They don't fall because they're travelling too fast to fall. An orbit is technically a fall. An object orbits when it falls at the same rate as its forward movement, so while it's falling toward the earth, the earth is falling away from it below.
no beacause it wont fall down into the earth
Satellites may fall out of the sky because they get too close to Earth. In that case, Earth overwhelmed the power of the satellite's propelling system and slowly but surely dragged the satellite into the Earth's atmosphere.
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. from abby mcmillan (19) (tel. 0428341687)if you want more info.
Gravity pulls the satellites but the orbiting satellites don't fall down towards earth because the speed with which they move balances the gravitational force i.e. Centripetal force = Gravitational force.
that is because the 0 gravity keeps it in space and the orbit brings them around without knocking them down or anywhere else
Satellites orbit the earth for a few years then fall to earth however they are directed to fall to the sea
. The speed of the satellite is adjusted so that it falls to earth at the same rate that the curve of the earth falls away from the satellite. The satellite is perpetually falling, but it never hits the ground!

Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
about a 100 basket-ball sized satelittes fall every year.
That will depend whether the microscope is designed to cope with the new wavelength as well as it did with the old. For example, ordinary visible-light microscopes are useless for ultraviolet. The absolute limit to resolving power with perfect optics is about quarter of a wavelength but real microscopes fall short of this.

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.

It comes from pieces that fall of satellites or that are blown of satellites when they collide or are blasted by a missile. Some of the space junk is also spent rocket stages.
