NASA | MMS Mission Overview

Senior Project Scientist Tom Moore outlines the three instrument suites onboard the four MMS spacecraft.

On March 12, 2015, NASA plans to launch the Magnetospheric Multiscale, or MMS, mission. MMS consists of four identical spacecraft that will orbit around Earth through the dynamic magnetic system surrounding our planet to study a little-understood phenomenon called magnetic reconnection.

Watch NASA's new movie to learn more about MMS and the phenomenon of magnetic reconnection, which occurs near Earth, on the sun, in other stars and in the vicinity of black holes and neutron stars.

The Magnetiospheric Multiscale, or MMS, mission will provide unprecedented detail on a phenomenon called magnetic reconnection, which happens throughout the universe and can accelerate particles up to nearly the speed of light.
