NASA | Goddard's Speedy MMS Instruments Will Measure Mysterious Physics

The video discusses magnetic reconnection, a process where magnetic fields merge and release energy, occurring in various environments like the sun and Earth's magnetosphere. Understanding this phenomenon is crucial for space weather prediction and nuclear fusion. The Earth's magnetosphere is a convenient study location due to its impact on space weather. The video highlights the challenges of measuring magnetic reconnection, which occurs rapidly. It details the instruments used, including spectrometers developed at Goddard, and the collaborative effort in building and launching the MMS spacecraft to study this phenomenon.
