Sprites, those beguiling electrical flashes of light above thunderstorms, raise so many questions: Why do they take the shapes they do? What conditions in the upper atmosphere trigger them? How do sprites affect Earth’s global electric circuit, and what is their contribution to the energy in Earth’s upper atmosphere? On October 26, 2022, NASA’s Spritacular project began asking volunteers to help answer these questions. Happy Birthday, Spritacular!
