ALT NASA astronauts Chris Williams and Jessica Meir, both Expedition 74 flight engineers, inspect and configure a spacesuit jetpack, known as the Simplified Aid for EVA Rescue (SAFER), inside the International Space Station’s Destiny laboratory module. The jetpacks attach to the rear of spacesuits and serve as a safety mechanism that allows a spacewalker to maneuver back to the station in the unlikely event they become untethered from their worksite.
ALT NASA astronaut Chris Williams is pictured outside the International Space Station during a spacewalk to complete the build and installation of a modification kit ahead of future solar array installation on the 2A power channel of the space station. It was William’s first spacewalk of his career, and the 278th in support of space station maintenance, upgrades, and assembly.

ALT NASA astronaut Jack Hathaway loads bacterial samples into a portable DNA sequencer to read their genetic code inside the International Space Station’s Harmony module. The GEARS biotechnology investigation may help scientists understand how bacteria become resistant to antibiotics in the space environment, which could affect an astronaut’s ability to fight infections.

ALT Flight engineer Sophie Adenot of ESA (European Space Agency) assists flight engineer Chris Williams of NASA as he tries on his spacesuit, testing its comfort and mobility as well as its communications and life support systems inside the International Space Station’s Quest airlock. Williams was preparing for a spacewalk to replace a malfunctioning wrist joint on the Canadarm2 robotic arm, planned for June 30, 2026.

ALT NASA astronaut and Expedition 74 flight engineer Jessica Meir works inside the Kibo laboratory module's Life Science Glovebox setting up research hardware for a blood stem cell investigation. Meir would later nourish the stem cells that are growing inside a research incubator to help doctors learn how to manufacture and commercialize space-designed therapies for a variety of blood cancers and immune diseases.
