NASA astronaut Nicole Mann and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata began a spacewalk at 8:14 a.m. EST to complete the installation of two mounting platforms as part of planned solar array augmentation on the starboard side of the space station’s truss. The duo will complete the installation of a mounting platform on the 1B power channel that was started during a previous spacewalk, and begin installing a mounting platform on the 1A power channel.

The installation is part of a series of spacewalks to augment the International Space Station’s power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four iROSAs have been installed so far, and two more will be mounted to the platforms installed during this spacewalk in the future.

Mann, designated as extravehicular crew member 2 (EV 2), is wearing an unmarked suit. Wakata, designated as extravehicular crew member 1 (EV 1), is wearing a suit with red stripes. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.
