If you're making the last-ever trip on the space shuttle, you want to make it count.
And if the list put together by collectSPACE.com is any indication, this last flight is taking along enough souvenirs to outfit a small army.
Almost all the items are put there by NASA to pass out later to foreign governments, support teams, contractors, politicians, anyone. The items fly in a (very, very tightly packed) duffel bag that stays stowed away the entire flight.
Each astronaut gets to take a small amount of personal items, as well.
What's going up on Atlantis:
6. Flags. Lots of Flags Almost 22,000 flags, by our count -- U.S. flags, state flags, flags of Russia, Japan, Canada and the other countries that have had shuttle astronauts, lots of flags. Including ones from NASCAR and the Texas Motor Speedway.
