Cassini was the surname of a famous family of astronomers, whose members include:
Cassini was an astronomer at the Panzano Observatory, from 1648 to 1669.
Cassini was the first to make successful measurements of longitude by the method suggested by Galileo, using eclipses of the satellites of Jupiter as a clock.
Cassini was employed by Pope Clement IX in regard to fortifications, river management, and flooding of the Po.
Cassini's instrumentation consists of: a synthetic aperture RADAR mapper, a CCD imaging system, a visible/infrared mapping spectrometer, a composite infrared spectrometer, a cosmic dust analyzer, a radio and plasma wave experiment, a plasma spectrometer, an ultraviolet imaging spectrograph, a magnetospheric imaging instrument, a magnetometer, an ion/neutral mass spectrometer.
Cassini's launch trajectory did not bring it within suitable vicinity of any large metropolis and the design of the RTGs would mean that they would be very unlikely to even fracture in the case of a catastrophic mission abort.
Cassini released the Huygens probe on 25 December 2004, by means of a spring.
