Phil Stooke<p>The second image of Tethys shows a white circle, seen in better images to be a large impact basin called Odysseus. It was identified immediately in Voyager images. But there is a second large circular basin seen only in the image at left, lying under and to the right of that large valley (Ithaca Chasma). That was not noticed at the time and was only identified in these specially processed images:</p><p><a href="https://www.lpi.usra.edu/meetings/lpsc2002/pdf/1553.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">lpi.usra.edu/meetings/lpsc2002</span><span class="invisible">/pdf/1553.pdf</span></a></p><p><a href="https://mastodon.social/tags/Saturn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Saturn</span></a> <a href="https://mastodon.social/tags/Voyager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voyager</span></a> <a href="https://mastodon.social/tags/Tethys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tethys</span></a></p>
Phil Stooke<p>A bit more on Tethys as seen by the Voyager missions. Here are two images, Voyager 1 on the left, Voyager 2 on the right. The best Voyager images were of the other side of Tethys. The dark streak is curious - it extends around half of the equator. Explanations in the journals include impacts by E-ring particles, electrons in the magnetosphere and ejecta from the two co-orbital moons of Tethys. </p><p><a href="https://mastodon.social/tags/Saturn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Saturn</span></a> <a href="https://mastodon.social/tags/Voyager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voyager</span></a> <a href="https://mastodon.social/tags/Tethys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tethys</span></a></p>

Phil Stooke<p>A closer image from Voyager 2 shows something of what's happening. Here Penelope has the shading we expect from sunlight - bright on the right, dark on the left. But it's subdued. The dark coating nearly balances the brighter sunlight. In the lower resolution image from Voyager 1 the two effects (albedo and illumination) cancel each other out and Penelope disappears. The dark material acts like it is sprayed on. Other topography shows the same effect. <a href="https://mastodon.social/tags/Saturn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Saturn</span></a> <a href="https://mastodon.social/tags/Voyager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voyager</span></a> <a href="https://mastodon.social/tags/Tethys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tethys</span></a></p>
Phil Stooke<p>What's up with Penelope? Here are three images from Voyager 1, watching Tethys rotate. Penelope is in the left and middle images but where is it in the right image? And the shading on the crater wall - in the middle there should be no shading, the Sun's overhead. </p><p>Whatever that dark stuff is to the west (left) of Penelope, some of it has darkened the eastern (right) wall of the crater. The opposite wall of the crater was not darkened, as if sheltered from the dark material. <a href="https://mastodon.social/tags/Voyager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voyager</span></a> <a href="https://mastodon.social/tags/Tethys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tethys</span></a></p>
Phil Stooke<p>Here is a Voyager 2 image of Penelope, a prominent crater on Tethys. The processing here exaggerates albedo variations. If you were there it would look much less contrasty. The big crater is Penelope, and it looks pretty much as you would expect a crater to look, and like all the smaller craters seen best around the top of the disk. Sunlight makes one wall bright, the other is shaded. But that's wrong - look where it is. The Sun should be overhead. <a href="https://mastodon.social/tags/Saturn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Saturn</span></a> <a href="https://mastodon.social/tags/Voyager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voyager</span></a> <a href="https://mastodon.social/tags/Tethys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tethys</span></a></p>

Phil Stooke<p>A few quick observations. We see dark markings in two areas, one running part way round the equator (top and middle rows), the other opposite it and more extended north-south. The second one is redder than the first (not visible in my B/W versions). Note the prominent crater Penelope in the top right image, the first in the 2nd row, and in images in the bottom 2 rows. There's something very peculiar about Penelope - as we will see tomorrow. <a href="https://mastodon.social/tags/Saturn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Saturn</span></a> <a href="https://mastodon.social/tags/Voyager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voyager</span></a> <a href="https://mastodon.social/tags/Tethys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Tethys</span></a></p>
Continued thread

On to Saturn's moons now. My intention was to get the most out of Voyager images before Cassini arrived. The best Voyager images are often seen but there are others with very interesting stories to tell. We'll start with Tethys. This image is a sort of index to the full imaging dataset for Tethys. Each image has been treated as I did for Ariel and Umbriel - the shading gradient caused by its spherical shape is suppressed and local features are enhanced. #Saturn #Voyager #Tethys

Ich bin ziemlich in Verzug mit meinem #startrek Voyager-Folge gucken und dazu eine Folge #Missionlog-Podcast hören. Gute 10 Folgen…
Das liegt wohl daran, dass ich #Voyager einfach nicht gut finde. In fast jeder Folge denke ich: „Was?! Warum?! Ihr seid so blöde…“
Ich finde Die Serie einfach meistens nicht interessant, möchte mein Projekt aber nicht aufgeben. Ich muss irgendwie einen StarTrek-Marathon hinlegen…
