    The International Space Station is orbiting higher today after the Progress 91 cargo craft fired its thrusters for over 17 minutes while docked to the Zvezda service module. The reboost places the orbital outpost at the correct altitude for the arrival of the Soyuz MS-27 spacecraft and its three crew members next week.

    Exercise Research Main Focus Aboard Station on Tuesday

    NASA astronaut and Expedition 72 Flight Engineer Nick Hague exercises on the advanced resistive exercise device (ARED) aboard the International Space Station's Tranquility module. The ARED mimics the inertial forces of lifting free weights on Earth to maintain muscle health during long-term space missions. During his exercise session, Hague wore Bio-Monitor, a garment and headband set outfitted with sensors to collect physiological data and minimally interfere with space station life. Hague wore the garment 48 hours as part of Vascular Aging, a study that monitors an astronaut’s cardiovascular health in space.

    Exercise research was back on the science schedule for the Expedition 72 crew on Tuesday ensuring astronauts stay healthy and in shape while living and working in weightlessness. The International Space Station residents also continued a host of other microgravity research exploring robotics, combustion, and more.

    Wearables, Exercise Research on Station Help Doctors Protect Crews

    Clouds swirl over the Gulf of Alaska and underneath the aurora borealis blanketing Earth's horizon in this photograph from the International Space Station as it orbited 261 miles above.

    Several Expedition 72 crew members began Monday attaching a variety of sensors to themselves and exercising so researchers can see how their bodies are adapting to living and working in microgravity. The International Space Station crewmates also kept up their science maintenance and life support duties at the beginning of the week.

    Cygnus Departs Station After Release from Robotic Arm

    Cygnus is gripped by the Canadarm2

    At 6:55 a.m. EDT, the S.S. Richard “Dick” Scobee Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm, which earlier detached Cygnus from the Earth-facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over the Pacific Ocean.

    Cygnus Departing Station Soon Live on NASA+

    Northrop Grumman's Cygnus space freighter is pictured attached to the Canadarm2 robotic arm ahead of its release from the International Space Station's Unity module. The orbiting lab and Cygnus were soaring into orbital daytime as this photo was taken.

    Live coverage of the departure of the S.S. Richard “Dick” Scobee Northrop Grumman’s uncrewed Cygnus cargo spacecraft from the International Space Station is underway on NASA+, with its release from the robotic arm scheduled for 6:55 a.m. EDT. Coverage will conclude following departure from station.

    Science-Packed Day Advancing Crew Health Before Cargo Mission Ends

    NASA astronaut and Expedition 72 Flight Engineer Anne McClain works on hardware maintenance tasks inside the International Space Station's Kibo laboratory module. Behind McClain is Kibo's airlock where experiment hardware such as external exposure investigations and CubeSats are staged before being placed outside the orbiting lab into the vacuum of space.

    Vision studies, a blood investigation, and more were underway aboard the International Space Station on Wednesday informing scientists how astronauts adapt to long duration spaceflight. The knowledge gained from the ongoing investigations is helping NASA and its international partners protect crews while planning missions to the Moon, Mars, and beyond.

    Exercise Study, Blood Research Top Schedule Ahead of Cargo Missions

    NASA astronaut and Expedition 72 Flight Engineer Nichole Ayers 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.

    Bone, muscle, and blood studies topped the research schedule aboard the International Space Station on Tuesday as the Expedition 72 crew continued exploring how microgravity affects human physiology. The orbital residents are also preparing for cargo missions coming and going at the orbital lab while keeping up life support maintenance.
