Scientists examine effects of wind on Mars
Pasadena, Calif. (UPI) Jan 16, 2008 U.S. scientists have obtained high-resolution images of Mars' wind-driven sand dunes and ridges that might lead to a better understanding of the planet. The pictures were taken by the High Resolution Imaging Science Experiment camera on the Mars Reconnaissance Orbiter. The camera is capable of imaging features less than half a meter -- about 20 inches in size. The scientists said they obtained images of wind-driven sand dunes, ripples and wind-scoured ridges, called yardangs, with complex textures and multiple layers. The researchers from the California Institute of Technology in Pasadena, Calif. -- along with scientists from the U.S. Geological Survey and the universities of Arizona and Colorado -- said their research might help determine important characteristics of past Martian environments. The study appears in the journal Geophysical Research Letters. Community Email This Article Comment On This Article Related Links Mars News and Information at MarsDaily.com Lunar Dreams and more
