INVERSE - Timothy Lyons, a distinguished professor of biogeochemistry, discusses his new research to better understand the history of the atmosphere on Mars.
Scientists have developed a new model to better understand whether Mars once hosted water — and maybe even life.
The Martian surface is an inhospitable place: It is too cold for humans to live comfortably on it, and it lacks liquid water. But it was not always so. Some 4 billion years ago, the Red Planet was a very different place. It may even have hosted oceans. So what happened to make Mars lose its water, and, in turn, potentially its surface life?
