The Space Pen range made by Fisher Space Pen Co. (USA) use special nitrogen-pressurised cartridges to dispense visco-elastic ink. This allows these pens to work perfectly upside down, and under a wide range of environmental conditions including extreme heat and cold, underwater and even the zero gravity of space. They were first used in space on the Apollo 7 mission in 1968 and have become the standard pen for astronauts, including those currently working on the International Space Station.
