Mechanical Engineer Armen Toorian explains that the wheel tracks of the Mars rover Curiosity are used to determine how far the rover has travelled on the red planet. Lead Curiosity Driver Matt Heverly and Research Scientist Bethany Ehlmann elaborate on the unusual working conditions involved with a Mars rover expedition. Research Scientist Bethany Ehlmann and Mechanical Designer Scott McGinley explain some of the scientific instruments aboard the Mars rover Curiosity. Engineers at the Jet Propulsion Laboratory (JPL) explain how they simulate martian conditions and conduct tests with model rovers to prepare the Curiosity rover for its journey to Mars and its work on the red planet. A glimpse of the full-scale model of the Mars rover, Curiosity. On display at the Exploratorium from August 1st to September 16, 2012. This model is on loan from JPL, NASA's Jet Propulsion Laboratory, and there are only two on loan in the United States! Geneticist Mark Stoneking discusses a special type of genetic material called mitochondrial DNA gets passed directly from mother to child. Largely unchanged from generation to generation, this genetic material gives researchers a way to track populations back in time. Dr. Stephen H. Schneider joins us to discuss climate change. Dr. Schneider was honored in 1992 with a MacArthur Fellowship for his ability to integrate and interpret the results of global climate research through public lectures, seminars, classroom teaching, and research collaboration with colleagues.
