Mars Scientists are asking students from around the world to help them understand the red planet. Send in a rock collected by you or your classroom from your region of the world and we will use a special tool like the one on the Mars Exploration Rovers to tell you what it's made of.
If you've already sent in a rock and received your certificate, you can find it by entering the rock ID (like RATW02759) on your certificate here:
Or browse through all the rocks we've received by clicking on this map:
