近来,美航宇局把航天飞机从火箭总装厂移送到39B 发射台时,对施加于航天飞机上的力进行了测量,目的是验证“挑战者”号发生事故原因的可能性。测量用的是“阿特兰蒂斯”航天飞机,是在对耐气候系统装置试验时一并实施的。到目前为止,39B 发射台与以前使用的39A 不同,从总装厂到发射 Recently, when NASA transferred its space shuttle from the rocket assembly plant to 39B launch pad, the force applied to the space shuttle was measured in order to verify the possibility of an accident on the Challenger. The measurement was made of the Atlantis space shuttle, which was implemented together with the weather-proofing system. So far, the 39B launch pad is different from the 39A used previously, from the assembly plant to the launch
