Unmanned
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.
there is no man in the space craft
Unmanned - Space probes are a form of robotic spacecraft.
Manned spacecraft generally require a much higher data collection time than unmanned stations
Some disadvantages of manned spacecraft include the high costs associated with designing, building, and maintaining them, as well as the increased risk to human life compared to unmanned missions. Manned spacecraft also have limitations in terms of the distance and duration they can travel compared to unmanned probes.

Spacecraft is the generic term there are both manned and unmanned types such as satellites for the unmanned variety.
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 Sputnik program consisted primarily of unmanned missions, with the first satellite, Sputnik 1, launched in 1957 as a robotic spacecraft. However, it eventually led to manned space missions, such as Vostok 1, which carried Yuri Gagarin into space in 1961. Thus, while the initial Sputnik missions were unmanned, they played a crucial role in the development of human spaceflight.
Manned spaceflight involves sending astronauts on spacecraft to carry out missions, while unmanned spaceflight sends robotic probes or spacecraft without crew. Manned missions require life support systems and capabilities for human presence, while unmanned missions can be more cost-effective and versatile for certain scientific objectives.
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.
Space-docking is the procedure by which spacecraft connect with other spacecraft in space. This is accomplished by careful manuevering, contact at a slow speed, and the interlocking of latches to secure the craft together. Docking is done with both manned and unmanned spacecraft, the connection allowing transfer of goods or material, or controlled access from one vehicle to the other. (For example, a manned vehicle might dock with a satellite to keep it steady while conducting repairs. Alternately, an astronaut can "spacewalk" away from his vehicle and attach himself to the satellite.)
"Manned" refers to vehicles or operations that are operated by human beings, typically involving crew members on board, such as in manned spacecraft or aircraft. In contrast, "unmanned" describes vehicles or systems that operate without human presence, often controlled remotely or autonomously, like drones or robotic spacecraft. The terms are commonly used in aviation, space exploration, and military contexts.
