Astronaut Works Spacesuits as Cygnus Burns Up for Science

Commander Jeff Williams continued the ongoing maintenance on U.S. spacesuits throughout the workday on Wednesday. Meanwhile, the Cygnus cargo craft from Orbital ATK re-entered the Earth’s atmosphere completing one final experiment.
Williams scrubbed cooling loops and collected water samples from inside U.S. spacesuits ahead of a pair of spacewalks planned for later this year. The main task planned for the first spacewalk will be installing an international docking adapter to the Harmony module. The second spacewalk will see the replacement of batteries as part of maintenance for the International Space Station’s power system.
Cygnus has been busy since its release from the station June 14 serving as a platform for science. Its first experiment saw a large fire set inside the vehicle helping scientists understand combustion in space. Earlier this week, a set of nanosatellites was released from Cygnus. Finally, as Cygnus broke apart during its re-entry recorders downlinked data providing insights into the behavior of spacecraft re-entering Earth’s atmosphere.
