On-orbit reuse of space payloads can reduce project costs and shorten ground preparation time, while ensuring that functions and performance meet requirements and Under the premise of safety and reliability, carrying out on-orbit missions in the form of reflight is an important way to deal with the problems of high density of space missions and high development costs. The use of refly payloads has the following three characteristics.

a) Need to recover scientific experiment equipment and samples after completing the mission in orbit;

b) Space science programs have continuity and commonality, so there are cases where the functions and structures of payload equipment are similar or even the same However, the generalized and standardized payload development method increases the possibility of re-flying missions on different spacecraft platforms. sex;

c) The quality level of components used in payload equipment has been continuously improved, ensuring that the design life of the payload far exceeds that of space science The mission cycle, the payload can still work normally after recovery, and has the basic ability to perform re-flying missions. This document will standardize my country's space payload re-flying missions, promote the establishment of a generalized and internationalized space science platform, and facilitate the global Large-scale, long-term, and multi-type space science experiment projects within the scope of cooperation. Space Payload Refly Requirements

1 Scope

China's national requirements for re-flying space payloads. A payload that has flown and been returned - from a recoverable satellite, a space station, or a reusable vehicle - is a valuable asset and a suspect one. It has been through launch, orbit and re-entry; it has been vibrated, thermally cycled, irradiated and possibly exposed to atomic oxygen; and it may have been operated well beyond its qualification life. Whether it can fly again is not a question of appearance. The requirements have to establish what must be inspected, what must be re-tested, what has a defined life that has been consumed - batteries, propellant seals, mechanisms with a cycle count - and what evidence must exist from the first flight for the second to be authorised. As China's programme moves toward reusable vehicles and a permanently occupied station, the question shifts from exceptional to routine, which is why it now has a standard.

This document specifies the work items and content requirements for the space payload to perform the ground phase before the reflight mission. This document is applicable to the execution of payload plans on space vehicle platforms such as satellites, spaceships, space laboratories, space stations, and space probes Ground preparation for the refly mission.
