Sending astronauts into space is arguably one of society’s most impressive scientific achievements. It’s a marvel of engineering, and it also taps into the human desire for exploration.
But just because we can send humans into space, should we? Robots are already good space explorers. And they’re only going to get smarter in the near future.
Martin Rees, the United Kingdom’s Astronomer Royal, and Donald Goldsmith, astrophysicist and science writer, argue that the cost of human space travel largely outweighs its benefits. They talk with Ira about their new book, The End of Astronauts: Why Robots Are the Future of Exploration.
