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, we had 35 knot winds at Halley 6 so haven't been able to do too much. The weather forecast is still predicting that the winds will taper off tomorrow, so we are still planning to launch another balloon tomorrow afternoon. SANAE IV is also having bad weather still, but are hopeful for a Wednesday launch. We are also getting close to terminating Payload 1J. It is still above 29 km altitude and very close to McMurdo right now. We are waiting for it to move back over land before we cut it down.
Hopefully I'll have more exciting news to report tomorrow! Robyn
