Ejecta blanket

Immediately after an impact event, the falling debris forms an ejecta blanket surrounding the crater.

[7] Ejecta blankets are found on the terrestrial planets (e.g., Earth, Mars, and Mercury) and satellites (e.g., Moon).

[3][2] Lunar fresh impact craters preserve continuous ejecta blanket that are characterized by blocky and high albedo materials.

[11] The low gravity and lack of atmosphere (air less bodies) favors the formation of the impact cratering and associated ejecta black on the surface of moon and Mercury.

These information also give an idea about the planetary environment e.g., gravity and atmospheric effects[18] associated with the impact cratering.

Studying impact ejecta is an excellent sampling environment for the future in-situ lunar exploration.

[18] Based on the structure, ejecta blanket are described as rampart, lobate, butterfly, splosh, sinuous, etc.

[19] Many factors determine the extent of ejecta blanket that ranging from size and mass of impactor (meteorite, asteroid, or comet), surface temperature, gravity and atmospheric pressure of target body, the physical characteristics of target rock.
