Underground Lake Found On Mars Beneath A Mile of Ice

This is the south polar cap of Mars as it appeared to the Mars Orbiter Camera on the Mars Global Surveyor on April 17, 2000. An underground lake was found near here.

Scientists say they’ve found what appears to be a briny underground lake near the south pole on Mars a mile below the surface. It possible that some kind of microbial life once lived in the lake.
