Space biology work and science hardware maintenance and were the main research goals for the Expedition 66 crew aboard the International Space Station on Wednesday. The orbital residents also checked out life support gear and worked on cargo transfers.
Three NASA astronauts, Mark Vande Hei, Thomas Marshburn and Kayla Barron, joined each other in the Kibo laboratory module during the afternoon and set up external research components. Vande Hei installed the Multi-Purpose Experiment Platform (MPEP) in Kibo’s airlock that will later be placed outside in the vacuum of space. Marshburn and Barron assisted with the MPEP installation work ahead of tiny satellites, or CubeSats, being deployed from the device into Earth orbit.
Marshburn then joined NASA Flight Engineer Raja Chari for vein scans in the Columbus laboratory module. Chari once again led the biomedical activities as crew medical officer using the Ultrasound 2 device to scan Marshburn’s neck, shoulder, and leg veins. Doctors on Earth monitor the health checks in real time to gain insight into how long-term microgravity affects the human body.
Barron also tended to the oxygen generation system before analyzing microbe samples collected from inside BEAM, the Bigelow Expandable Activity Module. Flight Engineer Matthias Maurer of ESA (European Space Agency) installed the ANITA-2 cabin air analyzer then inspected the Muscle Atrophy Research Exercise System ahead of upcoming new component work.
Commander Anton Shkaplerov worked throughout Wednesday in the station’s Russian segment on electronics maintenance on cargo transfers from the ISS Progress 79 resupply ship. Shkaplerov also spent some time on a study researching how international crews and mission controllers relate during a long-duration spaceflight. Flight Engineer Pyotr Dubrov spent most of the day installing payload interface controller units while also finding time for immunity system research work.
