The EVA lasted 5 hours and 35 minutes. It was the 10^th spacewalk for Steven Bowen and the 2^nd spacewalk for Warren Hoburg.

On June 09, 2023, US astronauts Steven Bowen and Warren Hoburg performed the spacewalk to install an upgraded iROSA (International Space Station Roll-Out Solar Array) on the 1A power channel on the starboard truss of the station. The EVA lasted 6 hours and 3 minutes. It was the 9^th spacewalk for Steven Bowen and the 1^st spacewalk for Warren Hoburg.

On June 5, 2023 at 19:10 UTC (on June 6 Beijing time), the Chinese “Tianzhou-5” unmanned supply spacecraft was docked to the forward docking port of the “Tianhe” core module of the Chinese “Tiangong” space station after more than a month of independent flying. The cargo spacecraft undocked from “Tiangong” on May 05, 2023 to leave room for its successor, “Tianzhou-6”. It had been flying freely for 33 days before the re-docking.
