Palikir Crater has long been of interest since we first spotted the phenomena of recurring slope lineae (RSL) in 2013, those dark streaks that appear in the Martian summer, vanish in the winter and then re-appear when the season changes. This image is part of a monitoring sequence as we keep investigating what RSL actually are and how they form. Palikir is located in the southern part of the much larger Newton Crater in Terra Sirenum.
