Why didn’t astronauts use a pencil in space?
The pencil wasn’t an ideal choice for writing in space because its tip could flake and break off, drifting in microgravity with the potential to harm an astronaut or an equipment. Apart from this, pencils are flammable, and NASA wanted to avoid anything flammable aboard a spacecraft.

Are space pens worth it?
Like I said, Fisher Space Pens are an easy recommendation if you’re looking for a relatively inexpensive, write-anywhere option.

Do normal pens work in space?
Here’s why astronauts can’t use regular ballpoint pens: Because ordinary pens rely on gravity. In space, of course, there isn’t enough gravity to force the ink out, so the pen’s reservoir needs to be pressurized.
How many people have died going to space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
Do space pens leak?
Nope. Paul Fisher at the Fisher Pen Company had already been working on a pressurized pen. But the pressure caused the pens to leak. When NASA reached out to him looking for a pen that didn’t require gravity, he knew this pressurized ink cartridge could be just the thing – if he could solve the leaks.
Does the Fisher Space Pen write well?
