What Science Fiction Gets Wrong About Space Travel

Geoff Brumfiel, NPR science correspondent, sheds light on the engineering hurdles of space travel that often get glossed over in science fiction tales. He discusses the stark contrast between cinematic portrayals, like those in Iron Man and Star Wars, and the real-world challenges of propulsion. With insights into thrust and fuel efficiency, Geoff explores innovative technologies, from ion engines to nuclear power, and emphasizes the need for new engineering solutions to make human missions to Mars a reality.
