Manned spacecraft are designed to carry humans on board, while unmanned spacecraft do not have human crew members and are controlled remotely or autonomously. Manned spacecraft require life support systems and provisions for crew safety, while unmanned spacecraft can be smaller and more specialized for scientific missions.
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 satellite is an unmanned spacecraft that is used for various purposes, such as communication, weather monitoring, and navigation. It orbits the Earth or other celestial bodies to perform its functions.
I is nearly impossible to put a date on the first unmanned rocket, because the chinese were building unmanned rockets before we discovered them. By the time of the Revolutionary War in America, unmanned rockets were a weapon of war used by the British.
Unmanned - Space probes are a form of robotic spacecraft.
There are no people on it. That means it is unmanned.

Nobody. It was unmanned.
If it was "unmanned" -nobody flew it.
These words are used to describe the modes of transportation, used for going into the space. Maned rocket or a maned shuttle means that it is carrying humans in it. But an unmanned rocket or a shuttle doesn't carry any human.
normally they are unmanned but sometimes they do have people sent up

whta is the difference between a manned and unmanned spaceflight
The cast of Unmanned - 2008 includes: Paul Birchard
Piranha Unmanned Surface Vessel was created in 2010.
Finding ways to power the spacecraft or probe is one problem of unmanned spaceflight. Unmanned spacecraft have limited abilities and they don't have the ability to do follow up testing.
