As protagonist Ryland Grace fights to save Earth - and possibly the universe - in Project Hail Mary, author Andy Weir discusses the science behind his sci-fi story and what it’s like to see it adapted for the big screen. From a diversity of aliens thriving in extreme environments, to our sun’s shortening lifespan, to the conundrum of keeping astronauts alive during intergalactic missions, we consider the possibility of science fiction becoming future reality. A NASA astrobiologist who consulted on the book weighs in on how Earthly creatures have inspired some of our favorite science fiction aliens. Plus, science fiction author Becky Chambers discusses how she balances science fact with fiction in her work.
