RADSAT

NSSDCA/COSPAR ID: 1972-076B

Description

The objectives of this spacecraft were to measure background gamma radiation over the whole earth in the 100 to 300-kV range and in the >700-kV range. Fluxes and spectra of low-altitude charged particles were to be measured as a function of time and magnetospheric position. The effects of the space environment on various thermal control coatings were to be determined. Measurements of UV radiation, and H and He atoms and ions were taken. Observation was made of extreme and far UV originating in interaction of solar wind with interplanetary medium or from galactic sources. The cylindrical spacecraft, which was 2.13 m long and 1.37 m in diameter carried a gamma-ray spectrometer, a low-altitude particle measuring sensor, and an extreme UV radiation experiment. The antenna booms extended 2.74 m from each end, coincident with the spin axis.
