High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
A Mission to Demonstrate Rapid-Response Flyby Reconnaissance for Planetary Defense
Nancy L. Chabot, Justin A. Atchison, Rylie Bull +13
International and U.S. strategies and protocols have identified the need to develop rapid-response spacecraft reconnaissance capabilities as a priority to advance planetary defense…
A Contact Binary Satellite of the Asteroid (152830) Dinkinesh
Harold F. Levison, Simone Marchi, Keith S. Noll +3
Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830)…
Impact disruption of Bjurböle porous chondritic projectile
Tomas Kohout, Maurizio Pajola, Assi-Johanna Soini +10
The ~200 m/s impact of a single 400-kg Bjurböle L/LL ordinary chondrite meteorite onto sea ice resulted in the catastrophic disruption of the projectile. This resulted in a signif…
Macro-scale roughness reveals the complex history of asteroids Didymos and Dimorphos
Jean-Baptiste Vincent, Erik Asphaug, Olivier Barnouin +22
Morphological mapping is a fundamental step in studying the processes that shaped an asteroid surface. Yet, it is challenging and often requires multiple independent assessments by…
