Metagenomic read mapping to novel isolates from NASA cleanrooms, highlighting temporal and spatial dynamics. A Spatial distribution of mapped reads across 26 novel species, showing distinct signatures between spore-forming and non-spore-forming bacteria in different NASA cleanroom locations. B Box plots illustrating the breadth of coverage (> 1%) of consensus genomes constructed from mapped reads aligned to 23 novel species (out of 26). Reads were collected from cleanrooms at SAF JPL and KSC-PHSF in 2016 (red) and KSC-PHSF in 2018 (blue)
