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.
Today was another busy day down south! At Halley, we started setting up for a launch at 7am, but the winds were just not cooperating. The SANAE team also had an opportunity and got a launch off at 1316 UT (Payload 1O). After the successful SANAE launch, the Halley team had more stable weather and was able to launch Payload 1I at 1806 UT. Neither team expects to have a launch opportunity until early next week due to weather, so we were very excited to get two more up today! Additionally, we terminated Payload 1B tonight at 2017 UT (60.94S, 120.93S). The altitude was low on this balloon so we were no longer getting any good science data from it. We still have 7 balloons up! And today we saw our first precipitation event. We havent' had a chance to look at the data just yet and it wasn't a huge event, but we are excited to see something interesting! Hopefully we'll be posting some data plots in the near future!
