Space science experiment ground verification requirements

1 Scope

China's national standard for the ground verification of space science experiments. It specifies the verification objectives, the requirements, the types of verification and their conduct. Every space experiment is rehearsed on the ground, and this standard sets out what those rehearsals must establish. There are several distinct kinds and confusing them is a common failure. Functional verification shows the apparatus works at all. Environmental verification shows it survives launch and orbit. Scientific verification shows the experiment answers the question, usually by running the same protocol on the ground and confirming that the result is what theory predicts under gravity - because if the ground control does not behave as expected, the flight result cannot be interpreted. And operational verification shows that the procedure can be executed by a crew member or by command, which is where experiments most often fail after everything else has passed.

This standard specifies the ground verification objectives, verification requirements, verification types, and verification for conducting space science experimental projects on space vehicles. Process, validation experiments, and experimental validation summary and evaluation requirements. This standard applies to the use of satellites, spacecraft, space laboratories, space stations and other space vehicles for space life science and biotechnology. Ground verification of scientific research projects in the fields of technology, space material science, space fluid physics and combustion science, and space basic physics. You can refer to scientific experimental projects using sounding rockets, high-altitude balloons and other aircraft and space experimental tasks with similar processes. use.

4 Verification purpose

The ground verification purpose of space science experiments is as follows:

a) verify the correctness, feasibility and rationality of the space science experiment program;

b) verify the satisfaction of scientific experimental devices with scientific experimental needs and engineering requirements;

c) Verify that the functions, performance, and environmental adaptability of the experimental samples and experimental devices meet the requirements of the space mission.
