Chrome Plated Astronaut Space Pen with Commemorative Moon Landing Engraving. 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. 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.
