East is red design life has 20 days only, but it worked actually 28 days in aerospace, what make everybody cannot understand most is, it flew 47 years full in the sky actually.
Is the east that does not have fuel so red the where that how accomplishs is one?
Above all the life that what we should understand is a satellite and run time are two different matters. Satellitic life is the functional life that points to him, want be need energy to realize specific function, and the satellite can carry a solar battery commonly board, regard oneself as the origin of energy. But did not carry a solar battery as a result of Oriental Gong Weixing board, so when energy is extinct also lose a function.
But actually the satellite moves on orbit do not need energy. Because,this is satellite around the earth moving is to lean inertial those who maintain, and because leave the appeal of mental efforts and earth mutual,be balanced, fall in the circumstance that does not have wind resistance so, the satellite can wind earthly campaign forever, this is why in 47 years, it can do not have sunset night to become the matter of rotation around the earth.
Why doesn't that call in the satellite?
Actually China has such idea, still just do not have such ability at present, because east is red,flight height is between 430~2075 kilometer, this has exceeded the highest height that American space shuttle can reach, namely 960 kilometers.
Besides, reclaim the satellite is to have very big risk, and east is red already invalidation, the ground can no more the palm accuses its motion contrail, cannot catch it well and truly so, finish a knock off very hard also in aerospace to make.
East is red fall from the sky of a final meeting
Why? Because east is red,one is to blast off actually in low altitude orbital. And Telstar works to maintain its ability, blast off in the earth dormant orbit, can perpendicular square on equator, with earthly synchronism, because be affected by earthly gravitation, east is red a meeting stands by the earth slowly, it is final in aerosphere, as obstruction bigger and bigger, satellitic loss also is met bigger and bigger, melt into cindery or fragment, fall to the earth.
East is red one bore the weight of Chinese spaceflight person's too much memory, if one day it can fall,answer the earth, the debris that I think it can be become to list Chinese aviation museum certainly in, as permanent collect carefully.
