NASA’s Record-Shattering, Theory-Breaking MMS Mission Turns 10
5 min readNASA’s Record-Shattering, Theory-Breaking MMS Mission Turns 10 Since its launch on March 12, 2015, NASA’s MMS, or Magnetospheric Multiscale, mission has been rewriting our understanding of a key physical process that is important across the universe, from black holes to the Sun to Earth’s protective magnetic field. This process, called magnetic reconnection, occurs when magnetic field lines tangle and explosively realign, flinging away nearby particles. Around Earth, a single magnetic reconnection event can release as much energy in a couple of hours as the entire United States uses in a day. Over the past 10 years, thousands of research papers with discoveries by MMS have enabled a wide range of technical and scientific advances, such as those about the conditions on the Sun that create space weather, which can impact technology and communications at Earth. It has also enabled insights for fusion energy technologies. “The MMS mission has been a very important...
