Non-metric multidimensional scaling (NMDS) ordination plots, based on Bray-Curtis (Panel A) or Unweighted Unifrac (Panel B) distances between samples obtained from the International Space Station and samples obtained from homes on Earth. In these plots, points that are closer together have more similar microbial communities. Note, the crew and lab vent samples that are distinct from the other ISS samples Figure MNDS_ISS_only, do not cluster with any of the Earth home surfaces. This graph was produced using the Phyloseq package \cite{McMurdie_2013}  in R (McMurdie 2013)(R-project 2014). \cite{R}
