Far above Earth, life on the International Space Station never slows down. As the world turns below, eleven astronauts are busy floating through their cosmic laboratory, carrying out vital science that could change life both in space and on Earth.

Focus on Brain, Cancer, and Space Biology
The Expedition 73 and Axiom Mission 4 crews resumed their duties on Tuesday. Their research explored how space affects blood flow, cancer cells, and tiny resilient creatures called tardigrades.

Station Commander Takuya Onishi from Japan’s space agency, JAXA, fitted sensors to his neck and chest. This experiment monitors how blood moves between the brain and heart in weightlessness. Doctors will analyse the data to better understand circulation in space.

Ax-4 crew members Peggy Whitson and Tibor Kapu also joined the cerebral circulation study. Kapu wore a special cap while Whitson used a Doppler ultrasound to image his cerebral artery. A blood pressure cuff added further data for the experiment.
