On its journey, MMS will observe a little-understood, but universal phenomenon called magnetic reconnection, responsible for dramatic re-shaping of the magnetic environment near Earth, often sending intense amounts of energy and fast-moving particles off in a new direction. Not only is this a fundamental physical process that occurs throughout the universe, it is also one of the drivers of space weather events at Earth. To truly understanding the process, requires four identical spacecraft to track how such reconnection events move across and through any given space in 3D.", "items": [], "extra_data": {} }, { "id": 344785, "url": "https://svs.gsfc.nasa.gov/11485/#media_group_344785", "widget": "Video player", "title": "", "caption": "", "description": "

Since it launched, MMS has made more than 4,000 trips through the magnetic boundaries around Earth, each time gathering information about the way the magnetic fields and particles move. A surprising result was that at the moment of interconnection between the sun’s magnetic field lines and those of Earth the crescents turned abruptly so that the electrons flowed along the field lines. By watching these electron tracers, MMS made the first observation of the predicted breaking and interconnection of magnetic fields in space.

Magnetic reconnections take place on the day and night side of the planet and are caused by the interaction of Earth’s magnetic field with charged particles released from the sun called the solar wind. The four spacecraft, each identically engineered, make up the Magnetospheric Multiscale, or MMS, mission. Flying in a pyramid-shaped configuration, the spacecraft will orbit Earth and pass through areas known to be reconnection sites. Each reconnection event unleashes a massive burst of energy that can accelerate particles within Earth’s protective magnetic environment, known as the magnetosphere, to nearly the speed of light. Sensors onboard the spacecraft will measure the energy and movement of charged particles during an event, providing scientists with the first three-dimensional look at this phenomenon.
