“Dirt sample reveals two pints of liquid water per cubic feet, not freely accessible but bound to other minerals in the soil”
Water has been discovered in the fine-grained soil on the surface of Mars, which could be a useful resource for future human missions to the red planet, according to measurements made by Nasa’s Curiosity rover.
Each cubic foot of Martian soil contains around two pints of liquid water, though the molecules are not freely accessible, but rather bound to other minerals in the soil.
“We tend to think of Mars as this dry place – to find water fairly easy to get out of the soil at the surface was exciting to me,” said Laurie Leshin, the lead author on the Science paper which confirmed the existence of water in the soil and the dean of science at Rensselaer Polytechnic Institute. “If you took about a cubic foot of the dirt and heated it up, you’d get a couple of pints of water out of that – a couple of water bottles’ worth that you would take to the gym.”
