NASA’s Cassini mission may be entering its last several months now, but that doesn’t mean there aren’t any more cool science discoveries to be made. Some amazing new images were just posted of one of Saturn’s tiniest moons, Pan. This small asteroid-like object orbits Saturn within a gap in the rings and so is known as a ring moon. Scientists had a basic idea of what it looked like before, kind of like a walnut in earlier Cassini images, but the new images show it in much more detail and reveal how odd-looking it really is – more like a giant ravioli or dumpling. There have also been some incredible new close-up images of Saturn’s rings, as Cassini continues the Ring-Grazing Orbits phase of its mission. The images reveal intricate details never seen before in the structure of the rings.
As the Cassini spacecraft continues its journey through the Ring-Grazing Orbits, it has been sending back some incredible new images of Saturn and its rings, many in detail never seen before. The rings are composed of countless individual streams of particles, all held in place by Saturn’s gravity. Click to view full-size versions of the raw images.

The Cassini spacecraft has successfully completed its first close pass of Saturn’s ring system, part of the Ring-Grazing Orbits phase of its mission, NASA said yesterday. As might be expected, Cassini has sent back some spectacular new images; these first images show Saturn’s northern hemisphere in incredible detail, including the famous “hexagon” jet stream surrounding the north pole.
As reported earlier this week, the Cassini spacecraft is now preparing to make a series of very close passes by the edges of Saturn’s rings, known as Ring-Grazing Orbits. A couple days ago, Cassini conducted a close flyby of Saturn’s largest moon Titan; this is the second-to-last ever flyby of Titan before Cassini enters the Grand Finale phase of its mission, culminating in a deliberate plunge into Saturn’s atmosphere on Sept. 15, 2017. During this flyby, Cassini focused on mapping the surface and surface temperatures and used Titan’s gravity to help place the spacecraft into the Ring-Grazing Orbits.
The Cassini mission to Saturn has been one of the most successful planetary missions ever, revealing the ringed giant and its moons as never before. Sadly, that mission is scheduled to end Sept. 15, 2017, and in preparation the spacecraft will be making some never-done-before maneuvers as it gets ready to take the final plunge into Saturn’s atmosphere on that date, aka the Grand Finale. Next week, Cassini will perform one of these feats, flying just past the edge of Saturn’s main rings.
