The China Manned Space Agency said the flight of the carrier rocket Long March-5B successfully verified the overall design and technologies of the new rocket and also marked the beginning of the third stage in China's manned space program which aims to put a manned space station into orbit.

中国载人航天工程办公室表示,长征五号B运载火箭首飞成功,验证了新型火箭的总体设计和技术,同时也标志着我国载人航天工程第三阶段——空间站在轨建造——拉开序幕。

知识点

1992年,党中央作出实施载人航天工程“三步走”发展战略(three-step manned space program):

第一步,发射载人飞船(manned spaceship),建成初步配套的试验性载人飞船工程,开展空间应用实验。

第二步,突破航天员出舱活动技术(extra-vehicular activity)、空间飞行器的交会对接技术(rendezvous and docking),发射空间实验室(space lab),解决有一定规模的、短期有人照料的空间应用问题。

第三步,建造空间站,解决有较大规模的、长期有人照料的空间应用问题(operate a permanent manned space station)。

按计划,我国空间站将于2022年前后完成建造,一共规划12次飞行任务。

After the maiden flight of the Long March-5B the core module of the space station named Tianhe and two experiment capsules named Wentian and Mengtian will be sent into space.

此次任务后,将先后发射天和核心舱、问天实验舱和梦天实验舱。

During the construction of the space station China plans to launch four Shenzhou manned spaceships and four Tianzhou cargo spacecraft to transport astronauts and supplement materials.

其间,规划发射4艘神舟载人飞船和4艘天舟货运飞船,进行航天员乘组轮换和货物补给。

The assembly of the station's core module has been completed and the two experiment capsules and the scientific payloads are under development.

目前,我国空间站核心舱已完成正样产品总装,问天实验舱和梦天实验舱正在开展初样研制,空间科学应用载荷已陆续转入正样研制。

The crewmembers to participate in the construction of the space station have been selected and are trained for the missions. China's third batch of reserve astronauts will be selected around July.

执行空间站建造阶段飞行任务的航天员乘组已经选定,正在开展任务训练。我国第三批预备航天员选拔工作也将于今年7月完成。
