Nasa's Mars Robotic Exploration:
Mars was explored in flybys by Mariner 4, 6 and 7 in the 1960s and by the orbiting Mariner 9 in 1971 before NASA mounted the ambitious Viking mission, which launched two orbiters and two landers to the planet in 1975. The landers found no chemical evidence of life. Mars Pathfinder landed on the planet on July 4, 1997, delivering a mobile robot rover that explored the immediate vicinity. Mars Global Surveyor is creating the highest-resolution map of the planets surface.
Russia/Soviets Mars Robotic Exploration:
Started in the 1960's with the Mars Program. The last endeavour by Russia was Mars 96.
