SchrodingerZ writes: Planetary Geologist Ellen Stofan, expert in the terrains of Venus, Mars, and Titan, has recently been appointed the Chief Scientist for the space agency. Stofan will act as the top adviser for Charles Bolden, NASA's current administer. Beginning August 25th, Stofan will be Bolden's head adviser for NASA's project planning and investments. She will replace former chief scientist Dr. Waleed Abdalati, who left his position to be the director of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado. Stofan has both a masters and doctoral degree of geological sciences from Brown University, and is known for her involvement in the Applied Science Laboratory's project to put a boat on Saturn's moon Titan, as well as a member of the radar team for the Cassini spacecraft . Though joining in a time of large budget cuts, Bolden explains, that '[Stofan's] breadth of experience and familiarity with the agency will allow her to hit the ground running. We're fortunate to have her on our team.'
