Comparison of NSA and ATP assay in measuring cleanliness of MSL spacecraft accountable-surface samples for 22 out of 272 samples. Swab samples for NSA are represented by circle and wipes are shown in diamonds. Total number of spacecraft flight samples tested by NSA were 272, of which 67 were wipes and 205 were swabs. In total only 22 of the NSA samples exhibited ≥1 spore; the 250 samples that exhibited no spores are not shown. Spore counts (CFU) and ATP values (RLU) of all surfaces are provided as supplementary file (Additional file 1: Table S1)
