Dynamical evolution and surface accretion of DART impact ejecta in the (65803) Didymos system
Xiaoyu Fu, Nicolo Stronati, Stefania Soldini +6
The paper models how debris ejected by the DART spacecraft impact on Dimorphos evolves and deposits on the surfaces of the Didymos binary asteroids, finding that most ejecta escape…

DreamSat-Pose: Spacecraft Pose Estimation from Single-View 3D Reconstructions and Learned 2D-3D Feature Matching
Josiane Uwumukiza, Jocelyn Zhao, Giovanni Lavezzi +5
The paper introduces a single-shot framework that reconstructs a 3D shape of an unknown spacecraft from one image and then estimates its 6-DoF pose by learning dense 2D‑3D correspo…
