What pens do astronauts use in space?

The Fisher Space Pen is a gas-charged ball point pen that is rugged and works in a wider variety of conditions, such as zero gravity, vacuum and extreme temperatures. Its thixotropic ink and vent-free cartridge release no significant vapor at common temperatures and low pressures.

Do ballpoint pens work in space?

NEED FOR A SPACE PEN Ordinary ball point pens did not work in space because the ink would not flow by gravity to the ball and the pen leaked if pressure was created in the ink reservoir (here). NASA used to use pencils, and in 1965 there was controversy over how much they spent on them.

Why do astronauts need pens?

According to the Fisher Space Pen Company, the Apollo 11 astronauts also used the pen to fix a broken arming switch, enabling their return to Earth. Since the late 1960s American astronauts and Russian cosmonauts have used Fisher’s pens. In fact, Fisher has created a whole line of space pens.

Why don’t they use 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.

Why do astronauts not use pencils in space?

Can astronauts use pen in space?

It’s also entirely false. To understand why NASA was so keen on a workable space pen, you have to understand that the pencil is not suited for space travel. The problem is that they have a habit of breaking, shattering, and leaving graphite dust behind.

How does an astronaut pen work?

The space pen works in numerous conditions: upside down, from -50oF to 400oF, in a vacuum, and underwater. The pressurized nitrogen also prevents the air and ink from mixing within the pen so that the ink does not evaporate before use. When the ballpoint moves, the gelatinous ink within the pen becomes liquid.

Can we write in space with pen?

The pencil loses out 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.
