Fast Auroral Snapshot Explorer

FAST was NASA's second Small Explorer mission, designed to resolve the rapid plasma processes that accelerate particles above Earth's auroral regions. Its particle analyzers, electric-field sensors, and magnetic-field instruments captured high-rate measurements while the spacecraft crossed the zones where the northern and southern lights are energized.

Launch Site
Outcome
FAST reached its highly inclined elliptical orbit and returned more than twelve years of detailed particle and field observations of auroral acceleration and magnetosphere-ionosphere coupling. The spacecraft's science-data acquisition ended after orbit 51315 on April 30, 2009.
