Tasks that are performed by sending people into space, as opposed to tasks performed by sending autonomous or robotic vehicles to do the job.
To date there have been 282 manned missions sent into space and more than 1000 unmanned missions.
The USA had 166 total manned missions, USSR (& Russia) had 123 missions and China had 3 manned missions as of December 15, 2010
A space shuttle is a reusable spacecraft meant for manned missions into orbit.
Manned space missions have carried their crew members to low-earth orbit, to lunar orbit, and to the surface of the moon. The most recent manned lunar orbits and lunar landings took place 38 years ago.
None. We have not had a manned mission to Mercury yet. The space shuttle would be unable to make that type of trip.

The manned space program is just what it says. It's a program to send humans into space. Unmanned vehicles have the advantage in that they don't have to return to earth. That means they can go further and stay in space indefinitely. Manned missions however, need to return its cargo back to earth. Manned missions have the advantage in that if something goes wrong, they can usually fix it in space. If something breaks on an unmanned mission, they simply send up another spacecraft. Manned missions also have the added advantage in that people can observe things in space, while unmanned missions simply obey commands from their earth based masters.

The main difference is that a manned Mars mission is a great deal longer.

No. The only manned space missions have been to the Moon.
We have sent rovers to Mars but there have been no manned missions.
