NASA | The MMS Mission's Unique Orbit

The video discusses NASA's MMS mission, designed to study magnetic reconnection, a space phenomenon where magnetic energy is explosively converted into plasma energy, causing space weather events like the Aurora. The MMS mission involves four spacecraft in a tetrahedron formation to capture these events. The spacecraft orbits are designed to cross the magnetopause, where solar wind meets Earth's magnetic field, allowing scientists to observe magnetic reconnection in action.
