BARREL Balloon Launch

Caption

A BARREL balloon launches over Halley Research Station during the Antarctic summer of 2013-2014. The BARREL mission was created to observe precipitating electrons from Earth's radiation belts, supplementing observations by NASA's Van Allen Probes. During a January 2014 solar storm, BARREL measured solar electrons in addition to radiation belt electrons, allowing the team to map how parts of Earth's magnetic field shift and change during a solar storm.
