Ring‐Mold Craters on Ceres
Ring-mold craters are a special kind of impact crater that looks like the ring molds used in baking. So far, they have been identified on Mars and are believed to […]
Late Heavy Bombardment Gives Mercury a Hole New Look
Recent modeling by Steve Mojzsis and colleagues suggests that the large volume of impactors during the late accretion phase almost entirely resurfaced Mercury. This material induced extensive melting (~58%) of […]
Mercury Takes Quite a Beating
In an effort to compare the relative rates of landform evolution on the Moon and Mercury, Caleb Fassett of NASA’s Marshall Space Flight Center and his team measured the depth-to-diameter […]
Ceres’ Bright Spots Come Back Into View
The two brightest spots on dwarf planet Ceres, which have fascinated scientists for months, are back in view in the newest images from NASA’s Dawn spacecraft. Dawn took these images […]
Dawn Captures Sharper Images of Ceres
Craters and mysterious bright spots are beginning to pop out in the latest images of Ceres from NASA’s Dawn spacecraft. These images, taken Feb. 12 at a distance of 52,000 […]
MESSENGER Provides First Optical Images of Ice Near Mercury’s North Pole
NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft has provided the first optical images of ice and other frozen volatile materials within permanently shadowed craters near Mercury’s north […]
Dawn Creates Guide To Vesta’s Hidden Attractions
Some beauty is revealed only at a second glance. When viewed with the human eye, the giant asteroid Vesta, which was the object of scrutiny by the Dawn spacecraft from […]
Water in a Martian Desert
Craters once brim-full with sediments and water have long since drained dry, but traces of their former lives as muddy lakes cling on in the martian desert. The images were […]
