Month: September 2022

Four of the seven Expedition 67 crew members took the day off on Monday following a busy week of science and maintenance aboard the International Space Station.

Last week saw Flight Engineers Kjell Lindgren, Bob Hines, Jessica Watkins, and Samantha Cristoforetti focus on upgrading life support systems. The quartet moved the Life Support Rack from the Harmony module to the Tranquility module to demonstrate its capacity to remove carbon dioxide and recover oxygen for the crew. The Oxygen Generation System rack was moved from Tranquility to the U.S. Destiny laboratory module to test its ability to detect hydrogen and protect its systems.

Hines and Watkins would spend Thursday and Friday exploring how cognition and perception is affected when living in space long-term. Scientists are using the data to help astronauts adapt to the differing gravity environments of the Moon, Mars, and beyond. Lindgren wrapped up last week testing the station’s new U.S. toilet system while Cristoforetti tended to vegetables growing using non-soil methods such as hydroponics and aeroponics.

The orbiting lab’s three cosmonauts are preparing for their return to Earth at the end of September completing a six-month mission. Commander Oleg Artemyev was joined by Flight Engineers Denis Matveev and Sergey Korsakov for an early morning conference with support personnel who would retrieve the crew after parachuting to Earth inside the Soyuz MS-21 crew ship. Artemyev and Matveev then tested the Lower Body Negative Pressure (LBNP) suit to adapt for the return to Earth’s gravity. The LBNP suit counteracts microgravity’s tendency to pull fluids toward a crew member’s upper body.

During midday, Korsakov joined his cosmonaut crewmates for the LBNP activities to help prepare their bodies for the gravity adjustment when they return to Earth. Korsakov spent the rest of Monday on computer maintenance in the Nauka multipurpose laboratory module as well orbital plumbing duties in the station’s Russian segment.

More human research, including how astronauts move around in microgravity as well as the effect of weightlessness on vision, packed the science program aboard the International Space Station on Thursday. The seven-member Expedition 67 crew also continued its ongoing focus on life support, orbital plumbing, and electronics systems maintenance.

The lack of an up and down reference while living in microgravity affects how astronauts manipulate and grip objects. Researchers want to get a closer understanding of that behavior to keep astronauts safe in the differing gravitational environments of deep space travel, planets, moons, and asteroids. NASA Flight Engineers Bob Hines and Jessica Watkins took turns seated inside the Columbus laboratory module on Thursday for the long-running GRIP experiment. The duo gripped and maneuvered a specialized device in response to pre-programmed stimuli so scientists can gain insights into a crew member’s cognition and perception during spaceflight.

Hines would go on to orbital plumbing duties filling water containers in the Unity module. Watkins wrapped up her day installing radio frequency identification (RFID) readers inside Unity. The installation work is part of the RFID Smart Sensing study that seeks to improve inventory accuracy and item location on the station.

ESA (European Space Agency) Flight Engineer Samantha Cristoforetti checked radiation detection hardware and collected microbe samples from the area around the Veggie space botany facility for analysis. NASA Flight Engineer Kjell Lindgren stowed biology research hardware and then tested the station’s new toilet system located in the Tranquility module.

Eye checks were back on the schedule on Thursday for Commander Oleg Artemyev and Flight Engineer Sergey Korsakov. The duo took turns scanning each other’s retinas using medical imaging hardware with real-time support from doctors on the ground. The eye exams help researchers understand how weightlessness affects vision and the shape of the eye. Flight Engineer Denis Matveev spent his day servicing Russian life support gear and stowing hardware for disposal inside the ISS Progress 80 resupply ship docked to the Poisk module.

Space botany and eye checks were at the top of the research schedule aboard the International Space Station on Wednesday. Life support system upgrades also continued during the middle of the week for the Expedition 67 crew members.

Understanding how plants and humans are affected by long-term exposure to microgravity is key to prolonging mission success beyond low Earth orbit and to the Moon, Mars, and beyond. NASA and its international partners are learning how crews can sustain themselves independently of ground support for longer periods of time.

Growing vegetables on space missions is critical so astronauts can feed themselves without the support of cargo missions regularly launching from Earth to replenish crews. The XROOTS space agriculture study does not use soil and is exploring growing radishes and mizuna greens on the station using hydroponic and aeroponic methods. Today, NASA Flight Engineer Kjell Lindgren recirculated fluids for the botany experiment and checked the condition of the growing plants. The study takes place inside the Columbus laboratory module and may inform ways to grow crops on larger scales during missions farther away from Earth.

Lindgren later assisted his fellow astronauts Bob Hines and Jessica Watkins of NASA, including Samantha Cristoforetti of ESA (European Space Agency), as they wrapped up two days of life support system upgrades. The quartet moved the oxygen generation system (OGS) rack from the Tranquility module to the U.S. Destiny laboratory module, then moved the Life Support Rack (LSR) from the Harmony module to Tranquility. The foursome finished rack power and data cable connections as well as fluid umbilical installations. The LSR is demonstrating capturing carbon dioxide from the cabin air and recovering 50% of its oxygen for crew use. New sensors are also being tested to detect hydrogen and protect the OGS rack.

The orbiting lab’s three cosmonauts from Roscosmos began and ended their day with eye checks. Commander Oleg Artemyev and Flight Engineers Denis Matveev and Sergey Korsakov took turns in the morning scanning each other’s eyes using the Ultrasound 2 device, part of the station’s Human Research Facility-1. In the afternoon, Korsakov took charge as Crew Medical Officer and used medical imaging gear to picture Matveev’s retinas. The eye exams help doctors understand how weightlessness affects vision and the shape of the eye. The trio then spent the rest of the day stowing spacewalk tools, working on life support and electrical systems, and analyzing the Zvezda service module’s atmosphere.

Life support and computer maintenance filled the Expedition 67 crew schedule on Tuesday following a busy Labor Day aboard the International Space Station.

The station’s four astronauts focused on a variety of biology and physics research on the U.S. holiday as they photographed growing vegetables and explored how fuel behaves in space. In the orbiting lab’s Russian segment, the crew’s three cosmonauts continued cleaning up after last week’s spacewalk and studied how to exercise effectively in weightlessness.

On Tuesday, the crew’s attention turned to servicing orbital hardware ensuring the space station’s life support systems and computer networks operate continuously.

NASA Flight Engineer Kjell Lindgren removed the Tranquility module’s oxygen generation system (OGS) rack and installed it in the U.S. Destiny laboratory module. He was assisted by fellow Flight Engineers Bob Hines and Jessica Watkins who helped remove gear and clear the path for the transfer of the refrigerator-sized OGS rack. The trio completed the installation and cable connections during the afternoon.

Watkins also had time to join ESA (European Space Agency) Flight Engineer Samantha Cristoforetti as she transferred the Life Support Rack from the Harmony module to Tranquility. Hines and Lindgren wrapped up the day reconfiguring the modules and reinstalling the station’s bathroom, the Waste and Hygiene Compartment located in Tranquility, following the rack transfers.

Roscosmos Commander Oleg Artemyev and Flight Engineer Denis Matveev spent the afternoon installing a computer desktop in the Zvezda service module. The new work area is wide enough to hold three laptop computers supporting a variety of operations including monitoring Russian spaceships arriving and departing. Flight Engineer Sergey Korsakov worked on a pair of human research experiments on Tuesday, the first exploring ways to maintain space fitness and the second researching how international crews and mission controllers can communicate successfully.
