Do old satellites fall from space?
Yes old sadellites do fall from space but they can't fall back down to earth because the atmosphere is in the way so they will just float back into space into nowhere really. so if you were worried don't worry.

Old satellites that are in orbit and still powered continue to perform their function. Old satellites that have no power and are still in orbit have no use. Those that fall from orbit have no use as the are destroyed on reentry. Old satellites that have never been launched could be used as museum exhibits.
Yes. Collisions between satellites and "space junk" are relatively rare, but as more and more things are sent up, there will be more and more collisions, which will lead to more and more "space junk". Two satellites collided in orbit in the fall of 2008, scattering a couple of tons of space shrapnel through the same orbits that the Space Shuttles and ISS occupy. Pretty soon, we're going to need to set up some sort…
Scientists are still exploring exactly what can be done in outer space and how we can do it, so mostly the space shuttles and space stations have been used for research about weightlessness, vacuum, and other aspects of being in outer space. Space certainly has some very solid practical applications already, such as communications satellites and global positioning satellites, and one of the functions of space shuttles has been to put satellites in their orbits…
Objects in near-Earth orbits will decay over time and fall back into the atmosphere and be destroyed. Objects in higher orbits will remain there until retrieved. There are thousands of pieces of "space junk" cluttering up the orbital area, and sometimes they collide with each other - creating even MORE "space junk".
