Space Environment Survivability of Living Organisms (SESLO) results 14 days post-launch. Germination and metabolism of Bacillus subtilis strain 168 (A) and WN1087 (B). Flight (FL) and Ground Control (GC) samples are denoted by circles and squares, respectively. Symbol colors: blue symbols denote blue (oxidized) form of aB, measured at 615 nm; magenta symbols denote pink (reduced) form of aB, measured at 525 nm; gray symbols denote (mostly) optical density, measured at 470 nm. Results shown are the averages of six separate wells for each strain. Error bars have been omitted for clarity but are presented as standard deviations of the mean in the datasets deposited in the NASA Life Science Data Archive (LSDA).
