Ivy says,
"This Advanced Composition Explorer [ACE] model was designed with the intermediate to advanced builder in mind.What ACE does in layman's terms:
The Earth sits in a stream of accelerated particles coming in from the Sun, interstellar material, and galactic sources. The study of these energetic particles will broaden our understanding of the formation and evolution of the solar system, as well as the astrophysical processes involved. The Advanced Composition Explorer (ACE) spacecraft, carrying six high-resolution sensors and three monitoring instruments, will sample low-energy particles of solar origin and high-energy galactic particles, with a collecting power 10 to 1000 times greater than past or planned experiments."
