- Chrome Plated Astronaut Space Pen. This is the original Fisher Space Pen that was used on the Apollo 7 space mission in 1968 after 2 years of testing by NASA and has been used on all manned space flights since then. The design and construction of this pen has not changed in 36 years. The pen you buy today is exactly the same as the one taken to the moon in 1969. It is a heavy pen and the weight rests reassuringly in your hand as you write. The AG7 is made from solid brass with an extremely hard Chrome plating. It has a very positive and substantial feeling click mechanism. You press down on the top to extend the refill and press the side button to retract the refill. It’s special design assures you that you’ll always retract the point before you slide it in your pocket. It’s constructed of all brass and steel components of the highest quality and is made in the USA. All Astronaut Pens are attractively packaged in heavy duty gift boxes with flock lining and come with a pamphlet describing the history of the Fisher Space Pen. Used on all NASA Apollo and Shuttle missions, ISS International Space Station, Russian Soyuz and MIR space flights, French ARIANE Space Program, Everest North Face Ski Expedition.

The Secret
The secret behind the unique capabilities of their pens lies in the ink cartridge itself. Their refills are hermetically sealed, pressurized with nitrogen gas, and feature a tungsten carbide ballpoint tip – the same extra hard metal that is used to make armor-piercing ammunition. No longer relying on gravity to write, their pens are able to function at any angle, even upside down! In order to prevent leaks from the gas pressure, their ink has to be thick, thixotropic to be exact. Fisher ink is actually more of a gel than a liquid when it is at rest, with a consistency similar to that of toothpaste. It is only when pressure is applied to the ballpoint that the ink will take on the spreadable properties of a liquid, while still retaining the stickiness needed to adhere to nearly any material.
Facts and History of the Space Pens:
The story of the Space Pen really begins with its inventor, Paul C. Fisher. Before he took to making pens, Paul worked in an airplane propeller factory during World War II. It was there that he gained valuable experience with ball bearings, knowledge that would come in handy down the road for creating ballpoints. He later went on to invent the ‘universal refill’ ink cartridge, which in turn led him to create the first ‘Anti-Gravity’ pen, patented in 1966. Although it is a popular misconception that NASA invested millions of dollars developing an anti-gravity writing instrument, the fact of the matter is that Paul had been working on the design for years. Truth be told, in the beginning Fisher didn’t even set out to create a pen specifically for the astronauts; he was simply looking to make a great pen that worked without leaking.
In the end he had developed what he considered to be the perfect pen – a pen with ink that would not be exposed to air, rely on gravity, leak or dry up, and that wrote underwater and in extreme temperatures. His breakthrough happened to be perfectly timed with the space race and he offered the pens to NASA for consideration. Two years of testing later and the Space Pen was approved to accompany the Apollo 7 astronauts into space. Despite the old joke that the Russians solved their anti-gravity writing problem by using pencils, Russian cosmonauts actually began to carry Fisher Space Pens on their missions as well, at about the same time that NASA did.
