Horton Newsom is currently working on impact crater processes on the Earth and Mars. In the last few years, he has visited impact craters in the Arctic, in Africa and India. He is a science team member for the ChemCam Laser Induced Breakdown Spectroscopy experiment on the next Mars Rover mission, the Mars Science Laboratory "Curiosity," scheduled to launch in 2011. Says Horton, "I continue to work with many former LPL students, and enjoy working with my current students and post docs."
