False Negatives in Biosignature Detection: Challenges, AI-Driven Strategies, and the Geochemical Roadmap
To the point
Detecting life beyond Earth is hard because biosignatures can fade, be hidden, or be erased by planetary chemistry, so we need an open, interdisciplinary approach using lab experiments, computer models, fieldwork, and AI, plus careful landing-site selection and ground-truthing to reduce false negatives and avoid discarding Earth-like life signals.
