History of the Fisher Space Pen

During NASA’s early missions, astronauts used pencils. For the Gemini programme in 1965, NASA purchased 34 mechanical pencils at a total cost of $4,382.50. This sparked public outrage due to the high unit price.

Paul S. Fisher of Fisher Pen Co. developed a pen that works in the unique environment of space – without funding from NASA, using around $1 million of his own investment. The pen functioned in zero gravity, underwater and at extreme temperatures.

In 1967, following rigorous testing, NASA equipped the astronauts of the Apollo programme 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 spaceflights. To this day, astronauts and cosmonauts continue to use the Fisher Space Pen.

Frequently Asked Questions

Can the Fisher Space Pen Cap-O-Matic write underwater?

Yes, the Fisher Space Pen Cap-O-Matic is designed to write underwater. The refill contains a pressurised nitrogen gas cartridge which forces the hermetically sealed thixotropic ink through the tip. It does not mix with water and ensures consistent writing even when submerged. This feature makes it suitable for divers, outdoor enthusiasts and anyone working in high-humidity conditions.

At what temperatures does the Fisher Space Pen work?

The Fisher Space Pen Cap-O-Matic works at temperatures ranging from -34°C to +120°C. Standard pens freeze at sub-zero temperatures or run when it’s hot. The Fisher Space Pen uses a special thixotropic ink that retains its properties in extreme cold and heat. This makes it suitable for use in the car, outdoors and in industrial environments.
