SIERRA FIREBALL DECODED: An explosion over California that rattled homes across at least two states on Sunday, April 22, has been analyzed by NASA’s Meteoroid Environment Office: It was a natural meteoroid the size of a mini-van. Analysts say the space rock exploded in the atmosphere with an energy equal to nearly 4 kilotons of TNT and might have sprayed the Sierra Nevada mountains with meteorites.
