Impossible Space #312

April 10, 2015

This week we're exploring the limits of science exploration in both fictional and fact. We're joined by "lifelong space nerd" Andy Weir, to talk about his debut novel "The Martian," that pits human inventiveness and ingenuity against the unforgiving environment of the red planet. And astrophysicist and science blogger Ethan Siegel returns to explore so-called "impossible space engines," and what news stories about them can teach us about journalism and science literacy.
