"Getting Humans To Mars Could Happen By 2030s" - Former NASA Deputy Administrator

Are we alone in the universe? Can humans travel to far-flung planets? Are there other habitable planets? These are big questions, but there are scientists out there working to solve them, and in the process take a deeper look at our own Earth. One of those people is Dava Newman, the Apollo Program Professor of Astronautics at MIT and a former NASA Deputy Administrator. She will give a public lecture at UW as a visiting scholar. She sat down with Wyoming Public Radio's Caroline Ballard to discuss her work and the possibility humans will go to Mars.
