BARREL (Balloon Array for Radiation belt Relativistic Electron Losses) is a multiple-balloon investigation that will study Earth's Radiation Belts.
Atmospheric losses of relativistic electrons play an important role in radiation belt dynamics; precipitation into the atmosphere may even completely deplete the radiation belts in some cases.
BARREL is the first NASA Living With a Star Geospace Mission of Opportunity, and will support NASA's RBSP (Radiation Belt Storm Probes) mission.
The third campaign is really heating up! We hope to have an exciting set of new collaborations just by virtu of launching in a new location, ESRANGE in Kiruna Sweden. (Congrats Sweden on the Eurovision win!)
However, we've also just had a set of papers all come out over the last six months that should be highlighted.
