The seven-member Expedition 65 crew kicked off the workweek working on Japanese science gear, a U.S. immune system study, and spacewalk preparations.

Flight Engineers Mark Vande Hei and Thomas Pesquet joined station Commander Akihiko Hoshide for science maintenance in the Kibo laboratory module on Monday morning. The trio teamed up and installed an experiment platform in Kibo’s airlock, where it will soon be placed outside in the harsh environment of space.

Vande Hei then moved on and serviced donor cell samples for the Celestial Immunity study taking place inside the Kibo lab’s Life Sciences Glovebox (LSG). The experiment looks at cells launched to space and compares them to cell samples harvested on Earth to document the differences in weightlessness. Results could impact the development of new vaccines and drugs to treat diseases on Earth and advance the commercialization of space.

Pesquet later took photographs of U.S. spacesuit gloves for inspection ahead of two spacewalks planned for June. During those spacewalks, new solar arrays will be installed on the station’s Port 6 truss structure to augment the station’s power system. The first two of six new solar arrays will be delivered on the next SpaceX cargo mission planned for launch on June 3 from NASA’s Kennedy Space Center.

Hoshide checked power cables on the Confocal Space Microscope that provides fluorescence imagery of biological samples. Then he took turns with NASA Flight Engineer Shane Kimbrough, participating in a computerized cognitive assessment. Next, Kimbrough worked the rest of Monday in the Tranquility module’s Water Processing Assembly to repair a possible leak.

NASA Flight Engineer Megan McArthur opened up BEAM, or the Bigelow Expandable Activity Module, and organized cargo during the morning. She then powered down and stowed the LSG after Vande Hei concluded Monday’s immunity research.

Cosmonauts Oleg Novitskiy and Pyotr Dubrov spent the morning organizing Russian spacewalk tools. Afterward, the duo spent the rest of the day working on communications gear and ventilation systems.

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
