The tips flaked and broke off, drifting in microgravity where they could potentially harm an astronaut or equipment. And pencils are flammable–a quality NASA wanted to avoid in onboard objects after the Apollo 1 fire.

The problem is that they have a habit of breaking, shattering, and leaving graphite dust behind. The wood, too, can make it a serious fire risk in the pressurized, oxygen-rich capsule.
Is graphite harmful to the environment?

Can you write in space?
Several instruments have been used to write in outer space, including different types of pencils and pens. … NASA tested and approved the pen for space use, then purchased 400 pens at $6 per pen. The Soviet Union subsequently also purchased the space pen for its Soyuz spaceflights.
Why does pencil lead stay in your skin?
