Magnetic deflection ion mass spectrometer experiment for atmosphere explorer

The magnetic ion mass spectrometer was carried aboard Atmosphere Explorer C and Atmosphere Explorer D. The instrument measures the relative abundance of ionic species with very high sensitivity and very high mass resolution. Thus isotopic ratios for various ion species can be examined and minor ion species such as O(++), N(++), and H(+) can be detected when their relative abundance is very small. These instruments functioned with no critical internal failures but the premature loss of the AE-D spacecraft after only a few months of operation has led to an emphasis of scientific achievement from AE-C. The very long lifetime of AE-C coupled with the prolonged time that this spacecraft spent near the F-region peak led to the accumulation of very large count numbers in the channeltron detectors

Real-Time Operating System/360

RTOS has a cost savings advantage for real-time applications, such as those with random inputs requiring a flexible data routing facility, display systems simplified by a device independent interface language, and complex applications needing added storage protection and data queuing

Study of outgassing and decomposition of Space Shuttle heat protection tiles, fillers and adhesive

A purge and trap technique which was employed to collect and separate the chemicals desorbing from the space shuttle heat protection tiles is described. The instrumentation included a mass spectrometer and gas chromatograph
