Nasa has posted an online story about the University of Kentucky's Big Blue project. Look for it at:

HF Radio

We try and start an HF net approximately 45 minutes prior to launch on 7.235 MHz. If that frequency is busy we try 7.228 or 7.240 MHz.

The net control for this flight will be Bruce, NA�BR.
