water, water everywhere… #curiosity #WaterOnMars

.. But no one to drink it.

The temperature is actually just right. But the lack of an atmosphere on Mars means they water boils ten degrees above the freezing point. However if it could be protected, say by existing below ground, or by adding some chemicals, then water could be abundant on our little brother planet.

New research show that Mars may have ample liquid water just below its surface, according to new measurements by Nasa’s Curiosity rover.

Prof Andrew Coates, head of planetary science at the Mullard Space Mullard Space Science Laboratory, University College London, 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 Martian soil is damp with liquid brine. The presence of a salt significantly lowers the freezing point of water to around -70C, and the salt also soaks up water vapour from the atmosphere.

Plenty of water then, but no one around to drink?
