If you were roving across Mars with Opportunity, what tunes would you rock out to? This is the Opportunity Pancam "Rub al Khali" panorama, acquired in the plains of Meridiani on sols 456 to 464 (6 to 14 May 2005) from a position about 2 km south of Endurance crater at a place known informally as "Purgatory Dune," where the rover was stuck in the deep fine sand for more than a month. • Can you say new desktop and phone wallpapers?
