[科技] 长征七号运载火箭发射成功 (双语)

　　中国最新运载火箭长征七号从海南文昌发射中心成功发射。长征七号运载火箭将主要用于为中国未来空间站运输货物，以及运载卫星和其他航天器。

　　The latest version of China's carrier rocket, the Long March-7, has been successfully launched from the Wenchang launch center in Hainan. Long March-7 is going to be used mostly to transport cargo to China's future space stations, as well as satellites and other spacecraft.

　　6月25日的发射标志着中国建立永久性空间站的关键一步，也是中国载人航天计划三个阶段的最后一个阶段。长征七号运载火箭是运货飞船，将运载中国空间站的大部分部件。长征七号为液体燃料火箭，长53米，重597吨，可以运载重达13.5吨的货物到低空轨道。

　　The launch on June 25th, 2016 marks a key step towards China's plan to eventually operate a permanent space station, which is the final step of China's three-phased manned space program. The Long March-7 rocket has been designed as a cargo spacecraft, and is set to haul most of the components for China's planned space station. The 53-meter, 597-ton, liquid-fueled rocket can carry up to 13.5 tons into low-Earth orbit.

　　文昌卫星发射中心是中国继甘肃的西昌卫星发射中心、四川的酒泉卫星发射中心以及山西的太原卫星发射中心后的第四个卫星发射中心，位于中国的最南端，可以更接近中国卫星的地球静止轨道。文昌卫星发射中心将主要负责未来的空间站任务。

　　The Wenchang Satellite Launch Center is the fourth of its kind in China, after the Jiuquan Satellite Launch Center in Gansu, the Xichang Satellite Launch Center in Sichuan and the Taiyuan Satellite Launch Center in Shanxi. Located on China's southernmost point, the Wenchang center allows better access to geostationary orbit for Chinese satellites. It will be the main launch site for most future space station missions.
