Did Phoenix spot liquid water on Mars?

摘要

Stunning news comes from Mars as the Phoenix Mars Lander may have touched and captured the first evidence of liquid water on the red planet - droplets that apparently splashed onto the spacecraft's landing gear at touch-down (see Spaceflight, October 2008, p376), writes Rudolf van Beest.rnPhoenix had earlier found hard-frozen water ice, but of much more importance was its finding of salty brine-like water at its Arctic landing site, where temperatures never rose above -20 degrees Celsius during the time Phoenix was active.
