AstroReason-Bench - Revisit Optimization - Mapping Coverage: leaderboard

AstroReason-Bench (Wang et al., Fudan University, 2026) has LLM agents plan satellite operations in a physics-grounded simulator (orbit propagation, slewing, power and onboard storage) through tools and a Python API, all in the same Claude Code agent loop, over a four-day horizon. In the revisit task a constellation must keep observing monitoring targets while filling observation quotas for mapping targets; this board scores the mapping side as the percentage of quotas fulfilled, averaged over five generated cases. Higher is better.

Metric: Mapping-quota coverage (%; one run of five procedurally generated cases, Claude Code ReAct harness). Source: arxiv.org. Saturation forecast: Estimated already saturated. 6 models tracked.
