Mineral Abundances Inferred From In Situ Reflectance Measurements of Chang'E‐4 Landing Site in South Pole‐Aitken Basin

Geophysical Research Letters, 2019
During its first two lunar day measurements, the visible and near‐infrared spectrometer on board the Yutu‐2 Rover of the Chang'E‐4 mission acquired six in situ reflectance spectra from the floor of Von Kármán crater within the South Pole‐Aitken basin.

Uncertainty-Aware Vision-Based Landing-Site Perception for Autonomous UAV Landing in Urban Environments

Drones
Autonomous UAV landing in urban scenes requires a perception module that can identify candidate landing surfaces, reject structural and dynamic hazards, and express uncertainty before a downstream controller commits to a landing maneuver.

An Improved Method of Mars Landing Site Evaluation Using Spatial Heterogeneity-Based TOPSIS

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Mars landing site selection requires a multicriteria suitability assessment that balances scientific potential and engineering constraints. However, conventional methods often employ uniform global weighting, which may oversimplify spatial heterogeneity ...
