Launched in the early 1970s.

The Dongfanghong-1 satellite proposed a pre-research plan in 1958, officially began development in 1965, and was successfully launched from the Jiuquan Satellite Launch Center on April 24, 1970. The Dongfanghong-1 satellite weighs 173 kilograms and was launched by the Long March-1 carrier rocket into an elliptical orbit with a perigee of 441 kilometers, an apogee of 2,368 kilometers, and an inclination of 68.44 degrees.

The satellite carried out orbit measurement and control and broadcast the music "The East Is Red". The Dongfanghong-1 satellite works for 28 days (design life is 20 days). The satellite stopped transmitting signals on May 14. The Dongfanghong-1 satellite is still operating in space orbit.

Overall design

Dongfanghong-1 satellite consists of structure, temperature control, energy, "Dongfanghong" music device, shortwave telemetry, tracking, antenna and other subsystems and attitude measurement components. Its main mission is to conduct satellite technology experiments and detect the ionosphere and atmospheric density.

On August 2, 1965, the Central Special Committee officially approved the development project of Dongfanghong-1 satellite, and at the same time proposed the overall technical plan of the satellite as "can go up, can be grasped, can be heard, and can be seen" ".
