When testing different diameter pipeline or vessel, the orbit module is changed only.
检测不同管径的管道时，仅需更换轨道模块。
Since the orbiter, the Command Module, had already been thoroughly tested, a decision was made in August 1968 to send Apollo 8 into lunar orbit instead.
由于轨道舱和指令舱已经全部测试完成，于是就决定在1968年8月先把阿波罗8号发送到月球轨道。
The mission was planned as a low-Earth orbit to test the Lunar Module, the lander later used by Apollo 11 and subsequent missions to land on the moon's surface.
他们的使命只是做地球低轨道飞行，以测试月球舱和阿波罗11号以及以后的登月任务所使用的登月舱。
Some reports have indicated that it was in a 4 kilometer by 8 kilometer “orbit” around the module. This is simply not possible within the laws of physics.
一些报道说，这一轨道是围绕轨道舱4到8公里的轨道，这是违反物理定律的。
After the taikonauts had returned to Earth, the BX-1 was placed under active control and commanded to maneuver back towards the orbital module, which had been left in orbit.
宇航员返回地球之后，BX - 1实施了主动控制，并通过命令向留在轨道上的轨道舱返回。
Following a series of maneuvers, the BX-1 was in an orbit where it could observe the SH-7 orbital module and take images from a fairly short distance.
在一系列动作之后，BX - 1处在了离神舟七号不远的轨道上，能观测到神舟七号轨道舱并拍摄照片。
In reality, both the BX-1 and SH-7 module were in almost exactly the same orbit around the Earth, with a slight difference in eccentricity.
实际上，无论BX - 1还是神舟七号都处在几乎一样的绕地轨道上，只有离心率稍稍不同。
From the point of view of the SH-7 module, this resulted in the BX-1 appearing to orbit around the module with between four and eight kilometers of separation.
从神七来看，这点不同造成了BX - 1出现在轨道舱4到8公里距离的轨道上。
It was designed to be tested in low Earth orbit so scientists could see various techniques for separation, rendezvous, and dock with the command and service module.
它被设计为在低地球轨道进行测试，以便科学家可以看到分离，聚集各种技术，并与指挥和服务舱对接。
The coupling relationship and associated effect among orbit design, satellite design and launch determination in the satellite system design were analyzed, and the simplified MDO module was founded.
分析了卫星总体设计中轨道设计、卫星设计和发射选择间的耦合关系与协同效应，建立了MDO的简化模型。
Armstrong and fellow astronaut Buzz Aldrin left the Apollo 11 command module (piloted by Michael Collins) in orbit and performed a landing in the lunar module Eagle.
阿姆斯特朗和同行的宇航员巴兹·奥尔德林(Buzz Aldrin)离开沿轨道运行的阿波罗11号指挥舱(由迈克·科林斯驾驶)，并乘坐“鹰”号登月舱实施了着陆。
Based on the summarization of the orbit design methods, a wizard designer making use of module method was designed in this paper.
文中在对航天器轨道设计方法归纳总结的基础上，采用组件方式设计了向导式轨道设计器。
Lei I said that China plans to launch the experimental core module 2 of its space station around 2018, and the 20 ton combination space station will be sent into orbit around 2022.
雷凡培称，我国计划在2018年前后发射空间站试验性核心舱，2022年前后发射20吨级的组合式空间站。
Then, once the vehicle had ascended to high-Earth orbit, above about 800 kilometers, the nuclear reactor module would detach from the chemical rocket and start up.
这样，当普通燃料火箭到达地球轨道约800公里高度时，核反应堆舱会脱离化学燃料火箭，并开始工作。
The orbital module will continue to orbit the earth and carry out more experiments until its battery runs out.
卫星留轨舱在电池耗尽之前，还将在轨运行一段时间，继续进行一些科学实验任务。
