Physical Sciences Informatics System

NASAs Physical Sciences Research Program conducts fundamental and applied physical sciences research, with the objective of enabling exploration and pioneering scientific discovery. NASAs experiments in the various disciplines of physical science reveal how physical systems respond to the near absence of gravity. They also reveal how other phenomena that have a small influence on physical systems in Earth’s gravity can dominate system behavior in space.

Not only are we using the ISS to perform investigations, we are also taking the results from these investigations and making them available to researchers via open data. The PSI system ( allows researchers to access the data from physical sciences investigations, most of which have been performed on the ISS.
