The Cassini Timeline. 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.

Mission Summary
The Delivery Schedule.
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.
Master Schedule (updated 12/22/16). This is an “as-planned” listing of observations spanning the interval from May 14, 2004 to November 22, 2016. The list contains 58,320 entries and may be downloaded and sliced and diced to make your own listing. In addition, the linked page allows you to determine DSN data drops to verify that the data should exist in the archive.

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.
