Since opportunities to conduct experiments in space are scarce, various microgravity simulators and analogs have been widely used in space biology ground studies. Even though microgravity simulators do not produce all of the biological effects observed in the true microgravity environment, they provide alternative test platforms that are effective, affordable, and readily available to facilitate microgravity research. The Microgravity Simulation Support Facility (MSSF) at the National Aeronautics and Space Administration (NASA) John F. Kennedy Space Center (KSC) has been established for conducting short duration experiments, typically less than 1 month, utilizing a variety of microgravity simulation devices for research at different gravity levels. The simulators include, but are not limited to, 2D Clinostats, 3D Clinostats, Random Positioning Machines, and Rotating Wall Vessels. In this chapter, we will discuss current MSSF capabilities, development concepts, and the physical characteristics of these microgravity simulators.
由于在太空中进行实验的机会稀缺，各种微重力模拟器和模拟物已被广泛应用于空间生物学地面研究。尽管微重力模拟器无法产生在真实微重力环境中观察到的所有生物学效应，但它们提供了替代的测试平台，这些平台具有有效性、经济性和可及性，有助于开展微重力研究。美国国家航空航天局（NASA）约翰·F·肯尼迪航天中心（KSC）的微重力模拟支持设施（MSSF）已经建立，用于进行短期实验，通常不到 1 个月，利用各种微重力模拟设备在不同重力水平下进行研究。这些模拟器包括但不限于二维回旋器、三维回旋器、随机定位机和旋转壁容器。在本章中，我们将讨论当前 MSSF 的能力、发展概念以及这些微重力模拟器的物理特性。
