Teanna, Carlos and Ian along with collaborators from Canada, China, Mexico and Türkiye published a study in Astrobiology that examined the environmental and mineralogical controls on biosignature preservation in magnesium carbonate systems analogous to Jezero Crater, Mar. Our article was featured on the cover of Astrobiology! This micrograph is of a microbialite composed of aragonite from the Mg-carbonate playas near Atlin, Canada, a terrestrial analogue for Jezero Crater, and shows the entombment of diatoms frustules and filamentous cyanobacteria. This study contributes to our knowledge of terrestrial analogues to Mars environments and may aid in prioritizing sample collect for later return missions to Earth.
