    Station Preps for Crew Swap and Continues Space Health Studies

    An aurora streams across Earth's horizon in this photograph from the International Space Station as it orbited 266 miles above the Bass Strait off the coast of southeast Australia. At left, a set of the orbital outpost's main solar arrays extend across the frame. At bottom, a portion of the station's U.S. segment is illuminated including the SpaceX Dragon crew spacecraft docked to the Harmony module's forward port in this photograph taken from the cupola at approximately 6:56 p.m. local time.

    The Expedition 73 crew is preparing to split up in early August while another crew on the ground is beginning final preparations for a launch to the International Space Station next week. Meanwhile, the orbital residents continue their human research activities, space exercise studies, and lab maintenance duties on Wednesday.

    Bone and Robotics Research Informing Future Missions as Crew Nears Departure

    City lights sparkle across the southern United States in this photograph taken at approximately 4:44 a.m. local time from the International Space Station is it orbited into a sunrise 260 miles above Florida. In the right foreground, is a set of the orbital outpost's main solar arrays augmented by a smaller set of roll out solar arrays.

    The Expedition 73 crew kicked off the week studying how to live and work in space during long-term missions including staying healthy in weightlessness and operating planetary robots from a spacecraft. The seven International Space Station (ISS) residents also replaced flight hardware and continued preparing for a crew swap beginning at the end of the month.

    Human Research on Station Helping Keep Long Term Crews Healthy

    Expedition 73 Flight Engineer Nichole Ayers of NASA and International Space Station Commander Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) collect blood samples for the Immunity Assay human research investigation. The study will analyze the blood samples for signs of space-caused stress on cellular immune function to help doctors monitor crew health and keeps crews healthy on long term space missions.

    Heart scans, breathing measurements, and a fitness test led the research activities aboard the International Space Station on Thursday giving doctors continuous insight into microgravity’s effect on the human body. The Expedition 73 residents also ensured the advanced science hardware and life support gear remain in tip-top shape aboard the orbital outpost.

    Ax-4 Returns Home; Expedition 73 Studies Space Effects on Heart, Nervous System

    Expedition 73 Flight Engineer Jonny Kim from NASA and Axiom Mission 4 Commander Peggy Whitson work together inside the International Space Station's Destiny laboratory module setting up research hardware to culture patient-derived cancer cells, model their growth in microgravity, and test a state-of-the-art fluorescence microscope. Results may lead to earlier cancer detection methods, development of advanced cancer treatments, and promote future stem cell research in space.

    Axiom Mission 4 (Ax-4) splashed down in the Pacific Ocean at 2:31 a.m. PDT Tuesday ending a 20-day spaceflight that saw the private astronauts perform critical microgravity research aboard the International Space Station. Veteran astronaut Peggy Whitson, who has accumulated 695 days in space over five missions, led Pilot Shubhanshu Shukla and Mission Specialists Sławosz Uznański-Wiśniewski and Tibor Kapu back to Earth aboard the SpaceX Dragon spacecraft.
