Because we are Amateur Radio Operators and we love science. The ability to track a balloon at 100,000 feet, take photos of the upper atmosphere has furthered interest in our hobby and our club. This project has inspired many smaller, similarly related projects by members of our club. We’ve had more participation and interest in this project, than most other projects we’ve run. Clubs around Michigan and Ohio have heard about this launch and are waiting for the launch.

We're interested in reception reports of our balloon. Send us a note a let us know if you heard our beacon or transmitters. 

Delivery System

Kaymont 1200g Balloon 
Diameter at launch: 4.88 meters (16 feet)
Ascent Rate: 5 meters  (16.4 feet) / second
Color: White
Material: Latex
Supplier: Kaymont Balloons, NY - http://kaymontballoons.com/ 

RocketMan 6.5 foot Diameter 
50lb breaking strength Nylon cord.
The cordage is used to tether the balloon to the parachute, and from the parachute to the balloon. Three feet from payload to parachute and 5 feet from parachute to balloon.

Because of the changes in winds, final launch location will be decided 12 hours prior to launch. Winds will be re-checked the morning of the launch, and a “Go Ahead” will be determined then. 
A final analysis of ground based wind-speed will be the final “Go/No Go” deciding factor upon arrival at the launch site. 

Our prediction tool (http://predict.habhub.org)only goes 180 hours out from the present time, so you may have to adjust the dates in the predictions below.
