发帖数: 42116 | 1 HOW MANY SATELLITES ARE UP THERE?
About 1,100 active satellites, both government and private. Plus there are
about 2,600 ones that no longer work. Russia launched the first satellite,
Sputnik 1, in 1957. The oldest one still in orbit, which is no longer
functioning, was launched in 1958.
60年来人类发射的卫星也就4000棵，一下子要覆盖全球，4425颗。一个火箭发100颗卫
星，还得44次发射呢。基本就是一个礼拜发一次。，除了印度谁也没一个火箭射那么多
。SPACE-X，我怕重复使用了不了那么多次。而且这4425颗还是首批。 |
