We plan to launch a low cost high altitude weather balloon,using simple materials,that will be mentioned in the lesson plan,along with its properties and use. Our first section will talk about assembling materials and getting it ready for the launch,which will be followed by the process that happens during the flight of a HAB. The conclusion will be with it's tracking using SPOT and recovery along with cautions that has to be taken into consideration before and after launching a HAB. A quick read through this website will hopefully give you a clear idea as to how a HAB works and guide you throughout the launch and recovery.
