Prediction Software To be able to accurately predict where a high altitude balloon will land is next to impossible unless you are able to consider all of the variables that come into play. Fortunately, flight prediction software based online at (www.nearspaceventures.com) is able to consider all of these variables and put them to use. This software takes into account the weather predictions for the area in question and plots take off, landing, and balloon burst points on a map. In days leading up to the launch, flight prediction software was used to predict the course of the flight using weather forecast details from the closest weather station and details about ascent and descent rate which we obtained from the balloon manufacturer. This tool was first used to predict the flight path from Boscobel, WI. The software predicted that the payload would land near Dubuque, Iowa, which was unacceptable. Mt. Horeb, WI was finally decided on as the most convenient site that would result in a landing location around Monroe, WI. For the second launch the same prediction software from (www.nearspaceventures.com) was used to again try and find an optimal landing zone as discussed above. Below is a figure showing the results of the prediction for the second launch. Figure 3: Flight Prediction for Launch 2 Launch Day Launch On Saturday July 18 th , the launch team and 4 members of the payload team headed to Mt. Horeb to execute the first launch of the 2009-2010 season. The first task for making our first launch successful was finding a safe place to launch the balloon. By using the satellite view on Google maps we were able to find a nearby football field. The launch site worked well due to the fact that it had no trees or power lines in the immediate area and the site was elevated relative to the surroundings. After finding the site we brought out all of our gear and laid out everything we would need on the grass. A tarp was laid on the ground so the balloon could be filled without causing any damage to it. Rubber gloves were worn by the launch team members when handling the balloon to avoid getting skin oil on the balloon which can hamper the balloons expansion at high altitudes. The balloon was then filled 4
which had been a problem in the past due to a check valve in the connection fitting to the helium tank. After unsuccessfully looking for a new tank fitting without a check valve, the decision was made to simply drill out the check valve to provide better air flow. This decision proved to be a success as the fill time of the balloon went from about 2 hours to 15 minutes. While the fitting now doesn’t have a check valve it is still safe since the flow of helium can be regulated by the tanks valve. At approximately 11:00AM the balloon and the payloads underwent a final check along with turning the GPS system on and checking to see how it was performing. A few minutes later the balloon was released and instantly we knew something wasn’t right. The balloon slowly began ascending and then started descending. The members present rushed to grab the balloon and it was brought back to the launch pad. An oversight had been made while reading the scale which measured the amount of lift the balloon was providing. Since the wind was blowing the balloon sideways while the lift was being measured, the wind added on to the amount of lift significantly. After holding the balloon steady we were able to get the lift up to around 6lbs, about 3/2 the weight of our payload. The balloon was released a second time, this time with much better results. The members present watch the balloon rise away and then proceeded to pick up all of the gear and begin tracking the balloon. Figure 5: GPS Generated Track of Balloon Flight Figure 4: Balloon and Payload Tracking Possibly the most fun part of being a member of the balloon launch team is tracking the balloons. Following the balloon on our laptops, our convoy of three vehicles drove around back roads trying to stay close to the balloon. We had set up two laptops in separate cars, both tracking the balloon. This reduced the risk of losing the balloon due to computer problems. We tracked the balloon from Mt. Horeb, WI to just north of Monroe, WI. The StratoSat tracking system preformed well and got us to the landing point. 5
