THEMIS: Impact blast scars on crater rim

Impact blast scars in crater rim (THEMIS_IOTD_20180612)THEMIS Image of the Day, June 12, 2018. Today’s VIS image shows part of a crater located north of Hecates Tholus. The radial grooves in the ejecta blanket are still visible around the crater rim.

There is also likely blast damage from the base surge produced by the collapsing cloud of debris that rose directly above the crater in the impact. When the column of debris stops rising, it drops straight down, then shoots outward at ground level, scarring the rim and surrounding landscape.
