The story behind the Fisher Space Pen

During the early NASA missions, astronauts used pencils. In 1965, NASA purchased mechanical pencils for the Gemini project at a cost of $128.89 each, which caused public outcry.

Paul S. Fisher of Fisher Pen Co. developed a new pen with a pressurised ink cartridge – entirely privately funded at a cost of around $1 million, without any support from NASA. The pen worked in zero gravity, underwater and at extreme temperatures.

In 1967, following rigorous testing, NASA equipped the Apollo programme’s astronauts with these pens. Around 400 were purchased at a price of $6 each. In February 1969, the Soviet Union also purchased 100 pens and 1,000 refills for the Soyuz missions. To this day, astronauts and cosmonauts continue to use Fisher Space Pens.

Frequently Asked Questions

What makes the Fisher Space Pen ZGMB different from ordinary pens?

The Fisher Space Pen ZGMB uses a special cartridge with a pressurised nitrogen cartridge and thixotropic ink. Unlike standard pens, it writes at extreme temperatures ranging from -34°C to +120°C, underwater and in zero gravity. The ink is hermetically sealed and does not leak. It writes up to three times longer than ordinary ink. The body is made of brass and steel, and the tip is made of tungsten carbide.

Can the Fisher Space Pen ZGMB write upside down – with the tip pointing upwards?

Yes. This is precisely one of the key advantages of this pen. The pressurised nitrogen cartridge pushes the ink towards the nib regardless of the pen’s orientation. You can write at any angle, including with the tip pointing upwards. This technology was developed specifically for the needs of space missions, where gravity does not exist.

Is the cartridge in the Fisher Space Pen ZGMB replaceable?

Yes, the refill is replaceable. The ZGMB model comes with a black SPR4 refill with a medium line width. When it runs out, you can insert a new refill without having to replace the whole pen. This makes it a long-term investment that will serve you for years to come.

Is the Fisher Space Pen ZGMB suitable as a gift?

Absolutely. The pen comes in an elegant gift box, making it ready to give as a present without the need for additional wrapping.
