Pen versus Pencil in Space

The REAL Fisher Space Pen® Story:

When the astronauts began to fly, like the Russians, they used pencils. But the lead sometimes broke and became a hazard by floating in the [capsule's] atmosphere where there was no gravity.  It could float into an eye or nose, or cause a short in the thousands of exposed electrical connections in the spacecraft.   Since the fire on Apollo 1, which three Astronauts died, NASA required a writing instrument that would not burn in a 100% oxygen atmosphere. 

 

In the early sixties, NASA approached Paul C. Fisher, who was familiar with the problems of the early ballpoint pens leaking and drying out, to develop a pen that would not have any of these problems.   Fisher did not think that this could be done and told them so.  Soon afterward, he had a dream; he started working on a pressurized pen with a sealed cartridge.  This led him to develop the first successful pressurized pen.  It took several years and many experiments.  Paul C. Fisher estimates that he spent over one million dollars of his own money.  By July 1965, when NASA approached him again, he was ready.

 

Fisher sent the first samples to Dr. Robert Gilruth, Director of the Houston Space Center at the time.  The sample Space Pens were thoroughly tested by NASA, and passed all tests.  In December 1967 he sold the first Fisher Space Pens to NASA for $2.95 each.  NASA began using the Fisher AG-7 “Anti-Gravity” Space Pen on the October 1968 Apollo 7 mission.
