Dear friends, It looks like we will need at least 8 ounces (250 grams) of dirt in each sample. Â We need enough to insure adequate signal above the background....
Saturday's launch is a go at this time. I think we'll have enough BalloonSats for two 3,000 gram balloons. Look for callsigns KD4STH-11, 8, and 7 plus K0KU-11...

Payload has been recovered. Slight damage to one of the video cameras. Does anyone know if Garmin will provide firmware update to allow the TH-D72a to work...
The th-d72a does allow you to use an external GPS. Not perfect but at least a solution.  On the other hand, isn't the 72a kind of an expensive radio to...
