Clockwise from left, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui and NASA astronauts Jonny Kim, Zena Cardman, and Mike Fincke pose for a playful portrait through a circular opening in a hatch thermal cover aboard the International Space Station on Sept. 18, 2025.
The cover provides micrometeoroid and orbital debris protection while maintaining cleanliness and pressure integrity in the vestibule between Northrop Grumman’s Cygnus XL cargo spacecraft and the orbital outpost. The opening allows for visual inspection of hatch alignment, access to the hatch handle or pressure equalization valve, and visibility for sensors or cameras during berthing operations.
Kim recently returned to Earth after 245 days in space aboard the orbital laboratory. Yui, Cardman, and Fincke remain aboard the space station, with Fincke as commander.
