During the heat of the space race in the 1960's, NASA decided it needed a ball point pen to write in the zero gravity confines of its space capsules.  After considerable research and development, the Astronaut Pen was developed at a cost of $1 million U.S.  The pen worked and also enjoyed some modest success as a novelty item back here on earth.

The Soviet Union, when faced with the same problem, used a pencil!
