The Evolution of Life on Mars
The conditions on Mars about four and a half billion years ago strongly resembled those on the Earth when life evolved here. Conditions after about 800 million years on Mars turned pretty harsh. So to me, chances are life went extinct and it didn't get very exciting before it went extinct. This isn't like an exciting type of fossil for most people, but for a geologist, it means everything.
This week’s Pathfinder podcast features Dr. Ellen Stofan, the Under Secretary of Science and Research at the Smithsonian. She oversees its science research centers and the National Air and Space Museum, National Museum of Natural History and the National Zoo.
Dr. Ellen Stofan is an American geologist and former NASA scientist who specialized in the geology of Venus, Mars, and Saturn's moon Titan. Ellen has held several key positions at NASA, including Chief Scientist from 2013 to 2016. During her tenure as Chief Scientist, she was instrumental in the development of a long-term plan to get humans to Mars and worked on strategies for NASA's science programs and science-related strategic goals and objectives.
Ellen is now the Under Secretary for Science and Research at the Smithsonian. She oversees its science research centers and the National Air and Space Museum, National Museum of Natural History and the National Zoo.
