Mission Overview - Objective

Our team’s mission is to send a balloon satellite to an altitude of 100,000 feet and have the satellite:

1) Take pictures and a digital recording of the flight

2) Measure the radiation levels in the upper atmosphere

Mission Overview - Goals

Our aim with these experiments is to:

1) Obtain a visual record of near space and balloon burst

2) Discover how the radiation levels vary at higher altitudes.
