美航宇局在分析了4月6日在肯尼迪航天中心的39B发射台上对原发动机进行26s飞行状态试车之后,决定要在最新的奋进号航天飞机上更换全部三台主发动机。发动机所暴露出的一些小问题被认为超出安全临界值,美航宇局认为更换全部三台主发动机比修复方案更容易.这组发动机原计划用于阿特兰蒂斯号的下次飞行。奋进号航天飞机的首次发射的安排在5月初进行,这次飞行的任务是救援一颗国际通信卫星组织的Intelsat-6通信卫星.在发射前将不再进行飞行状态试车。阿特兰蒂斯号航天飞机于4月2日第九次在肯尼迪航天中心着陆。在这之前。它非常成功地飞行
After analyzing the 26s flight test of the original engine on the 39B launch pad of the Kennedy Space Center on April 6, NASA decided to replace all three main engines on the latest space shuttle Endeavor. Some minor problems exposed by the engine are considered to exceed safety thresholds, and NASA believes it is easier to replace all three main engines than the remediation program originally planned for the next Atlantis flight. The first launch of the space shuttle Endeavor took place in early May and is tasked with rescue of Intelsat-6, an Intelsat-6 satellite, that will no longer be in flight prior to launch. The Atlantis space shuttle landed at the Kennedy Space Center for the ninth time on April 2. before this. It flies very successfully
