Space safety refers to the measures and practices designed to protect astronauts, spacecraft, and the environment in outer space. This includes avoiding collisions with space debris, which are defunct satellites and other fragments orbiting Earth. Organizations like NASA and ESA monitor these objects to ensure safe travel and operations in space. Another aspect of space safety involves ensuring that spacecraft are built to withstand harsh conditions, such as extreme temperatures and radiation. Proper training for astronauts is also crucial, as they must be prepared for emergencies, including equipment failures or unexpected situations while on missions to the International Space Station or beyond.
