Advanced Composition Explorer
E648470
The Advanced Composition Explorer (ACE) is a NASA spacecraft launched in 1997 that measures energetic particles from the solar wind, interplanetary medium, and galactic sources to study the composition and dynamics of space plasmas and provide space weather monitoring.
