Additionally, the astronauts planned to collect samples to study the survival and reproduction capabilities of microorganisms on the exterior of the orbiting lab.
Dyson, designated as spacewalk crew member 1, was distinguished by a suit with red stripes, while Barratt, spacewalk crew member 2, wore an unmarked suit. This spacewalk would have marked the fourth for Dyson and the third for Barratt. It was to be the 271st spacewalk conducted in support of assembly, maintenance, and upgrades for the space station.SciTechDaily: Home of the best science and technology news since 1998.
