3 (1)Mission of CASC Make into space much easier The number of launch for Changzheng-series rockets breaks through 200. The success rate of the first 100 times is 93%. The success rate of the later 100 times exceeds 98% The new-generation rockets are emerging according to the guideline of generalization, seriation and modularization. The developing series cover large middle and small rockets, including CZ5,CZ6, CZ7 which is a newgeneration liquid rocket, and CZ11 which is a solid rocket. 3

4 (1)Mission of CASC Extend space activities to much deeper out space The cosmic space is the future of humanity. Every development of space activities concerns our future. CE-3 reentry vehicles flyby Translunar Libration Point Spaced-Images of Toutatis taken by CE-2 4
