Why is most space exploration accomplished spacecraft that do not have crews on board?

It is also cheaper in many ways, since a human crew needs many things to stay alive including food, water, air, and bathroom and sleeping facilities. All of these require making a spacecraft bigger and heavier and therefore harder to get into space. You also do not have to have a return trip for an unmanned probe. A probe can be made to stay in space or on another planet and collect data until it stops working.

What is an Apollo spacecraft?

What happens to the International Space Station when the Shuttle is retired next year?
After the Space Shuttle is retired in late 2010, the International Space Station will still continue to operate as usual. By the time the Space Shuttle is retired, all of the major components of the Space Station will be on orbit, so it will finally be complete. Crews to the space station will need to be delivered solely by Russia's Soyuz spacecraft, although if Project Constellation continues as planned, the Orion spacecraft will be used to deliver American crews. Other vehicles might also be developed to deliver crews, because it's expensive for NASA to buy seats for American astronauts onboard Russian spacecraft. Supplies will be delivered to the Space Station through Russian Progress supply crafts, Japanese H-II Transfer vehicles, and European Automated Transfer Vehicle (ATV) spacecraft.
How were the Apollo missions different from the Gemini missions?
Gemini had two man crews and their objectives were to learn how to fly, navigate, rendezvous, and dock spacecraft while in orbit. In addition, they had to learn how to work outside of the spacecraft in zero gravity and discover the long term impacts of spending the amount of time in space it would require to go to the moon and back. All of these mission objectives built a knowledge base which then allowed the US to do all the things we needed to do in order to complete a mission to the moon The Apollo program had three man crews and their objective was to take the collected knowledge of the Mercury and Gemini programs and fly to the moon and land there. Once there their objectives were to conduct scientific research about the origin and geological make up of the moon.
What do crews often use to reach the space station?
Up until today, they used the Shuttle. Since this was the last shuttle mission, they will need to use the Soyuz space capsules until NASA comes up with a replacement vehicle, which is not even on the drawing board.
