NASA's Mars Reconnaissance Orbiter has taken lots of pictures of Mars. But this data needs examining. So the science team is asking the public to help out by looking at images taken near the south pole of Mars.
They're asking volunteers to have a look at the pictures and say if each one contains any of the features of interest. There are examples of all of these features so you know what you're looking for. I had a go and found many of the images don't contain any of the things they're looking for. And it gets easier as you go along.
By the way, they always send each image to more than one person, so you needn't feel that you're responsible for an incorrect identification or missing something of importance. The scientists concentrate on the images where different people have spotted one of the things they're looking for.
