Requirements for space science experiments

1 Scope

China's national standard for the requirements analysis of space science experiment projects. It specifies the basis, the principles, the process, the content and the preparation of the science requirements document. The document it governs is the one that translates a scientific question into something engineers can build. A scientist wants to know how a particular alloy solidifies without convection; the spacecraft team needs to know the temperature range, the gradient, the duration, the sample size, the data rate, the power, the mass and the crew involvement. Every ambiguity left in that translation becomes a dispute later, usually when it is too late to change anything. Requiring the analysis to be done to a standard, and written down in a defined form, is what prevents the common failure of space science: an instrument built to a specification that satisfies the engineering review and cannot answer the question that motivated it.

This standard specifies the basis, principles, processes, content, and SRD preparation of space science experiment projects for conducting science experiment needs analysis. Claim. This standard applies to space life science and biotechnology experiments, space material science experiments, microgravity fluid physics and combustion science. And other basic fields of microgravity physics experiments. Space science experiments in other areas can be implemented by reference.
