Expedition 73 has ended and NASA astronaut Jonny Kim has returned to Houston and Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky have returned to Moscow. The trio is now readapting to Earth's gravity after living aboard the International Space Station in weightlessness for 245 days.

Expedition 74 is now underway with veteran NASA astronaut Mike Fincke as commander leading six flight engineers including NASA astronauts Zena Cardman and Chris Williams, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonauts Oleg Platonov, Sergey Kud-Sverchkov and Sergei Mikaev.

Fincke spent his Wednesday primarily inside the Tranquility module replacing orbital plumbing components on the waste and hygiene compartment, the station's restroom. The veteran astronaut also prepared cargo and life support racks for removal and reinstallation throughout the orbital outpost's U.S. segment. The rack transfer work will continue into next week.

Cardman processed stem cell samples for stowage in a science freezer ahead of their return to Earth next year for a study demonstrating on-orbit pharmaceutical manufacturing and regenerative medicine. She also measured air flow throughout the U.S. modules and printed out an updated spacewalking checklist.

Williams exercised for research while pedaling on the Destiny laboratory module exercise cycle. He worked out wearing breathing gear and electrodes measuring his aerobic output and cardiovascular health. Afterward, he powered on a fluorescent research microscope then collected carbon dioxide waste samples from an atmospheric cleaner for analysis.

Yui reviewed the rack removal and replacement steps that he Cardman and Williams will assist Fincke with over the next several days. He then worked inside the Kibo laboratory module servicing an experimental carbon  dioxide removal device.

Flight Engineers Kud-Sverchkov and Mikaev, who have been aboard the station with Williams since Nov. 27, had a light duty day on Wednesday with some time set aside for photographic inspections and Elektron oxygen generator maintenance. Flight Engineer Oleg Platonov began his shift on orbital plumbing tasks in the station's Roscosmos segment. Next, he assisted Mikaev with the Elektron job then wrapped up his shift installing hardware that enables the European robotic arm to be remotely controlled from Earth.

Экспедиция 73 завершилась, астронавт NASA Джонни Ким вернулся в Хьюстон, а космонавты Роскосмоса Сергей Рыжиков и Алексей Зубрицкий вернулись в Москву. Троица сейчас восстанавливается к гравитации Земли после 245 дней невесомости на борту Международной космической станции.

Бортинженеры Кудь-Сверчков и Микаев, которые находятся на борту станции вместе с Уильямсом с 27 ноября, в среду были освобождены от тяжёлых работ и могли уделить время фотоинспекции и обслуживанию кислородного генератора «Электрон». Бортинженер Олег Платонов начал свою смену с орбитальных работ по водоснабжению в сегменте станции, принадлежащем Роскосмосу. Затем он помог Микаеву с «Электроном», а в завершение смены установил оборудование, позволяющее дистанционно управлять европейским роботизированным манипулятором с Земли.

Stem cells, materials research, and a technology demo topped the research schedule for the Expedition 74 crew on Thursday. The seven International Space Station residents also worked on a host of lab maintenance including Japanese cargo operations and preparations for upcoming rack transfers.
NASA Flight Engineer Zena Cardman kicked off her day inside the Destiny laboratory module peering at stem cells through a microscope for the StemCellEx-IP1 investigation. She was helping investigators demonstrate the successful production of stem cells in space that are superior to those manufactured on Earth. Results may also advance regenerative medicine for damaged organs and tissues. Later she swapped a gas analyzer, that scans the station's atmosphere for nitrogen, carbon dioxide, and more, inside the Tranquility module.
JAXA (Japan Aerospace Exploration Agency) Flight Engineer Kimiya Yui began his shift installing a materials exposure experiment inside the Kibo laboratory module's airlock. The research hardware will be placed in the vacuum of space exposing a variety of materials to space radiation, extreme temperature changes, and more to benefit a range of Earth and space industries. Yui then installed an experimental carbon dioxide removal device in Kibo and wrapped it with soundproof insulation to reduce noise during its operation. The advanced hardware is being studied to inform advanced life support systems for Artemis lunar spacecraft.
NASA Flight Engineer Chris Williams, with a little bit of assistance from Cardman and Yui, spent most of his shift loading cargo inside JAXA's HTV-X1 that is due to leave the station's Earth-facing port on the Harmony module in late January. He also had time set aside to replace an air filter, turn on a fluorescent microscope, and swap out hardware on a portable computer tablet.
Station Commander Mike Fincke of NASA spent his shift deconfiguring and removing hardware from a science rack that will soon be transferred inside the HTV-X1. Shortly after waking up, Fincke took a test for an experiment documenting how crews sleep while living off the Earth and without the normal day-night cycle, also called circadian rhythm. Afterward, he performed a leak check on a recycle tank inside Tranquility.
Roscosmos cosmonaut Oleg Platonov started his shift measuring his mass attaching himself to a device that applies a known force with the resulting force providing an output using a form of Newton's Second Law of Motion. Platonov then worked throughout the day on life support maintenance, inspecting cables, and uninstalling hardware that provides functionality to the European robotic arm.
Cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, who have been aboard the station since Nov. 27 with Williams, worked throughout the day on a variety of life support maintenance tasks. At the end of his shift, Kud-Sverchkov later installed Earth observation hardware programmed to automatically landmarks on the ground during the crew's sleep shift. Mikaev wiped down surfaces inside the Roscosmos modules to prevent microbial growth.

Космонавт Роскосмоса Олег Платонов начал свою смену, измеряя свою массу, прикрепившись к устройству, которое применяет известную силу, а исходящая сила обеспечивает выход по форме Второго закона движения Ньютона. Платонов затем весь день занимался обслуживанием жизнеобеспечения, проверкой кабелей и демонтажем оборудования, которое обеспечивает функциональность европейской роботизированной руки.

Космонавты Сергей Куд-Сверчков и Сергей Микаев, находившиеся на станции с 27 ноября вместе с Уильямсом, работали весь день над различными задачами по техническому обслуживанию жизнеобеспечения. В конце смены Куд-Сверчков установил оборудование для наблюдения Земли, запрограммированное автоматически определять ориентиры на земле во время сна экипажа. Микаев протёр поверхности внутри модулей Роскосмоса, чтобы предотвратить рост микробов.
