Description
English: Barchan dunes on Mars, in Lyot crater, as seen by HiRISE on the Mars Reconnaissance Orbiter. From Wikipedia's article on Lyot crater: Lyot Crater is the deepest point in Mars's northern hemisphere. The image below of Lyot Crater Dunes shows a variety of interesting forms: dark dunes, light-toned deposits, and dust devil tracks. Light-toned deposits are widely believed to contain minerals formed in water. Research, published in June 2009, described evidence for liquid water in Lyot crater in the past.
Ελληνικά: Μηνοειδείς θίνες στην επιφάνεια του Άρη, στον κρατήρα Λιό (Lyot). Το ανοιχτόχρωμο υλικό πιστεύεται ότι αποτελείται από πετρώματα που σχηματίστηκαν με την παρουσία νερού. Εικόνα από το τηλεσκόπιο HiRISE, στη διαστημοσυσκευή Mars Reconnaissance Orbiter της NASA.
