    Microgravity Science is a frontier interdisciplinary field emerging with the development of China manned space program, a hotspot in space sciences. The Key Laboratory of Microgravity of Chinese Academy of Sciences, founded as the National Laboratory of Microgravity in 1995 and renamed officially in 2008, has become the centers of microgravity science and of user supporting system in China. The first director of the Lab was Prof. Hu Wenrui and the first chair of Academic Committee was Prof. Ling Langying (both are the Academicians of Chinese Academy of Sciences). The current Lab director is Prof. Long Mian and the current Academic Committee chair is Prof. Hu Wenrui.

    The Lab has been focusing on understanding the fundamental priciples and rationales of microgravity fluid physics and promoting the interdisciplinary studies with space material sciences, space life sciences and space biotechnologies. By means of ground-based, drop tower, recoverable satellite, and space payload experiments, the Lab has been conducting the diversified theoretical and experimental investigations on various interdisciplinary fields related to microgravity sciences and, meanwhile, making the great contributions to such the hi-tech developments as fire safety and fluid management highly-required for China manned space program. 

    Current research fields are as follows:
    1.Microgravity fluid physics
    Thermocapillary convection and interfacial phenomena;
    Multiphase flows and related heat transfer
    Complex fluids

    2.Microgravity combustion science
    Combustion mechanism
    Fire safety in manned spacecraft

    3.Space material science
    Solidification process
    Crystal growth

    4.Biomechanics and nano-biotechnology
    Molecular and cellular biomechanics
    Space biotechnology and space life sciences


    Great progresses have been achieved in the following fields:

    1. Microgravity fluid physics
    Liquid bridge (pool) thermocapillary convection and its stability
    Thermocapillary migration of liquid droplets and bubbles
    Two-layer fluids with evaporation and convection

     Studies of thermocapillary migration and interaction of air bubbles

    2. Complex fluids and colloid self-assembly
     Microscopic diagnosis of the stability of dispersion systems
