Tuesday aboard the International Space Station was packed with human research activities helping doctors understand how the Expedition 65 crew is adapting to microgravity. Meanwhile, preparations are ramping up for a Russian spacewalk scheduled for next week.

Four astronauts took turns during the afternoon using the Ultrasound 2 device for artery scans. NASA Flight Engineer Megan McArthur kicked off the biomedical investigation today and scanned Commander Akihiko Hoshide’s neck, clavicle, shoulder and leg arteries in the Columbus laboratory module. Next up, astronauts Thomas Pesquet and Shane Kimbrough took turns as they participated in the ultrasound scanning activities.

McArthur started her day swapping fuel bottles inside the Combustion Integrated Rack before readying a science freezer for a new animal-microbe study due to be delivered on the next SpaceX Cargo Dragon mission. Kimbrough also spent some time setting up Plant Water Management hardware inside the Harmony module for ongoing botany research.

The Celestial Immunity study is still under way aboard the orbital lab as researchers compare donor cells recently launched to the station with those harvested on Earth. NASA Flight Engineer Mark Vande Hei serviced the cell samples inside the Life Science Glovebox possibly helping scientists develop new vaccines and drugs for diseases on Earth.

Four members of the Expedition 65 crew, who rode to the station aboard the Space Crew Dragon Endeavour, also joined up for an emergency drill before lunch today. Kimbrough, McArthur, Pesquet and Hoshide practiced cardiopulmonary resuscitation (CPR), reviewed medical hardware, and rehearsed communication and coordination procedures.

The sixth spacewalk of the year is set for June 2. Cosmonauts Oleg Novitskiy and Pyotr Dubrov will open the hatch to the Poisk module at 1:20 a.m. EDT  and exit into the vacuum of space wearing their Orlan spacesuits. NASA TV will begin its live coverage at 1 a.m. of the six-and-a-half hour spacewalk for Russian hardware maintenance and science experiment installations.

The Expedition 63 crew started the workweek checking out hardware supporting life science, combustion research and ongoing Earth observations. A Russian cargo craft docked to the International Space Station is also being packed with old gear for disposal toward the end of the year. The multitude of microgravity research that takes place every day on the orbiting lab, requires regular maintenance and monitoring by the crew or scientists on the ground. The ongoing research supports innovative applications and insights benefitting Earth and space industries. Today, Commander Chris Cassidy serviced an advanced space microscope and swapped components supporting safe combustion investigations. Cassidy first configured the Light Microscopy Module , part of the Fluids Integrated Rack , which supports basic physics and biology research. Next, the veteran N

Thursday’s science schedule aboard the International Space Station focused primarily on DNA and physics research including ongoing Earth photography sessions. The Expedition 63 trio also maintained life support gear and packed a Russian cargo ship. The space environment affects a variety of biological and physical phenomena adapted and designed for Earth’s gravity and atmosphere. Organisms from microbes to humans experience a variety of critical changes in microgravity. Fuels, materials and a host of other physical conditions also go through a series of important modifications. NASA and its international partners study these effects to ensure the health of astronauts and safety of spacecraft planned for future missions to the Moon, Mars and beyond. DNA studies have been ongoing for years on the station to understand

Credit: NASA TV At 4:38 a.m. EST, Expedition 64  Flight Engineer Soichi Noguchi of the Japanese Aerospace Exploration Agency used the International Space Station’s robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as Flight Engineer Michael Hopkins of NASA monitored Cygnus systems during its approach. Next, ground controllers will command the station’s arm to rotate and install Cygnus, dubbed the S.S.  Katherine Johnson , on the Earth-facing port of the station’s Unity module . NASA Television coverage of installation will begin at 6 a.m., and installation of the Cygnus spacecraft to the space station is expected to be completed later this morning. Cygnus will remain at the orbiting laboratory for a three-month stay. Watch live on the agency’s website or on the NASA app. Learn more about space station activi
