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.
the first spacecraft to explore mars is the mariner 4
Unmanned exploring
From 1995 to 2003.
Jupiter has been visited by 8 spacecraft. These were Pioneer 10, Pioneer 11, Voyager 1 and 2, Galileo, Ulysses, Cassini and New Horizons. The very first mission to explore Jupiter was Pioneer 10, an American spacecraft launched in 1972. This was a true pioneering mission in that, before it left Earth, no one knew whether spacecraft could travel through the asteroid belt between here and Jupiter and survive the trip.

scientists use spacecraft without people to explore space because scientists need to know more about space and the solar system
because they are far away from our solar system
The first spacecraft to visit and explore Jupiter was the Pioneer 10 in 1973. The Pioneer 10 was created by NASA and made in the U.S.
A submarine and probably an unmanned one at that due to pressure concerns.
