Microgravity University is a program that lets astronauts in space learn about science and research. Microgravity means very little or no gravity, and astronauts in space experience this type of environment. Astronauts in space can do experiments that wouldn't be possible on Earth because of the lack of gravity. Astronauts learn more about space exploration and science by doing experiments in this type of environment. Microgravity University teaches astronauts how to use technology and tools to help them research and experiment in space.
