Intercosmos 6



Intercosmos 6 was the first of a series of second generation Intercosmos research satellite to be launched. It was larger and heavier than the previous five Intercosmos satellites and weighed nearly 1825 kg. It carried a scientific package, weighing more than 1044 kg, that consisted of experiments that were joint ventures of the COMECON East Europe bloc. The main instrument on board was an ionization calorimeter assembled by the Soviets with components supplied by Hungary, Poland, Czechoslavakia, and Romania. Also included was a multilayered silver bromide photographic emulsion designed to track high-energy cosmic radiation, as well as electronic equipment to detect, identify, and measure this radiation. Experience gained from the heavy proton satellite series was used in the construction and design of Intercosmos 6. The satellite measured (1) primary cosmic radiation with energies from 10 to the 12 power to 10 to the 13 power ev, (2) the chemical composition and energy spectra of high-energy radiation in space, and (3) meteoroid particles. The satellite returned to earth after only 4 days in orbit and was recovered intact. The low altitude of the flight and the 4-day duration were both chosen to collect optimum data, i.e., to stay below the Van Allen radiation belt and thus prevent too much radiation from passing through the emulsion.
