Because "Dongfanghong-1" was not equipped with an automatic power control switch, the solar panel failed to open shortly after launch, so it has already failed. But its feat will go down in history forever-China people's dream of flying to the vast universe began.
On April 24th, 1970, the "Dongfanghong-1" satellite was launched from Jiuquan Satellite Launch Center in the northwest of China. After the launch, the orbit of the satellite is 439 kilometers from the nearest point of the earth and 2384 kilometers from the farthest point of the earth. The included angle between the orbital plane and the equatorial plane of the earth is 68.5 degrees, and the period of one circle around the earth is 1 14 minutes.
The main task of "Dongfanghong-1" satellite is to carry out satellite technology experiments to detect the density of ionosphere and atmosphere. The designed working life is 20 days (actual working life is 28 days), during which telemetry parameters and various space detection data are transmitted back to the ground, and the signal transmission is stopped on May 14 of the same year.
