本文汇编了1960～1980年期间发射的、戈达德空间飞行中心主管的104颗卫星(搭载卫星和不是该中心主要负责的卫星除外)的数据。根据卫星头三年轨道运行的统计分析表明:1960～1964年卫星处于幼年时期,这时宇航工业也处于幼年时期,卫星中等寿命只有0.5年;1965～1969年卫星中等寿命已超过1年,但尚未完全摆脱早期失效问题,发射后2～5年星上元部件陆续损坏,损坏的主要元部件有蓄电池、磁带记录器、太阳帆板驱动装置和扫描装置等;1970～1974年,卫星故障表现为“随机性”,1年设计寿命已成为保守设计了;到了七十年代后期,实际寿命远远超过设计寿命,戈达德
This article compiles data on 104 satellites (excluding satellites that are not primarily responsible for satellites) that were launched by the Goddard Space Flight Center during the period 1960-1980. According to the first three years of satellite orbital operation of the statistical analysis showed that: from 1960 to 1964 satellite at an early age, when the aerospace industry is also in its infancy, satellite medium life is only 0.5 years; satellite 1965-1969 medium life expectancy has more than 1 year, Not completely get rid of the problem of early failure, after the launch of 2 to 5 years on the satellite components gradually damaged, the main components of damage have batteries, tape recorders, solar panels drive and scanning devices; 1970 ~ 1974, the satellite failure performance As a “random”, 1 year design life has become a conservative design; to the late seventies, the actual life expectancy far beyond the design life, Goddard
