The last time we saw this reunion was here.

The long awaited official trailer for “In Saturn’s Rings” has been unleashed. Looking forward to this film for over three years now.
If you follow this blog on any basis, you might be well aware that a good percentage of the imagery is provided by our good flickr friend Gordan Ugarkovic. Here is a bit of what we missed from him in the last 10 months we were locked out.
Titan at the edge of Saturn taken 2011-05-21. Looks unreal. Like Titan was dropped into the scene using Photoshop. A sin I would never commit. See the lesser “official” NASA version released a few months back here.
Keeping with the theme of moons transiting Saturn. Here is Rhea and tiny Epimetheus doing what they do. Taken in 2010-03-24.
Finally, just to change it up… two moons against Titan, another of Saturn’s moons. Pictured above the Titanian cloud-tops is Dione on the left and Rhea on the right.
Space enthusiasts seem to really like shots that have more than one body in the same frame. How about five… or six (if you count the rings of Saturn)? Starting left to right that is Janus, Pandora, Enceladus, Mimas and Rhea.
Thanks again to Gordan Ugarkovic.
This is so nice, but I am furious that I didn’t get to design this. This is Information design at it’s best naturally by National Geographic. You can see 50 years of robotic planetary exploration at a glance. It even includes failed missions represented by darker desaturated lines. As far as I can tell the cream colored lines are US and the red ones are Soviet. Interesting to see how many of those lines go dark around Mars.
Now where does one purchase such a thing? Perhaps this month’s issue of NG? Here is the link to it on their site complete with zoom viewer and them some kind samaritan posted a hires version to flickr.
Another Gordan Ugarkovic. It never ends!
Some scientists believe that they have stumbled upon the first ever detected rings around a moon. As if that were not interesting enough — these theoretical rings would also be the only rings ever found around a body that is not a gas giant such as Saturn, Jupiter, Uranus or Neptune. As a matter of fact, Rhea isn’t even one of the larger moons of the Solar System. If these rings exist they are sparse and made of small particles, so Cassini is unlikely to ever detect these particles with the cameras its is equipped with. Therefore, there are no actual images to support this theory… but it is interesting enough that I feel compelled to at least point interested space fans to a great article explaining the theory on the Planetary Society’s blog.
NASA released an unusually large amount of color images to the Cassini website recently. Most of what is shown here on this site are actually images put together by freelance imagers who access the raw files and do some stitching together of filtered images. Color images coming straight off the Cassini website are a rare event, so when about 8 appeared in the gallery a few days ago… it was an unexpected gift.
A family portrait of the Saturn System. Moons visible in this image (you need to click the preview) are Dione at far left, Enceladus near the left side ring edge, Mimas a speck on ring shadows on the western limb, Rhea against the northern hemisphere, Tethys near the right ring edge, and Titan near lower right.
These images were taken of Rhea as it (and Cassini) sped across Saturn’s globe on August 30, 2007. The near-natural color images were composed from raw near-infrared, green and ultraviolet filtered files made available on the NASA-Cassini website. Some of the details may have been enhanced through the use of infrared and ultraviolet in place of red and blue… but they have been adjusted to reflect what we assume is closer to actual natural color.
