Whoah, those are really cool images. Phil! Help! What/where are we looking at?
Speaking of Hyperion, I just noticed this little item in today's Significant Events Report. QUOTE Tuesday, July 17 (DOY 198): The final sequence development process for S34 kicked off today. The sequence is unusual in that it will be composed of four parts. The first part is similar to a normal background sequence but will run for only two weeks. This is followed by uplink and checkout activities for CDS version 10 flight software that will last for about a week and a half. During this time period there will be no science observations. After the conclusion of the CDS activities, a mini-sequence devoted to Hyperion observations will run for about four days. The last piece of S34 is again like a normal background sequence with full science activities. This will run for a little over a week, concluding on or about November 1. The Hyperion mini-sequence base products and stripped subsequences and the sequence products for the pieces of the S34 background sequence have been released for team review. Looks like the Hyperion close approach will be within about 120,000 km on October 21; and during the second week or so of October, there'll be no science data at all. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

You're looking at the big facet frequently seen before including in the highest resolution mosaic from the really close encounter. It's just that we have not seen such perfect low angle lighting before.
Incidentally, I don't think I ever posted this before: It's a cylindrical mosaic of Voyager images. This new pic is of the roughly circular patch on the left side. It was made by me with the assistance of my friend Alyson Ford. Phil -------------------- ... because the Solar System ain't gonna map itself.

Wow, that lump really does look different to me every time. I wish I had a shape model of Hyperion on my desk.

Neat animation. It really lets you see Hyperion as a faceted shape rather than a body that anyone could describe as "round."
Gordan, how exactly did you colorize this? --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Gordan, how exactly did you colorize this? I used my other color shots as reference, in natural color views there's virtually no color variation anyway. I simply applied a level balance in Photoshop that reduced the max brightness of the green channel to 238 (from 255) and blue to 219, thus giving the brownish-red hue and afterwards increased the saturation a tad.

You're looking at the big facet frequently seen before including in the highest resolution mosaic from the really close encounter. It's just that we have not seen such perfect low angle lighting before. I might be totally off my meds here, but I disagree. This feature looks like the prominent crater to the "southeast" (!?!) of the big facet seen during the targeted encounter (bottom center in your map). To illustrate: I think this is the bite out of the cookie (forgive me, my 4-year-old was doing impressions of you-know-who this morning). If I'm wrong Phil, you can pummel me with rocks, preferrably irregular and faceted. EDIT: D'oh! VP got it before I did. Unrelated bonus points in Io vs Europa deathmatch. I'll get you my pretty, if it's the last thing I do! (There's no defense against buckets of superheated sulphur. Appealing to UMSF High Council). -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...

That's a really helpful comparison, EC. Thanks!

You're absolutely right, EC, I had it upside down! Sorry about that. Can I get some of your meds?

You mean there's a "This side up" on Hyperion?

Sure thing! Be forewarned...upside-down won't get any better with them, but they do allow you to drive backwards. I ran over my own post fifteen minutes ago.
Edit: "This Side Up" on Hyperion remains sort of ambiguous. I suggest that Proteus is the box Hyperion came in, and that Ted has reprocessed the image enough that the lettering may finally be visible. -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...

Not daring for a moment to think I can compete with or compare my mucking about to the work already posted here, but I couldn't resist having a go at this Hyperion image myself, purely because it reminded me of the images DEEP IMPACT sent back from its target comet... anyone else think that?

Hi,
Quick map update for Tethys adding a medium-res image from the July encounter. I'll still want to figure out where the images in EC's hi-res mosaic (post #4) are located. Also thinking of the earlier Ithaca Chasma mosaic... http://laps.noaa.gov/albers/sos/sos.html#TETHYS -------------------- Steve [ my home page and planetary maps page ]
