The Magnetospheric Multiscale (MMS) Mission is a NASA robotic space mission to study the Earth's magnetosphere, using four identical spacecraft flying in a tetrahedral formation. [1] The spacecraft were launched on 13 March 2015 at 02:44 UTC. [2]

2016年11月4日 · The Magnetospheric Multiscale (MMS) mission is a Solar-Terrestrial Probe mission comprising four identically instrumented spacecraft that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence.

2023年1月14日 · MMS (Magnetospheric Multiscale) is a Solar-Terrestrial Probe mission comprising four identically instrumented spacecraft to discover the fundamental physics of magnetic reconnection using Earth's magnetosphere as a laboratory.

2014年8月8日 · The Magnetospheric Multiscale, or MMS, mission will provide the first three-dimensional views of this fundamental process that can accelerate particles to nearly the speed of light. MMS uses Earth’s protective magnetic space environment, the magnetosphere, as a natural laboratory to directly measure reconnection.

On Oct. 15, 2015, the four spacecraft of NASA’s Magnetospheric Multiscale, or MMS, mission entered the tightest flying formation ever achieved (shown here in an artist concept) – a pyramid shape, with each satellite just six miles from each other.

The four MMS spacecraft will be developed, integrated, and tested at GSFC. Each satellite has an octagonal shape that is approximately 3.5 meters wide and 1.2 meters high. The satellites spin at 3 RPM during science operations.

2015年3月13日 · The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes Program mission within NASA's Heliophysics Division. The MMS mission, consisting of four identically instrumented spacecraft, will use Earth's magnetosphere as a laboratory to study magnetic reconnection.

2015年3月13日 · NASA’s MMS mission studies 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.
