New research from Penn State Altoona suggests that Martian soil may naturally suppress Earth-based life. Experiments exposing Tardigrade to simulated regolith show that water-soluble salts inhibit biological activity, though washing the soil reduces toxicity.
The findings reshape planetary protection strategies and reveal a major challenge for future Mars agriculture: extraterrestrial soil may require significant pretreatment before supporting life.
