I think it might be because probes are cheaper and just in case something goes wrong, it would not end up resulting in loss of life. (Just an opinion though.)
Crewed missions allow for real-time decision-making and problem-solving, offer opportunities for scientific experimentation and research that require human presence, and foster international collaboration and exploration. Additionally, crewed missions can inspire the public and future generations by showcasing human ingenuity and capability to overcome challenges in space.
Advantages of crewed missions include the ability for humans to make real-time decisions, conduct complex tasks, and better cope with unexpected situations. Disadvantages include higher costs, greater risk to the crew's safety, and limitations on mission duration and distance due to life support requirements.
The main difference - is size ! With a crewed space vehicle, you have to make it big enough to accommodate the people, and include their life-support systems, propulsion etc. With an unmanned probe - it only needs to be big enough to house the instrumentation and power (batteries & solar panels).
Crewed space exploration allows for human presence and decision-making, which can adapt to unexpected situations and conduct more complex tasks. However, crewed missions are more expensive, risky, and require life support systems. Space probes are less costly, versatile, and can explore distant and harsh environments without risking human lives, but they lack real-time decision-making and human intuition.
Yes, several space probes have been sent to Mars by various countries, including NASA's Mars rovers, Curiosity and Perseverance. Currently, there are also plans for crewed missions to Mars in the future.

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.

Yes, there are 44 missions.
Spacecraft can be classified into categories such as crewed spacecraft (manned missions), robotic spacecraft (unmanned missions), satellites (for communication, weather monitoring, etc.), probes (for interplanetary exploration), space stations (like the ISS), and landers (for missions to other celestial bodies). Each type serves a specific purpose in space exploration and research.
Exploration of space beyond the moon has been conducted by space agencies such as NASA, ESA, Roscosmos, and private companies like SpaceX. Missions have included probes to planets, moons, asteroids, and comets, as well as the establishment of space stations like the International Space Station. Future plans involve crewed missions to Mars and beyond.

Yes, the Voyager missions were run by NASA and they sent the probes.
As of 2021, over 9,000 rockets have been launched into space since the first one in 1957. This includes rockets carrying satellites, probes, and crewed missions by various space agencies and companies around the world.
