据路透社3月8日电,欧洲空间局第一枚新一代运载火箭阿里安-5将于5月15日首次发射。这项计划是9年前开始的,原定去年升空,但因主发动机试验多次失败(去年5月的一次事故造成法属圭亚那发射场的两名军官死亡),直至今年1月6日才通过最后的试验。 按照设计,阿里安-5能把一颗6.8吨的卫星送入倾角5°～12°的地球同步转移轨道,或把总重5.9吨的两颗卫星射到同样的轨道,也可以把总重5.5吨的三颗卫星推到该轨道上。因此称得上是商业火箭家族中的“大腕”。 到2001年,这种火箭的发射能力将再增加一吨,可以同时发射两颗3.5吨重的卫星,可谓前途无量。
According to Reuters, March 8, the first new generation of European Space Agency carrier Arian-5 will be launched on May 15 for the first time. The plan, which started nine years ago, was originally scheduled to be launched last year. However, due to repeated failures of the main engine test (the death of two military officers from the French Guiana launch site in May last year) until January 6 this year Only through the final test. According to the design, Arian-5 can send a 6.8-ton satellite into geosynchronous orbit with an inclination of 5 ° to 12 ° or shoot two satellites with a total weight of 5.9 tons into the same orbit, Three satellites of 5.5 tons are pushed onto the track. So it is the “big name” in the business rocket family. By 2001, the launch capability of such a rocket would increase by another ton, enabling the simultaneous launch of two 3.5-tonne satellites, promising a promising future.
