Products: lunar-lander, rover. Risk band: Elevated RobotRisk index 24.2/100 (incidents/exposure, time-weighted) · 97th percentile of 118 defense space companies.
The register carries a single entry for JAXA: a December 2025 H3 rocket failure during launch of a navigation satellite, coded mission-loss with a severity of 4. One event places the agency at the 98.3rd percentile of its defense-space peer set with an elevated index of 24.4, reflecting the high severity weight assigned to a launch failure rather than a pattern of repeated incidents. The record is press-driven, anchored to a single dated launch event rather than an accumulation of regulatory findings. No trajectory can be established from one data point; the standing here is a function of severity and category concentration, not frequency.
