By studying how physical processes behave in reduced gravity and microgravity, scientists unlock groundbreaking discoveries that wouldn’t be possible on Earth. These studies help improve scientific and commercial applications in fields such as materials, manufacturing, electronics, and chemical engineering. NASA’s Physical Sciences Informatics (PSI) database makes the results of these experiments available to all, allowing researchers to make even more discoveries from these precious data. 

PSI includes data collected from experiments aboard the International Space Station (ISS), Space Shuttle, commercial cargo flights, and free-flying space robots. It also includes data from relevant ground-based studies. Research areas include combustion science, fundamental physics, fluid physics, complex fluids, materials science, and biophysics. 

Each study catalogued in PSI comes with open access to both raw and processed data, as well as supporting resources such as models, images, documentation, and a list of publications that stem from the study. Additional studies continue to be populated in the database as the team works to create a complete record of all flown experiments and add new experiments as the study of microgravity physics carries on.
