The team is working to manually post a few of the images that are in the raw image cue. We know you're all waiting.. patiently..


Greatly. greatly, greatly appreciated.

New vistas on new worlds.... wow.

The mosaic shots look to be framed exactly as they predicted--that may bode well for the skeet shoot pointing accuracy.

This is never les than thrilling, is it? We sit here, staring at our screens, and then suddenly a picture appears of a place never seen by human eyes before, or at least never seen in such detail before... then another... then another.. and it's easy to forget that we all have reserved front row seats for the making of history here... just as it's hard to believe that out there, in the outside world, people are just going about their business completely unaware that signals are beaming back to Earth from halfway across the solar system, carrying with them portraits of an alien world that will one day be explored in person by men and women...

Seriously, doesn't it ever do anyone else's head in?!?!? ohmy.gif biggrin.gif

To echo what others have said this is greatly appreciated - thanks. This is one of the more exciting planetary/satellite flybys I can remember and I'm eagerly waiting for the ultra-closeups.

Several very interesting images of highly "wrinkled" terrain from ~20,000 km out like this one:

http://saturn.jpl.nasa.gov/multimedia/imag...iImageID=165849

Interestingly most/all are 2x2 binned (512x512 pixels).

A typical method they use for gathering color at a lower data volume cost and greater acquisition speed - one clear frame and several (usually 3) multispectral, binned frames. Problem is, this pesky line truncation can often reduce the vertical resolution by another factor of two if there's a lot of going on in the frame. There certainly is a lot going on in that frame you linked to, it caught my eye as the most interesting one so far, too. Can't wait to see that in full res.

Just for fun, trying to follow along with where these frames are. The graphics from the "looking ahead" article really help out a lot. I've downloaded each of the images from the south polar mosaic, de-interlaced them, and rotated them 180 degrees to match the orientation of the maps.

I second that, great work, Emily. I might as well quit looking at the raws page and just wait for them to appear at your page, all nice and dandy smile.gif

If I get it correctly, the highest resolution view will be somewhere in the top center portion of this footprint: http://planetary.s3.amazonaws.com/data/cas...N_di_rot180.png

Stu.... does my head in constantly. smile.gif

My workmates appreciate my enthusiasm, but simply do not FEEL the esctasy of the moment the way I do.
Every UMSFer has this spacer consciousness.... (well, if you did not, you would not be on this forum, would ya...duh) the only thing better would be to BE THERE IN PERSON.

We woke up this morning with these vistas unseen..... and soon a page in space history will turn and we see scenes
no human ever has.

It IS amazing.

Using Emily's page and planned imaging footprints, here's what I get for a rough location of the highest resolution 8 m/pix image:
Attached Image


The uncertainty of my location is probably something like +/- 0.5 NAC FOV on both axes. It'll be interesting to see where the actual footprint landed given the timing sensitive skit shoot.

Update: At 23:00 UTC, in 4 minutes, we'll have some additional images manually posted to the blog at http://blogs.nasa.gov/cm/blog/cassini-aug08/
and the saturn page at saturn.jpl.nasa.gov and the CICLOPS page.
