Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA) will serve as the commander of the expedition, the third JAXA astronaut to take command of the station.[1] It will continue the extensive scientific research conducted aboard the ISS, focusing on various fields, including biology, human physiology, physics, and materials science. The crew members will also maintain and upgrade the space station systems.
