TWO communications satellites have collided in the first-ever crash of two intact spacecraft in orbit.
The collision occurred yesterday about 800 kilometres over Siberia, The Associated Press (AP) reported.
The crash produced a pair of massive debris clouds, and the magnitude of the situation won't be known for weeks at least, said NASA spokesman Kelly Humphries told AP.

That picture just reinforces what i said on the other thread about this.
"I wonder if our planet is a big cosmic joke, kind of like that redneck uncle with an old impala on blocks in the front yard, and a couple mangy dogs and dirty kids eating from the same bowl. We could be the backwater jerks of the galaxy for all we know, throwing our trash wherever."
We are the hillbillies of the universe.

It would be ironic if Iran's new satellite triggered this. Who knows, after what China did, there may be other ways of taking out satellites by hacking into them etc. Don't these have some type of fuel or similar power source also?

Hmm, i wonder if one of them would have been the new iranian one.....just nudged a bit by the US to set them back a few years.

I suppose this is going to happen, however given the size of space, even with the large number of satellites the probability must be small.
The debris however could be another matter and true hazard, tiny bullet size pieces orbiting at km/sec. Not good.

To put more detail onto this. Nearly all satellites orbit from West to East and in a circular orbit. So most satellites orbiting at a certain altitude will have roughly similar speeds and going the same direction.
No one should expect a head-on collision with a combined speed of over a dozen km/s. Collision speeds will be a fraction of their orbital speed but still significant.
