The History of the Fisher Space Pen—From NASA to Everyday Life

During the early NASA missions, astronauts wrote with pencils. In 1965, Paul S. Fisher designed a pen that worked in zero gravity—without funding from NASA, using an investment of about $1 million of his own money.

After rigorous testing, NASA equipped the Apollo mission astronauts with these pens in 1967. About 400 pens were purchased at a price of $6 each. In February 1969, the Soviet Union also purchased 100 Fisher pens and 1,000 refills for the Soyuz spaceflights.

Frequently Asked Questions

At what temperatures does the Fisher Space Pen Cap-O-Matic write?

The Fisher Space Pen Cap-O-Matic writes reliably at temperatures ranging from -34°C to +120°C. This makes it suitable for use in both extreme cold and extreme heat. The ink is thixotropic and won’t freeze in the winter or run in the summer. You can use it in the car, outdoors, or in work environments with extreme conditions.

What kind of ink does the Fisher Space Pen use, and why is it different?

The ink in a Fisher Space Pen is thixotropic—it is solid at rest but liquefies when pressure is applied while writing. The cartridge contains pressurized nitrogen, and a small metal cylinder pushes the ink toward the tip. It is precisely because of this system that the pen writes at any angle, underwater, and in zero gravity. The ink is hermetically sealed, so the pen does not leak or dry out.

What type of refill does the Fisher Space Pen 775-B use?

The 775-B model comes with a black Fisher SPR4 refill and a medium line width. It is compatible with the entire Fisher Space Pen SPR Cartridge series. When the cartridge runs out, it can easily be replaced with a new one from the same series.
