天舟四號貨運(yùn)飛船成功發(fā)射

China launched the Tianzhou-4 cargo spacecraft on Tuesday to deliver supplies to its space station, which is scheduled to wrap up construction this year. The Long March-7 Y5 rocket carrying Tianzhou-4, blasted off at 1:56 a.m. (Beijing Time) from the Wenchang Spacecraft Launch Site in the southern island province of Hainan, according to the China Manned Space Agency. After around 10 minutes, Tianzhou-4 separated from the rocket and entered its designated orbit. At 2:23 a.m., the solar panels of the cargo craft unfolded and began working. Tianzhou-4 successfully docked with the combined space station core module Tianhe and the Tianzhou-3 cargo craft later on Tuesday. 據(jù)中國載人航天工程辦公室消息，北京時(shí)間5月10日1時(shí)56分，搭載天舟四號貨運(yùn)飛船的長征七號遙五運(yùn)載火箭，在我國文昌航天發(fā)射場點(diǎn)火發(fā)射，約10分鐘后，飛船與火箭成功分離，進(jìn)入預(yù)定軌道，2時(shí)23分，飛船太陽能帆板順利展開工作，發(fā)射取得圓滿成功。在歷經(jīng)數(shù)小時(shí)的飛行后，天舟四號順利"牽手"空間站天和核心艙與天舟三號組合體。根據(jù)計(jì)劃，中國空間站將于今年完成在軌建造，此次天舟四號的任務(wù)是向空間站運(yùn)輸物資。
