Want to learn how to survive on Mars? Look to Antarctica.

One is blinding white and the other a dull, dusty red. But both are cold, barren worlds, difficult to reach and full of tantalizing scientific mysteries.

And lessons from the first world, Antarctica, may be vital for those who want to be the first humans on the second, Mars, according to Stan Love, a former NASA astronaut who now supports the agency’s astronaut office. Those lessons, Love said in a meeting last month, stem from a decades-long U.S. government-funded program to search for atmospherically toasted space rocks on the brilliant ice of Antarctica.
