    Expedition 73 Studies How Space Affects the Brain and the Body

    The warm city lights of Southeast Asia streak below the silvery U.S. segment of the International Space Station in this 30-second exposure from the orbital outpost as it soared 259 miles above China at approximately 10:39 a.m. local time. Near the top center, is the partially obscured SpaceX Dragon spacecraft that docked to the Harmony module's forward port carrying NASA's Crew-11 mission.

    Maintaining sense of balance and protecting immunity in space were the top human research experiments aboard the International Space Station on Wednesday. The Expedition 73 crew members also practiced medical emergency procedures, continued more Earth observations, and finished packing a cargo craft.

    Health Monitoring, Exercise Science Keep Station Crew Busy

    NASA astronaut and Expedition 73 Flight Engineer Mike Fincke inserts a cryogenic storage unit, called a dewar, containing blood samples collected from a crew member into a science freezer for preservation and later analysis. The Minus Eighty-Degree Laboratory Freezer for International Space Station, or MELFI, is a research freezer that maintains experiment samples at ultra-cold temperatures in microgravity.

    Immunity and exercise science continued aboard the International Space Station on Wednesday giving doctors insight into how the human body adjusts to weightlessness. The Expedition 73 crew is also packing a cargo craft before the end of its mission and maintaining a variety of orbital lab hardware.

    Crew Sets Up Space Hardware to Make Fiber Optics and Brew Lunar Sake

    The International Space Station soars 259 miles above Cambodia in this long-duration photograph revealing star trails, lightning storms, and the city lights of Southeast Asia streaking below.

    Fiber manufacturing and lunar brewing wrapped up the research week aboard the International Space Station helping NASA and its international partners promote the commercialization of space. The Expedition 73 crew also continued its space biology studies to keep astronauts healthy while packing a resupply ship for its upcoming departure and maintaining life support systems.

    Crew Tackles Cardiac Research, Cargo Ops, and Spacesuit Checks

    A vivid red and green aurora crowns Earth’s horizon over the southern Indian Ocean in this photo from the International Space Station as it orbited 270 miles above. At top left, a lit window reveals the docked SpaceX Dragon crew spacecraft docked to the orbital outpost's forward port on the Harmony module, set against a starry sky captured with long-exposure, low-light settings.

    Heart and blood pressure studies led the research schedule for the Expedition 73 crew on Wednesday informing scientists how the cardiovascular system adapts to weightlessness. The International Space Station residents are also gearing up for the next SpaceX Dragon cargo mission and cleaning spacesuits for potential spacewalks later this year.

    Station Crew Tracks Changes to Eyes, Brain, and Blood in Space

    NASA astronaut and Expedition 73 Flight Engineer Jonny Kim stows research samples inside a cryogenic storage unit for installation inside a science freezer for preservation inside the International Space Station's Destiny laboratory module. Offically called the Minus Eighty-Degree Laboratory Freezer for ISS, or MELFI, the ultra-cold storage unit enables space biology research by preserving biological samples for analysis including blood, saliva, urine, microbes, and more.

    More human research was underway aboard the International Space Station on Tuesday as the Expedition 73 crew explored how working in space affects the eyes, brain, circulatory system, and more. Quantum physics hardware and spacesuit maintenance rounded out the schedule for the seven orbital residents.
