Buzz Aldrin, fashion model? The 86-year-old former astronaut will walk in a fashion show at New York's Men's Fashion Week Jan. 31, Page Six reports. Designer Nick Graham, former CEO of Joe Boxer, is presenting a Mars-themed collection complete with "space-oriented formal wear," sources say, so it only makes sense for Aldrin to take part. (There will also be a video narrated by Bill Nye.) Aldrin thinks we should colonize Mars, and Graham is interested in what we'll wear when we do. Aldrin's official word on the matter: "I've walked on the moon, so how hard can it be to walk in a fashion show?" (More Buzz Aldrin stories.)
