1976
The first craft to land on Mars was in 1971 - Mars-3 from the USSR - but did not transmit colour images. The 1976 craft, Viking 1 and Viking 2 from the US, orbited and then landed, transmitting images from a camera with a movable mirror to illuminate 12 photo diodes designed to be sensitive to different frequencies of light.
