A plastic felt-tip pen used by Buzz Aldrin during Apollo 11 has sold for $857,600 after becoming a symbol of one of NASA’s most remarkable moments.

A simple plastic felt-tip pen used during the historic Apollo 11 mission has sold for $857,600 at a Sotheby’s auction. The pen became famous after astronaut Buzz Aldrin used it to activate a damaged circuit breaker inside the lunar module. The switch had broken, making it impossible to start the engine needed for the return trip from the Moon. Using the pen, Aldrin carefully pressed the circuit, allowing the engine to ignite and helping both him and Neil Armstrong safely leave the Moon. The story shows how a small everyday object played a crucial role in one of history’s greatest space missions. Today, the pen stands as a powerful reminder that quick thinking and simple tools can sometimes make history.
