Detoxifying Water on Planet Mars | NASA Space Technology

Great news for human space exploration! Scientists have confirmed there is frozen water on Mars but there remians a major challenge. Martian water is full of toxic chemicals called perchlorates. Molecules of chlorine mix in with the upper Martian soil, contaminating water that is present there. These chemicals are harmful to humans and corrode equipment. Before humans could use this water, these toxins must be removed. 

However, the amount of water needed for long-term stays on Mars makes traditional approaches impractical. Thus, a team of NASA researchers is developing a new solution that uses biology instead of chemistry to detoxify the water. The proposed bioreactor would use specially engineered bacteria to clean the water and turn the contaminants into consumables. The process is sustainable, scalable, and would eliminate the need to dump the waste material somewhere else. This clean water could be used for irrigation, human hydration, and propellent production. This concept could help sustain a human presence on Mars and may lead to improved water purification solutions here on Earth.

This video represents a research study within the NASA Innovative Advanced Concepts (NIAC) program. NIAC is a visionary and far-reaching aerospace program, one that has the potential to create breakthrough technologies for possible future space missions. However, such early-stage technology developments may never become actual NASA missions.
