Farewell Atlantis: NASA counts down to the last launch

NASA has begun counting down to its last scheduled launch of the space shuttle Atlantis. We wanted to know: Do all the shuttles have the same type of cup holders and is taking off on Atlantis any different from launching in Discovery?

Jerry Ross is a seven-time astronaut and has spent five missions aboard Atlantis; Colonel William Pailes was aboard the very first Atlantis mission and helps us sort out the really important questions about outer-space exploration.
