Human-rating certification

Human-rating certification, also known as man-rating or crew-rating, is the certification of a spacecraft or launch vehicle as capable of safely transporting humans. There is no one particular standard for human-rating a spacecraft or launch vehicle, and the various entities that launch or plan to launch such spacecraft specify requirements for their particular systems to be human-rated.

NASA
One entity that applies human rating is the US government civilian space agency, NASA. NASA's human-rating requires not just that a system be designed to be tolerant of failure and to protect the crew even if an unrecoverable failure occurs, but also that astronauts aboard a human-rated spacecraft have some control over it. This set of technical requirements and the associated certification process for crewed space systems are in addition to the standards and requirements for all of NASA's space flight programs. Maximum sustained acceleration is limited to 3 g. ULA has since been awarded $6.7 million under NASA's Commercial Crew Development (CCDev) program for development of an Emergency Detection System, one of the final pieces that would be needed to make these launchers suitable for human spaceflight. SpaceX is using Dragon 2, launched on a Falcon 9 Block 5 rocket, to deliver crew to the ISS. Dragon 2 made its first uncrewed test flight in March 2019 and has been conducting crewed flights since Demo-2 in May 2020. Boeing's Starliner spacecraft is also a part of the Commercial Crew Program since Boeing CFT in June 2024. ==CMSA==
CMSA
The China Manned Space Agency (CMSA) operates and oversees crewed spaceflight activities launched from China, including the Shenzhou spacecraft and Tiangong space station. ==Roscosmos==
Roscosmos
Roscosmos, a Russian state corporation, conducts and oversees human spaceflights launched from Russia. This includes Soyuz spacecraft and the Russian Orbital Segment of the International Space Station. == ISRO ==
ISRO
The space agency of India, ISRO, oversees planned human spaceflights launched from India. On 13 February 2024 the CE-20 engine, after a series of ground qualification tests, was certified for crewed Gaganyaan spaceflight missions. The CE-20 will power the upper stage of the human-rated version of the LVM3 (formerly known as GSLV Mk III) launch vehicle. ==Private spaceflight companies==

Each private spaceflight system builder typically sets up their own specific criteria to be met before carrying humans on a space transport system. == See also ==
