Human-rated or man-rated are terms used to describe the certification of a spacecraft or launch vehicle as worthy of transporting humans.
In spaceflight, a human-rating certification is the assurance that the space system accommodates human needs, effectively utilizes human capabilities, controls hazards with sufficient certainty to be considered safe for human operations, and provides, to the maximum extent practical, the capability to safely recover the crew from hazardous situations. In the United States, the National Aeronautics and Space Administration (NASA) has published NASA Procedural Requirement NPR 8705.2B - Human Rating Requirements for Space Systems, defining the certification process and a set of technical requirements to be applied to its crewed space systems in addition to the standards and requirements that are mandatory for all of NASA's space flight programs.
