The Apollo Lunar Surface Experiment Package (ALSEP) was a collection of scientific instruments folded up and stowed on pallets during transport to the lunar surface. During EVA, the astronauts removed and transported the various "sub-packages" to selected sites near the Lunar Module and deployed the instruments on the lunar surface. Each experiment was electrically connected to the Central Station of the ALSEP. An antenna on the Central Station allowed communication with Earth. The experiments varied for each Apollo mission.
This particular package (ALSEP deployable subpackage 1) carried mock-ups of several of the experiments to be deployed by the Apollo 17 astronauts, including the Lunar Surface Gravimeter and Lunar Ejecta and Meteorites Experiment and was used by the astronauts during the months of training leading up to launch. NASA declared the training devices surplus in June 1973 and transferred them to the Museum in 1975.
