Decoding a Small, Fresh Impact Site

Decoding a Small, Fresh Impact Site
The details in the appearance of this small impact site give clues to its formation and reveal information about the local subsurface. The presence of rays reaching as far as 2.5 kilometers, which are fully captured in this image and have not yet disappeared, attests to its freshness.

The “missing ejecta” in the lower part of the image occurs only in oblique impacts and along the impact direction. Dark material around this 200-meter crater has been excavated from no more than just a small fraction of the crater diameter.

Near the crater rim there are many scattered clasts at least meters in diameter, representing bedrock fractured in the impact process.
