The Advanced Composition Explorer was launched August 25, 1997 carrying six high-resolution spectrometers that measure the
elemental, isotopic, and ionic charge-state composition of nuclei from H to Ni (1≤Z≤28) from solar wind energies (∼1 keV nucl−1)
to galactic cosmic-ray energies (∼500 MeV nucl−1). Data from these instruments is being used to measure and compare the elemental
and isotopic composition of the solar corona, the nearby interstellar medium, and the Galaxy, and to study particle acceleration
processes that occur in a wide range of environments. ACE also carries three instruments that provide the heliospheric context
for ion composition studies by monitoring the state of the interplanetary medium. From its orbit about the Sun-Earth libration
point ∼1.5 million km sunward of Earth, ACE also provides real-time solar wind measurements to NOAA for use in forecasting
space weather. This paper provides an introduction to the ACE mission, including overviews of the scientific goals and objectives,
the instrument payload, and the spacecraft and ground systems.
