The resulting bolide light curves capture temporal brightness variations as these objects traverse increasingly dense atmospheric layers, providing essential information on meteoroid entry dynamics, fragmentation behavior, and atmospheric energy deposition processes. The Center for Near-Earth Object Studies' (CNEOS) continuously expanding fireball database offers a globally comprehensive archive of bolide events, including light curves and associated metadata. Events associated with infrasound detections allow direct correlations between acoustic signatures and light curve features, therefore enabling detailed analyses of fragmentation dynamics and energy deposition. Here, we introduce Bolide Light-curve Analysis and Discrimination Explorer (BLADE), a robust and high-fidelity framework specifically designed to analyze bolide light curves for objects detected from space. BLADE incorporates a processing pipeline integrating Savitzky-Golay filtering, prominence-based peak detection, and gradient analysis, enabling systematic identification and classification of fragmentation events and their associated energy release characteristics. Preliminary results demonstrate that BLADE reliably distinguishes distinct bolide behaviors, providing an objective, scalable methodology for characterization and analysis of large bolide light curve data sets. This foundational work establishes a novel pathway for advanced bolide research, with promising applications in planetary defense and global atmospheric monitoring. Future research should adopt an integrative approach combining CNEOS optical data with complementary infrasound measurements, further clarifying relationships between bolide energy deposition and acoustic signatures, thus refining our understanding of meteoroid and asteroid atmospheric entry processes.2025AJ....170..153Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/170/153CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/comets : Database of the orbital elements of comets (Rocher, 2007)J/AJ/156/60 : Thermal model fits for short-arc NEOs: NEOWISE (Masiero+, 2018)J/A+A/667/A157 : 824 fireballs observed in 2017-2018 (Borovicka+, 2022)J/A+A/679/A148 : Compositional properties of NEOs (Sergeyev+, 2023)J/A+A/674/A50 : Near-Earth Object (NEO) properties (Deshapriya+, 2023)J/A+A/682/A29 : Detection of the Yarkovsky effect on NEAs (Fenucci+, 2024)J/A+A/704/A241 : Calibrated spectra of 31 fireballs (Vojacek+, 2025)http://cneos.jpl.nasa.gov/fireballs/ : CNEOS fireball database (NASA JPL)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/170/153https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/170/153http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/170/153https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/170/153https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/170/153http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/170/153GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/170/153/table1List of events and output classificationsrecnoRecord number assigned by the VizieR team.
