## VI. CONCLUSION
|
|
|
|
In this work, we introduce AreoRAG, a framework designed for multi-source planetary spatial data retrieval augmented generation. To address the structural bottleneck of discrete representation failure for continuous spatiotemporal topology and the epistemological conflict between scientific observational divergence and traditional de-falsification mechanisms, we propose two key innovations: Hyperbolic Spatial Hypergraph construction and Physics-Informed Conflict Triage.

The introduction of HySH employs $n$-ary spatial observation hyperedges embedded in hyperbolic space via the Lorentz model, reducing edge complexity from $O(k^2)$ to $O(k)$ while faithfully preserving the hierarchical scale structure of planetary observations through the scale-curvature correspondence principle. The Spatial Outward Einstein Midpoint aggregation operator further ensures that cross-resolution evidence fusion retains fine-scale observational details with a formal outward bias guarantee. Meanwhile, the PICT module fundamentally redefines the role of inter-source conflict in RAG systems — shifting from uniform conflict elimination to physics-informed conflict triage that classifies disagreements by their physical origin and applies differentiated confidence recalibration. The Anti-Over-Smoothing Guarantee (Theorem 2) ensures that scientifically valuable observational divergences are provably preserved rather than suppressed.

Extensive experiments on multi-source planetary observation datasets and general multi-hop QA benchmarks demonstrate that AreoRAG significantly outperforms existing methods in retrieval fidelity, answer accuracy, and scientific faithfulness. In particular, AreoRAG achieves a Conflict Preservation Rate of 91.7% while maintaining noise rejection capability comparable to existing methods — a capability absent in all prior multi-source RAG frameworks.

Future work will explore three directions: (1) extending the framework to other planetary bodies (Moon, Venus, icy moons) and validating the generalizability of the scale-curvature correspondence and conflict triage principles across different observation ecosystems; (2) incorporating multimodal retrieval that directly reasons over raw imagery and spectral data rather than metadata-derived knowledge graphs, leveraging vision-language models for planetary scene understanding; and (3) developing an interactive planetary data exploration system that integrates AreoRAG with GIS visualization, enabling scientists to conduct natural language-driven, conflict-aware, multi-scale spatial analysis over the full planetary data archive.
