The world's best chef is cooking for astronauts. But what is it like dining in space?
It's not certain whether Yuri Gagarin actually said, "This is one small nibble for man, a giant bite for mankind," shortly before becoming the first human to eat in space, but for the purposes of a convenient, introductory soundbite we will assume he did. Just as the Vostoc 1 spacecraft that made Gagarin the first human to fly in space would seem Neolithic in comparison to today's shuttles, space food has both literally and metaphorically come a long way in the past 45 years.
