NASA | MMS Science Overview: The Many Mysteries of MMS

The video tutorial explains the concept of magnetic reconnection, a process where magnetic energy is rapidly converted into plasma energy, affecting space weather and impacting Earth. It highlights the importance of measuring reconnection in multiple locations using a tetrahedron of spacecraft to understand its spatial variations. The tutorial also describes the two orbital phases of the Magnetospheric Multiscale (MMS) mission, which studies reconnection on both the day and night sides of Earth's magnetosphere. The video concludes with the potential applications of this research in improving predictive models for space weather and the technological advancements in particle measurement.
