Although not as famous as the Fisher space pen, this lightweight aluminum felt-tip marker pen was really the pen the saved the Apollo mission. See the pen that was donated to the Smithsonian Museum that helped Buzz Aldrin fix the broken breaker switch that saved the Apollo 11 mission. This pen is the real deal, made by the Duro Pen Company that was used on Apollo Missions.History & the Smithsonian Museum don't lie. In 1969, Larry Sitten was working as the customer service manager at Duro Pen Co. A small, but well-known pen supplier in Brooklyn, when he received a call from NASA? S felt-tip marker from a department store on the way to work, and NASA discovered that the marker wrote without gravity.
It was because in the marker they had a wadding of cotton material, and the ink is absorbed in that capillary action, taking the ink away, ? S marker would allow the astronauts to write in space. Which then had to be individually numbered for the Apollo 11 mission, according to Sitten. But what looked like smooth sailing to those watching back home on Earth was actually one pen away from tragedy. When the shuttle landed on the moon?
S surface, the circuit breaker? S switch accidentally broke off. They knocked off the circuit breaker while they were headed out to walk around the moon, ? A broken circuit breaker meant there was no way to start their ascent engine to get them off the moon. Quick on his feet, astronaut Buzz Aldrin reached into the pocket of his spacesuit and pulled out the Duro felt-tip marker.
But the plastic tip of the Duro felt-tip marker was nonconductive. And so Aldrin was able to stick the marker in the circuit breaker and start the switch. Had it not been for that 69-cent marker, the astronauts might still be on the moon. Today, that lifesaving marker is sitting in a display case in the Smithsonian National Air and Space Museum.
