SATURN DAILY
NASA Announces Cassini End-of-Mission Activities

On Sept. 15, NASA's Cassini spacecraft will complete its remarkable story of exploration with an intentional plunge into Saturn's atmosphere, ending its mission after nearly 20 years in space. News briefings, photo opportunities and other media events will be held at NASA's Jet Propulsion Laboratory in Pasadena, California, and will air live on NASA Television and the agency's website.

NASA also will hold a media teleconference Tuesday, Aug. 29 to preview activities for Cassini during its final two weeks.

Launched in 1997, Cassini arrived in orbit around Saturn in 2004 on a mission to study the giant planet, its rings, moons and magnetosphere. In April of this year, Cassini began the final phase of its mission, called its Grand Finale - a daring series of 22 weekly dives between the planet and its rings.

On Sept. 15, Cassini will plunge into Saturn, sending new and unique science about the planet's upper atmosphere to the very end. After losing contact with Earth, the spacecraft will burn up like a meteor. This is the first time a spacecraft has explored this unique region of Saturn - a dramatic conclusion to a mission that has revealed so much about the ringed planet.

Cassini flight controllers will monitor the spacecraft's final transmissions from JPL Mission Control.
