Household chores, space research conclusion station work week – Space Station

Expedition 68 crew members participate in a conference with ground mission controllers before the astronauts depart from SpaceX Crew-4.

Chores and science ended the week for the Expedition 68 crew aboard the International Space Station. Orbital residents will also see a supply ship leave the orbital lab on Sunday.

NASA flight engineer Frank Rubio spent Friday afternoon rearranging cargo inside the Zarya module to maximize stowage space in the 24-year-old module. Station hardware and other cargo are constantly moved around station modules to support science experiments and maintenance activities. With cargo missions coming and going to the station, it’s necessary for astronauts to keep track of where everything is and keep gear tidy for easy access.

NASA astronaut Nicole Mann spent her day performing orbital plumbing tasks, testing water samples for microbes and inspecting ammonia canisters. Mann has also spent time on human research activities collecting his blood samples, participating in hearing and cognitive testing, and setting up wrist-worn devices that monitor a crew member’s sleep-wake cycle, or rhythm. circadian.

NASA flight engineer Josh Cassada worked throughout Friday maintaining the life support system inside the Harmony and Tranquility modules. Cassada checked the thermal control system components in both modules and collected fluid samples from the life support devices for analysis on Earth. The space flyer for the first time also took part in a standard hearing test.

Working in the laboratory module of Columbus, Japan Aerospace Exploration Agency (JAXA) flight engineer Koichi Wakata recirculated fluids and fed vegetables for the XROOTS space botany study. The Agricultural Survey explores hydroponic and aeroponic methods, soilless techniques, for growing crops in space to keep crews further away from Earth.

Two cosmonauts, flight engineers Anna Kikina and Dmitri Petelin, started Friday morning with a heart search. The duo attached electrodes to monitor their heart bioelectrical activity and understand how microgravity affects their heart function. Kikina then spent the rest of the day on lab maintenance work. Petelin joined Commander Sergey Prokopyev and closed the hatch of the ISS Progress 80 cargo craft before its departure on Sunday, ending an eight-month mission docked to the Poisk module.
