LDB - Long Duration Ballon Project

Weather ballons are sent up everyday, all over the continent. Three times a year, however, the LDB project sends up a massive weather balloon to circle the continent.

Here's a link to an NSF factsheet on the LDB project in Antarctica: http://www.nsf.gov/news/news_summ.jsp?cntn_id=103063

If your ears aren't perked, just think, "Its like, science in space, man, but without astronauts!"
