Minerals, Microbes, and Mars

Location: Geology 3656
Time: 2:30PM

Celestian collaborates with JPL scientists in a search for signs of ancient life preserved in minerals on Earth. Using non-destructive analytical methods, they measure biosignatures (like beta-carotene) in crystals that are thousands or even millions of years old. Their findings will help assess data from NASA missions to Mars and the icy moons of Saturn and Jupiter, places that may harbor life.
