April 18 - 21, 2014


Everywhere! Teams are welcome to launch from anywhere in the world.

What is the Global Space Balloon Challenge (GSBC)?

The Global Space Balloon Challenge is an international education outreach project to encourage people from around the world to build and launch their own high altitude balloons. Over a single weekend, teams from all over the world will launch balloons to the edge of space, recover them, and share the photos and data that they have collected. Our goal is to encourage people of all ages to get their hands dirty building their own space hardware, and to promote the spirit of hardware hacking and international STEM collaboration.

The launches will be between April 18 - 21, 2014, and will take place in countries across the world! So far we already have teams signed up from the US, UK, Spain, Australia, and Japan… and the list keeps growing!

The challenge will include competitions for Best Photograph, Best DesignHighest Altitude, and Best Experiment. Check out the Challenges page for more information!

What is a high altitude balloon (HAB)?

The term high altitude balloon is used to describe a large weather balloon (typically filled with helium) attached to a box that houses sensors and instruments. HABs usually burst between 60,000 to 120,000 feet (18 to 37km). While this altitude technically isn't "space", it is referred to as "near space" and still high enough to let you take incredible pictures, collect useful data, run experiments, or even test hardware that is preparing for actual launch into space.


Why should you get involved?

Building a high altitude balloon is a fantastic project for both new and and experienced hardware builders. A simple balloon might consist of a few sensors, while an advanced balloon might consist of altitude control, pointing control, a data collection system… the possibilities are endless! By getting involved with the GSBC you will get to work on a project that is only as complex as you are comfortable working with, and will give you the perfect opportunity to learn new skills. Through the project, you’ll be able to communicate and collaborate with teams all around the world, as well get building advice from some of our many industry partners or experienced teams.

Head over to the “Get Involved” pages where you can sign up a new team or find an existing team to join. We look forward to seeing what exciting things you build and send to space!
