"One of the most profound discoveries that has emerged from the past 40 years of space exploration is that environmental conditions like those that we enjoy on Earth are exceedingly rare. However, there is a short list of special places in our solar system that astronomers believe may once have been--or may still even be--very much Earth-like. Mars is at the top of that list." (PHYSICS WORLD) This article examines what has been learned about Mars since the 1960s from information sent back by numerous Mars orbiters and landers and explains ongoing and upcoming missions.
