PARIS, FR - Buzz Aldrin, the second man to walk on the moon, in discussing the differences in his trip to the moon and back, said that going to Mars is a very different prospect.
It took Aldrin, Neil Armstrong and Michael Collins eight days to go to the Moon -- 380,000 kilometres (238,000 miles) from Earth -- and return in July 1969, aboard Apollo 11.
The distance between the Red Planet and Earth varies between 55 million (34 million miles) and more than 400 million kms (250 million miles).
Even at the most favourable planetary conjunction, this means a round trip to Mars would take around a year and a half.
"That's why you [should] send people there permanently," said Aldrin. "If we are not willing to do that, then I don't think we should just go once and have the expense of doing that and then stop."
