Prognoz 9



This spacecraft was one of a continuing series to measure electromagnetic radiation, magnetic fields, plasma, and charged particles. Although the specifics on all experiments are not available, it is known that a hard X-ray spectrometer, a magnetic field measuring experiment, and an 8-mm radio telescope were flown on Prognoz 9, and possibly a plasma experiment was also on board. The spacecraft was spin-stabilized, with a period of approximately two minutes, and the spin axis was oriented toward the sun. The initial apogee distance was 720,000 km, and the period was 27 days.
