Identifies discontinuous TOF behavior in three-body Earth-Moon transfers and augments grid search with a diffusion model, reporting 47-56% better convergence and 39-40% time savings for different orbital altitudes.
Neural surrogates trained with scaling laws and self-similar transformations accurately approximate low-thrust trajectory costs and reachability while generalizing across orbital parameters.
A physics-constrained inverse-problem framework identifies graph-based lumped-parameter thermal models from temperature measurements for spacecraft digital-twin applications.
NanoTug swarms can stabilize and de-orbit debris via analytical sizing, Lyapunov attitude control, and thruster task allocation, with predefined surface distributions outperforming random ones in simulations.
NExT-FRVF operational modal analysis method validated on numerical beam model and real ISS acceleration data, claiming better performance than NExT-ERA and SSI under noise.
The SKA is described as a key future tool for technosignature searches due to its sensitivity, field of view, and resolution, requiring high temporal and spectral resolution data products.
