欧洲空间局7月22日宣布,阿里亚娜—5火箭6月4日首次发射失败是由于火箭导航的电脑软件系统发生故障造成的。火箭上当时配置的导航定位软件系统本来是专门为阿里亚娜—4火箭设计的,而阿里亚娜—5的速率提升所需时间要远小于阿里亚娜—4,所以导致原来的软件承受能力出现故障。 一、欧洲航天的黑色星期二 6月4日是令全球航天界兴奋的一天,因为经过上万人10余年的努力,耗资高达70亿美元的欧洲空间局新一代大型运载火箭阿里亚娜—5就要在这天首次升空了。为了这一天的到来,多少人尽心竭力,忘我拼搏,甚至献出了宝贵的生命(去年在试验该火箭主发动机时曾造成两名军官死亡);由于技术复杂,使
The European Space Agency announced on July 22 that the failure of the first launch of the Ariane -5 rocket on June 4 was due to a failure of the rocket navigation computer software system. Rocket was configured navigation software system was originally designed specifically for the Ariane-4 rocket design, and Ariana-5 rate increase is much less time than the Ariane-4, resulting in the original software affordability error occured. I. European Space Day Black Tuesday June 4 is a day that excites the global space community because after more than 10 years of efforts by tens of thousands of people, the new large-scale launch vehicle Ariane-5, a new generation of the European Space Agency costing as much as 7 billion U.S. dollars It is the first time to take off on this day. To this day, how many people dedicated themselves, selfless struggle, and even sacrificed their precious life (last year in the trial of the rocket main engines had resulted in the death of two officers); due to technical complexity, so that
