What is a roll-out solar array?
The Mission
NASA astronauts Mike Hopkins and Victor Glover stepped outside the International Space Station to begin a spacewalk installing a new roll-out solar array on June 20, 2021. The mission aims to augment the space station’s power capabilities and provide an additional energy source for years to come.
The Installation Process
During the spacewalk, Hopkins and Glover will work to remove the current solar arrays and install the new one. The new arrays, which are set to unfurl like giant party streamers, will be positioned on the station’s far end. The spacewalkers will mount struts and attach a support bracket onto the 750-pound array, which will then be unfurled using stored energy.
The Benefits
Once operational, the new solar array will provide more than 20 kilowatts of power to the International Space Station, enough to power more than half the station’s systems. The array is expected to remain in service for over 15 years, providing the station with additional power and making spacewalks to replace aging solar panels unnecessary.
Conclusion
The installation of the roll-out solar array is a significant and exciting milestone for the international scientific community. Modernizing the space station’s power systems will enable NASA and its partners to continue conducting groundbreaking research and advancements in the field of space exploration. This successful spacewalk installation of the new solar arrays marks a significant step forward in the future of space travel and exploration.
