【】Its fiery death comes as no surprise.

No one can ever say that Cassini went quietly into its good night.。

At about 7:55 a.m. ET on Friday, mission controllers on Earth got official word that the Cassini spacecraft -- a joint operation of NASA, the European Space Agency, and the Italian Space Agency -- had burned up in Saturn's atmosphere, vaporizing in about one minute.。

Scientists have been planning to send Cassini into Saturn's atmosphere for some time. Instead of allowing Cassini to spin out of control, possibly impacting one of the planet's moons that could host life, mission controllers sent it on a collision course with the planet it spent more than a decade gazing upon for our benefit.。

The Cassini spacecraft launched in 1997. It has been exploring Saturn and its many moons since it arrived at the ringed planet in 2004.。

Cassini followed along as Saturn went through its alien seasons and made plenty of discoveries along the way. The spacecraft is responsible for transforming our understanding of Saturn's part of the solar system, sending back photos of moons never before seen from close range, and finding evidence of an ocean beneath the moon Enceladus' icy crust.。Mashable Light SpeedWant more out-of-this world tech, space and science stories?Mashable Light SpeedWant more out-of-this world tech, space and science stories?Sign up for Mashable's weekly Light Speed newsletter.  。

In total, Cassini took more than 450,000 photos, orbited Saturn 294 times, and traveled 4.9 billion miles since launch. 。

And up until the end, Cassini was doing what it does best: Gathering and sending back invaluable data to eager researchers back on the planet that bore it.。

The spacecraft beamed back data to scientists on Earth up until the moment it started to break apart like a meteor in Saturn's atmosphere.
。

One of the craft's instruments, the ion and neutral mass spectrometer, tasted the planet's atmosphere during its descent through it, relaying its findings to Earth as one of its last gasps of communication. 。

This kind of data could help scientists figure out how Saturn evolved, even though its mission is now over. We've never been able to sample Saturn's atmosphere directly before, so even in its death, Cassini is breaking new ground.

And perhaps that's the best way to honor Cassini now that it's gone.。

The spacecraft has contributed so much to our knowledge of the solar system, and its data will be used for decades to come. Scientists will continue to pour over the bits and pieces of the information Cassini gathered to come up with new theories, validate ideas, and bolster previous work. 。

Yet aside from one mission to Europa planned in the coming years, NASA has no missions on the books back to Saturn or other planets in the outer solar system. Our close-range eye on that part of our cosmic backyard is now closed.。Featured Video For You 。Featured Video For You 。NASA has discovered a water world in our solar system capable of sustaining life。
