2024年6月11日 · NASA and other space agencies have studied the health of hundreds of astronauts over the past 6 decades, finding a wide range of impacts, including elevated long-term cancer risks from exposure to space radiation, muscle atrophy and bone loss from life in microgravity, and changes in vision.

Space systems can be crewed (e.g., the International Space Station, SpaceX Dragon) or uncrewed (e.g., telecommunication and navigation satellites). They also vary in size from large structures like the International Space Station (420 tons mass) to small and micro satellites that can weigh less than ten kilograms and are about the size of a ...
