中國航天科技集團公司上周六表示，一枚長征五號運載火箭已運抵海南文昌，為計劃于6月進行的實踐十八號通信衛星發射任務做準備。
It will be the second mission of the Long March-5 which made its maiden flight from Wenchang in November.
這將是長征五號繼去年十一月的文昌首飛后的第二項任務。
During the mission, the rocket will further test its core technology, accumulate data andprovide support ahead of the launch of the Chang'e-5 lunar probe in the second part of thisyear.
執行此次任務過程中，長征五號將進一步測試其關鍵技術，積累數據，為今年下半年執行嫦娥五號月球探測器發射任務提供支持。
Fuelled by liquid hydrogen, kerosene and liquid oxygen, the Long March-5 can carry apayload of 25 tons into low Earth orbit and 14 tons in geostationary transfer orbit, over 2.5times the capacity of other models of Long March carrier rockets.
長征五號以液氫、煤油、液氧為燃料，近地軌道運載能力達到25噸級，地球同步轉移軌道運載能力達到14噸級，是其他型號長征系列運載火箭的運載能力的2.5倍以上。
