TL;DR Summary
ESA's Mars Express HRSC captures a field of bright, sheen-like dunes in Kaiser Crater on Noachis Terra, sculpted by westward winds into transverse and barchan forms; the shiny appearance comes from frost on south-facing slopes, while exposed clay rocks and gullies hint at past water activity in this ancient Martian region.
