Here Are the First Stunning Photos From Cassini's Historic Enceladus Flyby

Yesterday, Saturn’s Cassini probe took its deepest dive yet through the icy geyser erupting from Enceladus’ south pole. We’re getting our first pictures of the historic flyby back now, and naturally, they’re incredible.

At around 11:30 am EDT Wednesday, the Cassini probe sailed a mere 18.6 miles above the south pole of Enceladus, Saturn’s tiny, eruptive ice moon that’s become one of the most promising hideouts for alien life in our solar system. Enceladus’ south pole geysers are spewing frozen water from the moon’s subterranean, geothermally-heated ocean, offering free samples to any curious space probes that just happen to be in the neighborhood.

So on Wednesday, Cassini collected a droplet of that alien ocean water as it whizzed past the moon at 12,000 miles per hour. The probe is now busy analyzing that sample’s chemistry, searching for molecular hydrogen that could indicate a geothermal energy source. Within several weeks, we expect to get our first report back detailing just how potentially habitable this strange and beautiful moon really is.

Cassini was also snapping pictures as it sailed past the tiny ice world, dragging the open apertures of its narrow and wide angle cameras across Enceladus’ surface and shuttering like mad. The north pole was in day light and the south pole in darkness during the flyby, but in a way, that makes these pictures even more beautiful. They’re all illuminated by Saturnshine, light scattered off the billowy atmosphere of the nearby gas giant.

The images shown here are unprocessed, and NASA warns that they could contain artifacts. Nevertheless, they are marvelous, and right now I’m really wishing I lived three centuries in the future, when we will surely be holding the interplanetary winter Olympics on Enceladus. More unprocessed images from the flyby are available on the Cassini mission website.

Cassini will make a final flyby of Enceladus on December 19th before turning its attention to other Saturnian targets for the last two years of its mission. When the probe is nearing expiration, it’ll plunge into Saturn’s atmosphere and vaporize into a zillion tiny space probe atoms. Cassini, along with Enceladus itself, will essentially become a part of Saturn.
