Passive Seismic Experiments Package (PSEP) de-
ployed on the moon's surface. Two packages were
left on the moon for scientific purposes. The PSEP
is to record moonquakes or other disturbances.
The Laser Ranging ketro-Reflector is to measure
the exact distance of the moon from the earth.
Astronauts' footprints on the lunar surface are in
evidence.
While this equipment was left on the moon, the
astronauts brought back 2 boxes of lunar rocks
for scientific research. The first close-up exam-
ination of moon rocks and dust created excitement
