Buzz Aldrin's Surprise Paperwork From Moon Mission

Astronaut shares customs form he had to fill out after mission.

The American astronaut has been sharing some of his travel documents from his 1969 moon landing mission. While some of the information on the forms is routine, other areas yield surprising insights about Aldrin's historic trip.

(The crew was kept in quarantine for three weeks after their return to Earth as a precautionary measure.)

Also intriguing: For such a long journey, Aldrin only claimed $33.31 in travel expenses for his trip -- likely expenses from his time traveling on the ground before and after the trip. He noted in a "schedule of expenses" form he shared that "government meals and quarters" were furnished for the journey.
