Brain research at ISS ahead of cargo mission launch
NASA Flight Engineer Nichole Ayers took her turn on Wednesday in the Columbus laboratory module wearing neck and chest electrodes measuring oscillations in the blood flow from her brain to the heart for the Drain Brain 2.0 human research experiment. Similarly, Ax-4 private astronaut Tibor Kapu wore a cap that imaged blood flow in his cerebral artery using doppler ultrasound for the Cerebral Hemodynamics investigation.
Veteran astronaut and Ax-4 Commander Peggy Whitson assisted Kapu with the biomedical hardware and measured his blood pressure inside the Tranquility module. Both studies are supported by different organizations with the first seeking to prevent space-caused blood clots and the second to protect crew visual processing and perception in microgravity, the statement said.
Ayers later joined her station crewmates Commander Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) and NASA Flight Engineer Anne McClain for eye checks using high-resolution, near-infrared medical imaging hardware.
McClain led the B Complex optical investigation in the Harmony Module as Ayers and Onishi peered into the ocular device while doctors on the ground examined their optic nerve at the back of the eye in real time. Researchers are exploring using B vitamin supplements as a method to protect crew vision in microgravity, as per NASA.
NASA Flight Engineer Jonny Kim began his shift inspecting portable emergency hardware including fire extinguishers and breathing masks. After his lunch period, he joined his Soyuz MS-27 crewmates Sergey Ryzhikov and Sergey Zubritskiy, both flight engineers from Roscosmos, and practiced using respirator masks in the unlikely event of a chemical leak onboard the orbital outpost.
Ryzhikov and Zubritskiy started their shift repairing a Roscosmos treadmill in the Zvezda service module. Ryzhikov also wore virtual reality glasses for a study observing how a crew member's balance and visual perception adjust to microgravity. Zubritskiy serviced research physics hardware that measures neutron radiation. Flight Engineer Kirill Peskov spent his shift in the orbital outpost's Roscosmos segment servicing orbital plumbing gear and activating Earth observation equipment.
Ax-4 crewmates Shubhanshu Shukla and Slawosz Uznanski-Wisniewski partnered together in Columbus and studied using near-infrared technology to record brain activity for constructing brain-computer interfaces. Uznanski-Wisniewski wore a specialized cap connected via Bluetooth to a laptop computer recording his brain activity while Shukla optimized the signal quality and calibrated the hardware.
The pair also recorded and downlinked video of crew activities for the Astronaut Mental Health study. Shukla also looked at muscle cell stem cultures through a microscope to understand the muscle repair process in weightlessness.
The next uncrewed cargo mission, Progress 92, is counting down to its launch at 3:32pm (local time) on Thursday from the Baikonur Cosmodrome in Kazakhstan. Progress 92 is scheduled to dock to the Poisk module at 5:27pm (local time) on Saturday delivering about three thousand pounds of food, fuel and supplies for the orbiting lab residents, the statement said.

11 crew members aboard Axiom mission resume space science work
Washington DC: The 11 crew members aboard the International Space Station, representing Expedition 73 and Axiom Mission 4 (Ax-4), resumed their space science duties on Tuesday. Their research focused on various areas, including brain circulation, the observation of cancer cells, and the study of biotechnology, among other investigations, as per a statement by NASA. Station Commander Takuya Onishi, from the Japan Aerospace Exploration Agency (JAXA), attached sensors to his neck and chest to measure how blood flows from the brain to the heart. Doctors will review the data to understand how blood circulation adapts to weightlessness. Meanwhile, Ax-4 crewmates Peggy Whitson and Tibor Kapu also studied cerebral circulation for another experiment designed for their mission. Whitson assisted Kapu, who wore a cap, using a Doppler ultrasound to image blood flow in his cerebral artery while a cuff measured his blood pressure. Doctors will use the results to help protect the crew's visual processing and perception in microgravity. Whitson later peered inside a fluorescence microscope at cancer cells to learn how to detect and prevent cancer earlier, the statement read. NASA Flight Engineers Anne McClain and Nichole Ayers spent a portion of their shift assisting the Ax-4 crew on Tuesday. McClain helped the private astronauts operate the research hardware throughout the orbital lab and guided their science activities. Ayers set up a microscope in the Destiny laboratory module that Ax-4 crew member Shubhanshu Shukla used to view how tardigrades, tiny aquatic animals, survive numerous harsh climates, including microgravity. Ax-4 astronaut Slawosz Uznanski-Wisniewski explored the use of nanomaterials in wearable devices that monitor crew health. NASA Flight Engineer Jonny Kim began his shift alongside Onishi by collecting blood samples, processing them in a centrifuge, and stowing the specimens in a science freezer for preservation. Kim later reorganised the hardware inside the Harmony module's maintenance work area and then installed ventilation system components inside the Quest airlock, as per the statement. The uncrewed, trash-packed Progress 90 cargo craft ended its stay at the orbital outpost today, undocking from the Poisk module at 2:42 pm (local time). It will reenter Earth's atmosphere for a fiery, but safe demise above the South Pacific Ocean, completing a seven-month space delivery mission, NASA stated. Waiting to replace the spacecraft is the Progress 92 cargo craft standing at the launch pad at the Baikonur Cosmodrome in Kazakhstan. The Progress 92 is counting down to its launch at 3:32 pm (local time) on Thursday. It will arrive at the orbital lab on Saturday and dock with Poisk at 5:27 pm (local time), delivering approximately three thousand pounds of food, fuel, and supplies for the orbiting lab residents. Roscosmos Flight Engineers Sergey Ryzhikov and Alexey Zubritskiy began their day training on the telerobotically operated rendezvous unit, or TORU, for Saturday's approach and rendezvous of the Progress 92. Ryzhikov then set up hardware to capture hyperspectral imagery of landmarks in Mexico and South America. Zubritskiy photographed the Progress 90 as it departed the station.
