NASA astronauts on spacewalk prep space station for new solar array

The International Space Station is now ready for the addition of an upgraded solar array after two NASA astronauts completed a nearly seven-hour spacewalk on Tuesday (March 15).

Expedition 66 crewmates Kayla Barron and Raja Chari secured brackets and erected struts at the base of one of the space station’s eight original power-providing arrays, preparing the area for the future installation of an ISS Roll-Out Solar Array (iROSA). Their work on the S4 channel of the 3A solar wing deployed the support structure for the third of six new arrays and the first to be added to the starboard side of the space station’s backbone truss.
