Air Force Sets First Post In Ambitious Space Fence Project 65
coondoggie writes "The US Air Force this week said it will base the first Space Fence radar post on Kwajalein Island in the Republic of the Marshall Islands with the site planned to be operational by 2017. The Space Fence is part of the Department of Defense's effort to better track and detect space objects which can consist of thousands of pieces of space debris as well as commercial and military satellite parts."

Funny, but false. I've made relevant FPs and had them modded +5 insightful before, and I'm not the only one. And I try to avoid FPs because just being FP can get your comment modded so low that making it was a waste of time, no matter how good a comment it is. If you want to be seen, be the second poster and reply to the "funny" FP with something interesting.

I'm a little bit suspicious. What else can this site track? Will the US be sharing its data with everyone, or will there be many convenient holes in coverage?
Re:What are the military applications? (Score:4, Insightful)
Because Kessler Syndrome. Space debris collisions create more space debris, which in the long term will cause problems for the use of space with everyone. Ideally these things should be dealt with internationally - it doesn't really make sense to have every nation look after their own satellites, and it'd lead to much wasteful duplication of effort.
Re: (Score:3)
The ideal solution would certainly be that everyone would chip in, since it's in everyone's interests. If the US is determined to go it alone anyway and build this thing, though, a far sighted strategist should realise that *even if* no one else offers to pay, it serves long term US interests to actually share this data with as many countries at possible. And maybe such a move would create goodwill and help dispel suspicion, and encourage global support (and funding) for future maintenance of the project.
Re: (Score:1)
So, just to be clear: the best reason for sharing this information with everyone is that maybe they will be grateful and help pay for maintenance? Why on earth would we expect that to work when we've already shown we'll happily pay for it ourselves and share the information? More to the point, why is it better than selling the information at a price that is (slightly) lower than what a country would have to spend to set up and maintain their own equivalent system, which would guarantee funding?

Re: (Score:1)
The reason for sharing this information is that without this information other nations' space programs are more likely to have space collisions which will result in more space junk that will make things harder for us.
And harder for the other nations, too. But not so hard for us since we have a radar that can track space junk. Right?
Re: (Score:2)
Secondary debris from collisions are smaller and more difficult to track.
Re: (Score:2)
You act like no other countries are going to do this on their own. In fact, they already are doing it [wikipedia.org] and have been for some time. And they know the value of sharing what they find, just like the USA does. Knowledge shared is knowledge improved.

Applications are:
1. Track other spy satellites, of the Russians, Indians, Chinese. In the future, I guess that these countries will have hundreds of those - many quite small.
2. Avoid collisions of their own satellites. The US also has hundreds of satellites in orbit.
3. Avoid collisions of other (commercial?) satellites, thereby protecting US economic interests.
In this particular case, I don't care whether they share. Even if they don't share, I am not particularly worried. What flies overhead shouldn't be h

Obviously they're going to track every object of concern that they can. The project makes no sense otherwise.
My guess is that the information will be redacted before it is shared, to remove anything that is strategically sensitive. That includes, for example, information about spy satellites, whether they're "ours" or "theirs."
As for whether this project is intended to track stuff for strategic gain, I'd be surprised if that didn't happen, but I'm not sure that's its primary purpose.

But I did think of another idea.
If you wanted to build a space fence, you would need a very high fence post, going up to 50,000 miles or so. (well it could be shorted but it would have to have a counterweight at the top, so that the center of mass is at 25,000 miles, and it would orbit above a spot on the equator without needing any fuel to keep it there.
You could also call it a 'Clarke Tower' after the guy who wrote about it.
