British physicist Stephen Hawking has repeatedly warned us that we have just a century or two to move off Earth, and he just shared his vision for how to do it.
Hawking laid out a timetable this week during a lecture titled “The Future of Humanity,” presented to an audience of 3,000 attending the Starmus Festival in Trondheim, Norway.
He said a base could be established on the moon within 30 years to serve as a gateway to the rest of the solar system. Settlers could follow up with a Mars base within 50 years. But Hawking went on to call for setting an even speedier schedule for space exploration.
The 75-year-old, wheelchair-riding physicist recalled President John F. Kennedy’s vision of putting Americans on the moon by the end of the 1960s – a deadline that was met with the Apollo 11 mission in 1969.
“A goal of a base on the moon by 2020, and a manned landing on Mars by 2025 would reignite the space program and give it a sense of purpose in the same way that President Kennedy’s target did in the ’60s,” he said, using his computer-generated voice. “The spin-off to this would be an increase in the public recognition of science generally.”
