Heliocentric distance dependence of zodiacal light observed by Hayabusa2#

open access: yesEarth, Planets and Space, 2023
Zodiacal light (ZL) is sunlight scattered by interplanetary dust particles (IDPs) at optical wavelengths. The spatial distribution of IDPs in the Solar System may hold an important key to understanding the evolution of the Solar System and material ...

Particle size distributions inside and around the artificial crater produced by the Hayabusa2 impact experiment on Ryugu

open access: yesEarth, Planets and Space, 2022
Japanese Hayabusa2 spacecraft has successfully carried out an impact experiment using a small carry-on impactor (SCI) on an asteroid (162173) Ryugu. We examine the size distribution of particles inside and outside an artificial impact crater (the SCI ...
