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.

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，爲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 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.
