This is the storage and handling base for the Apollo Lunar Surface Drill (ALSD). This unit is similar to those flown on the Apollo 15, 16, and 17 missions and was used for training. Its purpose was to stow the ALSD and to provide a tripod on the lunar surface. Three deployable legs allowed the hardware to stand on the lunar surface. This allowed the astronaut access to the drill, drill bits, wrench, and handle, which were stored on the unit.
The base was transferred to the Smithsonian as part of a large collection of training equipment in 1974.
Transferred from NASA, Johnson Space Center.
