Prognoz 9 was a satellite launched from the Baikonur Cosmodrome on July 1, 1983, using a Molniya-M/8K78M-SOL carrier rocket. The satellite mass was 1060 kg. Orbital parameters attained: highly eccentric orbit periapsis 380.0 km, apoapsis 720000.0 km, period 38448.0 min (26.7 days), inclination 65.5°. The spacecraft was spin stabilized with a period of 113 s. The spin axis pointed towards the Sun, and was repointed every few days.
Investigation of residual radiation from the Big Bang and gamma flares in deep space, and solar corpuscular and electromagnetic radiation plasma flows and magnetic fields in circumterrestrial space to determine the effects of solar activity on the interplanetary medium and the earth's magnetosphere. In addition to Soviet scientific apparatus, carried instruments built in Czechoslovakia and France.
