THEMIS Image of the Day, July 18, 2018. Today’s VIS image shows a crater on Hephaestus Fossae. The crater is fairly young, as there is only minimal modification of the crater floor.
While it appears that the crater sits of top of the channel, the creation of the crater may have also created the channel. The impact event would have caused subsurface heating, melting any subsurface ice in the region which would have created surface flow to form the channel.
