Dunes on the Martian !

Dunes are familiar features on the Earth and also occur on the Mars ,Saturn and Saturn Moon. What is common is an atmosphere, plus substantial amounts of loose sand particles. Mars is the most closely studied by the scientists. Scientists are tracing the movement of dust over Martian aeons using a high-definition camera from orbit. Recently scientists have shared a picture of barchan dunes formed by the Red planet. The Martian desert is a geologic wonder. The Mars Reconnaissance Orbiter's powerful camera recently captured a brilliant image of the sand dunes inside a Martian crater, this is located on the southern hemisphere of the Red planet. These are the star dunes. The camera that captured the image is called HiRISE or the High Resolution Imaging Science Experiment. Orbiter was launched in 2006 :-) its been 16 years it has been capturing images of valleys, craters, dried-up rivers. Up in the space and away from the intense martian dust storms !!!
