The evolution of early Earth was significantly influenced by collisions of planetary materials with Earth’s surface. It is generally accepted that these events modified the composition of Earth’s atmosphere and […]
Impact craters and basins are the dominant geologic features of many planetary surfaces. The paucity of large impact basins on Mars (only four are unambiguous: Hellas, Argyre, Utopia, and Isidis) presents […]
After a large collision in the asteroid belt some 470 million years ago (in Ordovician times), many asteroid fragments were tossed into Earth-crossing orbits, collided with the Earth, and […]

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 […]
