Vein scans and pharmaceutical analysis topped the science schedule aboard the Worldwide Area Station on Wednesday. The Expedition 74 crew rounded out the day with Dragon cargo transfers, lab familiarization actions, and life assist upkeep duties.
NASA Flight Engineers Jack Hathaway and Jessica Meir kicked off their shift with vein scans utilizing the brand new Ultrasound 3 gadget delivered final 12 months aboard the Cygnus XL spacecraft. Hathaway led the scans imaging Meir’s neck, shoulder, and leg veins whereas chest electrodes measured her coronary heart cardiac exercise as docs on Earth assisted in actual time. Hathaway then operated the Ultrasound 2 gadget and scanned the veins of ESA (European Area Company) astronaut Sophie Adenot as docs on the bottom monitored. Residing in area long run induces fluid shifts in an astronaut’s physique growing the danger of blood clots—additionally known as thromboembolism—that flight surgeons consistently monitor and search to counteract.
The trio, together with Roscosmos cosmonaut Andrey Fedyaev, continued getting conversant in station techniques and operations whereas getting used to dwelling and dealing in weightlessness. Initially of his shift, Fedyaev wore acoustic sensors round his neck that recorded his fast exhalation serving to docs perceive how microgravity impacts the respiratory system. Adenot serviced pattern processing {hardware} supporting analysis into the event and manufacturing of prescribed drugs in area. Meir wrapped up her day unpacking crew provides and station {hardware} delivered aboard Dragon on Saturday.
NASA Flight Engineer Chris Williams, who has been aboard the orbital outpost since November, labored all through Wednesday with a wide range of life assist duties, medical coaching, and an emergency drill. Williams first measured airflow all through the modules within the station’s U.S. phase then inspected vents for cleanliness and correct configuration. Subsequent, he skilled to make use of medical {hardware}, together with an automatic exterior defibrillator, and carried out totally different procedures similar to conducting eye exams and administering drugs. Williams additionally joined his crewmates Sergey Kud-Sverchkov and Sergei Mikaev from Roscosmos and practiced utilizing emergency respirators within the unlikely occasion of a chemical leak aboard the station.
Kud-Sverchkov and Mikaev, who arrived with Williams aboard the Soyuz MS-28 spacecraft, spent Wednesday focusing totally on analysis and upkeep within the station’s Roscosmos phase. Kud-Sverchkov wrapped up an in a single day automated images session that imaged the Earth’s nighttime environment in near-ultraviolet wavelengths. Mikaev configured scientific {hardware} that controls and processes knowledge for quite a few experiments. The duo additionally cut up their day with laptop {hardware} replacements within the Nauka science module and air flow system upkeep within the Zvezda service module.
