Welcome to the Cassini Archive Page

Cassini data are delivered to the PDS 9-12 months after acquisition and are delivered every three months. PDS must validate those data before they are considered certified. This may result in a delay between the time when Cassini delivers data and the time when PDS makes the data available. Alternately, PDS may choose to put data online while they are being validated, stating that they are not certified. PDS urges caution when using any data that have been released by the PDS for less than three months.

Organization of The Cassini Mission. The mission is divided into 4 phases: the Cruise Phase (including the Jupiter Flyby Dec 2000-Jan 2001), the Prime Mission (including the Huygens Probe Landing), the Equinox Mission and the Solstice Mission. Data from all phases are stored sequentially in the PDS. Tables and graphics associated with various aspects will help you scope the mission.

Finding Cassini Data. Although the data from the various instruments are archived within the appropriate discipline nodes, it is assumed that the user would be interested in Saturn, Rings, Titan and other satellites or in fields and particles data; hence, these web pages are set up to facilitate searches of this sort.

Saturn
Rings
Titan
Icy Satellites
Small Satellites
Fields and Particles and Aurora data

Understanding the Instrument and the Archived Data. In an effort to supplement the limited availability of higher-order reduced data products, the Cassini Instrument Teams are generating users' guides to supplement the original documentation. Access to the guides and other useful information can be found at the following pages.

CAPS - Cassini Plasma Spectrometer
CDA - Cosmic Dust Analyzer
CIRS - Composite Infrared Spectrometer
HRD - High Rate Detector
INMS - Ion and Neutral Mass Spectrometer
ISS - Imaging Science Subsystem
MAG - Magnetometer
MIMI - Magnetospheric Imaging Instrument
RADAR - a Radar instrument
RPWS - Radio and Plasma Wave Spectrometer
RSS - Radio Science Subsystem
UVIS - Ultraviolet Imaging Spectrograph
VIMS - Visual and Infrared Mapping Spectrometer

Observation geometry in "SPICE" format may be obtained at the NAIF node
