Associated space launch
Dong Fang Hong 1 (DFH-1) was the first Chinese satellite. This was the first satellite launched by China on its own booster, making China the fifth nation to put a spacecraft into orbit using its own rocket. The satellite was developed under the direction of Tsien Hsue-Shen, dean of the Chinese Academy of Space Technology (CAST). The experimental satellite was a nearly spherically shaped symmetrical 72-faced polyhedron with a 1-meter diameter. It was battery-powered and carried a radio transmitter. The primary mission was to broadcast the song "Dong Fang Hong", paying tribute to Chairman Mao, and to announce the time. A total of five identical satellites were built to have backups in case of launch failures. The first satellite launched successfully.
DFH-1 was lifted into orbit during the mission ‘Long March 1 | Dong Fang Hong 1’, on board a Long March 1 space rocket.
The launch took place on April 24, 1970, 1:35 p.m. from Launch Area 2A.
