Two astronauts, one from NASA and the other from European State Agency, walk the space to install the solar panels for the power of the space station. It is their second walk this week. The space station faces technical issues in the power supply for many days.
Thus the walk happens to resolve this issue. The walk for the installation of the solar panel lasts 6 hours and began at 8:00 a.m. on Sunday. NASA said that: “Astronauts have connected cables to the space station power supply and unfold the solar array.”
They also make space for the installation of a solar array in the future. The two out of six solar arrays installed for the power supply to the space station are called ISS Roll-out Solar arrays (IROSAs). It helps to provide power supply to six out of eight power channels.
They face many problems that happen on their spacewalk on Wednesday as Kimbrough lost the display of data on his spacesuit. He has to go back to the space station and charged the spacesuit to get it back in its working position. When the astronauts are aligning the solar arrays, one panel was not getting fit in the mold.
The NASA public officer then guides them to fold the panel in a safe configuration for the time being. Because the time was getting wasted, they have to install all panels and two bolts that remained.
Now on Sunday spacewalk, they install the final electrical cables and two bolts that fit in them. That spacewalk is the 240th time walk to maintain, repair, and upgrading the space station. The solar arrays to install in the space station arrived on 5 June, and they rolled up like carpets. Their weight was 340 kilograms and wide 10 feet.
The astronauts then unfurled them in space to install them and weighted 63 meters long and 20 feet wide. The whole process to unfurl them took place for about 6 minutes.
Kimbrough has done the eighth walk of his career, and Pesquet has done the fourth walk in his career.
These new solar arrays have a life span of 15 years long and the crew will check and balance the longevity of these arrays.
