ISS Expedition 74: U.S. Spacewalk 94

NASA astronauts will perform a spacewalk outside the International Space Station on Thursday, Jan. 8, 2026.

NASA astronauts Mike Fincke and Zena Cardman will exit the space station's Quest airlock to prepare the 2A power channel for future installation of ISS Roll-Out Solar Arrays (iROSA). Once installed, the array will provide additional power for the orbital laboratory, including critical support of its safe and controlled deorbit.

This spacewalk will be Cardman's first and Fincke's 10th, tying him for the most spacewalks by a NASA astronaut.

U.S. spacewalk 94 will be the 278th EVA in support of the assembly, maintenance and upgrade of the International Space Station. It is also the first International Space Station spacewalk of 2026, and the first by Expedition 74.

NASA is postponing the Thursday, Jan. 8, spacewalk outside the International Space Station. The agency is monitoring a medical concern with a crew member that arose Wednesday afternoon (Jan. 7) aboard the orbital complex.

Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. The situation is stable. NASA will share additional details, including a new date for the upcoming spacewalk, later.
