The Space Pen

came up in conversation on an email list and someone pointed out a link to Snopes: bq. Claim: NASA spent millions of dollars developing an "astronaut pen" which would work in outer space while the Soviets solved the same problem by simply using pencils. bq. Status: False. bq. Examples:
During the space race back in the 1960's, NASA was faced with a major problem. The astronaut needed a pen that would write in the vacuum of space. NASA went to work. At a cost of $1.5 million they developed the "Astronaut Pen". Some of you may remember. It enjoyed minor success on the commercial market. The Russians were faced with the same dilemma. They used a pencil.
Here is the straight story from Fisher: bq. NASA never asked Paul C. Fisher to produce a pen. When the astronauts began to fly, like the Russians, they used pencils, but the leads sometimes broke and became a hazard by floating in the [capsule's] atmosphere where there was no gravity. They could float into an eye or nose or cause a short in an electrical device. In addition, both the lead and the wood of the pencil could burn rapidly in the pure oxygen atmosphere. Paul Fisher realized the astronauts needed a safer and more dependable writing instrument, so in July 1965 he developed the pressurized ball pen, with its ink enclosed in a sealed, pressurized ink cartridge. Fisher sent the first samples to Dr. Robert Gilruth, Director of the Houston Space Center. The pens were all metal except for the ink, which had a flash point above 200°C. The sample Space Pens were thoroughly tested by NASA. They passed all the tests and have been used ever since on all manned space flights, American and Russian. All research and developement costs were paid by Paul Fisher. No development costs have ever been charged to the government. One more myth busted... Posted by DaveH at February 18, 2005 9:32 PM
