Just because the movie’s in heavy rotation on HBO right now doesn’t mean you should skip this free screening at Sarratt. First, The Martian was made for the big screen, where you can see the sweeping Martian landscape that Matt Damon is battling to survive and hear Bowie’s “Starman” as the Hermes rides to the rescue. Second, after the screening a team of actual scientists (Tracie Prater, Ph.D. 2012 (Mechanical Engineering), aerospace engineer at NASA Marshall Space Flight Center; David Weintraub, professor of astronomy; and Rick Chappell, research professor of physics) will discuss the science of the movie. (Spoiler alert: They got a lot of stuff right in the film and in the book it’s based upon.) STEVE CAVENDISH
