Russian Satellite Hit by Debris from Chinese Anti-Satellite Test [space.com]

Space.com story

So I feel like we're past the point where we can be passive about the problem and expect spacejunk to be negligible and avoidable.
Either PLA wanted to make space access harder for everyone once it secured manned spaceflight, or they have bigger egos than brains, or they don't understand sustainability. That graphic with the debris and ISS orbits is pretty freaky (below).

Also the tracking data seems to have large uncertainties or the statistics aren't to be trusted. -It's the 2nd time a mid-low chance of collision actually happened (there were higher probabilities of collision and closer aproaches by other objects each day).

 Also, ISS has manoeuvred as a result of avoiding this exact debris cloud's object.

If you want to learn more on the subject while being entertained, a good starting point is this movie:

This theatre highly recommended. Only criticism I have is that them red-cyan "goggles" make your FOV significantly smaller, making you have to look around a little sometimes. Non-3D shows have the advantage of filling your FOV with planetarium screen goodness, especially if you're at the back =) Also, any student ID is valid (Y)
