When NASA first started sending up astronauts, they
quickly discovered that ballpoint pens would not work
in 0 gravity. To combat this problem, NASA scientists
spent a decade and ผ billion developing a pen that
writes in zero gravity, upside down, underwater, on
almost any surface including glass and at temperatures
ranging from below freezing to over 300 C.

The Russians used a pencil.
