PARTS SHEET 6 The Science Instruments
Cassini’s scientific instruments are the reason for having a spacecraft at all. Remote sensing
instruments, such as cameras and spectrometers capture light reflected from Saturn or other targets.
Direct sensing instruments, such as the dust detector and magnetometers measure phenomena
which they encounter in the spacecraft’s immediate environment. Measurements taken by the
instruments are sent back to Earth by the spacecraft either right away, or after being stored aboard for
a convenient time for transmission. Note: the stellar reference units, mounted with the remote sensing
instruments, are not scientific instruments, but part of the spacecraft’s attitude control system.
