EP-95 ON THE MOON WITH APOLLO 16
FIGURE 58.-SIM Bay. Shown here is the
location within the scientific instrument module (SIM) of the
equipment for each orbital experiment. The sensors for the gamma ray
spectrometer and the mass spectrometer both extend outward on a boom
about 25 feet when the instruments are in use. The subsatellite is
launched while the service module is in orbit around the Moon; it
remains behind in orbit after the astronauts leave lunar orbit to
return home. Before the CM is separated from the SM the film
cassettes must be retrieved. NASA PHOTO S-72-16862.
