1. Advanced Composition Explorer (ACE) observes particles of solar, interplanetary, interstellar, and galactic origins, spanning the energy range from solar wind ions to galactic cosmic ray nuclei.
2. The advancements monitoring instruments that 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.
3. The technology that came from the ace mission are various instruments that measure solar winds
4. The Result of the mission changed our understanding of solar wind in the great expanse of space
The Year that this mission occurred was 1997 so it was fairly recently after the hubble was launched into space. The technology of the time was that they were just starting to have things like dvds and tevo. Some major world events happening at the same time were that Steve Jobs was just named Ceo of Apple and that Princess Diana had Just died.
