Introduction: The Search for Life on Mars
Mars is the most intensively studied world in the Solar System in humanity’s quest to determine whether life exists beyond Earth. Its ancient evidence for liquid water, diverse geological environments, and detectable organic compounds make it a leading target for astrobiology. Life detection involves identifying robust biosignatures—features that can only be explained by biology. The scientific challenge is to distinguish these from abiotic (non‑life) chemical and geological processes, which often produce similar signals.
