Human-rated spacecraft

Human-rated spacecraft are specially designed vehicles intended to transport astronauts safely into space and back. They undergo rigorous testing to ensure they can withstand the harsh conditions of space travel, including extreme temperatures and radiation, while providing life support systems like oxygen and temperature control. Features also include robust safety measures to protect crew members during launch, orbit, and re-entry. Examples include NASA's Orion and SpaceX's Crew Dragon. The term "human-rated" signifies that these spacecraft meet strict safety standards suitable for carrying people, not just cargo.
