Space Station Research: Fiber Manufacturing & Lunar Brewing on ISS

Space Station Research on Fiber Manufacturing

NASA astronaut Jonny Kim worked inside the Destiny module’s Microgravity Science Glovebox, installing specialized hardware for optical fiber production. Ground operators will remotely control the system to pull glass strands and analyze their quality. Producing fibers in microgravity may reduce imperfections compared to Earth-based production, leading to stronger materials for communications and data transfer in both space and on Earth.

Space Station Research on Lunar Brewing

JAXA astronaut Kimiya Yui reconfigured the Cell Biology Experiment Facility-L (CBEF-L) to support the DASSAI MOON study. This unique experiment simulates lunar gravity to ferment sake yeast. Once complete, frozen samples will be returned to Earth for testing. If successful, this research may allow the production of familiar foods and drinks on the Moon, helping future lunar explorers feel more connected to life on Earth.

Protecting Astronaut Cognitive Health in Space

NASA astronaut Zena Cardman continued her work on the CIPHER investigations, a series of human research studies. She processed biological samples and completed computer-based tests designed to track brain function in microgravity. Understanding cognitive changes during spaceflight is critical for developing tools to monitor mental performance and ensure astronauts can safely complete complex tasks on long-duration missions.

Maintaining Space Station Systems for Research

NASA astronaut Mike Fincke focused on life support and communication systems. He inspected thermal hoses, serviced equipment, and replaced a faulty GPS receiver in the Destiny lab. His maintenance work ensures that ongoing space station research remains safe and uninterrupted.

Russian Space Station Research on Health and Balance

Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky studied how weightlessness affects blood vessels and cardiovascular health, while also preparing the Progress 91 cargo craft for its upcoming departure. Meanwhile, cosmonaut Oleg Platonov conducted balance and orientation studies using VR glasses and electrodes, providing new insights into how the human body adapts to space.
