China Shoots Down Another Satellite
An anonymous reader writes "It was reported this weekend that China shot down another of its satellites in January this year. 'The website of Hong Kong-based Phoenix TV said the anti-satellite missile test, if confirmed, is likely related to the missile interception test, which occurred at the peak of a dispute between Beijing and Washington on a massive US arms sales deal to Taiwan. During the interception test, US agencies spotted two missiles launched from two locations from the Chinese mainland, colliding outside the atmosphere, a Pentagon spokesperson said.' I guess ballistic trajectories that intersect with orbital ones don't count as 'weapons in space.'"
This is part of developing the technology to take out GPS and other communication satellites in case of a confrontation with the U.S.A. . Much of the U.S. war fighting capability is highly dependent on GPS and satellite based communication. The Chinese military is preparing to fight a war against the U.S. (this is completely independent of whether or not they are planning to fight such a war). The scary part of this is that even if current planners have no intention of ever fighting a war against the U.S. history has shown that when military and political leaders believe that they are in a position to win such a war they often choose to wage it even if a rational analysis says that it is a bad idea (see World War I).

Actually I believe that this test didn't contribute to that.
It sounds as if the intercept was at sub orbital speeds. IE it was a missile interception test.
Frankly this was miss titled big time.
Not that it is a good thing but it may not be as bad as you think.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
The story, on a Chinese website (.cn domain) is reporting that the US is reporting that China shot down the satellite. I'm not sure how reliable any of this really is.
The article is unclear, but it sounds more like China tested their ASAT weapon against a launched suborbital target, not an actual satellite as the headline suggests.
A fast ballistic trajectory that either immediately returns to earth, or returns after a couple of orbits, would be a comparatively responsible way of testing these weapons. A well designed test would have most of the same challenges as firing on an actual satellite, without leaving a semi-permanent debris cloud.
Apparently people have completely missed the point of this article. Space junk, yes it's a problem, but did no one grasp the importance that one nation is capable of SHOOTING DOWN SATELLITES?!?
It's obviously aimed at countering US ballistic missile technology that we're selling to Taiwan. Perhaps not to intercept the missiles, but to destroy US GPS satellites so the US missiles won't track. This is just as important as ballistic missile interception program. There's going to be another arms race to have satellites that can "counter" incoming missiles and missiles that can counter the counter on the satellite.
Lastly, can we please stop arming other countries. It always backfires and we end up getting shot by the same bullets we gave out.
