High Altitude Balloons are large weather balloons that carry cameras and sensors to the edge of space, allowing breath-taking imagery and cutting edge science. They can be built for a few hundred dollars in just a few weeks by people of all ages with no prior experience. The process of launching and recovering a high altitude balloon is incredibly fun, while providing critical lessons in hands on engineering and teamwork.Learn More
The GSBC is the world’s largest high altitude ballooning event, where teams in various locations around the world launch simultaneously - last year 60 teams from 18 countries on 6 continents flew together. Participants ranged from students and teachers, to amateurs and professionals, to children and their parents. Many had never touched high altitude balloons before the event. We provide a central website with examples, tutorials, and expert support that allow you to fly your ideas high into the atmosphere - join the fun and show the world what you can do!Learn More
The purpose of this website is to provide you with the resources you need to fly an ambitious high altitude balloon and help others do the same. The forums allow you to share your ideas, get feedback, and see what others are thinking. The prizes provide some ambitious goals for what to do with your balloon, while the tutorials pages can help you make this happen. The Hosted Payloads and Balloon Buddies programs will let you help teams in need. And don’t forget to check out the launch map and see just how many other people are involved.
