DELORES YOUNG, ATLANTA, GEORGIA: Hello, my name is Delores Young, and I am from Atlanta, Georgia. And my question is: how do they keep all the satellites in space without colliding with one another?</s>MILES O'BRIEN, CNN SPACE CORRESPONDENT: Well, let's talk first of all about communications satellites. Way back when when communications satellites first started flying, of course, there wasn't an issue of things bumping into each other, but it wasn't long before all these satellites ended up parked in orbits, relatively close to each other. What happened was the nations of the world, led by the United States, formed the first satellite consortium, called Intelsat, and it basically created a nonprofit organization to operate these communications satellites, and also allocate where they can exist on the horizon. Now we've gotten to the point where there are so many communication satellites up there that space is at a premium. As a matter of fact, in order for new satellites to be launched, typically speaking, an old one has to be taken out of service. So, this is a bit of a problem, except when you consider the fact that other technologies, for instance, fiber-optic cable, are making the need for those communication satellites diminished. So while space may be at a premium, way up there 22,300 miles above us, it may not be a problem.
