When NASA first started sending up astronauts,
they discovered that their ball point pens would
not work in zero gravity.

To overcome this small problem, NASA scientists
spent three years and $7 million to develop a pen
that would write in zero gravity, upside down, on
almost any surface and at any temperature.

(guess that's why the Russians used a pencil)
