Nasa

[ChrisCantSkate]

When NASA first started sending up astronauts,
they quickly discovered that ball-point pens would
not work in 0 gravity. To combat this problem, NASA
scientists spent a decade and $12 billion developing
a pen that writes in 0 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.
