天上能看到卫星吗－ERBS
本帖最后由 wuliaors 于 2012-5-3 13:42 编辑有时候在看天空，会发现一个小小的亮点在移动，速度比较慢，方向固定，想想是什么呢，可能是飞机，怎么会飞那么高呢？想了很久也没找到答案。今天用一个星图软件starry night，看看今天晚上的星空怎么样，无意间发现一个移到的小亮点，和前几次看到的有些相似，于是点上去看了下详细的信息，软件马上显示出一个名字ERBS，是一颗人造卫星。在晚上20：06分时在天狼星的东侧升起，导出一个数据看看：

有了这个数据就可以在晚上的时候看看啦！
BackgroundThe ERBS satellite was deployed from the Space Shuttle Challenger in October 1984 by NASA Astronaut Sally Ride and later launched by the Shuttle "Challenger" crew into a 57 degree inclination precessing orbit with a period of approximately 72 days. In addition to the ERBE scanning and nonscanning instruments, the satellite also carried the Stratospheric Aerosol Gas Experiment (SAGE II). The ERBS was the first of three ERBE platforms which would eventually carry the ERBE Instruments. The second ERBE Instrument was aboard the NOAA-9 satellite when it was launched in January of 1985, and the third was aboard the NOAA-10 satellite when it was launched in October of 1986. Although the scanning instruments on board all three ERBE satellites have failed, the nonscanning instruments are all presently functioning.
在晴朗的夜晚，用肉眼很容易看到很多人造地球卫星！我曾经在1小时里看到19颗卫星和3颗流星！你如果试一试，说不准比我看到的还要多！ 谢谢啦，:(:(:( 可以看到卫星，小时候见过，现在好像没看到了 从来没看到过 ::070821_07.jpg:: 生活在光污严重的城市里的苦逼表示一个也没看到过。 记得小时候天上最多能同时看到三颗卫星，二颗同时在的都比较常见的。 我在老家目视看到过几次但是我在城里没有看到过，
