The Truth About the Million-Dollar Space Pen

In the 1960s, NASA faced challenges writing in space, initially using pencils like the Soviets. However, pencils posed risks like flammability and debris. Paul C Fisher invented the AG7 Anti Gravity pen, which used a pressure ink cartridge and non-Newtonian fluid to write in microgravity. NASA adopted it in 1968, and it became a staple for astronauts and cosmonauts. Despite myths, the pen wasn't used in Apollo 11's emergency; a felt-tip marker was. The space pen remains a symbol of innovation.
