"Britain's Astronomer Royal Advocates Sending Robots, Not Humans, into Space"

Britain's Astronomer Royal Martin Rees believes that sending humans into space is a waste of public money, as robots can now perform tasks that previously required human presence. He advocates for space exploration to be left to billionaires and those willing to pay for trips themselves, emphasizing that it should only be for those prepared to accept a high level of risk and be privately funded. Rees also expressed skepticism about Elon Musk's ambition to colonize Mars but praised his achievements in rocket and electric car technology.
