Full Answer

Humans first visited space in the 1960s, with the United States and the former Soviet Union both sending astronauts to orbit the earth. Manned space exploration peaked in 1969 when Americans Neil Armstrong and Buzz Aldrin landed on the moon. Numerous satellites have photographed Mars, and the United States in 1976 landed two probes, Viking 1 and Viking 2, and two rovers, Spirit and Opportunity, on the Martian surface in 2004. This has been the extent of human interaction with the Red Planet. However, the scientific community is diligently working on a mission to send man to Mars.
