WINGS OF MARS

摘要

An invasion of Mars begins in December. Spacecraft from the U.S. and the European Union will descend upon the Red Planet. Rovers will creep across the surface, collect soil samples, and look for the thus-far elusive signs of life—past or present. To really cover the territory, however, you need some kind of aircraft. And in the thin Martian atmosphere, getting anything to fly means using wings so long and fragile that they probably wouldn't make it to Mars in one piece.
