Figure 3.

Time course of survival of D. radiodurans R1 exposed to space at UV >170 nm (pale blue triangles) or UV >110 nm (pink triangles), or kept in the dark (pale blue squares). The ISS cabin upper (blue circles), lower (blue squares), and the ground upper (brown circles) and lower (brown squares) controls are also shown. Data of upper plate samples are connected by dotted lines. Data of lower plate samples are shown in squares and connected by dashed lines. The data of 1,000-μm thick samples are shown. The actual thicknesses of the samples are presented in Supplementary Table 1. Each mark shows the mean of triplicate samples; SEM was small and covered by data markers.
