Apollo 11 Most Important Tool
![The original faulty circuit breaker switch from Apollo 11.](https://i1.wp.com/apollo11space.com/wp-content/uploads/2020/02/Untitled-design-2020-02-27T153636.266.jpg?fit=1024%2C576&ssl=1)
Apollo 11 mission to the Moon could have ended in tragedy.
If it weren’t for a tiny felt-tipped pen and the innovative thinking of Buzz, the outcome of the mission to the Moon with Apollo 11 could have ended in disaster.
On 1969 July 20. Neil Armstrong and Buzz Aldrin had gathered lunar rock samples for almost three hours.

When both astronauts were climbing back into the Lunar Module (LM) in preparing to return home, Buzz Aldrin hit the circuit breaker switch with the life support backpack on his suit.
The switch (ENG ARM) initiates the spacecraft’s ascent engine to lift them off the Moon.
![The "Rocket" model felt-tipped marker pen that was carried by Michael Collins Apollo 11 mission.
NASA purchased a number of these pens from the Duro Pen Company for use by astronauts during the Apollo and Skylab program.](https://i1.wp.com/apollo11space.com/wp-content/uploads/2020/02/Untitled-design-2020-02-27T160239.460.jpg?fit=1024%2C672&ssl=1)
NASA purchased several of these pens from the Duro Pen Company for use by astronauts during the Apollo and Skylab program.
So they could meet up with Michael Collins, who was in the Columbia command module circling above.
“He could have picked something that was not very important,” Neil Armstrong said. “But he banged into the circuit breaker controlling the SM engine that got us back into orbit.”
“We’ve got a good complete circuit,'” Buzz Aldrin said
The astronauts informed Mission Control by radio, but they had already disposed of most of their tools aboard to make the module lighter.
![](https://i1.wp.com/apollo11space.com/wp-content/uploads/2020/02/Untitled-design-2020-02-27T160011.306.jpg?fit=1024%2C576&ssl=1)
Using what they had left, a pen, Buzz Aldrin activated the inside switch to engage the circuit breaker and started the engine.
“So, I pushed that in. Houston says, Oh, we’ve got a good complete circuit,'” Buzz Aldrin said.
So the most valuable tool on Apollo 11 seems to be the small pen that brought the astronauts, Neil and Buzz, off from the Moons surface.
Well, that’s it! I hope you enjoyed this article.
