If any kind of life exists on Mars it would have to be unlike anything here. Mars is bathed in peroxides and a whole spectrum of ionizing radation with little to no magnetic field to protect it. https://www.ncbi.nlm.nih.gov/pubmed/11537371 https://www.ncbi.nlm.nih.gov/pubmed/11537371
- simonh 9y agoThere are many organisms that can tolerate those concentrations of peroxides, and others that can tolerate the radiation exposure aside from the fact that a few inches of soil provides fairly decent protection anyway. From your link: "These results indicate that it is doubtful that the presence of H2O2 alone on Mars would make the surface "self-sterilizing"."
- ohiovr 9y agoSorry about that, this link from nature is a better angle to the problem (I forgot about perchlorates on Mars). https://www.nature.com/articles/s41598-017-04910-3 https://www.nature.com/articles/s41598-017-04910-3 looks pretty brutal up there
