Automated Lunar Crater Detection with Edge-Based Feature Extraction and Robust Ellipse Refinement
Automated detection of impact craters is essential for planetary surface studies, yet it remains a challenging task due to variable morphology, degraded rims, complex geological settings, and inconsistent illumination conditions.

The self‐secondary crater population of the Hokusai crater on Mercury [PDF]
AbstractWhether or not self‐secondaries dominate small crater populations on continuous ejecta deposits and floors of fresh impact craters has long been a controversy. This issue potentially affects the age determination technique using crater statistics.

Volcanic History and Eruption Processes of Blue Lake Crater, Tongariro [PDF]
Blue Lake Crater (BLC) is a volcanic crater lake situated on the northern end of the Tongariro Volcanic Centre (TgVC) and is one of at least 11 vents that have been active since c. 25 ka.

Erosion rate and previous extent of interior layered deposits on Mars revealed by obstructed landslides [PDF]
We describe interior layered deposits on Mars that have obstructed landslides before undergoing retreat by as much as 2 km. These landslides differ from typical Martian examples in that their toe height increases by as much as 500 m in a distinctive ...

Lunar orbiter image matching is a critical process for achieving high-precision lunar mapping, positioning, and navigation. However, with the Moon’s weak-texture surface and rugged terrain, lunar orbiter images generally suffer from inconsistent lighting

Products and Processes of Cone-Building Eruptions at North Crater, Tongariro [PDF]
North Crater occupies the north-western quadrant of the Tongariro Volcanic Centre and represents one of at least eleven vents which have been active on Tongariro since the last glacial maximum.

The diameter of craters formed by spheres of varying mass dropped into sand at low speed was studied. The relationship between the diameter of the crater formed and the kinetic energy of the projectile at impact was found to be of the same general form ...
