Life science, robotics and space construction kept the Expedition 66 crew busy aboard the International Space Station on Wednesday. The orbital residents also worked on spacesuits and inspected a Russian module.
Eye checks continued on the orbiting lab with NASA astronaut Thomas Marshburn taking charge as crew medical officer during the afternoon. The three-time station astronaut used medical imaging gear, or optical coherence tomography, to scan the eyes and retinas of NASA Flight Engineers Kayla Barron and Raja Chari.
Marshburn began his day studying how to produce and maintain nutrients during long-term space missions. Chari later worked on communications components inside a pair of U.S. spacesuits. Barron started her morning cleaning the Cell Biology Experiment Facility, an incubator with an artificial gravity generator.
NASA Flight Engineer Mark Vande Hei set up the free-flying Astrobee robotic assistants and tested an autonomous rendezvous algorithm for the ROAM technology demonstration. ESA (European Space Agency) astronaut Matthias Maurer resumed the Concrete Hardening experiment studying potential lunar and planetary construction techniques.
Roscosmos Flight Engineer Pyotr Dubrov photographed the condition of window panes in the Zvezda service module for inspection by engineers on the ground. Station Commander Anton Shkaplerov transferred water from tanks in the ISS Progress 79 resupply ship into the space station.
