The HASB (High Altitude Science and Ballooning) competition is an exciting and educational event designed for enthusiasts and students interested in the fields of atmospheric science, engineering, and technology. Participants are challenged to design, build, and launch high-altitude balloons equipped with scientific instruments to collect data from the upper atmosphere. The competition encourages innovation, teamwork, and practical application of scientific principles. Teams compete to achieve various objectives, such as reaching specific altitudes, capturing unique data, or demonstrating innovative design features. The HASB competition provides a platform for learning, exploration, and advancing our understanding of the Earth's atmosphere.
