Abstract Title: Nitrogen and habitability on Mars: Insights from missions, meteorites, and terrestrial analogs
Abstract Body: Life on Earth evolved metabolic pathways to fix atmospheric nitrogen to more biochemically available molecules for use in proteins and informational polymers. For this reason, “Follow the nitrogen” has been proposed as a strategy in the search for life on Mars. We discuss detections of fixed nitrogen on Mars by the Mars Science Laboratory (MSL) Curiosity Rover, recent evidence of nitrogen-bearing compounds in Martian meteorites, and nitrogen systematics in terrestrial analogs to illuminate the role of nitrogen in the habitability on Mars.
