During a manned mission, you have to keep the man alive and coherent. This means taking food, air, and water into space, as well as designing the spacecraft with enough empty space to be occupied by the human body and a mission timeline that allows for sleeping and rest of the crew member. Secondly, a mission failure means potential loss of human life. None of these provisions need to be taken into account for robotic missions.
1,7-17 were manned apollo missions
Advantages of manned space missions include the ability for humans to conduct real-time decision-making and problem-solving, as well as the potential for greater scientific discovery and exploration. Disadvantages include the high cost and risk associated with sending humans into space, as well as the limitations on how far and long humans can travel compared to unmanned missions.
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.
Manned missions to the moon: there have been eight successful manned missions to the moon, including six landings.

Manned missions allow for real time interaction with the environment instead of waiting for sent commands to be processed, and confirmation returned. But manned missions require expensive, large habitable environments and support systems to keep the astronauts alive.
There are currently no manned missions planned to Mars.
All Apollo missions were manned.

There were six manned Mercury missions, between 1961 and 1963, which were part of the United States' first human spaceflight program. These missions aimed to prove human spaceflight was possible and lay the foundation for future space missions.
There have been seven manned missions to the moon
