S72-53949 (November 1972) --- The upper and bottom sections of the Lunar Neutron Probe Experiment (S-229), in a stowed configuration, which will be used at the Taurus-Littrow landing site by the Apollo 17 crewmen. The purpose of this experiment is to measure neutron capture rates in the lunar regolith, measure variation of neutron capture rates as a function of depth beneath the lunar surface, and gain information on the lunar neutron energy spectrum.
