For Sale: Apollo Command Module LiOH Canister
  • Identical to flight elements, and marked by hand with the number “15” for loading in the Command Module. About 30 canisters were loaded per mission.
  • This type of element (-0051) was replaced quickly with -0061, identical except that a sample of the LiOH was taken and packaged before assembly.
  • Dated "FEB 19 '69". Measures 7 1/8" x 7 1/8" x 5 1/4" and weighs about 8 pounds.
  • A green/aluminum Airesearch label on the side reads: "ABSORBER ELEMENT CO2, Part 813540-2-1, Serial 108-345, Order NAS-9-150, NASA 00400 0108345, Ref Spec ME901-0218-0051."

During the Apollo 13 mission the astronauts were stranded in the Lunar Module for much of the mission. Using instructions from the ground they improvised a way to adapt the Command Module carbon dioxide absorbers for use in the Lunar Module. Otherwise the increased amount of carbon dioxide in the cabin air from the astronauts own breathing would have killed them.

Photo below shows a Command Module carbon dioxide absorber element placed in the Apollo 13 Lunar Module "Aquarius" with the improvised adapter, made by the Apollo 13 astronauts. (NASA photo)
