Think outside the square

When NASA first started sending up astronauts, they quickly discoveredthat ball point pens would not work in zero gravity.

To combat this problem, NASA scientists spent a decade and millions of dollars developing a pen that writes in zero gravity, upside-down on almost any surface including glass and at below freezing to over 3000 C.

The Russians used a pencil.

Great story, but alas untrue. Graphite dust is highly conductive, and in zero-G would be a real menace to any circuity. Like the life support system.

When working on FedSat, the taking of pencils anywhere in the building was forbidden.
