A strong need has emerged in the aerospace industry for a well-founded and effective failure prevention technique or process that can be employed during the conceptual design of high-risk aerospace systems. In this paper, we describe a methodology to support risk assessment and failure prevention during the earliest stages of spacecraft design and mission planning. The three-step procedure, an extension of the Function-Failure Design method, utilizes detailed information from existing subsystems and systematically abstracts this information to a level that can be used during conceptual design. During this process, we address the issue concerning the level at which systems containing a combination of electrical and mechanical components should be functionally modeled. The complete method is described in general before being applied to two major unmanned spacecraft subsystems.

In recent decades, human exploration of space has gradually deepened, and more and more countries and regions have successfully sent astronauts into space. How to complete the space experiment as efficiently and safely as possible in the shortest time with limited resources has become an important issue in the field of aerospace technology. Taking full account of such matter, we consider that ergonomics in design stage is one of the most effective ways to solve this problem. The microgravity environment is the biggest difference between ground and space. Therefore, the study of ergonomics under the microgravity environment is of great significance. This article deeply analyses and summarizes the physiological differences between human and normal gravity under microgravity environment. From the ergonomics point of view, the requirements for spacecraft design and space mission planning are put forward for the reference of engineers and scholars.
