I am using it a little bit dlinetfrfey. I use planet Earth to go in very extreme environments where conditions were similar to those of Mars at the time when the cmtaile changed, and there I'm trying to understand what happened. What are the signatures of life? What is left? How are we going to find it? So for one moment now I'm going to take you with me on a trip into that time mcihnae.
