ALSEP was a collection of geophysical instruments continue to
monitor the environment of each Apollo landing site for a period
of at least a year after the astronauts had departed. Designed
for a life of one year (Apollo 17 was for two), they ended up
working for up to 8 years, the experiments permanently shut down
by Mission Control on 30 September 1977. Due to the experimental
nature of the first landing of Apollo 11, especially the
mechanics of getting to the lunar surface and back, science took
a lesser role, so Apollo 11 had a simpler version known as the
Early Apollo Surface Experiments Package (EASEP), with only two
experiments. The ALSEP/EASEP packages were stowed in (SEQ
Bay)/Quad II during the flight from Earth. The height of the
pallets was at the limit for easy manual deployment on level
terrain. There were booms to help with off-loading, particularly
if the Lumar Module was tilted in such a way that the Bay was
higher than normal. Lanyards were release the packages and allow
them to swing free an
