Storm 1 rocket and long space 1 satellite

The first public flight of this new type of "storm one" launch vehicle was on July 26, 1975. It successfully put a new technology test satellite "long sky one" with a self weight of 1107 kg into the scheduled orbit. This is also the first successful record of the new China Aerospace Department launching a satellite larger than 1000 kg into the sky, because none of the previously launched satellites in China has 1000 kg. Subsequently, the relevant departments of our country carried out launch tests on this type of rocket in 1975, 1976, 1977 and 1978 for four consecutive years, which basically achieved a complete success! During this period, in the test of this type of rocket, our country has carried out extensive tests on some of the rocket technologies, especially the first and second stage separation technology of the rocket, the high altitude rocket engine start technology, the high altitude stability and inertial attitude technology of the second stage rocket, the rocket load re-entry atmosphere protection technology, etc., which has been successfully tested for the next generation of new carrier rocket "Dongfeng" The South Pacific flight that shocked the world of "Five" laid a good foundation!
