Saturn and 4 Icy Moons in Natural Color

This approximate natural-color image shows Saturn, its rings, and four of its icy satellites. Three satellites (Tethys, Dione, and Rhea) are visible against the darkness of space, and another smaller satellite (Mimas) is visible against Saturn's cloud tops very near the left horizon and just below the rings. The dark shadows o...

Taking a Bite Out of Tethys

Dione steps in front of Tethys for a few minutes in an occultation, or mutual event. These events occur frequently for the Cassini spacecraft when it is orbiting close to the ringplane

In the Company of Dione

Explanation:
That is not our Moon. It's Dione, and it's a moon of Saturn. The robotic Cassini spacecraft took the featured image during a flyby of Saturn's cratered Moon last month. Perhaps what makes this image so interesting, though, is the background. First, the large orb looming behind Dione is Saturn itself, faintly lit by sunlight first reflected from the rings. Next, the thin lines running diagonally across the image are the rings of Saturn themselves. The millions of icy rocks that compose Saturn's spectacular rings all orbit Saturn in the same plane, and so appear surprisingly thin when seen nearly edge-on. Front and center, Dione appears in crescent phase, partially lit by the Sun that is off to the lower left. A careful inspection of the ring plane should also locate the moon Enceladus on the upper right.

Explanation:
What's happening in this strange juxtaposition of moon and planet? First and foremost, Saturn's moon Dione was captured here in a dramatic panorama by the robotic Cassini spacecraft currently orbiting the giant planet. The bright and cratered moon itself spans about 1100-km, with the large multi-ringed crater Evander visible on the lower right. Since the rings of Saturn are seen here nearly edge-on, they are directly visible only as a thin horizontal line that passes behind Dione. Arcing across the bottom of the image, however, are shadows of Saturn's rings, showing some of the rich texture that could not be seen directly. In the background, few cloud features are visible on Saturn. The featured image was taken during the last planned flyby of Dione by Cassini, as the spacecraft is scheduled to dive into Saturn's atmosphere during 2017.

Explanation:
Orbiting in the plane of Saturn's rings, Dione and the other icy saturnian moons have a perpetual ringside view of the gorgeous gas giant planet. Of course, while passing through the ring plane the Cassini spacecraft also shares their stunning perspective. The rings themselves can be seen slicing across the bottom of this Cassini snapshot. Remarkably thin, the bright rings still cast arcing shadows across the planet's cloud tops. Pale Dione, in the foreground, is about 1,100 kilometers across and orbits over 300,000 kilometers from the visible outer edge of the A ring.

In celestial mechanics, the #Lagrange points (also Lagrangian points, L-points, or libration points) are points of equilibrium for small-mass objects under the influence of two massive orbiting bodies - in this case #Saturn and larger moon #Dione.

Evander is located in the unmapped southern section of Dione in that USGS map. The map could have been extended towards both poles using low resolution images. This isn't the only large impact basin which escaped notice in Voyager images. I already mentioned Tethys in that respect. Tomorrow we will see another example... but I'm saving the best until last. #Saturn #Voyager #Dione

Those images of Dione are hiding something. Here is one of the distant images enlarged to show an oblique view of a 300 km diameter circular impact basin. It's now called Evander. Here is a Cassini map with names:

And here is my 2002 LPSC abstract on its discovery:

https://www.lpi.usra.edu/meetings/lpsc2002/pdf/1553.pdf

I presented this but never wrote it up, being bogged down in much bigger projects at the time (and ever since).

#maps #Saturn #Voyager #Dione

This is the full set of useful images of Dione (by useful I mean useful for geology, not distant navigation images or very narrow crescents). The top set of 13 images are Voyager 1, the last 5 are Voyager 2. It's a beautiful world with craters, fractures and bright streaks. One image does not have a typical dark background - it was imaged against Saturn itself. #Saturn #Voyager #Dione

Moving on to Dione - I didn't make a map but here is a US Geological Survey airbrushed map made using Voyager images. I loath this map projection but 40 years ago it was very fashionable because it made it easy to compress digital files, back when it mattered how big a file was. The distortions along the diagonal sides are horrible. But it shows image coverage. The poles are missing. That bit of the equator not shown is not really missing, as we will see. #maps #Saturn #Voyager #Dione
