Sotheby’s to Auction Historic Apollo 11 Artifact
The felt-tip pen used by astronaut Buzz Aldrin to repair a critical circuit breaker during the 1969 Apollo 11 mission will be sold at auction in New York this Wednesday. Sotheby’s estimates the sale price for the pen and the associated broken circuit breaker switch to range between $800,000 and $1.2 million.
The mechanism of the repair involved Aldrin using the non-conductive felt-tip pen to manually engage the engine-arm circuit breaker after the original switch snapped off inside the lunar module. This action restored electrical power to the ascent engine, which was essential for the crew to depart the lunar surface and return to Earth. The item originated from Aldrin’s personal collection and serves as a primary artifact of the mission’s technical contingency.
The auction occurs as global interest in lunar exploration intensifies, with NASA targeting a return to the lunar surface by 2028 and international competitors aiming for crewed landings by 2030. The sale marks a significant transfer of space-flight history from the personal possession of the Apollo 11 crew to the private collector market.
