About Edge of Space Sciences (EOSS)

Edge of Space Sciences (EOSS) is a Denver, Colorado based non-profit organization that promotes science and education by exploring frontiers in amateur radio and high altitude balloons. Click "Read More" for more information.

Our organization works with educators, offering valuable opportunities to enhance their students' studies of science, technology, engineering and math (STEM) through real, hands-on experience. We provide FAA coordination, launch, tracking and recovery of the payloads. Each year, our volunteers spend thousands of hours to enable student STEM programs to reach the Edge of Space.
