Innovation of Microgravity Geology : New Perspective of Solar System Science through Granular Physics

该研究计划旨在通过国内外科学家的合作，在太阳系科学和颗粒物理学之间建立一个新的跨学科领域，称为“微重力地质学”。为实现这一目标，我们主要集中在小行星和彗星核（如Hayabusa使命）等微重力天体的地质和地貌数据分析，1G环境下的撞击和波传播实验，微重力环境下使用自由落体的撞击和颗粒流实验，落塔真空室，数值模拟以及这些天体上地质过程的建模。这些结果将应用于下一代太阳系小天体探测计划的研究和开发。

This research program aimed to create a new interdisciplinary field between solar system science and granular physics called "Microgravity Geology", under the collaboration among domestic and international scientists. To achieve this goal, we mainly focused on data analyses of geology and geomorphology of microgravity bodies such as asteroids and comet nuclei like Hayabusa mission, impact and wave propagation experiments in 1G environment, impact and granular flow experiments in microgravity environment by using free fall, drop tower vacuum chambers, numerical simulations, and modeling of geological process on such bodies. These results are applied to research and development of next generation plans of solar system small body exploration.
