Biology and Physics Research Advance as ISS Crews Transition Duties
Last Updated on March 23, 2026 by Tsiyon Hone
Life science and physical research continued to take center stage aboard the International Space Station as astronauts balanced scientific investigations with crew handover activities. The work aims to improve human health in space while supporting future missions and the growing space industry.
NASA astronaut Zena Cardman focused on human health research, collecting and processing blood samples as part of the CIPHER study, which tracks how spaceflight affects the body before, during, and after missions. She also completed cognitive tests designed to measure how astronauts adapt to navigating in microgravity. Later, Cardman exercised using specialized equipment while wearing biometric sensors that monitor cardiovascular and aerobic health.
NASA flight engineer Jonny Kim supported both research and crew transitions. In addition to assisting with biomedical experiments, he prepared Astrobee robotic free-flying assistants for remote and autonomous operations. These free-flying robots may eventually reduce astronauts’ workload by handling routine tasks. Kim also helped train newly arrived cosmonauts on station exercise equipment as he prepares for his return to Earth aboard the Soyuz spacecraft.
Meanwhile, veteran crew members guided new arrivals through daily life in orbit. Russian cosmonauts Sergey Ryzhikov and Alexey Zubritsky focused on packing equipment and preparing the spacecraft for departure, while newly arrived crew members received hands-on training in station systems and procedures.
Science investigations extended beyond biology. NASA astronaut Mike Fincke conducted photography experiments inside the Microgravity Science Glovebox to study how cryogenic fluids behave in microgravity: research that could improve spacecraft fuel tank design. In Japan’s Kibo laboratory, astronaut Kimiya Yui worked on carbon dioxide removal technology, contributing to life-support systems planned for future Artemis missions to the Moon.
As crews transition responsibilities, the International Space Station continues to support cutting-edge research that benefits life on Earth and prepares humanity for deeper exploration of space.
