NASA astronauts have concluded their spacewalk to install modification kits required for upcoming solar panels upgrades.
In the third spacewalk of the year outside the International Space Station, the two astronauts completed the walk in about seven hours.
They worked near the farthest set of existing solar arrays on the station.
To ensure a sufficient power supply for NASA’s exploration technology demonstrations as well as utilization and commercialization, NASA is augmenting six of the eight existing power channels of the space station with new solar arrays. The new solar arrays, a larger version of the Roll-Out Solar Array technology, will be positioned in front of six of the current arrays, ultimately increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts.
