Key Evidence for a Habitable Early Mars
NASA rovers have found minerals and rock textures that form in water, suggesting lakes and rivers existed long ago. ESA's Trace Gas Orbiter has studied methane variations, and NASA's Curiosity rover has detected organic compounds in Martian samples.

Current Missions Searching for Biosignatures
NASA's Perseverance rover is collecting rock samples in Jezero Crater for a future return to Earth. ESA's ExoMars Rosalind Franklin rover is designed to drill deeper and analyze subsurface material. These missions aim to test whether Mars past life left detectable traces in the planet's geology.
