The Earth begins illuminating during an orbital sunrise as spacewalkers Sultan Alneyadi and Stephen Bowen work outside the space station. Credit: NASA TV’s Steve Bowen and UAE’s Sultan Alneyadi successfully completed a 7-hour spacewalk to prepare for the installation of new solar arrays on the ISS. Despite a delayed operation to free a degraded communications antenna, the mission marked the 261st spacewalk for the ISS and a first for a UAE astronaut.
Bowen and Alneyadi laid cables and installed insulation on mounting brackets on the starboard truss of the station for the installation of the next pair ofRoll Out Solar Arrays . The astronauts were unable to free up an electronics box located on the truss associated with a degraded S-band communications antenna. The antenna removal was deferred to a future spacewalk ahead of its planned return to Earth.
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 . Four iROSAs have been installed so far, and two more will be mounted to the platforms installed during this spacewalk in the future.
