Currently all missions to Mars are unmanned. The only human aspect of these missions are the scientist and engineers that build the satellites or rovers/landers and the people that control them (mission control).
No human has been to Mars yet. All missions to Mars have been unmanned robotic missions. However, there are plans for human missions to Mars in the future, with NASA targeting the 2030s for potential crewed missions.
Yes, there have been several unmanned missions to Mars conducted by space agencies such as NASA and ESA. These missions have included rovers like Curiosity and Perseverance, as well as orbiters like the Mars Reconnaissance Orbiter. Scientists are also planning future manned missions to Mars as part of ongoing exploration efforts.
As of now, no humans have traveled to Mars. All Mars missions have been unmanned robotic missions. Plans for crewed missions to Mars are being developed by various space agencies and private companies for the future.
As of now, no human has visited Mars. Unmanned missions, like those from NASA's rovers, have been conducted to explore the planet's surface. Plans for crewed missions to Mars are being developed for the future.
Yes, Voyager II has. (Voyager II is an unmanned space probe).
Yes, there are 44 missions.
Many American spacecraft have reached Mars. All were unmanned, however.
Humans, no. Unmanned spacecraft, yes.
One of the best places for one to find images of Mars is on the NASA website. NASA has had numerous unmanned missions to Mars and has a vast collection of pictures of the planet. The latest such mission is the Mars Curiosity Rover.
I am not sure if by "space mission" You mean a mission to a distant object or into deep space or manned or unmanned. Voyager I and II are unmanned deep space missions, both launched in 1977. More than thirty years later they are both still running (as of today: March 10, 2010). The unmanned Mars Exploration Rovers Spirit and Opportunity were rover launched to Mars in 2004. Opportunity is still running fine but Spirit is stationary because two of its six main wheels have stalled. The Apollo Missions were manned moon missions in the nineteen-sixties and seventies. They were also very successful.
Curiosity is unmanned.
As of now, a total of 12 astronauts have walked on the surface of various planets in our solar system. These missions include the Apollo moon landings and Mars rover missions. There are plans for future manned missions to Mars and potentially other planets as well.
