The Apollo Lunar Surface Experiment Package (ALSEP) was a collection of scientific instruments stowed on a pallet during transport to the lunar surface. During EVA, the astronauts 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.

This particular artifact has a white cylindrical Passive Seismic Experiment, a Solar Wind Experiment and the Central Station, all undeployed. The experiments varied for each Apollo mission. This package was used by Apollo 15 astronauts for Earth-based EVA training and was transferred to NASM in 1975.
