人造卫星

The news of snow falling is just one piece of an extraordinary wealth of information that has recently been sent back from Mars by orbiters, landers and rovers.

这只是人造卫星，登陆车，漫游车报告回来的惊人消息中的一条罢了。

The Mars Global Surveyor arrived at the red planet nine years ago. It was the first of several orbiters that are surveying the cold, barren landscape, looking especially for signs of water and relaying signals from the two robotic rovers crawling over the terrain.

火星环球探测者号是9年前被发送到这颗红色行星上的，它是几颗人造卫星中第一个被发送到这个寒冷贫瘠的星球上的，用于探测各种物质特别是水存在的迹象，并通过两个自动机械漫游者把信号传回地球。

Ten years or 100 flights, and though bad weather put paid to that, the five spaceworthy orbiters made morethan 130 flights.

航天与宇航局本打算每个人造卫星能支持10年或进行100次飞行，这五颗卫星共飞行了130多次，只不过坏天气也有一些影响。

新飞船加载了另外两枚美国人造卫星和一枚欧洲卫星一同绕火星运行。

The Mars Global Surveyor arrive d at the red planet 9 years ago. It was the first of several orbiters that are surveying the cold, barren landscape, looking especially for signs of water, and relaying signals from the two robotic rovers crawling over the terrain .

火星环球探测者号于9年前抵达红色行星，它是最早几个被发送去探测这个寒冷并且贫瘠的星球里特别是水的征兆及通过地形与另外两个自动机械漫游者转播信号的人造卫星之一。

这个新飞行器将与另外两个围绕火星飞行的人造卫星和一个欧洲探测器联手。

China's lunar orbiter project has cost 1.4 billion yuan about 133 to 187 million U.S.

China will enable two orbiter, but the time with this many need and money.

中国将启用两颗人造卫星，可是这需要大量的时候和金钱。

Modern and practical astronomy was developed in the 18th century, and successively from the theoretical and practical solution to the Sino-satellite instrument measuring time, too Seoul Scott multi-satellite measurements such as latitude, as well as simultaneous determination of longitude and latitude Supreme Court means the emergence of theodolite, contour instrument, the satellite instrument, zenith instrument, photographic zenith tube, sextant and other useful astronomical instruments, the most commonly used is the optical theodolite .20 century, all-round practical field of astronomy 60 years after the emergence of new technologies, such as satellite Dhoop Le observation and satellite laser ranging, not only the accuracy of more than optical observations, but also greatly improved operating speed, and can provide direct point of geocentric coordinates of the ground.

现代实用天文学是18世纪发展起来的，先后从理论和实践上解决了中星仪测时、太尔各特测纬以及多星等高法同时测定经度和纬度的方法，出现了经纬仪、等高仪、中星仪、天顶仪、照相天顶筒、六分仪等实用天文学仪器，最常用的是光学全能经纬仪。20世纪60年代以后实用天文学领域出现了崭新的技术，如人造卫星多普勒观测和人卫激光测距，不但精度超过光学观测，而且作业速度大大提高，并能直接提供地面点的地心坐标。

Based on readings of light from this artificial star, a six-inch deformable mirror is adjusted as many as 2,000 times a second to eliminate blur.

基于对由这种人造卫星发出的光的认读，一架6英寸的可变位反射镜自动校正每秒多达2000次，以消除失真。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
