XICHANG, March 10 (Xinhua) -- With a Long March-3B rocket putting a new communication satellite into orbit on Sunday, China's Long March carrier rocket series completed 100 launches, having sent more than 100 spacecraft into space since 1970.

"This is a milestone for China's space industry development," said Wu Yansheng, board chairman of the China Aerospace Science and Technology Corporation (CASC).

The Long March carrier rocket series, developed by CASC, are responsible for about 96.4 percent of all the launch missions in China.

It took 37 years for the Long March rockets to complete the first 100 launches, 7.5 years to complete the second 100 launches, and only about four years to accomplish the final 100, with the average number of launches per year increasing from 2.7 to 13.3 and then to 23.5.

"Intensive launches have become normal in China, indicating the rapid development of the space industry, the progress of science and technology and the enhancement of national strength," said Shang Zhi, director of the Space Department of the CASC.
