升空！入轨！成功！
4月29 日11时22分许，执行我国空间站“天和”核心舱任务的长征五号B遥二运载火箭，在中国文昌航天发射场点火发射。
升空后，“天和”核心舱与火箭成功分离，进入预定轨道，之后太阳能帆板两翼顺利展开且工作正常，发射任务取得圆满成功。
中国“天宫”空间站为期两年的建设之路，正式起航。
China on Thursday sent into space the core module of its space station, starting a series of key launch missions that aim to complete the construction of the station by the end of next year.
The launch was done at the country's space station from the Wenchang Space Launch Site in the southern province of Hainan.
The core module, named Tianhe, was carried into space by a Long March-5B Y2 carrier rocket.

升空飞行大约170秒后，一级火箭任务完成，主动脱离舰体，开始由火箭芯级发动机继续推动火箭升空入轨。
升空220秒后，之前一直在整个火箭顶端保护航天器、承受高温摩擦和气压巨变的整流罩，也主动分离。
升空493秒，芯级发动机成功脱离，“天和”核心舱成功进入轨道，控制室里响起欢呼。
“天宫”什么样？
明年，“问天”实验舱和“梦天”实验舱将发射。届时，“天和”核心舱及两个实验舱将组成T型的中国空间站——“天宫”空间站。
“天和”核心舱是中国空间站发射入轨的首个舱段，长16.6米，最大直径4.2米，起飞质量22.5吨，是目前我国自主研制的规模最大、系统最复杂的航天器。
它将被主要用于空间站统一控制和管理，具备长期自主飞行能力，可支持航天员长期驻留，开展航天医学、空间科学实验和技术试验。
Next China will carry out cargo replenishment missions and launch a manned flight for its space station program. The construction of China's space station Tiangong is scheduled to be completed by around 2022.
Tianhe will act as the foundational module for China's first space station in low-Earth orbit named Tiangong, which means "heavenly palace" in Chinese.
The space station will form a T-shape with Tianhe at the center and two lab capsules, Wentian and Mengtian, on each side, according to Zhou Jianping, chief designer of China's manned space program.
The habitable space inside the core module is about 50 cubic meters. When the two lab capsules are in place, the total living space of the whole complex will reach 110 cubic meters, according to Zhou.
The core module has two berth ports that can connect with the two lab capsules and three docking ports for cargo vessel, manned spaceship and other spacecrafts. It also has an exit for astronauts to conduct extravehicular activities.
1/11，完成！
按照规划，2021-2022年，我国将接续实施11次飞行任务，包括3次舱段发射、4次货运飞船以及4次载人飞船发射，于2022年完成空间站在轨建造，实现中国载人航天工程“三步走”发展战略“第三步”的任务目标。
此次发射是11次任务中的第一次。
今年，我国预计还将实施发射神舟十二号、神舟十三号载人飞船，以及天舟二号、天舟三号货运飞船。
剩下的10次发射，也将由长征火箭挑起大梁。
As one of China's most complicated space missions so far, the construction of the space station requires 11 launches in 2021-2022, including Thursday's successful launch of the core module, two more module launches, four crewed missions and four cargo vessel flights.
Three types of Long March carrier rockets will jointly execute the rest of the 10 launch missions.
The Long March-5B rocket will be tasked with transporting the two lab modules, the Long March-7 rocket will launch the cargo spacecraft and the Long March-2F will launch the manned spacecraft into space.
