Recent advances in modelling of global-scale collisions using smoothed particle hydrodynamics
Christian Reinhardt, Sabina D. Raducan, Thomas Meier +3
Impacts play a fundamental role in shaping the physical and chemical properties of the objects in our Solar System. Given the challenges in replicating such collisions through labo…
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…
The Dynamical State of the Didymos System Before and After the DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +50
NASA's Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the natural satellite of (65803) Didymos, on 2022 September 26, as a first successful test of kinetic…
Rapid formation of binary asteroid systems post rotational failure: a recipe for making atypically shaped satellites
John Wimarsson, Zhen Xiang, Fabio Ferrari +4
Binary asteroid formation is a highly complex process, which has been highlighted with recent observations of satellites with unexpected shapes, such as the oblate Dimorphos by the…
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 signifi…
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…
Lessons learned from NASA's DART impact about disrupting rubble-pile asteroids
S. D. Raducan, M. Jutzi, C. C. Merrill +4
We present a series of numerical simulations using a shock physics smoothed particle hydrodynamics (SPH) code, investigating energetic impacts on small celestial bodies characteris…
Direct -body simulations of satellite formation around small asteroids: insights from DART's encounter with the Didymos system
Harrison F. Agrusa, Yun Zhang, Derek C. Richardson +18
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos-Dimorphos binary, which was the first small…
Momentum Transfer from the DART Mission Kinetic Impact on Asteroid Dimorphos
Andrew F. Cheng, Harrison F. Agrusa, Brent W. Barbee +66
The NASA Double Asteroid Redirection Test (DART) mission performed a kinetic impact on asteroid Dimorphos, the satellite of the binary asteroid (65803) Didymos, at 23:14 UTC on Sep…
Successful Kinetic Impact into an Asteroid for Planetary Defense
R. Terik Daly, Carolyn M. Ernst, Olivier S. Barnouin +98
While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional de…
Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
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 p…
Constraining surface properties of asteroid (162173) Ryugu from numerical simulations of Hayabusa2 mission impact experiment
Martin Jutzi, Sabina D. Raducan, Yun Zhang +2
The Hayabusa2 mission impact experiment on asteroid Ryugu created an unexpectedly large crater. The associated regime of low-gravity, low-strength cratering remained largely unexpl…
After DART: Using the first full-scale test of a kinetic impactor to inform a future planetary defense mission
Thomas S. Statler, Sabina D. Raducan, Olivier S. Barnouin +38
NASA's Double Asteroid Redirection Test (DART) is the first full-scale test of an asteroid deflection technology. Results from the hypervelocity kinetic impact and Earth-based obse…
Reshaping and ejection processes on rubble-pile asteroids by impacts
S. D. Raducan, M. Jutzi, Y. Zhang +2
Context. Most small asteroids (<50 km in diameter) are the result of the breakup of a larger parent body and are often considered to be rubble-pile objects. Similar structures are…
Effects of impact and target parameters on the results of a kinetic impactor: predictions for the Double Asteroid Redirection Test (DART) mission
Angela M. Stickle, Mallory E. DeCoster, Christoph Burger +30
The Double Asteroid Redirection Test (DART) spacecraft will impact into the asteroid Dimorphos on September 26, 2022 as a test of the kinetic impactor technique for planetary defen…
Predictions for the Dynamical States of the Didymos System before and after the Planned DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +33
NASA's Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, around 23:14 UTC on 26 September 2022, causing a…

S. D. Raducan, M. Jutzi, T. M. Davison +5
The DART spacecraft will impact Didymos's secondary, Dimorphos, at the end of 2022 and cause a change in the orbital period of the secondary. For simplicity, most previous numerica…
