I did my postdoc working on the BARREL (Balloon Array for Relativistic Radiation Belt Electron Loss). I gave a seminar once that made it on YouTube that you can see to learn more about some of that work https://youtu.be/tTJ4rjMBwQM.

BARREL looked at how particles in #Space - in our #Magnetosphere get lost in our #Atsmosphere. It was a ton of fun and I hope to launch many more balloons in the future (But rockets and satellites are also really cool too!)
