The clinostats used in the SMG experiments and their corresponding principle models. a The 2-D clinostats with a horizontal axis used to generate SMG condition on ground. b The 2-D clinostats with a vertical axis used to generate 1G control condition on ground. c The schematic diagram of mechanical principle of the different clinostats. SMG: Axis of rotation is perpendicular to the direction of the gravity vector, which is used to simulate microgravity effects on ground; NG: The samples fixed in the metal support are rotating, used as the dynamic control of SMG; 1G: The samples fixed in the metal support are static and are used as the static control of SMG
