Material Property Sensitivity of Light Curve Attitude Estimation for the Lunar Trailblazer
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract The Lunar Trailblazer (LTB) spacecraft launched on 27 February 2025, toward a planned low‐lunar orbit. Eleven hours into its mission, contact with Trailblazer was lost, and recovery efforts began. Estimating the orientation and angular velocity state of Trailblazer was central for recovery to determine whether and when the vehicle could be ...

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity
Electron, Volume 4, Issue 2, May 2026.This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.
