Radar evidence of subglacial liquid water on Mars
Liquid water under Mars' southern ice cap Mars is known to host large quantities of water in solid or gaseous form, and surface rocks show clear evidence that there was liquid water on the planet in the distant past. Whether any liquid water remains on Mars today has long been debated. Orosei e...

Liquid water under Mars' southern ice cap Mars is known to host large quantities of water in solid or gaseous form, and surface rocks show clear evidence that there was liquid water on the planet in the distant past.
