“On Mars you can start a self-sustaining civilisation and grow it into
something really big.”
The 146-year-old Royal Aeronautical Society last November awarded Mr Musk, who
founded his third company SpaceX in 2002, a gold medal for his contribution
to space exploration.
The California-based engineer has previously talked about sending the Mass
Cargo Transport rocket powered by liquid oxygen and methane, to Mars –
carrying volunteers for about £300,000 a person.
One of America’s most respected private space entrepreneurs, Mr Musk – worth
about £1.25bn – has admitted the challenges remain daunting.
These include the dangers of deep-space radiation, bone-rot and toxic dust.
He recommends the size of the new society should be around 80,000 people. “Too
few, and the gene and culture pool dries up,” he said. “Too many and you
risk civil war.”
