Axiom 4 mission’s crewmates began conducting biomedical research aboard the International Space Station on Tuesday. Expedition 73 and Ax-4 crews found electrical muscle stimulation and cellular immunity. The Cargo transfers and exercise gear maintenance take a day for orbital residents.

Takuya Onishi, Situation Commander from JAXA( Japan Aerospace Exploration Agency), has begun the shift in continuation of his space biology studies. His blood and saliva samples are being collected for storage and processing. Further, he spun the specimens in a centrifuge and placed the blood samples in the freezer. After that, he stowed the samples in the incubator.

According to a report from NASA, the samples will be analysed to determine the effect of microgravity on cellular immunity, observe stress-related immune reactions, and learn about how to treat symptoms of immunity. The flight engineers Johnny Kim, Anne McClain, and Nichole Ayers spent their day on orbital lab maintenance and further support activities of the crew. Kim focused mainly on orbital plumbing as he replaced and drained the Tranquillity module.

Ayers checked cables and power components in the Destiny laboratory module and deactivated and placed the microscope. McClain took the cognition test on the laptop and kept on supporting the Ax-4 crew at a time of a busy schedule.

Ax-4 Crew Explores Muscle Stimulation and Space Suit Fabric Efficiency in Microgravity

Veteran astronaut Peggy Whitson and her Ax-4 crewmates Shubhanshu Shukla, Tibor Kapu and Uznański-Wiśniewski conducted numerous space investigations throughout the lab. The private scientists in their second full week on the station found out that the electrical muscle simulation escalates the space-related and muscle atrophy in space. Ax-4’s other experiments looked at suit fabrics promote thermal comfort with exercising the weightlessness, crew health and agriculture in space.

Sergey Ryzhikov and Alexey Zubritskiy worked together on the Zvezda service module, repairing and organising components on a treadmill, one of the two inside the space station, which included the COLBERT treadmill. Kirill Peskov started his day by going through the biological samples from the crewmates. At the end of his shift, he transfers water from Progress 92 cargo craft and unloads the stuffs of hardware and crew supplies.
