A new, interactive version of a timeline of NASA's Cassini mission to Saturn is now available online. The journey starts with launch on Oct. 15, 1997, and presents illustrated milestones and discoveries since then, including the finding of geysers on the moon Enceladus and lakes on the moon Titan. The timeline runs through the expected completion of the mission in 2017.
