YOLO-Crater Model for Small Crater Detection

Remote Sensing, 2023
Craters are the most prominent geomorphological features on the surface of celestial bodies, which is playing a crucial role in studying the formation and evolution of celestial bodies, as well as in landing and planning for surface exploration. Currently, the main automatic crater detection models and datasets focus on the detection of large and ...

Sequence of infilling events in Gale crater, Mars: Results from morphology, stratigraphy, and mineralogy [PDF]

, 2013
Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine their origin.

Chicxulub central crater structure: Initial results from physical property measurements and combined velocity and gravity modeling

, 2004
The Chicxulub crater in Mexico is a nearly pristine example of a large impact crater. Its slow burial has left the central impact basin intact, within which there is an apparently uneroded topographic peak ring.
