Is there water deep within Mars’s crust? In this video, we dive into the story of how scientists discovered that there may be water 6 to 12 miles below the surface of Mars. This water would exist in the cracks and pores of rocks, and if brought to the surface, it would cover Mars in a mile-deep ocean. Additionally, microscopic life has been found up to 3 miles deep into Earth’s crust, meaning it’s possible that some form of life survives in these pockets of water on Mars. What do you think of this amazing discovery?
