Can't believe there's no threads here on this here. Seems to me it's a big BIG news story. The debris from this will be all over and a threat to other satellites. The Hubble is said to be very much at risk. Even a tiny fragment could screw it up and NASA is very concerned, is what I heard on TV yesterday.

A crash of satellites was an accident waiting to happen, there are so many out there. With more and more going up and many just left out there indefinitely it seems like a problem that will get worse and worse. Is it possible that orbiting satellites become too risky at some point, at least for some of them? They've become very important, at least for weather reporting. The surveillance satellites can maybe be dispensed with.

jusr stop it! This is something NASA knew was going to happen, It is not serious at all!
It might be seriosu if you were a 3rd grader and did not understand anything at all!!

Knowing something is going to happen doesn't always prevent bad things from happening. Don't be naive. If you can't take the trouble to proofread your knee jerk reaction posts, why the hell should I take you seriously?

Because you are what is called an alarmist!! Over reactioning to things that mean didly!!

Oh come come. I'm not Chicken Little. I just started a thread in P&N that I think can use a hashing out here. Sheesh. It's a problem that's been getting worse and worse and it seems it's apt to continue to worsen in the future. It bears discussion. It may be "didly" in your world... you're welcome to get your jollies or whatever rocks your boat elsewhere.

I'm not inclined to think that the Hubble itself is in that much of a risky envirnoment, I would think that the risk
would be more likely to the transport vehicle that has to go above and return from where the satellite collision took place.

There would be a crossing of paths risk in each direction through a continuously evolving debris field that contains
tremendous amounts of FOD, twisting and turning, tumbling through space at velocities near or above 17,000 MPH.

If you're traveling in a direction that matches the material trajectory it could be somewhat reduced
possibly to where it would mearly be disasterous instead of catastrophic.
It could be anything - anywhere between a resistor or capacity impacting at 1,000 MPH up to a 5 pound or more transformer
or attitude thruster nozzle bombing in at nearly 35,000 MPH - right through the meteorite shielding and venting the cabin.
(or space suit)

Once going up . . .

and again coming down.

You have no idea how hard it is to do that. A country would need a fairly advanced space program at least on par with China (they have done space walks and launch satellites, and done a direct impact satellite to satellite before) to build, launch and control a satellite to get a direct impact on another. NK or Iran won't be doing this any time soon.

Also people seem to ignore the fact that the debris is a expanding cloud probably in a high density altitude. At the speeds involved in orbiting objects a pebble size chuck of metal will destroy any satellite it hits. I would also imagine that there where many small pieces made in the collision of the satellites.

One bit of good news is that shortly there should be projections on how big the cloud will expand and what it's orbital path will be so it can be avoided, if satellites in its path can move.
