The Kibo Experiment Data Archive established by JAXA preserves vast amount of experimental data obtained onboard the Japanese Experiment Module “Kibo” in the International Space Station (ISS). This archive contains valuable data obtained in the microgravity environment. We hope these precious data contribute to the advancement of science and technology.

This archive includes experiments of the following categories.
Marangoni convection is the flow driven by the presence of a surface tension gradient which can be produced by temperature difference at a liquid/gas interface. The convection in liquid bridge of silicone oil is generated by heating one disc higher than the other. Scientists are observing flow patterns of how fluids move to learn more about how heat is transferred in microgravity. The liquid bridge size differs according to the experiment. The liquid flow patterns were observed three dimentionally by using multiple cameras, while temperature distribution was monitored by a thermo-viewer.
Ice Crystal Experiment, Facet Experiment, Ice Crystal 2 Experiment, and Nano Step Experiment are crystal growth experiments. They both aim to reveal the pattern formation of crystal growth under convection free microgravity condition. The crystal growth processes under various conditions were observed in situ by using amplitude modulation microscope and Mach-Zehnder type interferometers.
