People send spacecrafts to space to explore what it is like in space and to take pictures to see if there is going to be life on a planet. They also see where things are.
Hope that helps!
Spacecrafts are launched into space using rocket propulsion systems. Rockets generate enough thrust to overcome Earth's gravity and propel the spacecraft into orbit. Once in orbit, spacecrafts can travel further into space with the help of additional propulsion systems like thrusters or ion engines.
When two spacecraft are joined in space it is called docking.
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.
Because humans have a need to reach space, and there is no other way to reach space. Reaching space has many benefits, including communication, navigation, mapping and exploration. New space crafts are constantly being invented because new technology allows for safer and more efficient space crafts.
Yes, to further the exploration of space, and medical research.

Yes spacecrafts have cameras as they are used in weather warnings.

No the Apollo spacecrafts are not reusable, like the space shuttles.
Term used they are docking.

because spacecrafts can see that the earth spins from outer space :)
