1957年10月4日,苏联成功地发射了第一颗人造地球卫星,揭开了人类探索外层空问活动的序幕。30年来,随着科学技术的进步,人类发射的卫星数量及其种类越来越多,如气象卫星、导航卫星、通讯卫星、资源卫星、侦察卫星等等。其间卫星发射开始进入商业市场。但是卫星发射是一个十分复杂的、科学技术性极强的过程,稍有不慎便会导致整个发射计划的失败,造成人力、物力方面的极大损失。如今年5月,美国发射的一颗价值5750万美元的气象卫星,由火箭升空不久熄火,不得不忍痛摧毁,昂贵的卫星连同价值4200万 On October 4, 1957, the Soviet Union successfully launched its first man-made earth satellite, opening the curtain on man’s exploration of outer space activities. Over the past 30 years, with the advancement of science and technology, the number and types of satellites launched by mankind have been increasing, such as meteorological satellites, navigation satellites, communications satellites, resource satellites, reconnaissance satellites, and the like. During the satellite launch began to enter the commercial market. However, satellite launch is a very complicated and highly scientifically technical process. Slight carelessness will lead to the failure of the entire launch plan, resulting in enormous human and material losses. In May of this year, for example, a US $ 57.5 million meteorological satellite launched by the United States shortly after it was off-roading and had to reluctantly destroy it. Expensive satellites, together with a value of 42 million
