2 NASA astronauts to complete first spacewalk of 2026 outside International Space Station

Two NASA astronauts aboard the International Space Station (ISS) will complete a spacewalk on Thursday morning to make preparations for future technology installation.

NASA said astronauts Mike Fincke and Zena Cardman will be the ones doing the spacewalk. The space agency said it's Fincke's tenth spacewalk and Cardman's first.

It's the first spacewalk completed by NASA's Expedition 74.

U.S. Spacewalk 94 will last several hours, beginning at 8 a.m. EST and planned to last until about 2:30 p.m.

During their spacewalk, NASA said Cardman and Fincke will exit the space station's Quest airlock to prepare the 2A power channel for future installation of International Space Station Roll-Out Solar Arrays.

NASA said once installed, the array will provide additional power for the orbital laboratory, including critical support of its safe and controlled de-orbit.

Fincke and Cardman are two of seven astronauts that are part of Expedition 74, which began in early December and will conclude this summer.

U.S. Spacewalk 95 will start at 7:10 a.m. EST and will last about six hours and 30 minutes, as well.

The crew for this spacewalk has yet to be announced.

NASA said the astronauts on this spacewalk will "replace a high-definition camera on camera port 3, install a new navigational aid for visiting spacecraft, called a planar reflector, on the Harmony module’s forward port, and relocate an early ammonia servicer jumper — a flexible hose assembly that connects parts of a fluid system — along with other jumpers on the station’s S6 and S4 truss."
