1·International space Station in near Earth orbit, NASA astronauts carried out space walks and lost a bolt and a watcher.

在国际空间站接近地球轨道的地方，NASA的宇航员完成了太空行走，迷失了一个螺钉和一个观测仪。

2·The experiment is conducted in co-axial atomic oxygen apparatus under the atomic oxygen flux of near earth orbit environment.

实验中采用同轴源原子氧装置，以近地轨道原子氧通量条件对涂层进行试验。

3·For instance, Earth 2 can be seen hanging in the sky near Polaris, the north star, which would put its orbit perpendicular to the solar system's ecliptic-and ripe for discovery long ago.

举例来说，地球2可以在接近北极星的天空中被看到，就是说它的轨道垂直于太阳系黄道，早就准备着被发现了。

4·For instance, Earth 2 can be seen hanging in the sky near Polaris, the north star, which would put its orbit perpendicular to the solar system’s ecliptic—and ripe for discovery long ago.

举例来说，地球2可以在接近北极星的天空中被看到，就是说它的轨道垂直于太阳系黄道，早就准备着被发现了。

5·If we take the shuttle as an example of a near-Earth orbit, so we have the shuttle.

我们以航天飞机为例，在近地球轨道上，有一个航天飞机。

6·If you are near Earth in orbit, you are eight kilometers per second, and eight times the square root of two 2 is exactly that 11.2.

如果你在轨道接近，地球，那是8千米每秒，8乘以2平方根，正好是11。

7·Those are hardly the only asteroids of that size out there, but they're the ones that also qualify as near Earth - which means they cross or approach our orbit around the sun.

那些还不是那里全部的那么大的小行星，但他们也可称作近地小行星- - - - - -意思是他们的轨道与我们绕太阳的轨道交叉或很接近。

8·The observation problem for a very wide field of view is solved in the orbit for near earth.

设计了一种三轴紫外敏感器，解决了近地轨道大视场观测问题。

9·The traditional thermal environment parameters for near-earth orbit are compared with those currently adopted by international spacecraft thermal design community.

介绍了目前国际上普遍采用的近地轨道热环境参数与传统参数之间的差异。

10·This means that the Earth moves faster along the orbit in winter near perihelion.

这意味着地球在靠近冬至点附近的冬季运行得较快。
