Ahead of the planned February 2025 return, Williams is busy conducting essential maintenance on a US spacesuit for a planned spacewalk. Following the suit checks, she collaborated with Nasa Flight Engineer Butch Wilmore to perform eye examinations using the Ultrasound 2 device. The astronauts took turns scanning each other's eyes while ground-based doctors monitored the health of their corneas, lenses, and optic nerves in real-time. advertisement Wilmore also transferred cargo between the Kibo and Columbus laboratory modules and installed air quality sensors inside Quest, contributing to ongoing research aboard the orbiting laboratory. The crew's activities are vital for maintaining both equipment and living conditions in space. Meanwhile, Flight Engineer Nick Hague explored the potential of micro-algae as a sustainable resource for future space missions. He processed sample containers for installation in the BioLab research facility, aiming to investigate how microgravity and radiation affect these organisms. This research could provide insights into using micro-algae for carbon dioxide removal, oxygen production, and food growth on long-duration missions to the Moon, Mars, and beyond. At the end of the day, Hague, who also commands the upcoming SpaceX Crew-9 mission, joined Williams, Wilmore, and cosmonaut Aleksandr Gorbunov for a departure training session inside the Dragon crew spacecraft.
