Fisher's Space Pen was developed for use in gravity free environments. The cartridge, pressurized with nitrogen, seals out air preventing evaporation and oxidation of the ink. Internal pressures force ink outward toward the ball point. A thixotropic ink is used. The pen will operate from minus 50 to plus 45 degrees Fahrenheit, and will withstand atmospheric extremes. It was used both on the Apollo missions and by Soviet Cosmonauts.
