欧洲的阿里安火箭于9月10日从库鲁发射场首次作商业性发射,准备同时把欧洲“海事通信卫星-B”和一颗气象卫星“西里奥-2”送入地球同步轨道,但事不随人愿,大约飞行了14分钟后,该火箭连同它所运载的两颗卫星一起葬身于汪洋大海,损失约1.85亿美元。这次失败是由于火箭第三级的燃料泵发生爆炸引起的。按原计划第三级发动机应点火9分30秒,但根据遥测数据表明:燃料泵在4分23秒后突然减慢了向发动机注入
The Armenian rockets in Europe were first commercially launched from the Kuru Launch Center on 10 September in preparation for the simultaneous launch of the European maritime communications satellite-B and the meteorological satellite Cyrio -2 into geosynchronous orbit, After about 14 minutes of flying, the rocket, along with the two satellites it carried, was buried in the open ocean at a loss of about 185 million U.S. dollars. This failure was caused by the explosion of the rocket’s third-stage fuel pump. According to the original plan, the third-stage engine should be ignited for 9 minutes and 30 seconds, but according to the telemetering data, the fuel pump suddenly slowed down to the engine after 4 minutes and 23 seconds
