Unified S-Band Data Handling System

The data handling portion of the Unified S-Band tracking system consists of three readily separable subsystems. These are: a) the Timing System, b) the Antenna Position Programmer, and c) the Tracking Data Processor. Each of these subsystems is briefly described below

Lunar orbital mass spectrometer experiment

The design, development, manufacture, test and calibration of five lunar orbital mass spectrometers with the four associated ground support equipment test sets are discussed. A mass spectrometer was installed in the Apollo 15 and one in the Apollo 16 Scientific Instrument Module within the Service Module. The Apollo 15 mass spectrometer was operated with collection of 38 hours of mass spectra data during lunar orbit and 50 hours of data were collected during transearth coast. The Apollo 16 mass spectrometer was operated with collection of 76 hours of mass spectra data during lunar orbit. However, the Apollo 16 mass spectrometer was ejected into lunar orbit upon malfunction of spacecraft boom system just prior to transearth insection and no transearth coast data was possible
