Why it matters

Menrva shows that crater scarcity is also scientific information: Titan's surface can hide and rework impact traces.

What happenedOne of Titan's few large craters, important because of the moon's dense atmosphere and active surface.

الوصف العلمي

Titan requires radar and infrared reading: crater morphology here is tied to atmosphere, precipitation, and organic materials.
