Expedition 73 Photos—May to July 2025 | International Space Station

NASA astronaut and Expedition 73 Flight Engineer Nichole Ayers stows physics research hardware from inside the Microgravity Science Glovebox located inside the International Space Station's Destiny laboratory module. Ayers was completing operations with the Ring Sheared Drop investigation that may benefit pharmaceutical manufacturing techniques and 3D printing in space.

Roscosmos cosmonaut and Expedition 73 Flight Engineer Sergey Ryzhikov of Russia poses for a playful portrait in the Zvezda service module seemingly holding its treadmill above his head aboard the International Space Station. Ryzhikov was working on treadmill maintenance inspecting, removing, and replacing components on the exercise device.

NASA astronauts Anne McClain, and Nichole Ayers, along with Japan Aerospace Exploration Agency (JAXA) astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov of Russia are now turning their attention to the end of their mission with a return to Earth targeted for early August. Before the Crew-10 quartet leaves, NASA’s SpaceX Crew-11 mission is targeted to launch no earlier than July 31 with Commander Zena Cardman of NASA leading Pilot Mike Fincke of NASA and Mission Specialists Kimiya Yui of JAXA and Oleg Platonov of Roscosmos (Russia).
