Magnetospheric Multiscale Observatories

Magnetospheric Multiscale (MMS) observatories are ready for launch and processed in a clean room at the Astrotech Space Operations facility in Titusville, Florida.

MMS is an unprecedented NASA mission to study the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. MMS consists of four identical spacecraft that work together to provide the first three-dimensional view of this fundamental process, which occurs throughout the universe.



The mission observes reconnection directly in Earth’s protective magnetic space environment, the magnetosphere. By studying reconnection in this local, natural laboratory, MMS helps us understand reconnection elsewhere as well, such as in the atmosphere of the sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system’s heliosphere and interstellar space.
