Planetary defense with the Double Asteroid Redirection Test (DART) mission and prospects

Nature Communications, 2023
NASA’s Double Asteroid Redirection Test (DART) mission intentionally impacted the asteroid Dimorphos on September 26, 2022, and this kinetic impact changed Dimorphos’ orbit around its binary companion Didymos.

Asteroid Photometric Phase Functions From Bayesian Lightcurve Inversion

Frontiers in Astronomy and Space Sciences, 2022
Photometry is an important tool for characterizing the physical properties of asteroids. An asteroid’s photometric lightcurve and phase curve refer to the variation of the asteroid’s disk-integrated brightness in time and in phase angle (the Sun-asteroid-

Boulder size and shape distributions on asteroid Ryugu

Icarus, 2019
In 2018, the Japanese spacecraft Hayabusa2, arrived at the small asteroid Ryugu. The surface of this C-type asteroid is covered with numerous boulders whose size and shape distributions are investigated in this study.

Mirror formation control in the vicinity of an asteroid [PDF]

, 2008
Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

Successful kinetic impact into an asteroid for planetary defence [PDF]

Nature, 2023
The impact of the DART spacecraft on the asteroid Dimorphos is reported and reconstructed, demonstrating that kinetic impactor technology is a viable technique to potentially defend Earth from asteroids. Although no known asteroid poses a threat to Earth

Ejecta from the DART-produced active asteroid Dimorphos [PDF]

Nature, 2023
Some active asteroids have been proposed to be formed as a result of impact events^ 1 . Because active asteroids are generally discovered by chance only after their tails have fully formed, the process of how impact ejecta evolve into a tail has, to our ...
