The company that makes the space pen company (Fisher Pen Company),Last year celebrated the 50th anniversary of the Apollo 7 mission (first flight in 1968).

Since the space pen first entered space, it has been widely used during space flight and space station missions.

After years of development, Fisher has created many different shapes and models for various purposes.Despite the variety of styles, the high technology behind it is as always.

To make this pen work in a zero-gravity environment, you need to use the core component of the pressurized ink tank. Paul Fisher, founder of Fisher, won the patent in 1966.

The pressurized ink cartridge uses a "thixotropic ink".

The agitation action of turning it into liquid ink depends on the ball rolling at the nib. When you walk, this action makes the ink very thin and allows it to flow under zero gravity.

The main motivation for developing this technology is to make it available in space.Given its ability to be inverted on most surfaces, it was eventually extended to more scenes (such as water use).
