NASA's Double Asteroid Redirection Test (DART) mission was the first to demonstrate asteroid deflection, and the mission's Level 1 requirements guided its planetary defense investigations. Here, we summarize DART's achievement of those requirements.

Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the process of the impact ejecta evolving into a tail has never been direct

The Rochechouart impact structure, located in the western part of the Massif Central in France, has been suggested to be one of the largest impact structures in western Europe. Various age datings have placed the event in a span from the Late Triassi

Impact Induced Motion of Boulders and Their Effect on Ejecta Emplacement on Rubble-pile Targets

Autor: Jens Ormö, Sabina D. Raducan, Robert Luther, Martin Jutzi, M. Isabel Herreros, Gareth Collins, Kai Wünnemann, Valentin Mauri

Introduction: Asteroids smaller than about 50 km in diameter are the result of the break-up of a larger parent body [1]. They are often considered to be rubble-pile objects, aggregates held together only by self-gravity or small cohesive forces [2, 3

Ocean Resurge Deposits at the Rochechouart Impact Crater, France: Hints to Target Environment and Event Magnitude

Autor: Jens Ormö, Erik Sturkell, Philippe Lambert

Introduction: The Late Triassic Rochechouart impact structure, Massif Central, France, has been suggested to be one of the largest impact structures in western Europe. A pre-erosion diameter of 40-50km has been proposed [1]. However, the lack of a di
