15、Just half a dozen holiday-makers have reachedorbit since then, for similarly astronomical price tags.(从那之后，只有6个度假者到达了太空轨道，价格也同样是天文数字。)
16、Changes in the eccentricity of Earth'sorbit occur in a cycle of about 96,000 years.(地球轨道偏心率的变化大约在96000年的一个周期内发生。)
17、Unlike earlier lunar missions, Clementine didn'torbit only around the moon's equator.(不像早些时候的月球探测那样，克莱门飞船并不是仅仅沿着月球的轨道飞行。)
18、Astronauts will make a final attempt today to rescue a communications satellite from its uselessorbit.(宇航员们今天将做最后一次尝试，把一颗通讯卫星从它无用的轨道上拯救出来。)
19、The government is more focused on preventing new debris from forming than taking the trash out oforbit.(政府更关注的是防止新的碎片形成，而不是把垃圾带离轨道。)
20、As it lost weight, it started to incline itsorbit toward the earth: it was dangerous, above and beyond anything else.(当它失重的时候，它开始将它的轨道向地球倾斜：这是危险的，比其他任何东西都危险。)
21、This kind of periodicorbit is only a phase in a comet's life.(这种周期性轨道只是彗星生命中的一个阶段。)
22、One characteristic of Earth'sorbit is its eccentricity, the degree to which theorbit is an ellipse rather than a circle.(地球轨道的一个特点是它的离心率，也就是轨道是椭圆而不是圆形的程度。)
23、The shape of thisorbit isn't consistent; it varies over time, over a period of about a thousand years.(轨道的形状并不是始终如一的；它会随时间变化，变化周期为一百年左右。)
