Apollo 11, launched July 16, 1969, marked the first manned lunar landing mission. Neil Armstrong and Buzz Aldrin lived on the Moon for 21.6 hours (2 hours and 31 minutes of which were outside the Lunar Module Eagle) while Michael Collins orbited the Moon inside the Command Module Columbia.

The attached is a swatch of very thin pressure-sensitive Kapton polyimide tape cut by North American Recovery Team member Ossie Reid from Columbia's thermal protection subsystem. Applied over the external ablator surface, the tape was coated with aluminum and oxidized silicon monoxide to protect the spacecraft from the extreme temperatures of outer space.
