Great Scott (lunar sample)

Great Scott is currently stored at the Lunar Sample Laboratory Facility at the Lyndon B. Johnson Space Center. Pieces of it are on display at the National Museum of Natural History in Washington, DC, the Tellus Science Museum in the state of Georgia, the Madrid Deep Space Communications Complex in Spain, the LROC Lunar Exploration Museum at Arizona State University and the Science Museum in London, England.

The term Great Scott was in use as soon as the next mission, Apollo 16, because Charlie Duke used the term just before picking up Big Muley. Big Muley is the largest sample (11.7 kg) returned from the Moon, and Great Scott is the second largest.
