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 shuttle is a reusable spacecraft designed for human spaceflight, carrying astronauts to and from space. A space probe is an unmanned spacecraft designed to explore other planets, moons, or asteroids without carrying humans. Spacecraft is a general term that encompasses both manned (space shuttles) and unmanned (space probes) vehicles designed for space exploration.
A spaceship is a manned spacecraft designed to carry astronauts, while a space probe is an unmanned spacecraft designed to explore space and gather data without a crew on board. Space probes are typically used for scientific research and exploration missions to planets, asteroids, and other celestial bodies.
Astronauts will use commercial spacecraft, such as SpaceX's Crew Dragon or Boeing's Starliner, to travel to the International Space Station after the retirement of the Space Shuttle. These spacecraft are designed to transport crew to and from the ISS, reducing dependence on Russian Soyuz spacecraft for transportation.
Spacecraft need to be pressurized to provide a breathable environment for astronauts. Without pressure, the fluids in the body would boil due to the low pressure, which is harmful to human health. Pressurization also keeps the spacecraft's structural integrity by maintaining a stable internal pressure against the vacuum of space.
Unmanned space missions are space exploration missions that do not involve human astronauts on board. Instead, spacecraft are sent with robotic systems and instruments to gather data, conduct experiments, or explore celestial bodies. These missions are valuable for studying distant planets, asteroids, and cosmic phenomena without risking human lives.

Without oxygen, astronauts would not be able to breathe and would suffer from hypoxia, which can lead to unconsciousness and eventually death. The lack of oxygen in space can also cause damage to the brain and other vital organs. Special equipment, like space suits and spacecraft, are designed to provide astronauts with a controlled environment that includes a supply of oxygen to prevent these issues.

A spacecraft without people on board is called an unmanned spacecraft or a robotic spacecraft. These types of spacecraft are operated remotely from Earth or operate autonomously.
Yes, astronauts do fart in space. However, without gravity to pull the gas down, the fart doesn't rise so it can linger longer in the spacecraft. Astronauts have to deal with farting by using special filters in their spacesuits.
In space, there is no air because it is a vacuum. This lack of air affects astronauts during space missions because they cannot breathe without a spacesuit or the controlled environment of their spacecraft. Additionally, the absence of air means there is no atmosphere to protect astronauts from harmful radiation and extreme temperatures.
Without the "Space Travel and Exploration" context I'd have said "Customer Service Manager".However, in this particular category, it probably means "Command/Service Module", the portion of the Apollo spacecraft that returned to Earth orbit from the Moon. (The Service Module was the "rocket" part that was discarded and burned up; the Command Module is the cone-shaped part the astronauts were in that actually landed.)
A crew-less spaceship is commonly referred to as an unmanned spacecraft or robotic spacecraft. These spacecraft are designed to operate without any humans on board, carrying out missions such as scientific research, exploration, or satellite deployment.
You may have seen photos or videos of astronauts who appear to be floating through the air while in space. They aren't flying, nor are they really floating, they are falling. Any orbiting spacecraft (such as the space shuttle or international space station) is actually falling around the Earth in a circular pattern. They have achieved enough speed (over 17,000 mph) to continue moving around the Earth without the Earth's gravity pulling the spacecraft down. Astronauts aboard those spacecraft are moving inside the spacecraft and falling along with them at the same speed giving the appearance that they flying or floating inside.
