Scientists need your help!
Welcome to the Mars Public Mapping Project, or (MP)2 for short.
We're trying to identify the coolest images of Mars, and you can help. It's easy! Check out the image at left and rate it by clicking the star scale above: five stars = coolest.
(You can zoom and scroll around to see the full image using the controls, and a click on its ID number takes you to a page with more info about the image.)
For each star-click, you'll see a new image to rate, and you can keep clicking and rating new images for as long as you like.
Scientists could use your help in identifying and tagging different types of surface features so they can create global Martian maps.
Mars is a big place with lots of features and there's plenty to see. The geological features you'll hunt for include craters, volcanos, sand dunes, dust devil tracks, valleys, and lots of others.
If you are not sure you can identify these features on sight, don't worry. We'll show you what typical examples look like. It's all visual and the feature types are not hard to tell apart.
Sound interesting? OK, the first step in going tagging on Mars is to sign up for an (MP)2 user name and password. We do this so you can get recognition for your work and it also lets us make sure you see all-new images each time you contribute. Start by clicking one of the buttons below.

Let's go tagging.
