U.S. students in grades 6–12 are invited to team up with their classmates to develop a science or technology experiment idea for NASA’s TechRise Student Challenge. The challenge calls for an experiment designed for one of two flight vehicles: a high-altitude balloon or a rocket-powered lunar lander. Sixty winning teams will be selected to build their proposed idea, receiving cash funding, flight time, and logistical and technical support from NASA engineers to turn their idea into reality. Entries are due Oct. 20. Sign up now!
