Mars HiRISE Image

Think you're seeing trees on the Martian surface? Guess again - it's an optical illusion. The "trees" are actually dark streaks on the sand caused by evaporating gases. This image is one of thousands in the HiRISE collection.

When someone says the word “Mars,” what image comes to your mind? Most likely, you picture a dusty, cratered, rust-colored wasteland. But thanks to the High Resolution Imaging Science Experiment (HiRISE), you can see our planetary neighbor like never before. The HiRISE camera, part of the Mars Reconnaissance Orbiter, is operated by NASA and the University of Arizona and is currently the most powerful camera on any NASA spacecraft. The beautiful images it has sent back to Earth highlight the fact that while parts of Mars may seem familiar to us, other features of the Red Planet are bizarre and mysterious.

Unlike Mars rovers, which are designed to investigate only a tiny portion of Mars’s land area, the HiRISE camera orbits the entire planet and can be directed to take images of any interesting area. It has taken thousands of detailed images, all of them available to view online. Now, with the release of the HiWish public suggestion tool, you can help determine future target areas for the camera. After registering for the program, you can browse large-scale areas of the Martian surface and send in your suggestion for where HiRISE should take its next close-up image. The site also allows you to track your suggestions and receive notifications when your images are taken.

If you’re interested in finding out more about the Red Planet, plan to attend our Science 360 show “Mission to Mars,” which returns to the MPSC schedule on February 6, 2010.
