1, April 2, 09701:35, the satellite launch time has finally arrived. Dongfanghong-1 left the launch pad with the roar of the engine and the Long March-1 carrier rocket.
At 2 1 48, the star and arrow separated and the satellite entered the scheduled orbit. At 2 1: 50, the National Broadcasting Bureau reported that it had received the music "Dongfanghong" played by China's first satellite, with a clear and loud voice.
1970 On April 25th 18, Xinhua News Agency authorized the world to announce:1970 On April 24th, China successfully launched its first artificial satellite with a perigee of 439 kilometers.
The apogee is 2384 kilometers high, and the angle between the orbital plane and the equatorial plane of the earth is 68.5 degrees. It takes 1 14 minutes to go around the earth. The satellite weighs 173 kg and plays the music of Dongfanghong regularly at a frequency of 20.009 megacycles.
2. Shenzhou 5 went into space.
Shenzhou 5 manned spacecraft is the fifth in the Shenzhou series and the first manned spacecraft launched by China.
It was launched from Jiuquan Satellite Launch Center at 9: 00 on June 5438+00, 2003. It sent astronaut Yang Liwei and a flag of China with special significance into space and returned at 6: 23 on June 10, 2003.
This spaceship marks that China has become the third country to send a human into space after the former Soviet Union (Russian Federation) and the United States. It marks another milestone in China's space technology.
Chang 'e-1 satellite was launched.
Chang 'e-1 is China's first artificial satellite orbiting the moon. Named after Chang 'e, an ancient mythical figure in China, it was developed by China Academy of Space Technology. The total weight is about 2350kg, the dimensions are 2000mm× 1720mm× 2200mm, the unfolded length of the windsurfing board is 18m, and the preset service life is 1 year.
The main detection objectives of the satellite are: to obtain three-dimensional images of the lunar surface; Analyze the content of useful elements on the surface of the moon and the distribution characteristics of material types; Detect the thickness of lunar soil and the space environment from the earth to the moon.
On June 24th, 2007, around 18: 05 (UTC+8: 00), Chang 'e-1 satellite was launched in xichang satellite launch center. On March 1 day, 2009, he finished his mission and crashed into the moon.
4. The world's largest single-aperture radio telescope "Eye of the Sky"
The world's largest spherical radio telescope with a diameter of 500 meters, referred to as FAST, also known as the "eye of the sky", was officially opened in Guizhou karst tiankeng. FAST will maintain the status of world-class equipment in the next 10 to 20 years, and become a "sharp weapon" for astronomical research in China and even the world.
5, nuclear fusion experimental device "artificial sun"
The experimental device of "artificial sun" discharges in ultra-high temperature long pulse plasma, the electron temperature exceeds 50 million degrees, and the duration is 102 second. This great achievement indicates that China continues to be at the forefront of the international research on steady-state magnetic confinement fusion.
