Following the discovery of the first organism, “Wurm,” in the shallow soil subsurface on Mars, intense interest has evolved to attempt to understand the diversity of organisms living in these extreme environments. We concluded that Wurm and Arthropoda, are organisms thriving at 1.5 – 3.0 inch depths in palaeometeoric fissures which are estimated to be 3,500,000,000 – 4,000,000,000 years old.
Protozoan and other organisms have been identified; however, they are present in low numbers in this captured Mars rover picture. Characterization of the newly found different species on Mars reveals that many are opportunistic organisms with an unknown origin due to recharge from the surface waters rather than soil leaching. This is the first known study to demonstrate the in situ distribution of organisms in the fracture and fissure soil using picture documentation directly from NASA. The discovery of a new group of organisms underground on Mars has important implications for the search for life on other planets in the solar system.
