ACE Instrumentation Page

The ACE spacecraft consists of a two-deck irregular octagon, about 1.6 meters (65 inches) across and about 1 meter (40 inches) high. Eight of the scientific instruments which measure a variety of particle types are mounted to the main body of the satellite. Attached to the solar panels is the ninth instrument (see table below...), a pair of magnetometers.
