Mars is full of toxic perchlorates that can be very harmful for future human missions. So, when people go to Mars, they will need to fix it. NASA has awarded a NIAC grant for a project that can help solving this problem. It's called Detoxifying Mars: the biocatalytic elimination of omnipresent perchlorates.
