中国用新型重型火箭发射新设计的载人飞船
由于使用新型重型火箭发射了一艘新一代载人飞船，中国载人航天计划又向前迈出了一步。
China’s manned space program has token another step forward by launching a new generation manned spaceship with a new type of heavy rocket.
周二，北京时间下午18时（格林尼治时间10时），长征5B火箭在文昌航天发射场发射升空。
The Long March-5B rocket was launched on Tuesday at 6 p.m. BJT(10:00 UTC) from the Wenchang Space Launch Site.

| (火箭)芯级 | stage |
| 由…组成 | consist of .. |
| 3.35米直径 | 3.35-meter-diameter |
| 助推器 | booster |
| 固定在…上 | attach to sth |
长征5 与 长征5B 之间最大的不同是 长征5B 芯级只有“一级半”。
The biggest difference between LM-5 and 5B is that 5B only has one and a half stages compared to two of the LM-5.
“半级”芯级是由固定在芯一级的4个直径3.35米的助推器组成的。
The “half stage” consists of four 3.35-meter-diameter boosters attached to the core stage.

接近54米高 |
nearly 54 meters in height |
18层楼 |
18-story building |
| 点火/点燃 | ignite |
| 再操纵、再调控 | re-maneuver |
| 所有的所有都必须完美 | Everything has to be perfect. |
在修改完成后，长征5B 比长征5 矮3米，轻20吨。火箭接近54米高，与18层楼高相当。
With the modification applied, the 5B became three meters shorter and about 20 tons lighter than the LM-5. The rocket is nearly 54 meters in height, about the size of the 18-story building.
由于缺少了第二个芯级，它只能一次点火，在发射后无法对其进行重新变轨调控，因此要发射到正确的轨道高度变得更困难了。发射的一切工作都必须恰到好处的。
The lack of additional stages makes it harder to be launched to the correct height. Since it can only be ignited once, there’s no way to re-maneuver it after the initial launch. Everything has to be perfect.

火箭的发动机也是新型号。芯一级安装了两个YF-77氢氧发动机，四个助推器各安装了两台YF-100液氧煤油发动机。
The engines of the rocket are also new models. Two YF-77 hydrogen oxygen engines were installed in the core stage, and two YF-100 kerosene and liquid oxygen engines were installed for each of the four boosters.
What is a heavy rocket?

| 更大的(运载)能力 | larger capacity |
| (有效)载荷 | payload |
| 普通(尺寸的)小汽车 | average-sized car |
重型火箭由于更大的载荷而不同于普通火箭。重型火箭能运送超过20吨的有效载荷，比如卫星、探测器、飞船。其运载能力大于10辆普通小汽车。
Heavy rockets are different from normal rockets due to their larger capacity. A heavy rocket can carry more than 20 tons of payloads, like satellites, probes and spaceships. The capacity is larger than 10 average-sized cars.

近地轨道 |
low-earth orbit |
| 世界各地 | around the world |
| 航天局 | space agency |
在长征系列火箭中，长征5B火箭具有最大的助推力。一次发射任务可向近地轨道发送不少于22吨的有效载荷。它主要用于地球附近的200~400公里轨道。
The LM-5B rocket has the biggest boost power in the Long March series. It can deliver no less than 22 tons of payload at a time to low-earth orbits(LEO). It’s main focus will be a 200 to 400 kilometer orbit near Earth.
世界各地的火箭制造商也在建造重型火箭，包括SpaceX公司的重型猎鹰，欧洲航天局的 阿丽亚娜系列火箭，等等。
Other rocket makers around the world also build heavy rockets, including the Falcon Heavy from SpaceX, the Ariane series from European Space Agency (ESA) and many more.

| (进行)多次变轨 | making multiple orbit maneuvers |
飞船模型长9米，可容纳多达7名宇航员。但在本次任务中，由于只是测试所以未搭载任何乘员。
The model is nine meters long and can hold as many as seven astronauts. But in this mission, it carries no one since it’s only a test.
飞船将在太空停留两天，并自动进行多次变轨。
The ship will stay in space for two days making multiple automatic orbit maneuvers.

而且，由于其模块化设计，这艘飞船可重复使用。热保护涂层在再入大气层被烧尽后可再次涂装。
What’s more, the new ship is reusable thanks to its modular design. The thermal-protective coating can be reapplied after being burned-out during re-entry.
