The Stratospheric Ballooning Association hosts conferences that promote our mission in supporting those that are engaged in high altitude ballooning and other stratospheric activities.  Our annual conference is the Academic High Altitude Conference (AHAC) that is held each year at Iowa State University.  This page will contain historical information on past conferences.


The Academic High Altitude Conference began in 2010 and was held at Taylor University. It was then moved around to several universities. In 2019, a decision was made to establish AHAC at Iowa State University and ISU is now the home for the conference, conference papers, and journal. Below is a listing of all previous conference years. Please note that we are still gathering information from previous conferences and not all conferences have a dedicated page yet.
