Expedition 73 Crew Celebrates International Space Station's 25th Anniversary

Expedition 73 Crew Celebrates International Space Station's 25th Anniversary

The seven-member Expedition 73 crew poses for a portrait commemorating 25 years of continuous human presence aboard the International Space Station. In the front row from left are, NASA astronaut Jonny Kim, Roscosmos cosmonaut and station Commander Sergey Ryzhiokov (Russia), and Roscosmos cosmonaut Alexey Zubritsky (Russia). In the back row are, Roscosmos cosmonaut Oleg Platonov (Russia), NASA astronauts Mike Fincke and Zena Cardman, and the Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui.
All seven members of the Expedition 73 crew gather for a portrait during dinnertime at the galley inside the International Space Station’s Unity module. In the foreground, holding the camera for a group selfie, is Roscosmos cosmonaut Alexey Zubritsky (Russia). In the back, from left, are the Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui, NASA astronaut Mike Fincke, Roscosmos cosmonaut and station commander Sergey Ryzhikov (Russia), NASA astronauts Jonny Kim and Zena Cardman, and Roscosmos cosmonaut Oleg Platonov (Russia).

NASA astronaut and Expedition 73 Flight Engineer Mike Fincke gives a “thumbs up” while holding a High Definition Extravehicular Mobility Unit Camera, or HECA. The spacesuit helmet-mounted camera streams real-time, high-definition video of spacewalk activities to mission controllers on the ground.

Japan Aerospace Exploration Agency (JAXA) astronaut and Expedition 73 Flight Engineer Kimiya Yui shows off production bags containing bioengineered yeasts and probiotic cultures for the BioNutrients-3 investigation. Yui conducted passaging and straw tests to demonstrate how astronauts could grow and safely consume fresh vitamins and nutrients on demand helping researchers plan future missions farther from Earth.
NASA astronauts Zena Cardman and Jonny Kim, both Expedition 73 flight engineers, pose for a fun portrait inside the International Space Station’s Unity module shortly after the arrival of Northrop Grumman’s Cygnus XL cargo craft. The duo had just begun unpacking several tons of new science experiments, supplies, and hardware.

International Space Station - 25 Years in Orbit (2000-2025)
An international partnership of space agencies provides and operates the elements of the International Space Station (ISS). The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada.

The station was designed between 1984 and 1993. Elements of the station were under construction throughout the US, Canada, Japan, and Europe beginning in the late 1980s.

The International Space Station Program brings together international flight crews, multiple launch vehicles, globally distributed launch and flight operations, training, engineering, and development facilities, communications networks, and the international scientific research community.
