How do spacecraft return to Earth?

First they need to slow their speed so the earth's gravity can 'catch' them. This is done by doing a de-orbit burn. The space shuttle then literally falls from the sky - but in a well planned path - to come to an unpowered landing in either Florida at Kennedy Space Center, or at Edwards Airforce Base in California. The commander is in control and so the landing is done manually as there is considerably more risk with a computer controlled one. A parachute slows the shuttle once it has landed. The Russian Soyuz craft literally fall back to earth onto land, slowed by parachutes.

During earlier missions such as Apollo, the capsule came in backwards and a protective shield gradually burnt away thus taking the heat with it. Parachutes also were used to slow the descent. The capsule then splashed down in the sea, and was picked up by naval vessels assigned to the task.

You can watch a shuttle return from space on NASA TV from a few hours before landing. This covers the time from the deorbit burn until well after landing. There is a link to the site in the Web Links to the left. Shuttle missions don't happen very often, but you will still find something of interest to watch instead and there are video files of past missions in the ' Video Gallery' within the NASA site.

Will all space crafts return to earth?

No. It is highly unlikely that all spacecraft will be returned to Earth. With the development of the VASIMR engine, it is possible that we could indeed intercept the Voyager spacecraft and bring them back for museum exhibit, but right now it is most likely that many spacecraft are gone for good.
