6月25日20时整,我国载人航天工程为发射货运飞船而全新研制的长征七号运载火箭,在海南文昌航天发射场发射成功。6月26日15时41分,由长征七号运载火箭搭载升空的多用途飞船缩比返回舱,在东风着陆场西南戈壁区安全着陆。长征七号运载火箭首飞,是载人航天工程空间实验室飞行任务的开局之战,实现了“成功首飞”的预定目标,为后续任务打下了坚实的基础。这次发射,旨在验证长征七号运载火箭设计正确性和各项性能指标,考核海南文昌航天发射场系统执行任务能力,检验工程相关系统间的协调性和匹配性。同时,长征七号火箭搭载多用途飞船缩比返回舱等载荷,将开展相关技术试验。这是长征系列运载火箭的第230次飞行。
At 20:00 on June 25, the newly-built Long March VII launch vehicle for launching the cargo spacecraft in China’s manned space project was launched successfully at the Wenchang Space Launch Site in Hainan. At 1541 hours on 26 June, the multi-purpose spacecraft with the launch of the Long March VII rocket was loaded with a reduction ratio return capsule to land safely in the southwestern Gobi area of the Dongfeng Landing Field. The first flight of the Long March VII launch vehicle was the opening battle for the space mission of the manned space project and achieved the scheduled goal of “making the first flight successful”, laying a solid foundation for subsequent tasks. The launch aims to verify the design of the Long March VII launch vehicle correctness and various performance indicators to test the ability of the implementation of the mission of Hainan Wenchang space launch site system to test the coordination and matching between systems related to the project. At the same time, the Long March VII rocket equipped with multi-purpose spacecraft reduced return capsule and other loads, will carry out related technical tests. This is the 230th flight of the Long March series carrier rocket.
