Bread-loaf-sized satellite Firefly on lightning & gamma rays, most powerful natural particle accelerator in atmos.
(quote)
Firefly is a new mission to study lightning and gamma rays with CubeSats, small satellites in the shape of a cube.
Firefly, it's called, this new small satellite mission sponsored by the National Science Foundation (NSF). It's designed to help solve the mystery of the most powerful natural particle accelerator in Earth's atmosphere: TGFs, or terrestrial gamma-ray flashes. TGFs likely result from thunderstorms.
The mission is the second project under the new NSF CubeSat program. A CubeSat satellite, about the size of a loaf of bread, consists of three cubes attached end to end in a rectangular shape.
