When NASA first started sending up astronauts, they quickly discovered that ball-point pens would not work in zero gravity.
To combat this problem, NASA scientists spent a decade and $12 billion developing a pen (which became eventually the Fisher Space Pen) that writes in zero gravity, upside down, on almost any surface including glass and at temperatures ranging from below
freezing to over 300 C.
The Russians used a pencil.
