Video: MMS preview briefing

During a Feb. 25 briefing at NASA headquarters, details were discussed about the upcoming Magnetospheric Multiscale (MMS) mission, scheduled for launch March 12 from Cape Canaveral, Florida. MMS will study a phenomenon called magnetic reconnection – a fundamental process during which magnetic fields around Earth connect and disconnect, releasing explosive energy. Magnetic reconnection also occurs throughout the universe and can accelerate particles up to nearly the speed of light.
