Astronauts wrap up power upgrades spacewalk
Expedition 59 flight engineers Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency concluded their spacewalk on Monday (April 8) at 2 p.m. EDT (1800 GMT).
During the 6 hour, 29 minute spacewalk, the two astronauts successfully established a redundant path of power to the Canadian-built robotic arm, known as Canadarm2, and installed cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability.
The duo also relocated an adapter plate from the first spacewalk in preparation for future battery upgrade operations.
Saint-Jacques ran into an issue installing a fitting for a commercial payload platform outside the European Columbus module and took photos to assist in the troubleshooting and replanning for a future spacewalk.
Space station crew members have conducted 216 spacewalks in support of assembly and maintenance of the International Space Station, spending a total of 56 days, 10 hours and 53 minutes working outside of the orbiting laboratory.
