There's a lot of hype about the Mars Rover program, but the Rovers weren't alone when they reached the surface. What year did the Viking Landers make history by being the first successful spacecraft to land on the Red Planet?

Just seven years after we put a man on the moon, we put spacecraft on Mars. The Viking Landers were the first to touch down on Mars, with Viking 1 landing in July 1976, and Viking 2 landing in September of the same year. In 1971, the Soviets sent a lander to the surface which survived for a few seconds, however, it sent back no science data, so the mission was a bust.
