What were Viking 1 and 2?

Viking 1 and 2 were a pair of NASA Mars landers and orbiters that launched in 1975 and arrived in 1976. The orbiters created global maps while the landers examined the surface up close. The landers performed ambitious chemistry experiments to search for life; the results were ambiguous.

Who walked on Mars first?

The amount of data returned by probes increased dramatically as technology improved. The first to contact the surface were two Soviet probes: Mars 2 lander on November 27 and Mars 3 lander on December 2, 1971—Mars 2 failed during descent and Mars 3 about twenty seconds after the first Martian soft landing.
