欧洲航天部门正努力争取尽快使“阿里安”5的一揽子改进计划得到批准,以便使这一重要的运载工具不致于在与美俄火箭项目抢占发射服务市场的竞争中被甩到后面.通过这些改进将使“阿丽亚娜”5的有效载荷能力提高,同时也能使其用于发射非静地轨道通信卫星.如果这些改进不能尽快落实,这种火箭与美国、俄罗斯和日本一些新型或改进型火箭的竞争能力将受到影响.
The European space agency is working hard to get the package of improvements planned for the “Arian” 5 approved as soon as possible so that this important means of delivery will not be left behind in the race to seize the launching services market with the U.S.-Russian rocket programs. Improvements will increase the payload capacity of the Ariane 5 and will also allow it to be used to launch non-geostationary orbit communications satellites, and if these improvements can not be implemented expeditiously, such rockets may be as new as the United States, Russia and Japan Improved rocket competitiveness will be affected.
