This collage of images taken by NASA's Cassini spacecraft on Dec. 2, 2016 shows Saturn's northern hemisphere and rings as viewed with four different spectral filters.

NASA's Cassini probe has beamed home the first close-up images of Saturn from the new phase of its venerable mission, and they're a doozy.

The photos — which you can check out in this Space.com video set to pulse-pounding music — show Saturn's northern hemisphere in spectacular detail, and provide multiple views of the huge, bizarre hexagonal storm that swirls around the planet's north pole.

Cassini captured the images on Friday and Saturday (Dec. 2 and Dec. 3), as the spacecraft was zooming toward a Sunday morning (Dec. 4) plunge past the outer edge of Saturn's iconic rings. This dive was the first of 20 that Cassini will perform during its "Ring-Grazing Orbits" phase, which runs through April 2017. [See More Photos of Saturn's Bizarre Hexagon]

On April 22, the spacecraft will fly past Saturn's largest moon, Titan, whose gravitational pull will reshape Cassini's orbit and set the stage for the mission's "Grand Finale." During this last act, Cassini will conduct 22 dives between Saturn and its innermost ring, whose edge lies just 1,500 miles (2,400 kilometers) from the gas giant's cloud tops.

The mission will come to an end on Sept. 15, 2017, when Cassini performs an intentional death dive into Saturn's thick atmosphere.

"This is it, the beginning of the end of our historic exploration of Saturn," Carolyn Porco, Cassini imaging team lead at the Space Science Institute in Boulder, Colorado, said in a statement today (Dec. 7). "Let these images — and those to come — remind you that we've lived a bold and daring adventure around the solar system's most magnificent planet."

The $3.2 billion Cassini-Huygens mission launched in October 1997 and arrived in the Saturn system in July 2004. The Cassini mothership carried a lander called Huygens, which touched down on Titan's surface in January 2005; the orbiter continued to circle Saturn, studying the planet, its rings and many moons.

The mission is a joint effort involving NASA, the European Space Agency and the Italian Space Agency.
