Rock Around the World

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 the Mars Spaceflight Facility at Arizona State University will use a special tool like the one on the rovers (Mini-TES) to tell you what it's made of.  Then everyone can compare their rocks to the ones found on Mars.

The scientists will post a picture of your rock on the web, and give you a report on what kind of rock it is.  They'll also send you an official certificate and Mars sticker for your contribution.  Click here to see some of the rocks that have already been analyzed!
