A History of the Fisher Space Pen

A History of the Fisher Space Pen

fisher 3Developed by Paul Fisher in 1965, the Fisher Space Pen was extensively tested by NASA and in 1967 they agreed to equip their astronauts with this unique ballpoint space pen.  The Soviet Union soon followed and the Fisher Space Pen was used on the Soyuz space flights.

This exceptional ballpoint pen writes on almost any surface, in temperatures between 25°C and 120°C. Initially nitrogen was used to pressurize the ink cartridge allowing the user to write in zero gravity, further development uses thixotropic ink which is in a semi solid state turning to liquid when movement transpires.  The Fisher Space Pen is not affected by dirt or grease and can be used on coated plastics, carbonless paper, metal duct work, camera film, on wet surfaces, at any angle and even under water making it the perfect pen for astronauts, divers, climbers, the military, the police force, fire fighters, art and design and for those of us who just want an extraordinary writing instrument.

In the first instance the space program used lead pencils which came with their own problems. The lead pencil points would break off and turn into a floating hazard in the spacecraft’s atmosphere where there was no gravity. Complications occurred for example shorting out electrical equipment, inhalation of pencil shavings or a small piece of pencil lead accidentally floating into an eye, but even more so the fact that wood and lead are prone to burning in an atmosphere of pure oxygen were reason enough to look for alternative measures.

In July 1969 the Fisher Space Pen AG7 accompanied Buzz Aldrin, Neil Armstrong and Michael Collins to the moon in Apollo 11.

The Fisher Space Pens were also used in the Skylab which orbited the earth from 1973 until 1979.  NASA modified the Fisher space pen adding Velcro and a clip for easy access and storage.

In 1983 President Ronald Regan used a Fisher Space Pen to sign the Proclamation of Air and Space Bicentennial celebrating the 1783 first manned flight in a hot air balloon over Paris, France by Etienne de Montgolfier.

In 1997 the Everest North Face Ski Expedition used Fisher space pens to write in extreme temperatures.

In 1998 Fisher space pens were used on the Russian Space Station Mir.

The USA, the Soviet Union and France continue to use the Fisher Space Pen.

The shelf life of a Fisher Space Pen is one hundred years whereas the normal ballpoint has a shelf life of two years.
