Launched in 1975, Vikings 1 and 2 each consisted of an orbiter and a lander – and everything worked as planned.

Scientists had hoped the landers would be able to detect signs of life. Alas, they struck out on that front.

This image shows the highest peak on Mars – the Olympus Mons – a dormant volcano that is three times taller than Everest and covers an area the size of Arizona.

Join Miles this Sunday at 7pm Eastern for an hour-long special on the next Mars landing. The Phoenix Mars lander is scheduled to touch down on the Martian surface during the hour.
