About This Episode
To answer your questions about the movie Gravity, Neil deGrasse Tyson and Chuck Nice get a little help from 2-time Space Shuttle astronaut Mike Massimino. They explore the scientific inaccuracies in the movie – and how much Gravity got right. Mike gives it 2 thumbs up for the look and feel of being in space, from the spacesuits to the tools he actually used. He discusses how actual NASA astronauts train for emergencies, the time he tore his glove fixing the Hubble telescope, and the real rescue plans for his flights. @Astro_Mike (he was the first human to Tweet from space!) also describes impact of weightlessness on your inner ear and sense of balance, and how your brain adapts after a few days of zero-g. Neil explains why you’re weightless in space in the first place – it’s free fall, not lack of gravity – and describes an experiment you can do at home to prove it and amaze your friends and family.
