Next Flight

Colorado Space Grant Consortium Summer Flight

Update 7/23/19:  Launch site is shifted to LIMON due to Deer trail violations and I-25 violations at other sites.  Payload plans updated to reflect new launch site.

Update 7/23/19:  Added tracker info, grids, breakfast (time pending)

One 3000 gm balloon, If cloud cover prevents launching heavy, we will fly 2 balloons.  Note that the lite balloon beacons are reversed (ie 292H->293L) 

*NEW* Live tracking of the balloon is available here.  Instructions on how to use the tracker can be found here.  

Flight prediction is shown here.
