#PPOD: This image shows a new impact crater on Mars that formed between July and September 2018. It's notable because it occurred in the seasonal southern ice cap and has apparently punched through it, creating a two-toned blast pattern. The impact hit the ice layer, and the tones of the blast pattern tell us the sequence. When an impactor hits the ground, the force is tremendous, like an explosion.
