On Thursday, October 1, 2015 actors Chiwetel Ejiofor and Mackenzie Davis took to the stage with NASA scientists, astronauts, and engineers at the space agency's Kennedy Space Center (KSC) to discuss NASA's journey to Mars with students. The panel took questions from middle and high school students both in the room and across the nation via the internet. The panel was followed by a tour of the launch sites and other facilities at the Space Center. Photos courtesy: Laurel Ann Whitlock
