NASA reported on Aug. 6, 2026, that astronauts Jessica Meir and Anil Menon were scheduled to leave the International Space Station's Quest airlock for a spacewalk expected to begin at approximately 8:35 a.m. EDT and last about six and a half hours. During the outing, the pair were to prepare the 3B power channel for the future installation of International Space Station Roll-Out Solar Arrays (IROSA).

According to the same report, the solar array was scheduled for delivery later that year and would be the seventh IROSA, providing additional power for critical station operations, including its safe and controlled deorbit. Meir, wearing a suit with red stripes, was assigned as spacewalk crew member 1; Menon, in an unmarked suit, was crew member 2. NASA said the spacewalk would be Menon's first and Meir's sixth, and the 281st in support of station assembly, maintenance and upgrades.
