Desirable segment of Kapton foil from the collection of Apollo 11 LMP Buzz Aldrin, attested to as flown on the Command Module Columbia and removed following the mission. The small .75″ x .5″ segment is affixed to a descriptive sheet of Aldrin's unsigned personal letterhead, in full: "The segment placed here was removed from the Command Module Columbia after the first manned. lunar landing mission during July 16 to 24, 1969. This flown segment is from my personal collection. It was part of the thermal protection system that covered the entire outer surface of Columbia. The foil segment traveled nearly 500,000 miles during the Apollo 11 flight and was exposed to the vacuum of space for over 195 hours, including almost 60 hours in lunar orbit." In fine condition.
