To date there have been 282 manned missions sent into space and more than 1000 unmanned missions.
Unmanned
whta is the difference between a manned and unmanned spaceflight
There have been seven manned missions, one of which, Apollo XIII, was unsuccessful, and many other unmanned missions. Considering that we haven't been there in almost a half century, the manned missions must be regarded as sort of technological demonstrations rather than the beginning of human ventures into space.
manned space probe is when there are people traveling in a spaceship. whereas unmanned is when there is nobody in a ship unmanned is launched for the first time to a planet to see that a manned can land.

NASA has sent several unmanned space probes to Saturn, but no manned missions.
The manned missions were carried there by the Apollo craft. The unmanned craft were under the Pioneer, Ranger, and Surveyor missions.
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.

No. The Russians have sent unmanned probes, but the only manned missions to the moon were American.

In the Mercury progam there were 20 unmanned launches; of these four carried monkeys (2 rhesus macaque and 2 chimpanzees); and 6 manned missions. Further missions wre planned, but were cancelled in favour of the Gemini program.In the Apollo program there were 6 unmanned missions; and 12 manned mission, of these 6 missions landed on the moon.In addition the four skylab missions used Apollo equipment; as did the Apollo-Soyuz mission. However these were not considered to be part of the Apollo program.
