Service Module
Sector 1 housed the Scientific Instrument Module (SIM) bay for this third
Apollo J mission. Three new experiments were carried in the SIM bay on this
mission:
Lunar Sounder : Electromagnetic impulses beamed towards the lunar surface in the high frequency (HF) and very high frequency (VHF) bands would provide recorded data for developing a geological model of the lunar interior to a depth of 1.3 km (4280 ft.). In addition to stratigraphic, structural, tectonic and topographic data on regions of the Moon overflown by Apollo 17, the lunar sounder measured the ambient electromagnetic noise levels in the lunar environment at 5, 15, and 20 mHz and the occultation by the Moon of electromagnetic waves generated at the lunar surface by the electrical properties experiment transmitter. Infrared Scanning Radiometer (ISR) : The purpose of the ISR experiment was to measure lunar nighttime temperatures and cooling rates. Far-ultraviolet Spectrometer : The far-UV spectrometer was used in an attempt to measure ultraviolet emissions from the scarce lunar atmosphere. The far-UV spectrometer was mounted on the bottom shelf of the SIM bay and had an external baffle which limited stray light. Controls for activating and deactivating the experiment and for opening and closing a protective cover were located in the CM. Also mounted in the SIM bay were the panoramic camera, mapping camera and laser altimeter. Description of these instruments can be found with Apollo 15. From Apollo 17 Press Kit.
