The detection of life beyond Earth forms the main goal of astrobiology, and a significant one for space exploration in general. This goal has galvanized and connected with other critical areas of investigation such as the analysis of meteorites and early Earth geological and biological systems, materials gathered by samp","authors_text":"Akihiko Yamagishi, Andrew Steele, Chaitanya Giri, Christopher Carr, Cornelia Meinert, Dhananjay Bodas, Hidenori Genda, Hikaru Yabuta, H.
