In 2001, a frozen ocean was discovered beneath the surface of Mars.

Russian scientists and NASA have studied ice core samples from the Antarctic - the closest place on Earth to conditions on Mars.

Microbes frozen in the Antarctic permafrost for millions of years came back to life when warmed in a lab.

Scientists speculate that Mars' molten core may be hot enough to melt the ice and produce liquid lakes.
