A century of geological surveying culminates in completion of Korea’s national geological map
National Research Council of Science & TechnologyKIGAM officially completes all 357 sheets of Korea’s 1:50,000 National Geological Map, marking the culmination of more than a century of national geological surveying since the first map sheet was published in 1924. The National Geological Map serves as essential public infrastructure for mineral resource exploration, geological hazard response, groundwater and underground-space utilization, infrastructure development, and geological carbon storage. KIGAM will now advance the map into a seamless, digital and three-dimensional geological information system by integrating GIS, AI, and digital twin technologies.

New adaptive filtering method improves autonomous navigation for deep-space missions
SciOpenResearchers from Wuhan University have developed a new Uncertainty-Aware Filtering (UAF) algorithm that significantly enhances spacecraft autonomous navigation in deep-space environments characterized by weak gravity, strong perturbations, and limited prior knowledge, which is published in the Chinese Journal of Aeronautics (https://doi.org/10.1016/j.cja.2025.103971). The method shows clear advantages over conventional Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) approaches and has been validated using simulations of China’s Tianwen-2 mission to asteroid 311P/PANSTARRS.

Quantum lattice boltzmann method advances toward practical flow simulations on non-uniform meshes
SciOpenQuantum computing offers a promising pathway for accelerating large-scale scientific simulations, but applying it to computational fluid dynamics remains difficult. A new quantum TLFS-LBM framework reported in the Chinese Journal of Aeronautics (https://doi.org/10.1016/j.cja.2026.104176) introduces a fractional-step correction, a coordinate-based streaming matrix, and a multi-circuit strategy to enable practical incompressible-flow simulations on non-uniform meshes and complex boundaries while reducing quantum-circuit resource demands.

A unified framework for small object analysis in UAV imagery: Tracking single target from multiple detected targets
SciOpenSmall target detection and tracking in UAV remote sensing images are key tasks in fields such as security patrols and traffic monitoring. Recently, a framework called the Cropped Target Detection and Tracking Framework, through cropping and random sampling strategies, significantly improves real-time performance while ensuring small target positioning accuracy and tracking robustness, which is published in the Chinese Journal of Aeronautics.

Coupling between carotid hemodynamics and cerebral blood flow during early simulated microgravity
Beijing Institute of Technology Press Co., LtdWith the advancement of long-term crewed deep-space exploration missions, the effects of the microgravity environment on astronauts' brain function have become an important topic in aerospace medicine. The disappearance of the hydrostatic pressure gradient during spaceflight induces cephalad fluid shifts, which can alter cerebral blood flow (CBF) and are closely associated with visual impairment, spatial disorientation, and cognitive decline. However, existing studies have predominantly focused on the steady-state phase during the middle and late stages of microgravity exposure, with insufficient understanding of the characteristics of CBF fluctuations during the early phase of postural transitions. Moreover, as an indicator of terminal perfusion in the cerebral microcirculation, the coupling relationship between CBF and the upstream hemodynamics of the internal carotid and vertebral arteries has not been systematically investigated. In addition, magnetic resonance imaging (MRI) cannot be applied in real time during spaceflight due to its bulky equipment, whereas ultrasound offers the advantages of portability, real-time capability, and radiation-free operation. Therefore, elucidating the association between early macrovascular hemodynamic changes under simulated microgravity and regional CBF alterations, and evaluating the feasibility of using ultrasound parameters as portable predictors of CBF, holds significant scientific importance and application value.
