Low earth orbit is closer, can be reached more efficiently (less expensively) and meets mission objectives of performing scientific experiments and observations in microgravity. A moon orbiting station would be more expensive to maintain, increase risk to the crew aboard and crews servicing it, without added benefit to the mission of the station.
To date there have been 6 manned missions to the moon, and 20 missions to the International Space Station which has included numerous Space Shuttle and Soyuz missions providing crew, supplies and segments of the station.
The International Space Station is being assembled in orbit around earth. The pieces themselves were built in various places in various nations on earth.
Because the space station is in such a bad orbit for US spacecraft to launch to, it takes about 2 days in space for the shuttle to rendevous with the space station. The space station was built by the US & Russians, spacecraft from both countries had to be able to send supplies up on a regular basis, so the orbit of the ISS is difficult for the shuttle to reach.
what International Space Station is the first fully functioning space station to orbit the earth.
The International Space Station is still in orbit, and is still being constructed.
The International Space Station was first started being built in 1998. It is the largest artificial orbit in space and sometimes at the right time can be seen by the naked eye.

The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
The International Space Station is the only space station currently in orbit.
The International Space Station (ISS) is a space station currently being constructed in orbit around Earth. Construction began in 1998 and is expected to be completed in 2011. It is being built and occupied by many nations at one time, hence the name International Space Station.
The first space station created only to orbit the earth was called plain old, 'Space Shuttle.'
The International Space Station (ISS) is still under construction. The first section was sent up into orbit in 1998, and sections are still being sent up. The station is expected to be completed in 2011.
