This study aimed to evaluate the effect of gravity on the hydrogen bond network of water molecules. A near-infrared spectrometer was installed on a 3D clinostat that reaches 0.1G in approximately 15 min, and the hydrogen bond network of water molecules in water and two types of microporous inorganic minerals was measured. The results showed that the hydrogen bonding network of water molecules changes under low gravity, and the change vary depending on the sample. The effects of low gravity were suggested to depend on the surrounding environment in which the water molecules exist.
