The seven-member Expedition 73 crew wrapped up a weekend of housecleaning and relaxation then kicked off Monday with muscle and brain research aboard the International Space Station. Their Axiom Mission 4 (Ax-4) counterparts worked throughout the weekend and began the week taking a closer look at muscle cells and exploring brain computer interfaces. The public and private biology studies complement each other while the research data and hardware are supported by different organizations.

11 residents are living and working aboard the International Space Station today following the docking of Axiom Mission 4 (Ax-4) at 6:31 a.m. EDT on Thursday. The seven Expedition 73 crew members welcomed the four Ax-4 astronauts and are now helping them get up to speed with orbital lab systems and prepare for two weeks of microgravity research.
