On April 28, 2023, US astronaut Stephen Bowen and UAE’s astronaut Sultan Al Neyadi performed the spacewalk to lay cables for the 1A and 1B power channel iROSA upgrades. 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 EVA lasted 7 hours and 1 minute. It was the 8^th EVA for Stephen Bowen and the 1^st spacewalk for Sultan Al Neyadi.
