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…
Spectro-photometry of Phobos simulants: II. Effects of porosity
Antonin Wargnier, Olivier Poch, Giovanni Poggiali +13
Surface porosity has been found to be an important property for small bodies. Some asteroids and comets can exhibit an extremely high surface porosity in the first millimeter layer…
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…
Spectro-photometry of Phobos simulants: I. Detectability of hydrated minerals and organic bands
Antonin Wargnier, Thomas Gautier, Alain Doressoundiram +12
Previous observations of Phobos and Deimos, the moons of Mars, have improved our understanding of these small bodies. However, their formation and composition remain poorly constra…
