Saturn (The Associated Press / CBS Newspath) -- NASA's two-decade long mission to Saturn is coming to a fiery end.
Thursday, the Cassini spacecraft will make a final dramatic dive into the ringed planet's atmosphere.
Since arriving in Saturn in 2004, the probe has beamed back more than 300 thousand images of the ringed giant and its dozens of moons.
The only spacecraft ever to orbit Saturn, Cassini spent the past five months exploring the uncharted territory between the planet and its dazzling rings.
On Monday, Cassini flew past jumbo moon Titan one last time. NASA calls it the goodbye kiss, which put the spacecraft on its final, no-way-out path.
