The Fisher Space Pen has been touted as NASA’s go to writing device for decades. There was an urban legend that NASA spent millions developing a pen that could write in space. The truth is, NASA spent $0 towards the developemnt and the switch from pencils was actually a cost saving move. A great success of ingenuity in manufacturing to produce a resilient product. Fun video showing all the steps in the manufacturing process.
You can learn more about the Space Pen from Wikipedia:
The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is able to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in a very wide range of temperatures.
