Find the parameters of the first satellite in each country.

Dongfanghong-1 satellite is the first artificial earth satellite launched by China on April 24th, 1970. According to the time at that time, China was the fifth country in the world to launch domestic satellites with homemade rockets after the Soviet Union, the United States, France and Japan. [Edit this paragraph] Main parameters: satellite quality: 173kg.

Satellite shape: spherical 72-sided, diameter 1 m.

Perigee: 439 km

Apogee: 2384 km

Objective: To play the music "Dongfanghong" [Edit this paragraph] The current state of the satellite is written according to the data of February/KOOC-0/day/KOOC-0/5: 08: 32, 2009.

Latitude: 64.02 degrees

Longitude: 35.07 kilometers

Track inclination: 205.64 degrees.

Operation period: 1 10.6 minutes.

Speed: 7.55 km/s

Height: 728.25 km

Perigee: 430 km

Apogee: 2075 km

Satellite real-time status tracking:/? S=4382 (As of 20 1 1: 39 on March 6th, Beijing time, the satellite is entering China from Mongolia) [Edit this paragraph] The instrument cabin on the equipment satellite is equipped with power supply, radar transponder for orbit measurement, telemetry device, electronic tone generator and transmitter, scientific test instruments, etc. The main task of the satellite is to play the music "Dongfanghong" into space, and at the same time carry out satellite technology experiments to detect the ionosphere and atmospheric density.

Satellite uses silver-zinc battery as power supply, and the service life of the battery is limited. After 28 days of satellite operation (design life is 20 days), the battery is exhausted, the music of "Dongfanghong" stops playing, and the satellite ends its working life. However, the orbital life of the satellite is not over. According to the orbit calculation, it can run in space for hundreds of years (without any accident).
