The Auction Sale
On July 15 2026, Sotheby’s held its Space Exploration auction in New York. A dented silver-plastic Duro Rocket felt-tip pen, used by Buzz Aldrin to jury-rig a broken circuit-breaker switch on Apollo 11, sold for $857,600 after competition from five bidders. The lot also included the broken piece of the circuit breaker itself, both items coming from Aldrin’s personal collection.
Apollo 11 Circuit-Breaker Crisis
During the final ascent preparations on July 20 1969, Aldrin’s heavy life-support backpack struck the engine-arm circuit-breaker switch, snapping it off. The breaker controlled power to the ascent engine that would lift the Lunar Module back to orbit. Mission Control could not reroute the power and warned the crew that “there is no way to reroute the power.” Aldrin recalled that he “thought that if I could find something in the LM to push into the circuit, it might hold,” and reached for a black felt-tip pen stored in his personal-preference kit.
Who Was Involved
- Buzz Aldrin – Lunar Module pilot who improvised the fix.
- Neil Armstrong – Mission commander who later described the incident to ABC News.
- Sotheby’s – Auction house that provided the provenance letter and set the pre-sale estimate of $800,000–$1.2 million.

Significance of the Artifact
The pen represents a rare, tangible solution to a life-critical failure on the first lunar landing. Its preservation underscores the improvisational skill of the Apollo crew and offers collectors a direct link to a moment that could have stranded the first humans on the Moon. The sale also arrives as NASA plans a return to the lunar surface by 2028 and as China targets a crewed landing around 2030, highlighting continued public fascination with Apollo memorabilia.
Official Statements & Responses
Sotheby’s described the pen as “the broken piece of circuit breaker, too, as part of the lot” and noted that the item “was not on the official list of items we took to the moon.” Aldrin’s 2016 note to the auction house read, “I still have that broken circuit breaker from Apollo 11 and the felt-tip pen that helped get us off the moon.” NASA’s Houston team later confirmed that “there is no way to reroute the power,” prompting Aldrin’s improvised repair.
Conflicting Accounts
Aldrin’s autobiography attributes the broken switch to his own backpack, while a later letter jokes, “I think Neil broke the switch off and Neil thinks that I broke the switch off.” The two accounts illustrate differing recollections of the moment the switch failed.
Verbatim Quotes
- “The pen did the trick; the circuit breaker held. We could return to Earth after all!” — Buzz Aldrin, *No Dream Is Too High* (2016)
- “My heart jolted a bit … The broken switch had snapped off from the engine-arm circuit breaker, the one vital breaker needed to send electrical power to the ascent engine that would lift Neil and me off the moon.” — Buzz Aldrin, *Magnificent Desolation* (2009)
- “He could’ve picked something that was not very important. But he banged into the circuit breaker that controlled the SM engine that got us back into orbit,” — Neil Armstrong, ABC News interview
- “In the end, what mattered most was that we had to figure out how to solve the problem of the broken switch so that we could leave the lunar surface and get home to Earth.” — Sotheby’s provenance letter, signed by Buzz Aldrin
The pen’s extraordinary price reflects both its rarity and its role in averting a historic disaster, cementing its place among the most coveted artifacts of human spaceflight.
