中国航天科技集团公司上周六表示，一枚长征五号运载火箭已运抵海南文昌，为计划于6月进行的实践十八号通信卫星发射任务做准备。
It will be the second mission of the Long March-5 which made its maiden flight from Wenchang in November.这将是长征五号继去年十一月的文昌首飞后的第二项任务。During the mission, the rocket will further test its core technology, accumulate data and provide support ahead of the launch of the Chang'e-5 lunar probe in the second part of this year.
执行此次任务过程中，长征五号将进一步测试其关键技术，积累数据，为今年下半年执行嫦娥五号月球探测器发射任务提供支持。Fuelled by liquid hydrogen, kerosene and liquid oxygen, the Long March-5 can carry a payload of 25 tons into low Earth orbit and 14 tons in geostationary transfer orbit, over 2.5 times the capacity of other models of Long March carrier rockets.长征五号以液氢、煤油、液氧为燃料，近地轨道运载能力达到25吨级，地球同步转移轨道运载能力达到14吨级，是其他型号长征系列运载火箭的运载能力的2.5倍以上。
