The Christa McAuliffe Center will host a panel discussion, Space Exploration and Human Evolution, at 4:30PM on April 8 at Framingham State University’s McCarthy Forum.  An astronaut, a physicist, a writer, and an environmental advocate will discuss questions such as:  Is the solar system ours for the taking?  Does living in zero gravity affect the way we think?  What is the likely political evolution of a human settlement on Mars?  Can we avoid the mistakes made in the earlier periods of the exploration of the Earth?
