“The public’s infatuation with finding life on Mars stems from the many characteristics both Earth and Mars share,” said study co-author Dr. Brendan Dyck, from the Simon Fraser University in Canada and the University of Cambridge in the UK.
“Early on, both planets had similar potential to sustain life, but as time evolved, Mars lost its surface water along with its potential to sustain complex multicellular life.”

In the study, Dr. Dyck and colleagues calculated the volume of water that could be held in the minerals that make up the Martian...
