The extinction of the dinosaurs and around three-quarters of all living species was almost
certainly caused by a large asteroid impact 66 million years ago. Seismic data acquired …

Analyses of seismic data from the InSight mission have provided the first in situ constraints
on the thickness of the crust of Mars. These crustal thickness constraints are currently limited …

The~ 180-km-diameter Chicxulub peak-ring crater and~ 240-km multiring basin, produced
by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on …

The formation and evolution of the terrestrial planets were shaped by a bombardment of
large impactors in a cluttered early Solar System. However, various surface processes …

The Cretaceous ended when the Chicxulub asteroid struck the Yucatán platform, and all
deposits and landforms generated are earliest Paleocene in age. Drill core from the …

Abstract Knowledge of the shock behavior of planetary materials is essential to interpret
shock metamorphism documented in rocks at hypervelocity impact structures on Earth, in …

The shallowest intracrustal layer (extending to 8±2 km depth) beneath the Mars InSight
Lander site exhibits low seismic wave velocity, which is likely related to a combination of …

The~ 31-km-wide Hiawatha structure, located beneath Hiawatha Glacier in northwestern
Greenland, has been proposed as an impact structure that may have formed after the …

This study presents petrographic and geochemical characterization of 46 pre-impact rocks
and 32 impactites containing and/or representing impact melt rock from the peak ring of the …

Martian meteorites are rare; therefore, the discovery of new meteorites has the potential to
significantly expand our current understanding of Mars. In this study, we describe four new …
