——开放发展。坚持独立自主与开放合作相结合，在平等互利、和平利用、包容发展基础上，积极开展航天国际交流与合作，致力于推进人类航天事业的共同进步和长期可持续发展。

　　二、2011年以来的主要进展

　　2011年以来，中国航天事业持续快速发展，自主创新能力显著增强，进入空间能力大幅提升，空间基础设施不断完善，载人航天、月球探测、北斗卫星导航系统、高分辨率对地观测系统等重大工程建设顺利推进，空间科学、空间技术、空间应用取得丰硕成果。

- Open development. China persists in combining independence and self-reliance with opening to the outside world and international cooperation. It actively engages in international exchanges and cooperation on the basis of equality and mutual benefit, peaceful utilization, and inclusive development, striving to promote progress of space industry for mankind as a whole and its long-term sustainable development.

II. Major Developments Since 2011

Since 2011 China's space industry has witnessed rapid progress manifested by markedly enhanced capacity in independent innovation and access to outer space, constant improvement in space infrastructure, smooth implementation of major projects such as manned spaceflight, lunar exploration, the Beidou Navigation System and high-resolution earth observation system, and substantial achievements in space science, technology and applications.

　　（一）航天运输系统

　　2011年以来，截至2016年11月，长征系列运载火箭共完成86次发射任务，将100多个航天器成功送入预定轨道，发射成功率达到97.67%，运载火箭的可靠性和高密度发射能力持续增强。中国最大运载能力新一代运载火箭“长征五号”成功首飞，实现中国液体运载火箭直径从3.35米到5米的跨越，大幅提升“长征”系列运载火箭运载能力，低轨运载能力达到25吨级，高轨运载能力达到14吨级，成为中国运载火箭升级换代的重要标志。120吨级液氧煤油发动机完成研制，应用该型发动机的“长征六号”“长征七号”新型运载火箭实现首飞，“长征十一号”固体运载火箭成功发射，运载火箭型谱进一步完善。

　　（二）人造地球卫星

1.Space transportation system

From 2011 to November 2016 the Long March carrier rocket series completed 86 launch missions, sending over 100 spacecraft into target orbit with a success rate of 97.67 percent, indication of increasing effectiveness and high-density launching capability of carrier rockets. The Long March 5 (CZ-5), China's newest generation of carrier rockets with a maximum carrying capacity, made its maiden flight, and increased the diameter of liquid fuel rocket from 3.35 m to 5 m, with a maximum payload capacity of about 25 tons to low earth orbit and about 14 tons to geostationary transfer orbit, significantly improving the carrying capacity of the Long March rocket family and becoming a symbol of the upgrading of China's carrier rockets. The development of the 120-ton liquid oxygen and kerosene engine was test fired, which powered Long March 6 and Long March 7 on their maiden flights. The Long March 11, a solid-fuel carrier rocket, also made a successful maiden launch, further enriching the Long March rocket family.
