Implications for the origin and evolution of Martian Recurring Slope Lineae at Hale crater from CaSSIS observations

Pajola, M.; Cremonese, G.; Thomas, N. +9 more

Recurring Slope Lineae (RSL) are narrow, dark features that typically source from rocky outcrops, incrementally lengthen down Martian steep slopes in warm seasons, fade in cold seasons and recur annually. In this study we report the first observations of RSL at Hale crater, Mars, during late southern summer by the Color and Surface Science Imaging…
