Flight Data

We have collected data from the barometer and made these graphs.



We noticed something odd with the temperature. Notice the spike near the apex of the balloon's flight. We aren't sure exactly why this happened, but it's very interesting!

UPDATE:
After a quick refresher from our fifth grade earth science class, we were reminded that our balloon would have passed through the ozone layer from about 25,000 to 30,000 m. The ozone layer absorbs sunlight which accounts for the warmer temperatures. It is fascinating that the temperature changed as much as 60 degrees F in just a few minutes. Its one thing to learn this in the classroom but to hold the equipment in my hands that had just passed through the ozone layer and the stratosphere collecting our own data adds a whole new element of understanding. This understanding is what we hoped to convey to the elementary students that we involved in our project.

Screen Shots From Flight



Here are a few screenshots from the video footage.

A quick look at the data reveals that the flight took about 111 minutes and reached an altitude of around 38,000 meters (124,000 feet or 24 miles).  It was subject to a low temperature of around -38 degrees Celsius.

We will post some better pictures and video as we process it.
