Framtida Marsmissioner bör fokusera på direkt detektering av mikrobiell aktivitet under ytan, inte bara kartläggning av potentiell habitabilitet. Forskare från UCLA, Caltech och University of Edinburgh argumenterar att metodiska framsteg inom subsurfacebiologi nu möjliggör agnostisk livsdetektering genom mätning av mikrobiell metabolism och biokemiska markörer. På Mars bevaras dessa biosignaturer bättre under ytan än på den strålningsexponerade ytan. Tidigare Vikinguppdrag gav tvetydiga resultat från direkta livstest, vilket skiftade fokus mot habitatanalys. Jordens subsurfaceystudier har visat att habitabla miljöer inte nödvändigtvis innehåller liv, men att metabolism är en bred tillämplig livindikator. För leverantörer av instrumentering och uppdragsplanering blir detta relevant: subsurfacesampling och metabol detektering blir prioriterade teknologier för nästa explorationsfas, vilket påverkar instrumentsval och projektplanering framöver.
