THEMIS Image of the Day, October 27, 2016. Today’s VIS image is of Palikir Crater in Terra Sirenum. The inner rim of the crater is dissected with numerous gullies. In higher resolution images from other imagers these gullies are the location of recurring slope lineae (RSLs), which appear to grow and retreat as seasons change.
