Dongfanghong I (Red East 1), also known as China 1, was the People's Republic of China's first space satellite, launched successfully on 24 April 1970 (after one failed attempt on 16 November 1969) as part of the PRC's Dongfanghong space satellite program. At 173 kg, it was heavier than the first satellites of other countries. The satellite carried a radio transmitter which broadcast the song of the same name, Dongfanghong or "The East Is Red." The broadcast lasted for 26 days while in orbit.

The satellite remains in orbit. As of 24 January 2015 it was in an orbit with a perigee of 442 kilometers, an apogee of 2,046 kilometers and inclination of 68.42 degrees.
