In March 2015, NASA launched the Magnetospheric Multiscale (MMS) mission, comprising four spacecraft designed to study magnetic reconnection—a process where magnetic fields explosively realign, releasing vast amounts of energy. This phenomenon is pivotal in driving space weather events, such as solar flares and coronal mass ejections, which can disrupt Earth’s satellites, power grids, and communication systems. The MMS mission aims to provide detailed insights into magnetic reconnection by flying in a tetrahedral formation through Earth’s magnetosphere, collecting high-resolution measurements to enhance our understanding of space weather and its potential impacts on modern technology.
