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.
