Power Leap: NASA Spacewalkers Successfully Install New Solar Array on ISS — NASA astronauts Steve Bowe |
Bowen and Hoburg completed all of their objectives to install an IROSA to augment power generation for the 1A power channel on the station’s starboard truss structure. The crew members also completed several get-ahead tasks setting the stage for the duo to go back outside Thursday, June 15, to install the sixth in the series of IROSAs on the starboard 6 truss of the station for the 1B power channel.
The new arrays are 60 feet long by 20 feet wide and will shade a little more than half of the original arrays, which are 112 feet long by 39 feet wide. Each new IROSA will produce more than 20 kilowatts of electricity, and once all are installed, will enable a 30% increase in power production over the station’s current arrays.in support of space station assembly, upgrades, and maintenance, and was the third spacewalk for both astronauts.
Bowen and Hoburg are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASA’s Artemis program.
