1982-118A
DMSP satellite 17540 (S-6) was the first of an upgraded series, the Block 5D-2. For this spacecraft, the Thor/Star 37XE launch vehicle was replaced with a refurbished Atlas E ICBM. The 5D-2 retained the integral Star 37S kick stage to circularize the orbit. The first 5D-2, DMSP Block 5D-2 S-6, was launched on 1982 Dec 20 to becom F-6. In addition to the OLS weather imager, F-6 (17540) carried a vertical temperature profile radiometer, and three instruments to study energetic processes in the ionosphere - an electron spectrometer, an X-ray spectrometer and a plasma monitor.
