Uncontrolled collisions with such fragments can damage spacecraft, threaten human missions, and jeopardize the long-term safety of spaceflight operations. Detecting and characterizing small debris—particularly in the sub-millimeter to millimeter range—remains a major challenge as far as small particles size lies below the effective resolution of most ground-based radar and optical systems. To address this, we present an integrated experimental–computational framework that combines high-speed flow visualization with machine learning–based recognition. Shock tube experiments at rarified air flow velocities from 50 up to 900 m/s were used to reproduce conditions representative of particle motion. Particle dynamics were recorded using high-speed shadowgraphy and processed through two complementary pipelines: a contour-based algorithm extracting geometric parameters (width, height, area) together with average brightness relative to the background, and a YOLOv11 deep learning model trained on annotated datasets for real-time particle detection and trajectory reconstruction. The method enables automated generation of particle size distributions, brightness statistics, x–t diagrams, and velocity–time profiles for particles in the 10 μm–5 mm range. The novelty of this work lies in combining high-speed laboratory shadowgraphy with both classical computer vision and deep learning methods, enabling simultaneous extraction of geometric, optical, and kinematic particle characteristics with direct relevance to orbital debris studies. By linking controlled laboratory experiments with scalable computer vision tools, this approach provides a basis for studying fine-particle debris dynamics, validating flow models, and advancing space situational awareness capabilities for debris detection and mitigation.</div></div>","PeriodicalId":44971,"journal":{"name":"Acta Astronautica","volume":"238 ","pages":"Pages 1030-1039"},"PeriodicalIF":3.4,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The autonomous navigation system is tailored for a non-holonomic, non-skid-steering lunar rover prototype equipped with four independently steerable wheels, drawing inspiration from cutting-edge designs employed in recent proposals, such as NASA’s RP15, NASA’s VIPER, and ESA’s EMRS. The proposed architectural framework leverages a behavior-tree-based approach to integrate path planning, maneuver selection, and secure trajectory tracking, enabling the rover to dynamically adapt its locomotion mode to terrain conditions and operational needs, such as dead-end navigation, solar panel alignment, or terrain stability, while prioritizing safety and energy efficiency for reliable, sustainable operation. The performance of the autonomous maneuvering strategy is validated through extensive simulations and real-world field tests with the European Moon Rover System (EMRS) prototype at the TAS-I RoXY outdoor facility in Turin.

In the absence of cost constraints, other limitations, including sustainability considerations, may soon become the primary barriers to further expansion. Assessments of orbital carrying capacity help map these emerging constraints to sustainable levels of satellite activity. While most prior efforts in defining capacity have focused on constraining satellite populations to avoid runaway debris growth, other factors also warrant attention. This work introduces an operational feasibility constraint that limits the acceptable rate of close approaches between tracked objects, beyond which the cadence of collision avoidance maneuvers would make operations infeasible. Using the full public U.S. catalog of two-line elements in low Earth orbit, approximate conjunction nodes are identified based on Keplerian orbit geometries. The resulting operational capacity framework is used to evaluate the sustainability of current orbital populations and to identify key trends in recent history to inform future deployments and operator behavior. By defining operational criticality, occupation, and capacity in consistent and interpretable units, this work shows how satellite populations interact and, if overpopulated or uncoordinated, stifle each other’s ability to operate effectively.</div></div>","PeriodicalId":44971,"journal":{"name":"Acta Astronautica","volume":"238 ","pages":"Pages 769-778"},"PeriodicalIF":3.4,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-resolution digital elevation models (DEMs) of PSRs are crucial for their exploration and scientific research. However, existing datasets, such as the Lunar Reconnaissance Orbiter Narrow Angle Camera (LRO NAC) dataset, do not visualize the interior of PSRs, while the Lunar Orbiter Laser Altimeter (LOLA) data are insufficient to capture adequate topographic details. ShadowCam is a newly deployed camera onboard the Korea Pathfinder Lunar Orbiter (KPLO), with a highly sensitive imaging ability for PSRs based on faint secondary illumination. This paper presents a novel approach, termed shape-from-shading with secondary illumination (SfS-SI), for 3D surface reconstruction of PSRs using ShadowCam images. The approach takes monocular ShadowCam images, a corresponding low-resolution DEM, and information on the direct solar illumination as input. A view factor-based method is incorporated into the approach to reconstruct the secondary illumination from the surrounding environment. The output is a high-resolution DEM of the same resolution as the input ShadowCam images. The proposed approach has been validated using ShadowCam images covering the PSR of the Shackleton crater at the lunar south pole. The results indicate that the approach can reconstruct pixel-wise 3D topographic details in PSRs and achieve a geometric accuracy of 0.34–1.56 m compared with the direct LOLA measurements.
