Mars news, I'm sure you are already aware of the discovery of ice, snow and even ancient riverbeds... Liquid water is a whole new ball park. To be fair, the rover did not find a flowing river or a lake, but instead water molecules bound to minerals in the Martian soil.
Researchers say that every cubic foot of Martian soil contains about two pints of liquid water. All things told, about two percent of the Martian soil is made of up water.How exactly did Curiosity make the discovery...?? Laurie Leshin, dean of science at the Rensselaer Polytechnic Institute explains:
Curiosity picked up and sieved a scoop of soil from the surface before dropping it into an on-board oven. "We heat [the soil] up to 835C and drive off all the volatiles and measure them," she said. "We have a very sensitive way to sniff those and we can detect the water and other things that are released."
