China on early morning of June 1, at the Xichang Satellite Launch Center in southwest China’s Sichuan Province, successfully launched “SinoSat-3”, a communication satellite, aboard a Long March 3-A carrier rocket, marking the 100th flight of its Long March series.

The “Long March” carrier rockets fall into four series with 12 models, which can launch spaceships and a range of satellites into low, medium and high orbits. The 100th launch demonstrates that “Long March” rockets have become China’s high-tech products having independent intellectual property rights and powerful international competitiveness.

Since the successful launch of China's first man-made satellite Dong Fang Hong I aboard “Long March 1” rocket on April 24, 1970, “Long March” carrier rockets have developed from utilizing conventional propellants to low-temperature propellants, from serial rocket staging to parallel rocket staging, from one satellite aboard a single rocket to multiple satellites aboard a single rocket. Currently “Long March” has four series: “Long March 1”, “Long March 2”, “Long March 3” and “Long March 4”.

China’s “Long March” carrier rockets have before successfully launched China’s first man-made satellite, first recoverable satellite for science research purpose, first communication satellite and first manned spaceship, and have for many times launched foreign commercial satellites, occupying a significant position in international market of launching commercial satellites.
