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.'"
Does anyone know how much of an issue the debris from these satellites are? From the perspective of collisions in orbit more so than what happens when it lands (I imagine the parts are small enough that reentry will take care of them).
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.
