Japanese research satellite to use magnetic read only memory (MRAM) to hunt sprites in the upper-atmosphere

摘要

Sprites, the somewhat whimsical name given to complex upper-atmosphere optical flashes known as transient luminous events (TLE), were first photographed by Space Shuttle astronauts on Oct. 21, 1989, although apocryphal sightings by military and commercial pilots had been reported earlier. Scientific understanding of these short-lived electrical phenomena, however, is practically nil.
