The "Space Pens" were first developed in 1948 by Paul Fisher for NASA so that astronauts could write without the help of gravity. They write upside down and also in water because of their special pressurised ink cartridge. The Russians used a pencil back in the space race days however now they also use the Fisher Pens! The classic bullet design is cited as an outstanding example of industrial art and is exhibited in the New York Museum of Modern Art.
