The airframe is made from 10mm thick Cellfoam 88. Since it has a hard flat surface, I was able to glue Styrene plastic to it without it melting very badly. I filled in gaps with Gorrila glue.
The Balloon CubeSat measures two temperatures, internal and external. The flight computer is based on a BalloonSat Mini and will make measurements once per minute during the mission. It is my hope that a project like this will make a great introduction to satellites.
