The first man-made object to land on Mars arrived 40 years ago this month, and NASA's Curiosity rover should soon depart for the Red Planet. Here is a look at where humankind's many Mars landers have touched down, and where the planet betrays a history of all-important liquid water. Find out more in Exploring the Red Planet
