Space Junk

A piece of space junk is moving to within a mile or so of the International Space Station.
Looking at these, it's hardly a wonder.

These are pretty similar to the one's I saw on CNN a few moments ago.

Anyone that has ever been on a big ship, or plane knows that's pretty close.




"A schematic showing the locations of known debris in Earth orbit. Note the heavy concentrations in low-Earth orbit and geostationary orbit"



another illustration




I smell a niche...just not sure what.

LOL

      Freakin crazy huh?

      When I saw the illustration on the news I had to go find an image on the net.

      I knew there were a few satellites, but nothing like this.

        This is really an amazing picture... This seems to be so much...

        There must be something wrong with the scale, according to this image everyone should be able to see a satellite above his house.

        edit: Before you think I'm dumb because everyone could have satellite TV, I meant with the bare eye.

          Actually, if you can get away from city/town lights and watch for awhile you CAN see stuff floating by now and again.

          I also think so.

      It's still so hard to believe... But somehow it makes sense... We need a lot of satellites for GPS, data...

      I'm amazed!

    How do space shuttles manage to get through all that without getting hit?

      One of the tests for our pilots is to drive in rush-hour LA traffic for a week straight...

      Makes dodging a little space junk seem like a cake walk...

        The reason space shuttles and satellites rarely get hit, is exactly that.

        Like the LA freeways, everybody is driving in the same direction.

        You are in very littler danger from the car in the next lane doing 70 if you are also doing 70 in the same direction.

        Same for shuttles and space junk, so long as they are doing 18,000 mph in the same direction they seldom hit each other and their relative speed is very low.

        The new people never mention this, because it de-sensationalizes their story.

        Now....If one were traveling east at 18,000 MPH (standard orbital velocity) and the other were traveling west at 18,000 MPH..........

    Yeah, you really have to wonder. I once heard that MILITARY GPS is accurate to about 3 feet! Commercial GPS has to play a lot of tricks to get as accurate as it is, and it STILL isn't very accurate. Sometimes, when I am at a complicated intersection, the GPS can't see to figure out where I am and, when I turn, it gives me directions for where I WAS! That doesn't happen OFTEN, but I have seen at least 3 intersections where it happens ALL THE TIME!

    Anyway, I imagine there would have to be a lot of satellites. And they need some for communications, and spying. Then there is the debris from all the aircraft, natural phenomena, etc... That FIRST picture shows debris that I figure is maybe 24000 miles away from the earth. I DOUBT we have satellites that far out, and I doubt we have much waste that went that far out, so that is probably natural debris that would have been there with NO space program. It is just in a very high orbit.

    MAN, it looks like there is a transparent version of saturn, and the earth is inside of it! I mean you see the rings, the outer shell, etc.... Of course saturn is about three times the diameter of that image which is about three times the diameter of the earth.

    Yeah lots of clutter for sure. I remember when they had the world's fair in New York city. ( Remember "Men in Black?). They had a sculpture I guess you'd call it, of the earth with 3 or 4 rings around it signifying the satellites in orbit at that time. Now look at it!

    But to put it in perspective when you remember you are looking at a 3d rendering in 2d. Kinda gives a misleading illusion. Also when you consider the shear huge volume of the area represented and the size of the space junk there is still a lot of space between the items in general.

    But a mile is very close in this case relatively speaking. When you look at a picture of a far away galaxy like our own milky way, looking at all the billions of stars from our perspective you would think they should be colliding all over the place. In reality they are usually light years apart.

    It's all relatively relative to the relative reality of the relevance of the relativity to reality realistically and relativity speaking about the relative, right?

      Back then, they were looking for BIGGER chunks, and didn't have any real reason to track them. Most parts seen were probably not reported. So it is unfair to compare the two situations.
