Search for Evidence of Life, past or present

The quest to understand the potential for life on Mars involves a multifaceted approach, including the study of its atmospheric composition and early Earth-like environments. Researchers focus on acquiring samples, particularly from subsurface and evaporite deposits, which are known to preserve organic molecules and structures.
