| Abstract: | Space launch successes and failures data in the whole world in the past fifty years(from 1957 to 2006) is collected.Each space-faring nation's launch success rate as a percentage of its total launches are given.Space launch vehicle reliability for U.S.and China is particularly presented.An analysis of space-mission failures and cause of failures is introduced.Launch vehicle failures are classified by subsystem.For propulsion subsystem problems predominated,some preventive measures are put forward.Finally,the proposal of the development work for enhancing reliability is given. |

| Keywords: | space launch vehicle reliability failure cause propulsion subsystem preventive measure |
