At the age of 25, not many people can say they are on track to receive a doctorate degree within a year. Fewer can say they are concurrently employed at NASA. And fewer still can say they discovered the evidence of water on Mars. Mary Beth Wilhelm ’12 is a Ph.D. candidate in Geological and Planetary Sciences at Georgia Institute of Technology and a planetary scientist working for NASA’s Ames Research Center in Mountain View, California. In April, she and fellow scientists affiliated with NASA Ames published a paper of their discovery of hydrated salts on Mars, signifying the presence of contemporary water activity on the surface.
