据报道,欧洲新一代运载火箭阿里安-6在法属圭亚那的新发射台选址确定后,法国空间研究中心(CNES)期望该型火箭能在今年7月进入“设计冻结”阶段。阿里安-6是欧洲为将来更好地适应迅速发展的商业发射市场,同时为欧洲政府提供更优的卫星发射服务而研制的新型低成本运载火箭。尽管阿里安-5运载火箭占据了全球发射市场的50%,但政府每年仍需拨付1.2亿欧元才能使其收支平衡。另外,欧洲已经受到美国太空探索技术公司(SpaceX)低成本发射服务,以及中国、俄罗斯、印度等国研制低成本运载火箭的严重威胁。阿里安-6运载火箭的研制费
According to reports, the CNES hopes the rocket will enter the “design freeze” phase in July this year after it confirmed the location of the new European launch pad Ariane-6 at the new launch pad in French Guiana. Arian-6 is a new low-cost launch vehicle that Europe has developed to better adapt to the rapidly growing commercial launch market in the future, while providing European governments with better satellite launch services. Although the Ariane-5 launch vehicle accounts for 50% of the global launch market, the government still needs to allocate 120 million euros a year to balance its revenues and expenditures. In addition, Europe has been hit by low-cost launch services from SpaceX and a serious threat to the development of low-cost launch vehicles in countries such as China, Russia and India.
