manned lunar-landing

on a spacewalk last year, and has announced plans to launch a manned lunar mission and a military space station.

它也成为第三个实现太空行走计划的国家。并且已经宣布计划发射载人登月飞船和建立军事空间站。

The scale of space station for manned lunar-landing mission is conceived. 2. A trans-lunar trajectory model is established, and the constraint conditions are given according to practical situations in engineering.

建立了空间站支持登月的奔月轨道模型，并结合工程实际背景，给出了轨道设计的约束条件。

According to Yu, China is conducting a further verification study for the research and development of a space station and manned lunar mission, and it plans to set up an unmanned lunar research station for manned landings on the moon.

于登云表示，我国正开展空间站研制和载人登月深化论证，还计划建设无人月球科研站，开展载人登月工作。

But the large quantity boosts the case for a manned lunar base from which to launch other interplanetary adventures.

但证明有大量水的存在增加了在月球上建立有人驻守基地的可能性，从基地就可以进行其他星际探险活动。

More than 90% of the mass required for manned Mars and Lunar exploration is propellant.

载人群众超过90%火星和月球探测的推进剂。

In the new century, impressive achievements have been scored in manned spaceflight and lunar probe projects.

进入新世纪, 我们又在载人航天与探月工程领域取得了令世人瞩目的重大进展.
