What an odd thing to memorialize - but there it is. The 50th anniversary of the first (and last) corned-beef sandwich to fly through space. Back on the 23rd of March, 1964, NASA launched their first two-man space mission Gemini 3. Two hours into the flight, astronaut John Young pulled a corned beef sandwich out of his space suit pocket. It was a joke, or a "gotcha" as his partner called them - but a joke that turned deadly serious not long after his epic sandwich-heavy space-prank was revealed.
