Astronauts Install Solar Array Mod Kit, Complete Spacewalk Editor’s Note: This blog was updated on March 19, 2026, to correct the completed and deferred tasks for U.S. spacewalk 94. NASA astronauts Jessica Meir and Chris Williams concluded their spacewalk outside the International Space Station at 3:54 p.
m. EDT. It was Williams’ first spacewalk and Meir’s fourth. During the approximately seven-hour and two-minute spacewalk, Meir and Williams completed their primary objectives, which included preparing the 2A power channel. This work will enable the future installation of roll-out solar arrays to provide additional power for the orbiting laboratory, supporting critical systems and its safe, controlled deorbit. The duo also completed additional tasks, including installing a 2A power system jumper cable. The remaining tasks, including installing a lens cover on a camera attached to the station’s Canadarm2 robotic arm and swabbing for microorganisms near the Quest airlock, will be moved to a future spacewalk.
