This is the citizen science arm of the Global Fireball Observatory (GFO), a network of all-sky cameras detecting fireballs entering Earth's atmosphere, determining their 3-D paths, estimating their masses, helping to locate resulting meteorites that reach the ground, and determining their orbits prior to encountering the Earth. This helps us better understand the near-Earth environment around us in space and gives us valuable cluse about the origin and history of the Solar System. Fireballs in the Sky expands the scope and range of the projrct's observations beyond the fixed camera stations by recruiting citizen scientist observers around the world to make visual observations of fireballs and record and submit their observations via a free augmented reality app for mobile devices (Android and iOS).
