Water Processor Assembly Restored, Spacewalk Preps, Immunity Research Round “Magical” Day on Station

The station’s Water Processing Assembly (WPA), located in the Tranquility module, was reactivated today and is operating at full functionality after crew members successfully completed repair work throughout the week. The WPA was powered off last week due to a suspected leak.

This hardware is used to recycle water from multiple sources into clean, drinkable water for crew members aboard the International Space Station. The space station serves a vital role in testing and maturing life support technologies that will be required for future missions to the Moon and Mars. Repairs provide invaluable data to engineers refining these systems for use in future spacecraft and missions.

The Expedition 65 crew wrapped up its workweek continuing to research the immune system and preparing for next month’s spacewalk. There was also a bit of magic on the orbital lab today to illustrate the challenges of living in space.

NASA Flight Engineers Mark Vande Hei and Megan McArthur were back on the Celestial Immunity study during Friday afternoon. The duo took turns working in the Life Sciences Glovebox where the experiment takes place. The experiment may help scientists understand how weightlessness affects donor cell samples compared to cell cultures harvested on Earth. Observations may lead to new insights possibly improving vaccines and disease treatments on the ground.

McArthur started her day inside BEAM, the Bigelow Expandable Activity Module, stowing cargo and servicing sensors. She was assisted throughout Friday morning inside the five-year-old module by fellow flight engineers Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency).

Kimbrough spent the first part of the afternoon packing trash for disposal aboard the U.S. Cygnus space freighter. He wrapped up his day in the U.S. Destiny laboratory module swapping samples for a physics study exploring ways to improve the production of semiconductor crystals.

Pesquet spent most of his morning in the Columbus laboratory module videotaping himself performing magic tracks for the Illusion educational study. The experiment sponsored by ESA illustrates how visual perception and the central nervous system is impacted in microgravity.

The next spacewalk at the orbital lab is planned for June 2. The two Roscosmos flight engineers, Oleg Novitskiy and Pyotr Dubrov, will work outside in the vacuum of space for external maintenance and science experiment installations for about six-and-a-half hours. The duo spent most of Friday getting their spacewalking tools and Orlan spacesuits ready for their first career excursions.

Station Lifts Orbit as Crew Works Biology and Spacewalk Preps

The International Space Station raised its orbit today to get ready for an upcoming Russian resupply mission due to launch at the end of June. Meanwhile, the Expedition 65 crew continued its biology studies, spacewalk preparations and orbital lab maintenance on Thursday.

The ISS Progress 77 cargo craft, docked to the Pirs docking compartment, fired its thrusters shortly after 1 p.m. EDT today slightly lifting the station’s orbit. The half-mile orbital boost readies the orbiting lab for the ISS Progress 78 resupply ship due to launch on June 30 from Kazakhstan and dock to the Poisk module two days later.

Immune system research has been underway all week with NASA Flight Engineers Mark Vande Hei and Megan McArthur collaborating on the Celestial Immunity experiment. Vande Hei once again started his day retrieving donor cells from a science freezer, thawing them and spinning the samples in a centrifuge. McArthur followed that work treating the samples to document differences from sample cultures harvested on Earth. Results could lead to improved vaccines and treatments for diseases on Earth, as well as advance the commercialization of space.

Commander Akihiko Hoshide set up the Confocal Microscope today to get ready for the Cell Gravisensing study that seeks to understand how individual animal cells detect gravity. The three-time station visitor also collected and stowed his saliva samples for the Standard Measures study then checked his blood pressure for the Vascular Aging investigation.

NASA Flight Engineer Shane Kimbrough continued his orbital plumbing duties today with more troubleshooting in the Tranquility module’s Water Processing Assembly (WPA). Astronaut Thomas Pesquet of the European Space Agency assisted Kimbrough with the WPA work and also serviced computers and cables throughout the day.

The year’s sixth spacewalk is set for June 2 for external maintenance and science experiment installations on the station’s Russian segment. Cosmonauts Oleg Novitskiy and Pyotr Dubrov, who spent Thursday morning inspecting their Orlan spacesuits, will spend about six-and-a-hours outside the lab during their first career excursions. The duo split up in the afternoon and worked on a variety of life support and ventilation systems.

Life Science Work Fills Day Ahead of June Spacewalks

The Expedition 65 crew is staying focused on numerous life science experiments aboard the International Space Station today while gearing up for three spacewalks in June.

The Celestial Immunity study has been ongoing aboard the orbital lab since shortly after it arrived on the SpaceX Crew-2 mission. NASA Flight Engineer Megan McArthur started Wednesday retrieving donor cell samples from a science freezer before thawing and spinning the cells in a centrifuge. Next, NASA Flight Engineer Mark Vande Hei inoculated and treated the sample cultures to help scientists observe the differences from samples harvested on Earth. Results could lead to improved vaccines and treatments for diseases on Earth, as well as advance the commercialization of space.

Akihiko Hoshide, Japan’s second station commander, spent the day on a variety of human research studies. In the morning, he took glucose measurements and collected blood samples for the Phospho-Aging and Vascular Aging studies looking at bone, muscle and artery changes in space. Hoshide then took turns with ESA Flight Engineer Thomas Pesquet wearing a virtual reality headset and clicking a trackball for the Time Perception experiment. Researchers are exploring how astronauts perceive space and time which may impact navigation and fine motor coordination in microgravity.

Over in the Tranquility module, NASA Flight Engineer Shane Kimbrough, with assistance from Vande Hei and Pesquet, continued more maintenance work on the Water Processing Assembly (WPA) due to a suspected leak. The WPA, which recycles water into drinkable water, has been powered down for several days during the troubleshooting work. The crew is fine and has several months of water supply on the station if necessary.

Next month’s first spacewalk is planned for June 2. Cosmonauts Oleg Novitskiy and Pyotr Dubrov will spend about six-and-a-hours on external maintenance and installing science experiments. Novitskiy worked on Orlan spacesuit maintenance today before joining Dubrov for more Russian cardiac research to understand how weightlessness affects the circulatory system.

In mid-June, two U.S. spacewalks are planned for the installation of a pair of new solar arrays on the station’s Port-6 truss structure. Four more solar arrays will be installed on upcoming spacewalks to augment the orbiting lab’s power systems.

U.S. and Russian Spacewalk Preps, Human Research Aboard Station Today

Spacewalk preparations and biomedical research filled the Expedition 65 schedule on Tuesday. The International Space Station also continues to host a variety of maintenance on science and plumbing systems.

ESA Flight Engineer Thomas Pesquet checked out U.S. spacesuit components ahead of a pair of spacewalks to install new solar arrays on the Port-6 truss structure planned for June. Those solar arrays, the first two of six targeted for installation, will be launched to the station aboard the next SpaceX Dragon mission on June 3.

Commander Akihiko Hoshide worked throughout the day collecting his biological samples and stowing them in science freezers for a pair of human research studies. The Phospho-Aging study looks at rapid bone and muscle loss while the Vascular Aging experiment observes aging-like changes in arteries that take place in microgravity.

Another human research study, the Standard Measures investigation that NASA Flight Engineer Megan McArthur contributed to today, observes and documents the changes to the human body during a long-term spaceflight. McArthur also installed and configured hardware inside the Combustion Integrated Rack to support safe research into fuels and flames on the space station.

In the Tranquility module, NASA Flight Engineer Shane Kimbrough spent the day on orbital plumbing duties. He was assisted throughout Tuesday by Pesquet and NASA Flight Engineer Mark Vande Hei as they serviced the Water Processing Assembly (WPA) to repair a possible leak.

Cosmonauts Oleg Novitskiy and Pyotr Dubrov reviewed procedures for an upcoming spacewalk planned for June 2 for external maintenance and science experiment installations. The duo also partnered up for cardiac research before moving on to communications and systems maintenance in the orbiting lab’s Russian segment.

Maintenance for the WPA in the Tranquility module of the station occurred today as crew members removed the affected parts and configured ducting to perform a dryout of the lines. Maintenance will continue tomorrow with the installation of the replacement units and additional preventative maintenance to restore the hardware to its full functionality.

The WPA was powered off last week due to a suspected leak. This hardware is used to recycle water from multiple sources into clean, drinkable water for crew members aboard the International Space Station.

The crew is in no danger and has multiple spare parts on board to complete the repair process. There is enough water stored on the space station to provide the crew with the necessary consumables for several months if required.

The space station serves a vital role in testing and maturing life support technologies that will be required for future missions to the Moon and Mars. Repairs provide invaluable data to engineers refining these systems for use in future spacecraft and missions.

Monday Kicks Off with Japanese, U.S. Science and Spacewalk Preps

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.
