1014Last Weekend's ISU Flight
- Oct 5, 2004Here's an update on the ISU launch last weekend. It was the best flight I've seen in
Idaho. No surface winds and a 20 mile flight that landed a few hundred feet from the
road in a plowed farm field. There were well placed roads for the entire flight. we
spent lots of time with the farmer of the property we launched from and at a truck
stop showing visitors the balloon and the UI View map.
I ran out into the field as the balloon landed and missed grabbing it by about 3 feet.
The plowed field was uneven and I couldn't change my running direction fast enough
without tripping. I'll email a few photos when I get them from ISU. I'm attaching a
spreadsheet of the science data my flight collected.
Another topic. BalloonSats are popular with college students. The University of
Idaho recommends using the plastic tube of a ball point pen to run the load line
through. ISU says they saw metal pipe (from lamps) being used at Boulder. We lost
three BalloonSats when the metal tube of one BalloonSats abradied the load line. I
recommend using plastic tubing from hobby shops for the loal line and three cord
suspension system. I'll post photos of the design shortly. I would also recommend
using 1/2" thick styrofoam in place of the foam core. I'll write up an article on this for
Nuts and Volts for early next year. I'm planning on getting Boise School District
students to make a bunch of BalloonSats for launch.
