A panoramic image that NASA's Curiosity Mars rover took from a mountainside ridge provides a sweeping vista of key sites visited since the rover's 2012 landing, and the towering surroundings.
Layers, probably sedimentary in origin, have undergone extensive erosion in this image from NASA's Mars Reconnaissance Orbiter (MRO) of Shalbatana Valles, a prominent channel that cuts through Xanthe Terra.
Some Mars experts are eager and optimistic for a dust storm this year to grow so grand it darkens skies around the entire Red Planet. This type of phenomenon in the environment of modern Mars could be examined as never before ...
