Title : Frosty Martian Dunes Entice Earthbound Observers

Dec. 04, 2007
Description : Conspicuous dark streaks atop icy dunes on Mars allure scientists and non-scientists, yet their origin remains a mystery. Perhaps they are small avalanches or patches of sand covered by a thin veneer of ice. Perhaps they formed when cold gas jets of evaporating ice spewed dust onto the surface.

Imagine being able to point a camera at such features from 60 million miles away! Students in Budapest, Hungary effectively did that, selecting this site for observation from orbit through a program that invites the public to help NASA select targets for imaging on Mars.
