Unmanned - Space probes are a form of robotic spacecraft.
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.
there is no man in the space craft

The most obvious answer to your question is the fact that people have to return to earth, while an unmanned craft can stay in space infinitely. Manned spacecraft require things like oxygen, water, food and communications equipment, none of which are required by an unmanned spacecraft. That means unmanned spacecrafts can be sent into space for a fraction of the cost of a manned spacecraft. So basically, it's much cheaper and safer to send unmanned spacecrafts to explore the universe.

A space probe is an unmanned spacecraft sent into space.

Spacecraft is the generic term there are both manned and unmanned types such as satellites for the unmanned variety.

an unmanned space probe is a satellite orbiting around the planet
Several advantages; mainly:A human needs food, air, and protection. An unmanned craft needs none of these; its use of energy and other "extras" is much less than for a human.An unmanned craft can be sacrificed; there is no moral obligation to return it safely to Earth.In summary, all this makes an unmanned spacecraft much cheaper than a manned spacecraft.
The first unmanned space probe to reach the moon was the USSR's Luna 2, in Sep 1959. The first manned spacecraft to land on the the moon was the USA's Apollo 11, on July 20, 1969.
The term "space probe" is normally limited to unmanned (robotic) spacecraft. So, no, space probes do not have people aboard them.
A space probe is an unmanned device that is sent into space for purposes of exploration. The space shuttle is a manned vehicle meant for research and delivering supplies, equipment, and people into low-Earth orbit.
