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.
Good morning all. I apologize for not sending out a report for the last couple of days. Our internet has slowed to a crawl. Something is wrong with the satellite link, but they are working on fixing it. I think it seems a little faster this morning, but maybe I'm just getting used to it!
As mentioned before, we are having bad terrestrial weather at both SANAE IV and Halley. Winds were up to 40 knots at SANAE IV yesterday with whiteout conditions. Our winds at Halley are just shy of 30 knots right now. The forecast shows the winds dying down on Monday afternoon, so we are still hoping for a launch opportunity from Halley then.
We currently have 6 payloads in the air (1D, 1I, 1J, 1K, 1N, 1O). Payload 1M was terminated this morning at 1030 UT with last position 70.4S, 93.98W. Payload 1J has been in the air for 11 days! It is likely to be terminated in the next day. Alexa has been posting some nice plots on the blog. I can't upload much from here right now, but you can see maps of the payload locations and some plots of our first x-ray events at relativisticballoons.blogspot.com. Nothing too exciting just yet, but it has given us something to look at and is a great opportunity to see how our coordination with the Van Allen Probes teams is working. Many thanks to all the Van Allen Probes team, especially John Wygant, for all the time and effort they've put into coordinating with the BARREL team!!
