TL;DR: The Lunar Dust Experiment (LDEX) is an in situ dust detector onboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission as discussed by the authors, which is designed to characterize the variability of the dust in the lunar exosphere by mapping the size and spatial distributions of dust grains in a lunar environment as a function of local time and the position of the Moon with respect to the magnetosphere of the Earth.

TL;DR: In this paper, the radial density profile of the particles ejected from the satellite by interplanetary dust grains is calculated by assuming the yields, mass and velocity distributions of the ejecta obtained from laboratory impact experiments onto icy targets and considering the dynamics of the ejected grains in ballistic and escaping trajectories near Ganymede.

TL;DR: In this article, the authors identify the particles in the duut clouds surrounding the Galilean moons by their impact direction, impact velocity, and mass distribution, indicating that the particles have been kicked up by hypervelocity impacts of micrometeoroids onto the satellites' surfaces.

TL;DR: The results from the preliminary examination of this collection, the Stardust Interstellar Preliminary Examination (ISPE), were presented in this article, where extraterrestrial materials were found in two tracks in aerogel whose trajectories and morphology are consistent with an origin in the interstellar dust stream, and in residues in four impacts in the aluminum foil collectors.
