On 28 March, the European Space Agency (ESA) took a major step forward in strengthening Europe's ambition for more resilient satellite navigation, as the first two satellites of the Celeste in-orbit demonstration mission lifted off from New Zealand aboard Rocket Lab’s Electron. Their mission is to begin testing a complementary low Earth orbit layer for Galileo.
The liver plays a vital role in human health, regulating metabolism and blood nutrient levels, filtering toxins, and synthesizing important proteins for blood clotting. It is also sensitive to changes in diet, behavior, and environmental factors, meaning it will also respond to changes in gravity. Despite considerable research into liver metabolism and function aboard the International Space Station (ISS), unanswered questions remain about how liver cells sense gravity and convert mechanical stress into metabolic responses.
