FASTER… WHOA! Elon Musk unveils radical ‘megashuttle’ that will take man to Mars in 80 days to set up a million person city.

‘What I want to achieve is make Mars seem possible, to show that we can do it in our lifetimes, and you could go,’ he said at the International Astronautical Congress in Mexico.

However, he warned the trip was likely to be dangerous – and said candidates for the first missions ‘must be prepared to die’.

Musk outlined plans for a fleet of large ‘megashuttles’ that would take 100 people at a time to Mars for $200,000 a trip, after warning ‘eventually history suggest there will be some extinction event on Earth’.

They’ll all be strangers in a strange land — and how will humans change, physically, on a planet with a surface gravity just one-third of the Earth’s?
