Although no known asteroid poses a threat to Earth for at least the next century, the
catalogue of near-Earth asteroids is incomplete for objects whose impacts would produce …

Some active asteroids have been proposed to be formed as a result of impact events.
Because active asteroids are generally discovered by chance only after their tails have fully …

Abstract On 26 September 2022, NASA's Double Asteroid Redirection Test (DART) mission
successfully impacted Dimorphos, the natural satellite of the binary near-Earth asteroid …

Abstract 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 …

Abstract The Double Asteroid Redirection Test (DART) spacecraft will impact into the
asteroid Dimorphos on 2022 September 26 as a test of the kinetic impactor technique for …

Abstract We present deep Hubble Space Telescope images taken to examine the ejecta
from the DART spacecraft impact into asteroid Dimorphos. The images reveal an extensive …

The Hayabusa2 mission impact experiment on asteroid Ryugu created an unexpectedly
large crater. The associated regime of low-gravity, low-strength cratering remained largely …

We overview various efforts within the DART Investigation Team's Ejecta Working Group to
predict the characteristics, quantity, dynamical behavior, and observability of DART impact …

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 …

We present a series of numerical simulations using a shock physics smoothed particle
hydrodynamics code, investigating energetic impacts on small celestial bodies …
