These include not only observations of Opportunity, Spirit and Curiosity, but also interpretations of Martian surface geological changes observed by imaging Martian orbiters, and probable life traces found in meteorites, too. When we put Martian terraformation into perspective today, we must already take into account all the biosignatures of the ancient Martian life. There are several organizational levels of biology where signatures of early life on Earth has been observed. In this paper our first approach is to collect and interprete the biosignatures arranged according to the system governed by structural hierarchy of organizational levels of living beings. Although it is difficult to realize the joint existence of several observations at different levels of hierarchy (isotopes, molecules, minerals, microscopic texture) only those data systems give strong evidence of early life, which result from mutually embedded hierarchical structures together. Over terrestrial data, Martian space probe’s datasets about the Martian rocks and surface, the analyses of weathering and mineral transformations of Martian and chondritic meteorites are tools and promisful observational possibilities of early Martian terraformation. On the first place the terrestrial rocks were studied where texture-transformation characteristics of microbial constituents, especially iron bacteria are existing biosignatures on several organizational levels. We found Martian and chondritic meteoritic microtextural counterparts to these terrestrial parallels, illustrating what life forms may have been present in Mars’ past. We have taken this detour from the Martian meteorites to the parallel microbial features of the chondritic meteorites because we believe, that the Martian terraformation may have started very early even on the incoming solar system collisional (meteoritical) debris, originating from earlier (previous to Sun) stellar planetary systems. © 2022 Scrivener Publishing LLC.
