Buzz Aldrin: Mars Pioneers Should Stay There

From Cosmos:

PARIS: The first astronauts sent to Mars should be prepared to spend the rest of their lives there, in the same way that European pioneers headed to America knowing they wouldn't return home, says moonwalker Buzz Aldrin.

In an interview with reporters, the second man to set foot on the Moon said the Red Planet offered far greater potential than Earth's satellite as a place for habitation.

No coming back

With what appears to be vast reserves of frozen water, Mars "is nearer terrestrial conditions, much better than the Moon and any other place," Aldrin, 78, said in a visit to Paris last week. "It is easier to subsist, to provide the support needed for people there than on the Moon."

It took Aldrin, Neil Armstrong and Michael Collins eight days to go to the Moon – 380,000 km from Earth – and return in July 1969, aboard Apollo 11.

Going to Mars, though, is a different prospect. The distance between the Red Planet and Earth varies between 55 million km and more than 400 million km. 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."
