NASA Mission To Study Magnetic Fields Launches Tonight

The United Launch Alliance Atlas V rocket with NASA’s Magnetospheric Multiscale spacecraft onboard rolls out of the Cape Canaveral Air Force Station Space Launch Complex 41 Vertical Integration Facility on route to the launch pad, March 11, 2015. It will carry the four identical MMS spacecraft into orbit to provide the first three-dimensional view of magnetic reconnection. (Aubrey Gemignani/NASA)

Tonight NASA will launch its 20-story rocket Atlas V into space to study Earth’s magnetic field. What is the magnetic field and how does it affect us here on Earth? It’s responsible for the beautiful aurora displays, but Here & Now’s Jeremy Hobson speaks with Craig Pollack of NASA to find out more.
