Racing to Launch Balloons

Like children flying a kite, scientists race through the Antarctic snow to launch one of 20 balloons as part of NASA's BARREL (Balloon Array for Radiation belt Relativistic Electron Losses) mission. Each balloon is equipped with instruments to help track how electrons from giant radiation belts surrounding Earth travel down magnetic field lines toward the poles. Credit: S. Spain
