The End of Astronauts: Why Robots Are the Future of Exploration
In The End of Astronauts: Why Robots Are the Future of Exploration, they challenge the three most commonly cited rationales for putting humans in space ... As scientists, the authors don’t have much patience for arguments based on vague impulses.
